Does Porsche have a flywheel?
However, Porsche eventually licensed the concept from Williams Hybrid Power and set about adapting it to endurance racing in the 911 GT3 R Hybrid. Audi, too, had a go with a flywheel in its all-conquering R18 e-tron Quattro diesel-electric prototype.
What car has a flywheel hybrid system?
Williams set up a spin-off company, Williams Hybrid Power, to develop and refine the flywheel hybrid. In , it partnered with Porsche Motorsport to build the 911 GT3 R Hybrid. Porsche Audi then used the flywheel hybrid system to good effect in its R18 e-tron Quattro. This car would win Le Mans three times in a row.
Why is a Porsche flywheel more durable than a lithium-ion battery?
Porsche viewed flywheel storage as more durable than lithium-ion batteries in the extreme power charge/discharge cycles of racing. Unlike a battery, the flywheel motor was capable of being fully charged (accelerated to its maximum speed) and discharged (decelerated to a near stop) multiple times a minute without adverse effects.
How much power does a Porsche flywheel have?
The flywheel motor in Porsche's racer had a capacity of 0.2kWh. It could deliver 163hp (122kW) for up to six seconds, offering boost for acceleration—out of corners or for passing, depending on how/when the driver decided to apply the extra power via a steering wheel-mounted button.
How does a Porsche flywheel motor work?
Mounted in a carbon fiber box where the passenger seat would be in a road-going 911, the flywheel motor received power from, and sent power to, an 80hp (60kW) electric motor/generator at each front wheel. The configuration allowed Porsche to incorporate torque vectoring to improve handling/traction when accelerating from corner apex out.
Did Audi use a flywheel hybrid system?
Audi then used the flywheel hybrid system to good effect in its R18 e-tron Quattro. This car would win Le Mans three times in a row. An illustration of the Audi R18 e-tron Quattro hybrid system. However, Porsche eventually licensed the concept from Williams Hybrid Power and set about adapting it to endurance racing in the 911 GT3 R Hybrid.
