It works like a flywheel. The rotor (4) rotates at up to 40,000 revolutions per minute. If it is braked, additional energy is generated for a short time, which is passed on to the front axle.

Almost everyone had experiences with an electric pasture fence in their childhood: one has never moved faster than after a small electric shock. Porsche is now building on a similar effect with a new type of hybrid drive for the 911 GT3. However, it works completely painless.

A.At Porsche, too, Elektro-Power is now booming. While the Swabians, in lockstep with parent company VW, are converting the next Cayenne to a part-time power supply with batteries and an electric motor in the transmission, they use a flywheel to store energy for the 911 GT3 R Hybrid that was promised at the Geneva Motor Show. The small power plant converts kinetic energy into electrical energy and thus supplies the two 98 hp electric motors on the front axle.

This gives the circuit racing car that decisive kick when overtaking or accelerating out of a curve. However, the electric afterburner is short-lived: while the Cayenne can drive several kilometers on electricity, the GT3 only lasts for six to eight seconds. And the consumption advantage will hardly be measurable either.

For their off-road vehicle, on the other hand, the Swabians are predicting savings potential of 20 percent and thus a consumption of eight liters. The flywheel technology was specially developed for racing and, in a similar manner, was also shortlisted for the Kers system by some Formula 1 teams last year.

The electricity generated during braking is used to accelerate a rotor to up to 40,000 tours per minute via another electric motor, which whizzes in a special drum next to the driver.

If the driver requests electrical assistance, the electric motor, which has been reversed into a generator, brakes the rotor again, producing the juice for the two extra motors on the front axle.

Porsche not only wants to demonstrate the principle at the exhibition stand in Geneva, but also want to test it in tough racing conditions. The prototype is therefore going from Geneva to the Nurburgring, where it will take part in the 24-hour race this year.

Completely different than usual, the Swabians only have a limited ambition: "A victory for the 911 GT3 R Hybrid is not the main focus," says Porsche, dampening expectations.

“Rather, as a technology carrier, it should provide knowledge for the later application of hybrid technology in road sports cars.” So it is quite possible that the 911 will soon have even more momentum. And not just on the Nurburgring.
