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.

2011 Ford Shelby GT500 Mustang gets more power, loses gas-guzzler tax

The 2011 version of the Ford Shelby GT500 Mustang carries a supercharged 5.4-liter V8 that weighs less, delivers more power and uses a unique spray-coating process that eliminates the need for cast-iron liners in the aluminum cylinder block. The 550-hp Shelby GT500 also loses something from the previous model--it's gas-guzzler tax. Ford says the new Shelby GT500 will deliver 23 mpg on the highway and 15 mpg in the city.
