2012 Porsche 911 Makes North American Debut: 2011 Los Angeles Auto Show

The long awaited 991-chassis Porsche 911 made its North American debut at the 2011 Los Angeles Auto Show, packing more power, less weight and a longer wheelbase.

The base Carrera comes with a 3.4-liter flat-6 engine with 350-hp, good for 4.4 second 0-60 mph time (4.2 seconds with the Sport Chrono Package). Carrera S models get a 3.8-liter version of the same motor with 400-hp, taking 4.1 seconds to hit 60 mph (3.9 with the Sport Chrono Package and PDK gearbox).

The new 991 is 100 lbs lighter, while a 7-speed manual gearbox (the first ever on a production car) helps improve fuel efficiency. A Carrera will set you back $82,100 for a base model, with Carrera S models priced starting at $96,400.
