GM envisions future city car with EN-V concepts

The city car of the future will seat two people, run on electric power and communicate with other vehicles to reach a destination faster while automatically avoiding traffic tie-ups and crashes. General Motors, working with electric-scooter maker Segway, has developed three concepts tailored toward that vision of future transportation. The Electric Networked Vehicle, or EN-V, concepts go on display May 1 at the World Expo in Shanghai.

Chrysler to build smaller version of Pentastar V6

The Chrysler Group plans to produce a smaller version of its 3.6-liter Pentastar V6 engine, likely at a plant in suburban Detroit, according to a union official and a source familiar with the project. The new 3.2-liter Pentastar V6 is set to debut in the replacement for the Jeep Liberty, the union official said. Chrysler-Fiat CEO Sergio Marchionne has said the Liberty successor will be introduced in January at the 2013 Detroit auto show.

Porsche Panamera S E-Hybrid does 62mpg in the hands of motoring journalists

The Porsche Panamera S E-Hybrid – a Panamera with a plug-in hybrid powertrain – arrives last month, along with a 2013 facelift for the Panamera range , complete with claims from Porsche that it could do 91mpg. That was never going to happen in the real world, but Porsche has followed up its official economy figures with a degree of proof that the Panamera E-Hybrid can actually achieve very impressive economy numbers in the real world, and in the hands of motoring journalists – a group not renowned for their light touch on the throttle. At a press event in Hockenheim, Porsche let car journalists loose on the Panamera E-Hybrid for a total of 42 drives over a total distance of 750 miles and returned an average of 62mpg.
