918 a match for Ferrari and McLaren in corners, says Porsche

Had you forgotten about the third contender in the hybrid supercar wars, given the furious competition betwen Ferrari and McLaren? Porsche’s hybrid 918 Spyder is that third competitor, which mates a 4.6-litre normally aspirated V8 to an 84bhp front-drive electric motor and a 127bhp EV motor helping drive the rear tyres. It costs £768,026, and though Porsche won’t quite admit as much, you can still buy one of the 918 being produced - unlike the sold-out LaFerrari.

Porsche Panamera Sport Turismo Concept

This is the Porsche Panamera Sport Turismo Concept – a Porsche Panamara Shooting Brake Hybrid – headed for a Paris 2012 debut.

The Panamera Sport looks like it’s got some sort of hybrid powertrain, although we have no details yet from Porsche.
