The infamous driving dynamics of a 911 just got even more impressive with Porsche revealing the 2013 911 Carrera 4 and 4s with all-wheel drive. Complementary to its racing origin, the new 911s feature a seven-speed dual-clutch, an advanced traction control and an info screen, which shows where the power is distributed to. The range topping Carrera 4S comes with an impressive 3.8.liter engine, which enables the coupe to break the 60 in a scant 3.9 seconds sprint whilst topping out at around 185mph.
