Jeep uncovers the 2012 Grand Cherokee SRT8 packing 465 hp

Following a one-year hiatus, Jeep is returning the fire-breathing Grand Cherokee SRT8 to the lineup for 2012, which made its world debut at the New York Auto Show. Central to the changes is a new 6.4-liter Hemi V8 engine producing 465 hp and 465 lb-ft of torque--a 45-hp and 45-lb-ft improvement over the outgoing 6.1-liter unit. Jeep says the SRT8 is good to hit 60 mph in 4.8 seconds, cover the quarter-mile in the mid-13-second range and reach a top speed of 155 mph.

Video: GM's Clay Dean on the future of urban mobility

Clay Dean is the star of a new Faces of GM video, Anticipating the Driving Experience of the Future. The global design director for GM's Advanced Design Group, whose job also entails exploring future transportation design solutions, talks about the need to avoid short-term thinking on urban mobility, as by 2030 60 percent of the world's population will live in cities. As new challenges start to emerge, such as increasing congestion, Dean believes it is time to start thinking about transportation in a completely different way.

VW Phaeton - the new one coming in 2015

A brand new Volkswagen Phaeton Mk2 will be launched in 2015, based on a new architecture being masterminded by cousins Audi. Dubbed VW631, the new VW Phaeton will be based on MLM Evo (modular longitudinal matrix) which makes provision for a plug-in hybrid option, an aluminium-intensive body structure and a much more advanced and less nose-heavy dynamic layout. Although VW chairman Martin Winterkorn has in the past black-flagged the Avantissimo (A8-based) and the Passat Variant Plus (A6-derived), there is still a lot to be said for a second more practical bodystyle in addition to the four-door notch which is almost compulsory in this segment.
