LSD offers gullwing-door kit for the BMW M3

The BMW M3 is a potent performer right off the showroom floor. Intake, exhaust, plugs, wires--these are things that M3 drivers don't need to worry about. But what if you're looking for some flash to go along with your fast?

The BMW M5 is back!

BMW's M division has gone back to the drawing board with the M5, giving the fifth generation of the iconic four-door a twin-turbocharged 4.4-liter V8 engine—the first time Munich's class-defining performance sedan has gone without a naturally aspirated powerplant since its introduction in 1984. Further changes see it adopt a dual-clutch gearbox as part of a complete driveline rethink that resigns the old model's sequential manual transmission to the history books. Revealed here officially for the first time, the new M5 is planned to make its world debut in concept-car guise at the Shanghai motor show later this month.

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.
