You could ask whether the sports car is still relevant. It would be a good question, but you might as well ask the same of dreams.
The answer to both questions lies in the future or, to be more precise, in the future of the sports car. In the 911, the future is already here. The highly efficient, state-of-the-art engines make a considerable contribution to the comparatively low fuel consumption, but their sound is still unmistakably Porsche.
The 911 engines are also unmistakably sporty thanks to the SPORT button fitted as standard. At the push of a button, the engine becomes tuned for a sharper response and engine dynamics that are even more direct.
The 3.4-litre engine of the 911 Carrera models demonstrates, therefore, that performance and efficiency need not be mutually exclusive. Rather, the downsized engine capacity and increased maximum torque are the intelligent basis by which power output can be increased in an environmentally acceptable and sustainable way. Fuel consumption and CO2 emissions have been reduced by up to 16% compared with the previous model.
In their search for improved efficiency, our engineers analysed an extensive series of engine components. Answers were found, including rapid heating of the engine and gearbox to normal operating temperature after an engine start by the thermal management system, improved air induction and extremely effective direct fuel injection (DFI).
The same principle applies to the 3.8-litre engine in the 911 Carrera S models. There has been no change in displacement since the previous model, but power output has been increased while fuel consumption has been reduced by up to 15%.
Weight is critical to efficiency. This is why the engines have a light-alloy construction, making them lightweight and yet structurally rigid. The result is comparatively low fuel consumption and a long service life.
The engine is the intelligent core of our identity. What else could the ‘Dr. Ing. ’ in our company name possibly stand for?
The 911 Carrera base models are equipped with a 3.4-litre boxer engine with direct fuel injection (DFI) and VarioCam Plus. It develops 257 kW (350 hp) at 7,400 rpm and the maximum torque is 390 Nm at 5,600 rpm.
For the 911 Carrera with 7-speed manual gearbox, this means acceleration from 0 to 100 km/h in 4.8 seconds and a top speed of 289 km/h. The new 911 Carrera 4 accelerates to 100 km/h in 4.9 seconds and has a top speed of 285 km/h.
The 911 Carrera S models are powered by a 3.8-litre boxer engine with direct fuel injection (DFI) and VarioCam Plus. It produces 294 kW (400 hp) at 7,400 rpm and the maximum torque of 440 Nm is achieved at 5,600 rpm.
With optional Porsche Doppelkupplung (PDK), the 911 Carrera S accelerates from 0 to 100 km/h in 4.3 seconds and achieves a top speed of 302 km/h. The new Carrera 4S completes the 0 to 100 km/h sprint in 4.3 seconds and boasts a top speed of 297 km/h.
The EMS SDI 9.1 engine management system ensures optimum engine performance at all times. It controls, for example, the position of the electronic throttle valve (ETC) – a prerequisite for compatibility with the Porsche Stability Management (PSM), which comes as standard. It also regulates all engine-related functions to achieve optimum fuel consumption, emissions and power output whatever the driving style.
Another function is the cylinder-specific knock control. Since the cylinders never all work under exactly the same conditions, the knock control function monitors each one separately. The ignition point is shifted individually, as and when necessary, to protect the cylinders and pistons at high engine speeds.
For compliance with EU standards, the on-board diagnostics detect any faults and defects that may occur in the exhaust and fuel systems and then notify the driver immediately. This also prevents increased pollutant emissions and unnecessary fuel consumption.
