At Porsche, reducing fuel consumption is part and parcel of performance. It goes without saying, therefore, that efficiency technologies are standard features on the 911 Targa 4 models and form an integral part of the vehicle concept.
Whenever the car comes to a stop, the Auto Start Stop function automatically switches off the engine – and restarts it swiftly and smoothly as soon as you operate the clutch or, on models with Porsche Doppelkupplung (PDK), as soon as you release the brake.
The thermal management system regulates the temperature in the engine and gearbox through the intelligent manipulation of heat flow. The resulting improvement in combustion efficiency has a beneficial effect on fuel consumption.
A further fuel-saving feature is electrical system recuperation. This function ensures that the battery is recharged predominantly by the alternator under braking conditions.
