Porsche 911 GT3 R Hybrid
Grand Touring-class race cars are anything but low tech, but compared to a modern F1 car, anything short of the latest military jets are fairly low tech. So Porsche's adoption of last season's F1 KERS hybrid technology from Williams in the 911 GT3 R Hybrid constitutes a giant leap for GT cars.
The system consists of a 40,000 rpm flywheel that grabs kinetic energy from the drivetrain under deceleration, which is stored in the flywheel's motion until it's needed by the front-mounted electric motors that drive the front wheels. When the driver hits the button, it dumps its energy like a battery or generator into the electric motors, adding up to 161 horsepower for a max of eight seconds.
