    Ferrari Hybrid Patents Revealed, Two Motor System

    "Ferrari hybrid" is right up there with "Porsche diesel" and "Bentley SUV" as far as oxymorons go. Even so, Porsche has been producing diesels for several years now, soon to hit the U.S, and Bentley showed an SUV concept at the 2012 Geneva Motor Show, so maybe it isn't that unusual after all...

  • Stefan Jacoby, Volvo Cars CEO, at Volvo "Innovations Toward Zero" seminar, June 2011

    Volvo likes to think of itself as a conscientious car company. "Why are we different?" asked Stefan Jacoby, Volvo's German CEO. "We are Swedish; we come from a human-centric company. We do things because they have a purpose for people." Safety, yes, but also green Those things used to revolve around safety, and Volvo still nurtures its safe reputation, adding each year to its hundreds of patents for technology to make cars safer. The company's official goal is that no one will be killed or injured in a Volvo car by 2020. But increasingly the purpose must also be producing greener cars, which...

    World's Fastest (Or 2nd-Fastest?) Hybrid: Porsche 918 RSR

    Possibly the most rapturously received vehicle at last week's Detroit Auto Show was the Porsche 918 RSR coupe, a hybrid race car that isn't even street-legal. And it's about as far from the quintessential Toyota Prius hybrid as you could get. It doesn't use a battery pack at all, in fact, but the...

    What's it like driving the Porsche 911 GT3 R Hybrid, the world's fastest hybrid vehicle? Ask driver Patrick Long, and he'll tell you he's "still pretty charged up (forgive the pun)" after returning to the States following two weeks of testing the car on the Lausitzring circuit outside Berlin. We had a chance to chat with Long next to one of the world's only two 911 GT3 R Hybrid models,  incongruously parked outside a swanky restaurant in midtown Manhattan. He was there to announce that the groundbreaking hybrid would make its first appearance in U.S. competition in the Petit Le Mans race...
