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.

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 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.

What type of flywheel does a Porsche GT3 use?

In the GT3 R Hybrid, it was reserved for the flywheel. Porsche In the 911 GT3 R, the flywheel motor used a carbon-fiber composite flywheel with a 16-inch (406mm) diameter.

Does a flywheel store energy?

"But the technology wasn't without challenges. In general, the flywheel does not store much energy, just the braking energy," he says. "A battery is able to achieve highly stable long-term energy storage in a way that a flywheel simply cannot match.

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 2010, 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.
