2013 Porsche 911 Carrera 4

In terms of looks, changes to the 2013 Porsche 911 Carrera 4 are subtle. The big difference is the all-wheel drive powertrain that keeps the tires glued to the tarmac while shedding almost 150-pounds. With either a 350 or 400-HP motor, each of the four models: the 4, 4S, Coupe, and Cabriolet, come equipped with a 7-speed manual gearbox or the optional gas-saving PDK automatic. For being a safer and more efficient 911, Porsche did a great job of keeping it real.
