Here’s the new trailer from Porsche featuring its 2012 911 (991) Carrera model. The Carrera is powered by a new 3.4L unit, developing 350 hp. With PDK the 0-62 mph time is 4.6 seconds – 0.1 quicker than the 997. If you specify the optional Sport Chrono Pack, a press of the Sport Plus button reduces that time to 4.4 s.
