Nissan LEAF

It would be easy to paint Nissan as late to the burgeoning U.S. green party, as the company essentially only counts the Altima Hybrid to sell among its alt-fuel offerings – and that sedan utilizes technology borrowed from Toyota, and it's only sold in a few states in small volumes. While that may be the case, Nissan says their near-term prospects are really quite different. While the company has admittedly been cautious in marketing alt-fuel vehicles in North America, they have been hard at work developing electric vehicles – as well as the advanced lithium-ion batteries to support them – since 1992. What's more, officials say they are now singularly well-placed to leapfrog "transitional" powertrain solutions like gas-electric hybrids in favor of genuine zero-emissions vehicles, and they are promising that their first pure-electric car will reach U.S. shores late next year.

That car, the Nissan Leaf shown here, is the reason we find ourselves in the company's brand-new Yokohama headquarters today. Designed as a four-to-five seat, front-drive C-segment hatchback, Nissan says the Leaf is not just for use as a specialty urban runabout, but rather, it was designed as an everyday vehicle – a "real car" whose 160-kilometer+ (100 mile) range meets the needs of 70% of the world's motorists. In the case of U.S. consumers, Nissan says that fully 80% of drivers travel less than 100km per day (62 miles), making the Leaf a solid fit for America's motoring majority, even taking into account power-sapping external factors like hilly terrain, accessory draw, and extreme temperatures.

We were afforded an advance look at the Leaf ahead of the car's unveiling today, and while it was a hands-off affair, we did have the chance to formulate some in-the-metal first impressions and take a deep dive into the car's technology. Click through to the jump to learn all about it.

2011 Mercedes-Benz Viano Vision Pearl Concept

The design concept is takes its inspiration from that of modern sporting yachts, with the theme of travel as an experience. The onboard W-LAN connectivity caters for the needs of modern, mobile individuals. For ther exterior design, Mercedes-Benz has for the first time in the van sector used the paint finish “magno pearl grey”, a matt, pebble-grey colour. The stylistically revised front end of the Viano with its integrated LED daytime running lamps gives the van a more sporty, powerful appearance

The interior of the Viano Vision Pearl is not so much a functional space for passenger transport, but rather a living space. The name Vision Pearl emphasises both the design concept and the repositioning of the Viano: the Viano of the future is the perfect travelling companion, and in this version it conveys a modern, maritime theme.
The Viano Vision Pearl is rounded off by the Bang & Olufsen sound system. Mercedes-Benz has worked together with this world-renowned manufacturer of audio systems since 2009, and integrates the high-end sound systems into passenger cars such as the S-Class. Thanks to the very high output of 1320 watts (the S-Class has 1200 watts) and 18 integrated, specially hand-built loudspeakers, the vehicle occupants are treated to an outstanding listening experience. The Viano Vision Pearl is stylishly discreet where the outside world is concerned: as the loudspeakers are located in their own housings, very little sound volume escapes to the outside.

BMW Z4

Combining classic proportions with modern sportiness, the new BMW Z4 has reached the top of its market segment almost overnight. And now this charismatic roadster is entering a new dimension in driving dynamics, the new BMW Z4 sDrive35is offering an even higher standard of performance ensured both by the modified straight-six power unit with BMW Twin Turbo Technology and High Precision Injection, on the one hand, and by BMW's seven-speed Sport Automatic with double clutch operation and the M Sports Package including the adaptive M Suspension likewise featured as standard, on the other. Appropriate optimisation in engine

technology increases maximum output of the 3.0-litre power unit to 250 kW/340 hp. Peak torque is 450 Newton-metres/332 lb-ft, increasing briefly with the Overboost function to 500 Newton-metres/369 lb-ft. The outstanding power and performance of the BMW Z4 sDrive35is is expressed in particular by the significant increase in pulling power and muscle to be clearly experienced in all situations. In conjunction with seven-speed Sport Automatic featuring double clutch operation, this new top-of-the-range

BMW M3 CRT

The BMW M3 CRT (Carbon Racing Technology) embodies a concentrated blend of state-of-the-art development expertise - inspired directly by motor sport - in the areas of drive system and chassis technology and intelligent lightweight design. It also represents the worldwide debut of a new production process for carbon-fibre reinforced plastic (CFRP) components in the automotive industry. This process allows CFRP to be introduced widely in the construction of the high-performance BMW M3 Saloon-based sports car

created by the BMW M GmbH factory. And that helps it achieve a weight-to-power ratio of 3.5 kilograms per horsepower. A V8 engine with customary M high-revving characteristics and maximum output of 331 kW/450 hp accelerates the BMW M3 CRT from 0 to 100 km/h in just 4.4 seconds.
The BMW M3 CRT will be produced by the BMW M GmbH factory in a limited run of 67 units. Following in the tyre tracks of the BMW M3 GTS - of which 135 examples were produced - this is the second small-series, high-performance M3 off-shoot to be bred for the race track but registered for the road. The exclusive character of the Saloon is emphasised by bespoke lightweight design components manufactured as part of an innovative production process. The bonnet of the BMW M3 CRT and the bucket seats for the driver and front passenger are made from a cellular carbon honeycomb, which is produced in a globally unique process pioneered for the manufacture of body components for the BMW i3 and BMW i8 models.

These new models - due to enter volume production in 2013 and equipped with innovative electric and BMW ActiveHybrid drive system technology - will feature a body consisting entirely of CFRP in the passenger cell area. In a new development, the production process introduced for this purpose enables the cuttings left behind in the construction of the body to be reprocessed. The basic material (made up of carbon fibre thread) can now be woven into CFRP mats of any size before being impregnated with synthetic resin and hardened in a similar way to the material used in the body of the BMW i3 and BMW i8. For the BMW M3 CRT this allows the creation of a bonnet made from two CFRP mouldings encasing an aramid honeycomb structure. This construction imbues the bonnet with the strength of a conventional steel equivalent, but at roughly a quarter of its weight. The weight saving over the aluminium bonnet of the standard BMW M3 Saloon is around 50 per cent.
The material produced through this innovative manufacturing technology is also used for the car's bucket seats. Here, the CFRP layers are wrapped around a recycled-paper honeycomb, with a carbon layer made using conventional production technology added to visible areas. CFRP is also used to make both the rear spoiler of the BMW M3 CRT and an air-channelling element integrated into its front apron.
This innovative manufacturing process opens up considerable potential for increased use of CFRP in series-produced cars as a means of lowering weight. The BMW Group is leading the way in this area of automotive construction, while BMW M GmbH can call on extensive racing expertise when it comes to intelligent lightweight design. The BMW M3 CRT is the latest in a fine tradition of highly exclusive high-performance sports cars optimised with the help of lightweight design. This lineage stretches back to the BMW 3.0 CSL of the 1970s and reached another high point in 2002 with the BMW M3 CSL. BMW M GmbH also broke new ground with the use of CFRP in series-produced vehicles; like the BMW M6 produced up to 2010, the current BMW M3 Coupé comes as standard with a roof made from carbon-fibre reinforced plastic.
Significant weight reduction despite generous standard equipment.
The low-weight construction of the BMW M3 CRT is enhanced by sound-proofing configured specially for the new variant and a sports exhaust system with an extremely lightweight titanium muffler. Also unique to the CRT are the two individual rear seats, which take their cues from the lateral support-enhancing contours of the front seats.
Included in the standard specification of the BMW M3 CRT are the M double-clutch transmission with Drivelogic, Navigation system Professional, BMW Individual High End audio system, a light, exterior mirror and luggage area package, an alarm system and Park Distance Control with sensors at the front and rear of the car. Despite this extremely generous selection of standard kit, its DIN unladen weight of 1,580 kg undercuts that of the standard BMW M3 Saloon by around 45 kg. When you take into account the equipment on board the weight saving is more like 70 kg. Added to which, cleverly reducing the load at the front of the car raises the proportion of the car's weight over the rear axle to 48.4 per cent, which has an extremely positive effect on agility.
High-revving V8 engine with extra power; M DCT Drivelogic.
Under the CFRP bonnet of the BMW M3 CRT lies a variant of the V8 engine developed exclusively for the BMW M3 with further increased displacement, output and maximum torque. The high-revving unit provides the linear power delivery you expect from an M car and a highly responsive performance profile honed by the demands of the race track. Tuned for the BMW M3 GTS, the eight-cylinder engine develops 331 kW/450 hp from its 4,360 cc displacement. Maximum output is reached at 8,300 rpm, and the driver will find peak torque of 440 Newton metres on tap at 3,750 rpm. Helping to give the engine its intoxicating performance is wizardry derived directly from motor sport, including a bedplate crankcase construction in a special aluminium-silicon alloy, individual throttle butterflies, a knock control system with ion current technology and a dynamically-optimised wet sump oil supply.
Transferring the engine's power to the rear wheels is the M double-clutch transmission with Drivelogic developed for the BMW M3. The seven-speed M DCT Drivelogic unit also works according to a principle developed in motor sport, allowing an uninterrupted flow of power through gear changes to deliver extremely dynamic acceleration. Its shift characteristics have been tuned specially for the engine powering the BMW M3 CRT. Shift paddles on the steering wheel allow the driver to change gear manually with optimum ergonomics. And a Launch Control function is on hand to generate maximum acceleration off the start line.
Special chassis construction with race-bred technology.
Expertise from race competition also makes its presence felt in the chassis technology of the BMW M3 CRT. The BMW M3 Saloon's front and rear axle construction has been enhanced by a rigid rear axle subframe and coilover suspension whose dampers are individually adjustable in their compression and rebound. The six-piston, fixed-calliper high-performance brakes of the BMW M3 CRT boast a low-weight compound construction. The vented brake discs measure 378 x 32 millimetres at the front axle and 380 x 28 millimetres at the rear. The new M3 variant also uses Stahlflex brake lines and model-specific comfort brake pads.
The specially tuned DSC (Dynamic Stability Control) system - including ABS and M Dynamic Mode (MDM) - responds to both the greater dynamic potential of the BMW M3 CRT and its optimised axle load distribution. Meanwhile, the 245/35 R 19 front tyres and 265/35 R 19 rears (fitted on 19-inch M light-alloy wheels in Y-spoke design) ensure the engine's acceleration and braking power is transferred to the road with maximum impact. The electronic engine management of the BMW M3 CRT caps its top speed at 290 km/h.
The exclusive Frozen Polar Silver metallic exterior paint shade in combination with Melbourne Red metallic applications and special treatment for the BMW kidney grille also help to set the BMW M3 CRT apart from the standard M3. Inside, the Saloon comes with likewise exclusive door sill strips, door panels and trim strips in aluminium grain structure. Completing the distinctive ambience inside the high-performance Saloon are the Alcantara-covered M steering wheel, which has an M Drive button allowing the driver to call up his preferred set-up instantly, and special Sakhir Orange and Black bi-colour covers for the front and individual rear seats.
