"Powered by a 6.2-liter V-8 engine and a hybrid drive system, the 918 Spyder Concept could preview a new supercar from the company. We're not expecting it for another year or two at the earliest, however, as its 9,200-rpm, 500-horsepower output and 78-mpg efficiency are sure to prove difficult to render in production. Performance isn't hampered by the hybrid drive system, however: 3.2 seconds to 62 mph, 198 mph top speed, and a promised Nurburgring Nordschleife lap time of under 7:30--faster than the Carrera GT that preceded it. Electric motors on the front and rear axles contribute 218 horsepower to the mix." - Kurt Starnes

Porsche is calling its new hybrid push *Intelligent Performance*. Here's the official page: http://www.porsche.com/microsi... - Kurt Starnes

This car and hybrid models coming soon from Audi, Mercedes and other makers will make it very difficult for start-ups like Tesla and Fisker. I want the start-ups to succeed, but the amount of money and R&D the majors can pour into these projects is significant. And I can't forget to mention the experience of the old-guard companies. - Kurt Starnes

Not to mention the brand recognition, distribution, product support and marketing capability, - Brian Sullivan

Very good points, Brian. The four you mention are profound. - Kurt Starnes
