Sharing a platform with the Audi Q7, an ICE with the Audi S4, the crossover Cayenne S Hybrid is the product of ingenuity, and Porsche’s first venture into the hybrid scene.

The Cayenne S Hybrid is a parallel full hybrid, it has a 3.0-liter DOHC V6 to a 47-hp electric motor/starter/generator powered by a 240-cell NiMH (nickel metal hydride) battery pack, weighing a meager 152 pounds and producing a peak 288 volts. The powertrain provides 380 bhp and 427 lb-feet of torque. “The battery pack fits in the former spare-tire well. An eight-speed Tiptronic automatic transmission, with two overdrive gears, is a subtle snub to new-fangled CVTs.”

“Porsche adds eco-friendliness to the Cayenne’s elegant performance.” With an EPA estimated 24 mpg (combined), it allows coasting up to 97 mph using only electric power. The Cayenne can travel on all-electric power up to 31-40 mph. And like most hybrids, the Cayenne employs regenerative braking and a stop/start ICE function. “Two power modes, E-power (all-electric) and E-boost (complementary electric boost) complete the package.”

And following Porsche’s tradition it’s lavishly strewn with interior components including HD infotainment interface, Bluetooth/USB capability, adaptive cruise control, navigation system, 16-speaker, surround-sound audio system with rear DVD display, and rear-view park assist. Lastly, “The Cayenne S Hybrid features a cornucopia of front and rear airbags, 4-wheel ABS, braking assist, sturdy A-pillars, traction control, stability control and a TPMS, all to protect its 4,398-pound body.”

The 2010 BMW ActiveHybrid X6 is the product of expensive and unsuccessful partnership with Daimler/Chrysler and General Motors in creating a hybrid-electric powertrain that would be suitable for use in large, heavy trucks and SUVs.

It employs a transmission that operates like a seven-speed automatic and utilizes two electric components that come on either independently at low speeds or in concert with the gasoline engine. This makes its total horsepower to 480 while torque reaches 575 ft-lbs from 1750-4500 rpm. Like any other hybrids, the X6 use regenerative braking that helps recharge that large battery pack mounted under the rear cargo area.

Aesthetically speaking, the ActiveHybrid gets unique 20-inch five-spoke Aero wheels and an exclusive Blue Water Metallic paint choice. It also has extra badges on the doors and rear tailgate. Inside, the X6 has comfortable seating for four and sloping rear roofline that trims huge amounts of space from the rear cargo area.

All in all, the BMW ActiveHybrid X6 is a solid vehicle that can accommodate the whole family with its spacious cabin and cargo area. It’s also a perfect ride for long road trips with its superb powerplant.

The Mitsubishi RVR is a crossover vehicle that was released in Japan last February. Mitsubishi planned it to be a global model that is why it is expected to hit U.S. shores this fall. When it goes stateside it’s going to adapt the ASX nameplate. Aside from its name, there are also some changed lined up for the RVR Crossover. But for the meantime, the RVR compact crossover is equipped with a 1.8-liter, 16-valve DOHC MIVEC engine with INVECS III sport mode 6-speed CVT.

The vehicle features a regenerative braking system*3 (high-efficiency electric power generation control), electric power steering, improved aerodynamics and other low-fuel consumption technologies down to fine detail, resulting in a 75% reduction from the Japanese FY 2005 emissions gas standards and exceeding the FY 2010 fuel efficiency requirements by 15%. All models qualify for the Japanese eco-car tax reduction (50% tax reduction to promote the popularization of environmentally-friendly cars).
The RVR also incorporates super-wide HID headlights which provide a wide, ultra-bright beam for safe night driving, a panoramic glass roof (with LED illumination) for a sense of spaciousness during the day and a romantic ambiance at night, and push-button ignition. The vehicle has a refined and sporty interior with a black color scheme, silver highlights, and smooth, soft padding.
The RVR is equipped with an advanced in-car entertainment including a terrestrial digital TV tuner HDD navigation system and a “link system” with USB, Bluetooth and other connections for music players and other external devices.
*1. Mitsubishi Innovative Valve-timing Electronic Control
*2. Intelligent and Innovative Vehicle Electronic Control System
*3. Intensive battery charging of the electricity generated during deceleration (regenerative braking). The stored energy is used until it is consumed during idling and running, without electricity generation. This system contributes to higher fuel efficiency because the burden on the engine is decreased from not running the alternator while the stored energy is consumed.

With all these features, this crossover looks like a great choice for people who want superior road performance, fuel efficiency, convenience, and luxury.

Surprise, surprise! Chevrolet unveiled a new variation of the Volt electric vehicle, the Volt MPV5. This model is a crossover that can seat up to 5 persons. Compared to the sedan version of the Volt, the MPV5 is 7-inches longer, 7-inches higher, and 2.9-inches wider. According to reports, the Volt MPV5 will also have Voltec powertrain and will be powered by the same t-shaped 16 kWh lithium ion battery. It is also equipped with a 1.4-liter gasoline range extender that serves as a backup in case the battery runs out and can’t be charged immediately.

The new Chevrolet MPV5 looks like the perfect vehicle for the family. It’s size and capacity for passengers gives it the right appeal for the family.

GM has a very important statement regarding this MPV, “The Volt MPV5 concept demonstrates the flexibility of the Voltec propulsion system, which can produce enough electric power to propel a range of vehicles. From a compact sedan like the Volt to a crossover like the Volt MPV5 concept.” 

I have to admit, the Volt MPV5 looks great. What do you think?

You’re wrong if you think that the Audi Q7 can’t improve any more. The 2011 Audi Q7 has undergone a major overhaul, in the engine anyways. Audi replaced its 3.6-liter V6 and 4.2-liter V8 with the supercharged TFSI 3.0-liter V6. This engine is capable of producing up to 272 hp and 295 lb-ft of torque. This engine is matched with an 8-speed tiptronic transmission that offers a more speed ratio for an improved cruising experience. This transmission also helps improve fuel economy.

The 2011 Audi Q7 seems like a great for those who are looking for a car that delivers great performance, handling, and interior comfort.

Anyway, here are the specifics about the 2011 Audi Q7 technology:

Improved 3.0 TDI now with start-stop
The diesel line-up has also been extensively reworked, the most notable changes benefiting the 3.0-litre V6 TDI, which in its latest form is essentially new from the ground-up, and 20kg lighter as a result. Constructed using a complex new cylinder wall machining process that reduces friction, and aided by newly introduced engine start-stop technology, the second generation V6 employs an even more responsive turbocharger, an enhanced common rail fuel injection system and new chain-driven timing gear to deliver a 19 per cent improvement in fuel economy compared with its predecessor.
In the combined cycle test it achieves 38.2mpg, which equates to an impressively low CO2 output of 195g/km, yet with a rated output of 240PS and a constant 550 Nm of torque available all the way from 1,750 to 2,500 rpm, it is also capable of powering the Q7 from rest to 62mph in 7.9 seconds – a 0.6-second improvement - and on to a top speed of 135mph.
World’s cleanest diesel technology
The world’s cleanest diesel engine technology is of course also a feature of the latest Q7 range in the continuing Q7 3.0 TDI Clean Diesel, which not only already meets more stringent EU6 exhaust emission limits that are not due to come into force until 2014, but also tough US regulations. Special combustion chamber sensors and a DeNox catalytic converter in the exhaust system further reduce oxides of nitrogen by means of an additive. The 3.0 TDI clean diesel also develops 240PS and has an impressive 550 Nm torque output between 2,000 and 2,250 rpm. It takes the Q7 from a standstill to 62mph in 8.1 seconds, 0.4 seconds more quickly than before, and gives it a top speed of 135mph. Thanks to the new tiptronic transmission it works with, combined fuel economy works out at 33.6mpg, a six per cent improvement over the original version, resulting in an impressive drop in CO2 from 234g/km to 219g/km.
The Q7 4.2 TDI also benefits from an improvement in fuel economy, up from 28.5mpg to 30.7mpg, thanks to the new cylinder wall construction methods and the upgraded common rail injection system. The 340PS V8 diesel also delivers 40Nm more torque than before, with an impressive 800 Nm on tap between 1,750 and 2,750 rpm. The big TDI engine gives the Q7 distinctly sporting performance figures, powering it to 62mph in 6.4 seconds and on to a top speed of 150mph.
Eight speeds now standard
A new automatic transmission has also been instrumental in the achievement of considerably greater efficiency in the latest Q7. Based on the original six-speed tiptronic, but with another friction-clutch shift element added, the new eight-speed transmission improves fuel economy by around five per cent. Drivers can choose between ‘D’ and ‘S’ modes, or make their own gear shifts in ‘manual’ mode via the gear lever or the optional steering-wheel paddles. Shifts are quick, well judged and delivered with a smoothness that befits this luxury seven-seat SUV, and the wider spread of ratios made possible enables the engine to operate at lower revs in the higher gears, adding to the relaxed feel and helping to reduce fuel usage.
All-wheel-drive reassurance
The new transmission channels power to the four driven wheels via the quattro permanent all-wheel-drive system with the now familiar 40 per cent / 60 per cent front-to-rear torque split for optimum on-road balance. Both on and off the tarmac, the standard five-mode air suspension with its variable ground clearance of between 180mm and 240mm helps the Audi Q7 to iron out surface imperfections. The off-road setting, with 205mm of clearance and adapted damper control, is the perfect setting for cross-country driving.
Inside, the latest Q7 contrasts its rugged exterior with an opulently trimmed cabin that as before can be equipped to up to three specification levels depending on version. Standard, SE and S line options are offered for the 3.0 TFSI 272PS and V6 TDI models, while the 3.0 TFSI 333PS and V8 TDI versions are available exclusively in SE or S line form.

Acura introduces the market with a crossover that would break the mold of a crossover. Confused? Well, the said automaker has a new vehicle called ZDX that sprouts interest for lots of car enthusiasts. Simply put, it’s a two-door, coupe-styled sedan mixed with the functionality of a CV that’s made for “well-off middle-aged couples who really have no need for those rear two doors.” So basically, it’s a crossover for those people who don’t need a crossover. Did that made sense? And although the design and overall construction exhibits impracticality here and there, the vehicle is not a bad choice for newly weds (or not so new) who are in no hurry to have kids.

The 2010 Geneva Auto Show later this week is set to feature the new and sixth version of the famous Volkswagen Golf, infused with the style of a crossover. Aside from raising the car’s ground clearance by 20mm that would definitely help in the off-road, the CrossGolf boasts a rugged exterior with new front and rear bumpers, side skirts, roof rails, fender flares, and specially designed 17-inch wheels.

As for engines, it’s the usual VW powerplants consist of TDI and TSI engines. The TDI engine includes a 105-hp 1.6-liter and a 140-hp 2.0-liter with 236 ft-lbs and a rating of 44.4 mpg. While gasoline engines include 105-hp and 122-hp TSI mills as well as an impressive 160-hp 1.4-liter TSI Twincharger with both a supercharger and turbocharger.

Well, we just have to wait for a few more days for more reactions (violent or not) from the Geneva Auto Show for this Volkswagen CrossGolf.

Wanna know more? Here’s the Press Release:

PRESS RELEASE

INFINITI GOES DIESEL … QUIETLY

* Bespoke new 3.0-litre V6 direct injection diesel
* Class leading torque output of 550Nm
* Exceptional refinement…
* … with outstanding performance…
* … competitive CO2 emissions and economy…
* … add up to a true Infiniti performance diesel
* Alliance designed engine for new EX30d, FX30d and M30d models
* Sales due to start in the summer, prices to be confirmed
* Diesel opens new opportunities for Infiniti

ROLLE, Switzerland (February 19, 2010) – Phase two of Infiniti’s quiet assault on the European luxury car market is underway with the arrival of a newly developed 3.0-litre V6 diesel. The engine, the first in the brand’s 20 year history, has been specifically designed to deliver high levels of refined performance in line with Infiniti philosophy. It will initially be available in both the acclaimed EX and FX crossovers and later in the Infiniti M luxury performance sedan.

The new diesel is a key element to Infiniti’s continued growth in Europe. Launched barely a year ago, the Infiniti range has won high praise from customers and the motoring press alike. Now with five established model lines – G37 saloon, coupé and convertible, plus the EX and FX ranges – more than 2000 Infinitis have been sold across 15 markets despite the marque’s launch coinciding with the worst global recession for decades.

A sixth model, the Infiniti M Line, will be launched during 2010 and it, too, will be available with the choice of petrol and the new 3.0d unit.

“The sales success enjoyed by Infiniti in Europe against a backdrop of financial uncertainty proves the cars’ appeal to a discerning audience. We have established Infiniti as the luxury performance brand thanks in part to the remarkable multi-award winning VQ petrol engine that powers most of the models in the range,” said Jim Wright, Vice President, Infiniti Europe.

“We were aware from the outset, however, that for Infiniti to offer a complete range a powerful diesel engine was a must, especially in the European premium SUV market where diesel represents the bulk of sector sales.

“Although we did investigate the possibility of adapting an existing large capacity diesel for Infiniti, we quickly established that nothing on the market met our exacting requirements. We needed an engine that delivered not just stunning performance but exemplary refinement too. For that reason, with the Alliance we decided to develop our own engine, a performance diesel worthy of the Infiniti badge,” said Wright.

The performance figures speak for themselves. Developing 175 kW (238 PS) and a remarkable 550 Nm of torque, with standard seven-speed automatic transmission the new engine sends the EX30d to 100 km/h from rest in 7.9 secs and the FX30d in 8.3 secs. However with all that torque, it is in their overtaking performance that the Infiniti’s advantage will be most felt. (All figures subject to final homologation.)

The V6 diesel in detail
Designated V9X, Infiniti’s new V6 diesel has been developed in Europe by Infiniti engineers working with other engineers from Renault and Nissan. It is made at a state-of-the-art facility in Cleon in France, some 100 kms west of Paris. From the very start of development, the new unit was created to answer Infiniti’s demands for a powerful but exceptionally refined diesel engine, quiet enough in use to match the high standards set by the petrol engine.

The unit will also be used in cars from Renault and Nissan, allowing both those brands to broaden the appeal of specific model ranges at the same time as boosting production volumes of the engine. Unusually, V9X will power front-wheel drive, rear-wheel drive and four-wheel drive models.

With Infiniti’s specific requirement for a compact unit delivering high levels of power and torque with competitive emissions, strong economy and unrivalled refinement leading the development, work on the direct injection 2993cc V6 began in 2005.

Although a V8 diesel engine was investigated, the V6 format was identified early on as the ideal layout for the unit, providing the optimum balance between overall performance, refinement and volume potential across the three Alliance brands. Target performance was 238 PS (175 kW), 500 Nm of torque and early compliance with forthcoming Euro 5 emission legislation.

At the same time, the engine bay architecture of the EX and FX models – designed initially as petrol models only – called for a compact engine which, if it were to be used in both transverse and longitudinal positions, would need to have a comparatively narrow vee angle as close to 60 degrees as possible.

Engineers decided that the ideal vee angle for the unit would be an unusual 65 degrees. This offered an excellent compromise between crankshaft balancing, crankshaft and cylinder block reliability and engine packaging with the 65 degree angle wide enough to allow the single turbocharger to be neatly mounted within the vee.

But perhaps the key element to the success of the new V6 is the material chosen for the engine block. While some rivals tend towards aluminium-alloy cylinder blocks to reduce the weight of their diesel engines, development engineers felt that to achieve the desired levels of refinement an aluminium block would need extra material added to increase its stiffness and reduce noise levels. It might also need extra complexity added in the form of balancer shafts to boost refinement, but all these additions negate the weight advantages of an alloy block.

Conventional cast iron, however, would place too much weight over the front wheels and lower the levels of driving pleasure offered by all Infiniti vehicles. In its place, the engineers chose Compacted Graphite Iron (CGI), a material that offers all the benefits of cast iron and more – it has higher levels of stiffness and noise absorption – but without the weight penalty. And while CGI is heavier than a pure aluminium block there is no need to add stiffening ribs or extra sound deadening material so the weight gain is comparatively modest.

CGI was patented in 1949 and its first commercial application was for the brakes of Europe’s high-speed trains. It is 75 per cent stronger and up to 75 per cent stiffer than grey iron, the most common form of cast iron found in engine cylinder blocks. It also performs better than aluminium at higher temperatures when it is up to five times more fatigue resistant. Best of all, the weight of a typical engine block can be more than 20 per cent lower than an equivalent cast iron block.

To manage the high loads on the engine structure commensurate with the impressive power and torque outputs, the overall stiffness of the engine structure was optimised at the design stage by incorporating a number of specific features. These included a large and stiff coupling face between the converter housing and the engine; the CGI cylinder block with semi-deep skirts; direct bolting of ancillaries on the crankcase; an integrated engine bracket in the upper timing covers; a structural oil pan; a stiff torque converter housing and an axial driveline bearing on the gearbox side.

At the same time, to reduce vibrations inherent in a diesel engine and avoid unwanted resonances in the rev range, intensive structural optimisation during the preliminary design stage used finite element calculation to identify both the source of vibrations and to establish the ideal structural form of the block.

The result is a compact, architecturally stiff and refined unit that by itself delivers two of Infiniti’s design goals: high levels of refinement and no loss of chassis balance. In tests, Alliance engineers have determined that the V9X engine has the lowest 250 Hz and 500 Hz vibrations of all the benchmarked engines.

The main dimensions of the unit are:
Cylinder arrangement V, six cylinders
Displacement 2993cc
Bore x stroke 84 x 90 mm
Bore pitch 92 mm
Vee angle 65 degrees

To ensure it fitted under the bonnet of both the EX and FX models, there are a number of significant differences between the Infiniti engine and its ancillaries and the version used in front-wheel drive applications. A number of changes also had to be made to the engine bays of the EX and FX.

As used in Infiniti models, the engine has a different cylinder block, a new design of crankshaft as well as new or revised intake manifold, fuel injection system, exhaust gas recirculation, turbocharger, oil sump and manifold catalyst. It is tuned differently, too, for more responsive performance and is ‘dressed’ differently, in keeping with the visual identity and design expression of the Infiniti brand.

Differences between petrol and diesel versions of the EX and FX models are equally far reaching and include a new front subframe, different front bumper designs to enhance air flow into the engine bay as well as redesigned sheet metal within the engine bay to house additional radiators needed for cooling.

The next phase of the engine’s development was to achieve the high levels of performance demanded by Infiniti owners. The result is a clean sheet design that takes current direct injection technology to a new level. Combustion chamber design has been optimised to improve the balance between emission levels and fuel efficiency and the compression ratio has been lowered to 16:1 to benefit not just economy and emissions but also noise, vibration and harshness (NVH).

The depth of the cone-shaped valve pockets have been reduced and a mini-sac seven-hole injector nozzle adopted while the bowl diameter has been widened and the spray angle adapted accordingly for a better swirl effect at the same time as reducing thermal losses. Internal engine friction is reduced by the use of ultra smooth components such as the micro-finished forged steel used for the crankshaft.

Class leading levels of torque and highly competitive specific power outputs are delivered thanks to the adoption of a comparatively large single turbocharger, which is mounted within the vee of the engine, an intercooler and the use of the latest generation of Bosch common-rail fuel injection. This system incorporates piezo injectors and operates at 1800 bar.

Power output is bang on target at 175 kW (238 PS) while the class-leading torque output of 550 Nm (for rear and four-wheel drive applications) is better than the target. Better still, peak torque is achieved from as low as 1,750 rpm and is available all the way to 2,500 rpm, while as much as 500 Nm is available from a mere 1,500 rpm. Idle speed is an exceptionally low 650 rpm with none of the NVH usually associated with a diesel.

The result is strong low-end performance with comfortably refined delivery. Throttle response is exemplary and although noise is kept to a minimum, special tuning of the exhaust note provides a pleasantly sporting note at about 2,500 rpm under hard acceleration.

Engine refinement is complemented by Infiniti’s smooth seven-speed automatic transmission, standard on both EX and FX, which has been tuned to take full advantage of the high levels of torque.

“Whether at idle or at 2,000rpm such is the refinement of the new diesel engine that the only way a driver will know what’s under the bonnet is by looking at the rev counter and seeing where the red line falls,” said Wright.

Performance and construction
Power 238 PS/ 175 kW
Torque 550 Nm from 1,750-2,500 rpm
Intake system VN turbocharger and intercooler
Injection system Common rail, 1800 bar and piezo injectors
Compression ratio 16:1
Camshaft drive DOHC, chain and pinion with mechanical lash adjuster
Valve drive Roller finger follower and hydraulic lash adjuster
Valves per cylinder 4
Cylinder head/block Aluminium/CGI

With performance meeting or exceeding the design goals, the final stage of engine development was to ensure the V6 met or exceeded emissions and fuel efficiency targets, including achieving Euro 5 compliance. In addition to the advances made by the changes to the combustion chamber, the V9X engine also incorporates a number of innovative features designed both to enhance emissions performance and improve reliability.

Among these is the adoption of an overcooled Exhaust Gas Recirculation (EGR) system which reduces NOx emissions. The system incorporates an integrated exhaust gas by-pass in the EGR cooler which quickly helps to achieve the optimum temperature after start up so that the full cooling capacity can be used. This features a low temperature water circuit for the EGR cooler to reduce still further the temperature of the exhaust gas and lower carbon monoxide and hydro carbon emissions.

Equally significant is the treatment of the tailpipe emissions. The system comprises a metallic oxidation catalytic converter offering lower pressure loss compared to a ceramic system and an exothermic catalyst and a catalytic diesel particulate filter (DPF) in the same container. The latter arrangement works in conjunction with a seventh fuel injector which is positioned in the exhaust.

This is activated while the particulate filter is being regenerated – a process of which the driver is completely unaware – but significantly means the opportunity for unburnt fuel to pollute the engine oil is removed. It also allows the filter to be regenerated in low-load conditions, such as idling, and therefore achieves a high efficiency level under all driving conditions at the same time as permitting oil change intervals to be optimised.

As well as high levels of performance and superb refinement, the V9X engine cuts CO2 emissions in the EX to 224 g/kms and helps the model return a combined fuel figure of 8.4 l/100kms. The equivalent figures for FX are 240 g/kms and 9.0 l/100kms.

Reliability and quality targets during development included more than 12,000 hours of durability testing on test benches while transverse and longitudinal V9X development engines were driven more than 1,250,000 kms. In addition every single engine is run on a ‘hot bench test’ cycle before it is delivered to the vehicle assembly plant.

“When we introduced Infiniti to Europe we knew our first task was to establish the brand as the pre-eminent luxury performance marque with the highest possible levels of service and aftercare.

“Now we can move on to the next step in Infiniti’s development. The new diesel engine allows us access to a far greater sector of the market without compromising on our core values. More than that, it’s an exceptional engine, with impressive torque from very low revs helping to deliver progressive, linear acceleration with none of the typical disadvantages of unwanted noise and vibrations.

“By creating a bespoke sporting diesel, we have been able to maintain the combination of performance and luxury expected from an Infiniti with the added bonus of lower emissions and improved fuel economy. It’s a win-win position,” said Jim Wright

Mitsubishi has unveiled a new concept car that would be very suitable for a family who is always on the go. And take note that this new vehicle is also environment friendly. Families who choose it as their family car will contribute in lessening pollution. The Mitsubishi PX-MiEV is a compact-sized four-wheel drive crossover hybrid that gets its power from a 1.6-liter petrol engine and two matching electric motors. One of these electric motors gives power to the front wheels while the other one power up the rear.

This car was unveiled at the Tokyo Motor Show. Mitsubishi specifically touted this crossover’s “environmental and on-road performance.” This combination will definitely attract people who want excellent car performance without harming the environment.

Check out this Press Release if you want to get the know this concept car a little bit better.

PRESS RELEASE:Concept: The new Mitsubishi Plug-in Hybrid System brings a major increase in range and environmental performance

 

The MITSUBISHI Concept PX-MiEV is a concept for a new-generation plug-in hybrid crossover that delivers both
outstanding environmental and road performance. Extending the active range of the i-MiEV city car, this concept also satisfies the need for mobility that combines occupant comfort with powerful performance.The MITSUBISHI Concept PX-MiEV is powered by the all-new Mitsubishi Plug-in Hybrid System which is designed primarily to drive the vehicle in all-electric mode while using a gasoline engine to generate electricity and to assist the electric motors as and when required.

Depending on the energy remaining in the drive battery and on driving conditions, the system automatically switches between three drive modes: all-electric EV, on-the-move generating EV, and Motor + Engine. The system allows the MITSUBISHI Concept PX-MiEV to return super-low fuel consumption figures. The concept is fitted with Mitsubishi’s new S-AWC (Super All Wheel Control) advanced vehicle handling control system that is built around torque and braking control at each wheel and incorporates electronically-controlled E-AYC (Electric-powered Active Yaw Control) which uses a differential motor to control rear wheel torque split.

Among the many features that makes this concept car the crystallization of Mitsubishi Motors’ wealth of automotive environmental technology is the cocochi-interior which embraces occupants in a very comfortable and healthy cabin environment. Providing very high levels of both environmental performance and economy, the MITSUBISHI Concept PX-MiEV stands apart from conventional hybrids that rely mainly on engine power as it significantly extends the possibilities offered by the EV.

Exterior Design

 

 

Pared-down looks give the new plug-in hybrid a simple and clean shape, producing refined looks expressing Mitsubishi Motors’ new crossover design Solid, Safety, and Simple were the keywords that drove the development of the MITSUBISHI Concept PX-MiEV ’s exterior design. The design team has created a clean and simple appearance for a new-generation crossover that visually sets it apart from conventional SUVs. The use of flush surfaces for the whole body eliminates virtually all projections to create a neatly-integrated one-piece design and at the same time lowers the impact to pedestrians in
the event of a collision.The front end locates the headlamps, air intakes and other functional parts within the graphics that center on the 3-diamond Mitsubishi logo in the middle of the grille to produce a simple but distinctive appearance. Styled to harmonize with the emblem, the front grille displays the advanced and high-tech qualities of the vehicle as well as presenting Mitsubishi Motors new crossover design identity.

The rear end styling is also designed around the 3-diamond emblem and distinguished by graphics that encompass
the full perimeter of the tailgate, giving the car a distinct personality while also projecting high-tech looks.

The LED headlamp and rear combination lamp units not only accent the advanced looks of the car but also improve its environmental performance through lower power consumption, longer service life and the elimination of the use of any mercury. Technical development of the headlamp LED emitters means they now project a highly visible beam that is very close to neutral white in color. The fast-illuminating brake light LED units contribute to enhanced safety performance.

The body uses new high-tech coloring that brings out a distinctive metal-like look. Combining elements of both spoke and dish styling, the geometric road wheel design highlights the sense of newness and at the same time optimizes air flow over the brakes to improve heat dissipation as well as improving aerodynamic characteristics at higher vehicle speeds.

Interior Design
Ergonomic, simple, classy design gives cabin soft wraparound appearance

 

 

The interior uses high-grade nubuck leather lining throughout and a high-contrast rich purple/off-white two-tone color scheme to create a comfortable space that melds choice quality with sophisticated and advanced design. The wraparound design of the cockpit and the excellent location and hold provided by the seats help the driver to concentrate on operating his vehicle. The use of a number of comfort items in this classy and functional space allows occupants to enjoy a sense of well-being similar to that found in the first-class cabin of an aircraft. Soft illumination for the center console monitor and door trim creates a serene ambience while generating a high-tech look. The illumination flashes on/off when the drive battery is being charged to create an atmosphere that aesthetically befits a plug-in hybrid. The grouping of the power window, interior door handle and other switches in a single touch panel has reduced the number of individual parts in the interior and contributes to its clean and uncluttered layout.

In terms of environmental performance, an Eco-Drive selector switch on the center console that conserves engine output, transmission and air conditioning power consumption together with an indicator in the instrument monitor that displays Eco-Drive status and effectiveness help the driver to minimize energy consumption. Other environmentally-friendly features include the use of Mitsubishi Motors’ own “Green Plastic” plant-derived resin technology in various items of interior trim throughout the cabin.

Mitsubishi Plug-in Hybrid System
Selection of drive modes delivers smooth and comfortable performance over all kinds of roads
The new Mitsubishi Plug-in Hybrid System that powers the MITSUBISHI Concept PX-MiEV maximizes the strengths of the EV: zero drive-time CO2 emissions*, powerful road performance with the gutsy torque inherent to an electric motor, and very quiet operation. The new system also incorporates a high combustion efficiency 1.6-liter MIVEC gasoline engine that is used either to turn a generator and supply the motors directly with current or charge the car’s lithium-ion drive battery or, at higher vehicle speeds, to augment the motive power supplied by the motors.

The result is a major increase in cruising range. The Mitsubishi Plug-in Hybrid System features Mitsubishi Motors’ new MiEV OS (MiEV Operating System) that constantly monitors the charge and discharge of electrical power depending on driving conditions and the remaining energy in drive battery and selects the optimum drive mode through integrated control of the EV components and the gasoline engine. Minimizing power consumption, the system delivers road performance that is comfortable, safe and reassuring at the same time.

At low to middle vehicle speeds the MITSUBISHI Concept PX-MiEV runs in all-electric mode with the drive battery supplying current to its motor(s). When the remaining energy in the drive battery falls the system switches to series hybrid mode, automatically starting the gasoline engine to turn a generator that supplies the motor(s) with electrical power. At higher vehicle speeds the system switches over to parallel hybrid mode adding the gasoline engine with its higher combustion efficiency at high revolutions to provide more motive power to the wheels. This means that depending on circumstances, at higher vehicle speeds the system can add motive power to the motors, increasing road performance. When decelerating, the system switches over to regenerative mode, using the motors as generators to charge to drive battery. In these ways, the Mitsubishi Plug-in Hybrid System switches between three drive modes depending on driving conditions and remaining energy in the drive battery: all-electric EV mode; on-the-move generating EV mode; and Motor + Engine mode.

The system also incorporates the ECO mode found in the i-MiEV production model that reduces motor output and increases the amount of kinetic energy reclaimed when decelerating to provide low-consumption and environment-friendly performance. In ECO mode the system also controls the operation of the air conditioner compressor to minimize the vehicle’s overall power consumption.

*: CO2 emitted during the generation-to-charging process is excluded.

EV mode
At low to middle vehicle speeds the vehicle operates in all-electric mode with current from the drive battery turning the front motor which rotates the front wheels. When driving on snow, in the rain or in other low surface friction situations where maximum vehicle stability is required, the system automatically switches to 4WD by feeding power to the rear wheel motor as well when sensors detect any wheel slip.

Series hybrid mode
When the remaining energy in the drive battery falls the system automatically switches to series hybrid mode and starts the gasoline engine to power the generator and use the electricity generated to turn the motor. As in EV mode, the system switches to 4WD when circumstances so require.

Parallel hybrid mode
At higher vehicle speeds the gasoline engine, with its high efficiency at high revolutions, supplies additional motive power to assist the front motor. When the driver makes sudden lane changes or other maneuvers requiring maximum vehicle stability the system switches to 4WD by bringing in the rear motor to drive the rear wheels. When overtaking at higher speeds or in other situations requiring faster acceleration the system uses both the front and rear motors and the gasoline engine to supply motive power.

Regenerative mode on deceleration
When the vehicle is slowing or descending a long slope and the driver has his/her foot off the accelerator the system switches to the regenerative mode in which the front and rear motors serve as generators driven by the kinetic energy reclaimed from the drive train, converting it to electricity which is then stored in the drive battery.

Charging mode
As with the i-MiEV production model, the MITSUBISHI Concept PX-MiEV features a 3-way battery charging system that uses either a 100-volt or 200-volt domestic supply or a high power quick-charging station. The system also incorporates a Wireless Charging Program feature that allows the owner to start charging the battery or start the air conditioner at a preset time even when away from the vehicle.

Normal charging:
In normal charging, the driver simply connects the charger cable to a standard domestic outlet and then to the
socket on the vehicle. The charging process starts and stops automatically. An on-board charger converts the
domestic supply voltage to the voltage required to charge the battery.

Quick charging:
For quick-charging when away from home, the driver plugs the vehicle into a quick-charging station provided at shopping centers and other facilities into the quick-charge connector on the vehicle. Charging takes about 30 minutes and stops automatically when the battery reaches 80% of full charge.

Wireless Charging Program Feature:
The system incorporates a Wireless Charging Program feature that allows the owner to start charging the drive battery or start the air conditioner at a preset time even when away from the vehicle using a two-way remote controller.

Charging timer:
The owner can preset the time for charging to start, allowing him/her to make use of times when electricity rates are cheaper (i.e. night time, depending on power company rates).

Preset air conditioning:
The driver can preset the time the air conditioning is activated so that the car interior is at a comfortable temperature before entering the car.

Power supply mode
The MITSUBISHI Concept PX-MiEV also subscribes to the “Smart Grid” concept that calls for maximizing the effective use of electrical power and which is currently attracting attention in the fight to combat global warming. When the vehicle is stationary, the electrical energy stored overnight in the MITSUBISHI Concept PX-MiEV ’s drive battery can be used to power electric home appliances during the day when domestic electricity consumption is highest by connecting them to the charging socket on the car. The battery power can also be used as an emergency power source in the event of a natural disaster and the system will start the engine to generate electricity when the energy remaining in the battery drops. The 100-volt AC auxiliary socket in the rear luggage compartment also allows the drive battery to be used for a variety of non-vehicle uses including powering cooking or lighting equipment and other appliances when camping or engaged in other leisure activities.

S-AWC (Super All Wheel Control)
The MITSUBISHI Concept PX-MiEV uses Mitsubishi Motors’ proprietary S-AWC advanced vehicle handling control system that regulates torque and braking at each wheel individually to deliver on-demand handling and outstanding vehicle stability. S-AWC exercises integrated control over the following system components: ASC (Active Stability Control) and ABS (Anti-lock Brake System); E-4WD (Electric-powered 4WD) which electronically controls front and rear motor output; and E-AYC (Electric-powered Active Yaw Control) which electronically controls rear wheel torque split at the rear wheels.

Like the AYC system on the Lancer Evolution X, when required by driving conditions E-AYC controls traction and vehicle stability by generating a torque difference between the left and right wheels. However, while AYC employs a wet multi-plate clutch arrangement to transfer drive torque between the wheels and generate a torque differential, E-AYC uses a differential motor located between the rear wheel drive axles. The use of a differential motor provides a high-efficiency, high-response system that reduces torque transfer losses and that can reclaim energy.

E-AYC control modes
Controlling understeer:
When the S-AWC system detects that the car is understeering, the E-AYC differential motor increases the speed difference (revolutions) between the inner and outer wheels and transfers torque from the inner wheel to the outer wheel. The resulting change in torque difference generates a split-second reverse wheel rotation, controlling understeer.

Controlling oversteer:
When the S-AWC system detects that the car is oversteering, the E-AYC differential motor reduces the speed difference (revolutions) between the inner and outer wheels and transfers torque from the outer to the inner wheel. The resulting change in torque difference generates a split-second reverse wheel rotation, controlling oversteer. When it operates in this way the rotational speed of the differential motor slows, allowing torque energy to be converted to electrical energy and reclaimed by the battery.

Electronically-controlled air suspension
3 ride heights maximize vehicle stability over poor surfaces and at higher speeds and improve access to the vehicle
At the turn of a switch the driver can select from three ride height modes, allowing him/her to choose the optimumheight for road surface and other driving conditions and thereby maximize vehicle stability and facilitate access to and from the vehicle.

 

 

Auto (normal ride height)
Auto height adjustment maintains the ride height at a fixed level regardless of the number of occupants or amount of luggage carried to deliver a comfortable ride and optimum vehicle stability on the road. At higher vehicle speeds the system automatically lowers the ride height to improve aerodynamic performance and vehicle stability.High
Selecting the High setting raises the ride height of the car and provides additional vehicle clearance over poor road surfaces. As vehicle speed increases ride height is lowered automatically to the Auto height.

Low
When the vehicle is stationary the driver can select the Low setting to lower the ride height and facilitate passenger access to and from the car and also loading and unloading of luggage. If the driver starts off with Low selected, the ride height will automatically be raised to the Auto height as vehicle speed increases.

Comfort / Interior Environment
Proposal for fun and pleasantly comfortable interior space
The MITSUBISHI Concept PX-MiEV provides an interior space that is friendly to both occupants and the environment and that, with special attention to operability and visibility, can satisfy anyone with its comfort and driving pleasure.

cocochi-interior : new technologies package

 

Clean, Stress-free, Safe & Reassuring
Mitsubishi Motors has been introducing in its production cars the cocochi-interior which embraces occupants in a pleasantly comfortable cabin environment developed to a “Clean, Stress-free and Safe & Reassuring” theme. The MITSUBISHI Concept PX-MiEV adds to the cocochi-interior technologies already found in some of its production models a number of new technologies still under development to provide a cabin environment that is as healthy as it is comfortable.Clean
Upholstery deactivates allergens, breaks down VOCs and offensive odor molecules, sterilizes bacteria
The MITSUBISHI Concept PX-MiEV uses seat upholstery that incorporates an antiallergen agent and a visible-light photocatalyst. The application of an antiallergen coating to the upholstery deactivates the allergenic activity of ticks, pollen and other allergens and prevents allergic reactions caused when these agents come into contact with the skin or enter the body. The visible-light photocatalyst is activated simply by visible light even while the vehicle is fitted with UV blocking window glass and is therefore able to promote the action of visible light in actively breaking down and decomposing harmful volatile organic compounds (VOCs) and offensive odor molecules and in sterilizing bacteria.

Cabin heat load reduction
Total vehicle heat management improves AC energy efficiency
To reduce the heat load entering the car from outside, the MITSUBISHI Concept PX-MiEV uses a heat reflecting windshield and infrared blocking glass in the door windows. The body coloring also uses paint with high heat reflective properties. Inside the vehicle, heat insulation of the head lining has been upgraded, the four seats are individually air conditioned and cabin humidity is regulated. The adoption of these heat load reducing technologies allows efficient climate control while reducing power consumption to the absolute minimum in realizing a very comfortable occupant space.

Heat reflecting glass reduces build up of cabin temperature
The windshield uses glass with an external coating of metal oxides and with an organic laminate interlayer. This provides a significant reduction in the amount of heat energy transmitted into the cabin because the radiant heat caused by the rise in the temperature of the glass is lower than for conventional heat absorbing glass. Restricting the rise in cabin temperature reduces power consumption because less use of the air conditioning is required. The heat reflecting glass meets the CARB (California Air Resources Board) Cool Car standards due to be enforced in 2012.

Individually air-conditioned seats
Under each seat is a fan that directs a flow of air to the neck, back and rear of the thighs to effectively enhance occupant comfort. Sending dehumidified air over the human skin directly affects the person’s sense of temperature and allows the air conditioner level to be lowered, thus saving power while achieving optimal occupant comfort. Each seat fan can be individually controlled to suit occupant preference.

Advanced Technologies
Switch and control operability/viewability enhancing technologies

 

Ergonomic design for maximum safety, peace of mind and smooth operation
Mitsubishi Motors continues its research into switch and control operability and viewability along ergonomic lines. The MITSUBISHI Concept PX-MiEV uses a new-generation steering wheel-mounted switch and control layout that offers outstanding usability and viewability. Some audio, navigation, and climate control switches are grouped together on the steering wheel while switch status indicators are located in the instrument cluster where they require very little eye movement to be seen by the driver. With the switches and controls positioned so that the driver can operate them without having to take a hand off the wheel, the new layout provides outstanding operability and viewability for greater safety, peace of mind and comfort.Driver Monitoring System
Linking man and car interactively for better safety, greater peace of mind
Mitsubishi Motors is actively seeking to make its cars safer and less stressful to drive by linking driver and car in an interactive manner. One example of this research is the Driver Monitoring System in which a camera mounted in front of and facing the driver monitors his/her eye movements to determine his/her level of concentration while driving. If the system detects a decrease in their concentration it issues not only audible but visual and vibrational warnings and also emits a distinctive fragrance to alert him/her to the situation.

New Multi-around Monitor
Camera images of vehicle perimeter give driver all-round vision
The Multi-around Monitor superimposes images taken by cameras located at both front end corners, on both sides and at the rear of the vehicle to produce a bird’s eye view of the area surrounding the car. This is displayed on the monitor and allows the driver to check the full vehicle perimeter. In a world-first, the nose-view camera, which covers a field of 190 degrees with a single lens, now uses image processing to provide the ability to detect approaching objects. At intersections and other points where visibility is restricted, the system operates to detect approaching cars and bicycles from either side and warns the driver of their presence by highlighting them on the monitor screen and sounding an audible alert.

Vehicle-infrastructure driving safety support systems DSSS (Level II) and ASV4 information exchange support systems
The MITSUBISHI Concept PX-MiEV is equipped for the Driving Safety Support System (DSSS) currently being promoted by the Japanese National Police Agency. In this advanced vehicle-infrastructure communications system an on-board receiver picks up signals transmitted by roadside optical beacons and the system urges the driver to take extra care when other vehicles or pedestrians have been detected by roadside sensors and cameras at intersections and pedestrian crossings.

Employing a system that uses vehicle-to-vehicle wireless technology to ascertain the position of other vehicles and warn the driver when their proximity so requires, the MITSUBISHI Concept PX-MiEV also supports the Advanced Safety Vehicle 4 (ASV4) project being promoted by the Road Transport Bureau of the Japanese Ministry of Land, Infrastructure, Transport and Tourism. The system boosts the driver’s awareness of an approaching object by displaying images from the nose-view camera as well as a simplified image of the object.

DSRC capability
New intelligent transportation system employs ETC wireless channel
The MITSUBISHI Concept PX-MiEV is fitted with a Dedicated Short Range Communications (DSRC*) system and employs the road-to-vehicle communications capabilities used in Electronic Toll Collection (ETC) to determine the position of the vehicle and whether it is parked or not. This system can be configured to sound an alarm if the vehicle is being or has been stolen. Research is currently ongoing to equip the system for automatic payment of charges for using quick-charging facilities.
*: 5.8 GHz band two-way wireless communication channels specifically designed for automotive use.

Reinforced Crash Safety Body
Steadfast safety technology that provides peace of mind
The MITSUBISHI Concept PX-MiEV uses the same structural modifications for protecting the drive battery system as the i-MiEV production model. Using Mitsubishi Motors’ own RISE (Reinforced Impact Safety Evolution) crash safety body, the drive battery pack and the rest of the high-voltage components are mounted under the floor and inside the body frame. The specially strengthened battery pack is further protected by a special cross member that also improves multidirectional impact protection for reassuring crashworthiness. Safety is also enhanced by a high-voltage circuit breaker which immediately interrupts the drive battery and other high-voltage circuits when a deceleration sensor detects an impact.
