The engines, as you would expect, are characterised by six horizontally opposed cylinders. The 3.4-litre engine in the 911 Carrera models produces 257 kW (350 hp) ; in the 911 Carrera S models, the 3.8-litre engine develops 294 kW (400 hp). All variants are equipped with direct fuel injection (DFI) and VarioCam Plus for increased power and comparatively low fuel consumption.

Power is transmitted to the wheels by the 7-speed manual gearbox with the highest gear designed specifically with fuel economy in mind or, optionally, by efficiency-enhanced Porsche Doppelkupplung (PDK), which offers gear changes with no interruption in the flow of power.

On the 911 Carrera all-wheel-drive models, the enhanced Porsche Traction Management (PTM) distributes the power to the wheels according to weather and road conditions. Handling is even more poised, particularly when the car is being driven to its limits. As a result, you are safer not just in the wet and snow, but also when adopting a sporty driving style.

The chassis is also packed with forward-looking technology. Fitted as standard in the 911 Carrera S and 911 Carrera S Cabriolet, Porsche Torque Vectoring (PTV) increases dynamic performance. Available as an option for the S models, Porsche Dynamic Chassis Control (PDCC) improves dynamic performance further still. Dynamic engine mounts, available as an option for all models, provide perceptibly more precise handling – and not just when cornering.

The 911 has a lightweight composite construction in aluminium and steel. Used extensively and in just the right places, lightweight aluminium improves fuel economy and dynamic performance and helps to achieve an excellent weight to power ratio of 4.7 kg/kW (3.5 kg/hp) for the 911 Carrera S, for example.
