Design Review: Audi Nuvolari quattro concept

Hot on the heels of the Pikes Peak study at Detroit in January, Audi today unveiled the Nuvolari quattro four-wheel drive concept vehicle at the Geneva Motor Show. In contrast to the Pikes Peak crossover SUV concept, with the Nuvolari, Audi's designers have created a classic, high-powered 2+2 GT coupe.   It's certainly powerful: a 5.0-litre V10 biturbo with FSI direct fuel injection with 600ps and a 0-100km/h time of 4.1 seconds means it's the most powerful roadgoing Audi engine ever developed.

2015 Chevrolet Corvette Z06 details leak, and it's going to have 620 hp and 650 lb-ft of torque

We won't get a complete look at the specs of the 2015 Chevrolet Corvette Z06 until it makes its official debut at the upcoming Detroit auto show, but a web coding blooper means we get a sneak peak at some of its vital stats before the reveal. Specifically, it's set to get 620 hp and 650 lb-ft of torque -- a big boost over the 450 hp and 450 lb-ft of torque the base 'Vette enjoys. How did this happen?

The next McLaren supercar will be called the 650S

We've known that McLaren has a pair of additional models in the works, including a Porsche 911-fighting, 12C-based sports car known only as the P13 and another car positioned between the 12C and the P1. Previously, we'd heard the code name “P15” tossed around in reference to that latter car, but McLaren has officially christened it the 650S ahead of its world debut at the upcoming Geneva motor show. According to the automaker, the 650S “takes learnings from both the 12C as well as the sell-out McLaren P1 [ed note: there has to be a better way to say that] and will be positioned between the two on McLaren Automotive's supercar grid.“ We liked the 12C, and we really, really liked the P1.
