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.

Infiniti EV put on hold to concentrate on volume sales

An Infiniti EV based on the Nissan LEAF (previewed by the LE Concept above) have been put on hold Nissan’s luxury arm, Infiniti, is on a global push to try and make inroads in to the dominance of Lexus in the luxury Japanese car arena, and has ambitious plans to be selling 500,000 cars a year by 2017. But Infiniti sold only a third of that total in 2012, so any chance of hitting the lofty target of 500k cars in the next five years means they must concentrate on volume cars, not niche cars like a Nissan LEAF based EV. That means the LEAF-based Infiniti LE EV Concept we saw at the New York Auto Show in 2012 will stay as a concept for the foreseeable future as Infiniti boss, Johan de Nysschen, seeks volume cars that will push the brand forward and bring proper sales numbers.

Concept Car of the Week: MG EX-E

The MG EX-E, developed by Austin Rover and unveiled in 1985, is the subject of our Concept Car of the Week. Dubbed "The concept car that's too exciting to keep secret", it was a production-feasible project that would act as a blank canvas for all future Austin Rover creations. Roy Axe, Design Director of Rover, designed the car around the Metro 6R4 and had an aluminum chassis and plastic body.
