A widely held belief about motorsport is that power is the only thing that matters. From experience, we know better. Extra horsepower alone has never been enough to win a single race. Much more important to us are ideas – ideas that inspire more intelligent vehicle concepts and more efficient drive systems. The same applies on the road. It’s about getting the most out of what you’ve got.
The auto start/stop function is standard in the 911 Carrera models.
In cars with the manual gearbox, the engine switches off automatically when, for example, you stop at traffic lights, select neutral and release the clutch pedal. In cars with Porsche Doppelkupplung (PDK), the engine switches off whenever you stop and leave your foot on the brake pedal.
All audio and communication systems remain switched on and the climate control continues to maintain your selected temperature. The only differences you will notice are the silence at the rear and the fuel saving. As soon as you operate the clutch or release the brake, the engine will restart swiftly and smoothly.
The auto start/stop function may remain inactive under particular circumstances, for example: extreme outside temperatures, when the SPORT button is selected or if battery charge is low. It is also possible to deactivate the function manually using a separate button on the centre console.
The thermal management system regulates the temperature in the engine and gearbox through the intelligent manipulation of heat flow.
In this way, the engine and gearbox reach their optimum operating temperature sooner. As a result, fuel consumption is reduced through increased combustion efficiency and lubrication performance.
The 911 Carrera models are also equipped as standard with fuel-saving electrical system recuperation technology. The vehicle battery is recharged by the alternator, predominantly under braking. Under acceleration, on the other hand, the power draw of the alternator is limited to increase the engine output available for driving. The electrical systems are supplied by the electrical energy stored during the recharging process.
