Carrera 4S

For 2009, engine power is distributed to all four wheels via the same electronically controlled Porsche Traction Management system found previously only on the Porsche Turbo. The electronic controls respond to driving conditions even more instantaneously than the previously used hydraulically activated all-wheel drive system. The Carrera 4S model, with a 3.8-litre engine developing 355 bhp, can go from 0 to 60 mph in 4.5 seconds and has a top speed of 185 mph.
