At the Frankfurt auto show last September, Porsche CEO Michael Macht hinted that the sports car maker may soon be offering a hybrid version of its 911. “Soon” apparently means the Geneva auto show, where Porsche will reveal the 911 GT3 Hybrid.
The Stuttgart, Germany-based automaker will use an unconventional approach to its hybrid sports car. Instead of using batteries to store energy, it will use a flywheel that spins at up to 40,000 RPM under deceleration. The kinetic energy generated from the spinning disc will then power a pair of 60-kilowatt electric motors, mounted to the front wheels. The large assembly will sit within the cabin, where the passenger seat once resided. The two motors will provide 8-second bursts of power, supplementing the 480-hp from the 4.0-liter flat-six and helping the Porsche explode out of turns.
The system’s primary benefit, Porsche says, is in fuel economy gains. Porsche is going to enter its newest creation in the 24-hour Nürburgring endurance race, where better mileage should make a significant impact by requiring fewer pit stops. With the greatest amount of fuel consumption coming from heavy acceleration, the 911 hybrid should be able to manage fuel use much more effectively.
The car was developed by a team of engineers from the Porsche Intelligent Performance program. The new hybrid system is currently in its experimental phase as Porsche fine tunes it, but if all goes well, we hope to see a modified version in a production car in the not-too-distant future.
