Audi’s TT Clubsport concept car showcases the company’s new electric biturbo technology that’s close to production ready.

The Clubsport concept has a 2.5-liter 5-cylinder engine with two turbochargers – a conventional exhaust-driven turbo and a new, electric-powered turbo.

Turbochargers are traditionally driven by exhaust gas, which causes a lag in power as the engine revs to produce enough exhaust energy to spin the turbo. The electric-powered turbo spins to maximum rpm quickly to fill the gap left by the conventional turbo. It also allows for the conventional turbo to be maximized for top-end power.

Using this system, the TT Clubsport engine makes 600 horsepower and 479.4 lb-ft of torque, and it makes its peak torque from 3,000 to 7,000 rpm. A six-speed manual transmission helps send power to all four wheels. Audi claims a 0-100 kph (0-62 mph) time of 3.6 seconds and a top speed of 192.6 mph.

Power for the electric turbo in the TT Clubsport concept comes from a 48-volt power supply.

Power for the electric turbo comes from a 48-volt electric system, with a lithium-ion battery pack in the trunk that captures regenerative energy.

To go along with the new powerplant, the TT Clubsport has a coilover suspension, an electric lifting function to protect from high curbs and a torque vectoring system. The body has been widened from the stock TT and has angular fenders that are opened to allow for brake cooling. An adjustable rear wing made of carbon-fiber reinforced polymer comes right from the Audi Sport TT Cup racing series.

Audi will show the TT Clubsport at the Wörthersee Tour from May 13th to 16th.
