Mazda reveals Mazda2 EV with range-extender Wankel rotary engine

Mazda reveals Mazda2 EV with range-extender Wankel rotary engine It’s long seemed logical that a compact Wankel rotary engine – running at a constant speed – would be a great way of fitting electric cars with a range-extender option. Audi flirted with the idea of fitting the A1 e-tron with a Wankel engine a couple of years ago, but that got shelved. And Mazda – keepers of the Wankel flame – came up with the idea of a Wankel engine bolted in to an EV and powered by hydrogen last year, but it seems to0 have gone nowhere.

What's different about electric cars this time? A column by Kevin A. Wilson

Thirteen years after the General Motors EV1 was rolled out to cheers from advocates of a revolution in the way we power automobiles, those same advocates are out front cheerleading yet another revival of an idea as old as the automobile itself: Run 'em on batteries. Batteries aren't a source of energy. They're just storage units, a convenient means of making power portable.

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.
