Vehicle Overview
Porsche's flagship 911 comes in more than a dozen variants, including more potent versions of the 911 Turbo and new GT3 models. At the low end, the car competes with the Mercedes-Benz SL-Class and BMW 6 Series; higher-performing trims are in a price range with the Maserati Gran Turismo and Aston Martin V8 Vantage.

New for 2010
All but the high-performance 911 Turbo received new six-cylinder engines for 2009. This year, the all-wheel-drive Turbo coupe and cabriolet get a new 3.8-liter six-cylinder with 500 horsepower, up from 3.6 liters and 480 horsepower. The GT3 returns after a one-year absence in base and GT3 RS form, the latter essentially a street version of Porsche's factory racecar. The GT3's new 3.8-liter horizontally opposed six-cylinder packs 435 hp.

The 911 is offered as a soft-top convertible, metal-roofed coupe or glass-roofed Targa. A rear spoiler deploys at 75 mph to enhance high-speed stability; the 911 Turbo has a fixed spoiler.
