(VIDEO) An electric Audi R8 can hide another (F12 - e performance)


Yesterday we discovered a technology demonstrator, the A1 Dual Mode Hybrid, but the Audi Future Lab also revealed another version of the R8 e-tron called e-performance.

The Audi R8 e-tron revealed two years ago holds the record of the Nurburgring for an electric car with 8:09.099 but it now as a twin, the e-performance, also known as the F12.

For the record and the comparison, the Audi R8 e-tron weights 1780kg for 381hp and 820nm at the rear wheels only, a car that accelerates from 0 to 100kph in 4.6secondes and whose maximum speed is limited to 200kph , the 48.6kWh battery provides a 215km range.

The F12 e-performance is a bit slower but lighter with 1650kg, 0 to100kph goes under seven seconds, max speed is limited to 180kph with a range of 200km.

In short, the R8 e-tron is the supercar and the e-performance is the electric sports-car.

But the architecture of the car it the most interesting part...

First it receives two battery packs for a total of 38.9kWh, one in a longitudinal position and the other in transversal position on the rear axle.

Then it has three independent electric motors, one in each rear wheel developing 50kW and 200Nm each with a distribution via a torque vectoring technology, while at the front sits a "simple" motor of 50kW and 150nm making it an electric quattro (e-tron quattro) ... At low speeds only the single engine (synchronous) works, while when some power is needed the two rear motors (asynchronous) come into play.
Real laboratory vehicle, the Audi F12 is a drivetrain study, a matrix suitable for a sedan or a city-car / electric or plug-in hybrid (quoting Audi’s press release...) with a battery in the central tunnel or on the rear axle, an electric motor at the front or two at the rear... That leaves some options!
