Geneva 10' Preview: Porsche 911 GT3 R Hybrid Ditches Batteries for a Flywheel

Porsche is set to debut the 911 GT3 R Hybrid at the Geneva Motor Show next month. But before you think this 911 hybrid is set up like the popular Prius, think again. Porsche has developed a flywheel system that is unlike the conventional battery-based electric systems that other hybrids use. The flywheel gathers kinetic energy during braking to supply power to two electric motors that are connected to the front wheels.

The flywheel can spin up to 40,000 rpm and is mounted where the passenger seat normally would be. The electric motors provide a burst of 161 horsepower to the front wheels, while the 480-hp 4.0-liter flat six-cylinder powers the rear wheels. The electric motors are engaged by pressing a button on the steering wheel. Porsche claims that the system provides better acceleration out of corners and during overtaking.

In addition to being unveiled next month in Geneva, the 911 GT3 R Hybrid will also be at the Nürburgring 24 Hours on May 15.
