Told me they had, scrubbing many tyres in the process. Dan Prosser @TheDanProsser Exactly that. The wheels on one side rotate forwards, the others backwards. Pointless, but demonstrates how effective all-wheel torque vectoring can be. ] I have never seen a car do a better donut from standstill than this heavily modified, electrified Audi S3 with Formula E motors called the Schaeffler 4ePerformance Concept. Schaeffler, a motorsports company known for engineering vehicles that can be raced backwards almost as quickly as they can drive forwards, has been showing off its latest monster, the 4ePerformance Concept, which is an electrified Audi S3 with four Formula E-sourced motors—they come from the ABT Schaeffler FE01 race car—powering the wheels. Schaeffler claims the car has 880 kW of power, or over 1,180 horsepower, and two batteries couple for a total capacity of 64 kWh ... Uh, it is most certainly NOT pointless. It’s cool as hell. As explained on the company’s website, each of the car’s electric motors is connected to its respective wheel with a “spur gear unit,” and each pair of motors on each axle share a gearbox. This effectively allows for selective torque vectoring of each wheel, which is how you can get the front-left wheel to spin forward while the rear-right wheel spins in reverse. It all makes for as near a perfect donut as is imaginable, and it’s beautiful.

Well, it’s all in how the electric motors are implemented. It packs four electric motors, with one driving each wheel via spur gears. The two electric motors at the front and the two at the rear each share a gearbox housing, creating an electric twin-axle. That allows the left wheels to spin forward while the right wheels to spin backward, making the RS3 spin in a perfect, standstill circle.
