Production version of this 918 "coupe" to bow in 2013

Porsche wowed automotive enthusiasts when it unveiled the 918 Spyder nearly a year ago. Porsche made those who can actually afford the vehicle salivate when it announced that it would actually make a production version of the vehicle.

Today, Porsche revealed its racing variant of the vehicle: the 918 RSR. The 918 RSR takes the best of the 918 Spyder (its sexy shape, albeit in coupe form) and combines it with the flywheel-based hybrid system found in the 911 GT3 R Hybrid.

Like the 918 Spyder on which it's based, the 918 RSR uses a 3.4-liter V8 that develops 563hp at an incredible 10,300rpm. The vehicle also features a 36,000rpm kinetic energy recovery system (KERS) flywheel actuator that stores energy generated during braking. With the touch of a button, the driver can call upon two electric motors (one in each front wheel) that use that stored energy to give a momentary power boost (8 seconds on a full charge) to 767hp.

The electric motor also provide torque vectoring for improved handling and steering response.

According to AutoWeek, Porsche has plans to produce a version of this concept for the racetrack, and a production model of the 918 Coupe (minus KERS) will join the 918 Spyder in 2013.

"The KERS is a single "cell" kinetic energy storage device, with an attached generator that is used to supply electricity to the motors. Not a battery by any definition."

Great!. The best definition of KERS to date. Excellent work. So it says 8 seconds to charge meaning the flywheel is spinning down as it discharges (energy=current) to the electric motors for the acceleration.
