As the 2015 Wörthersee Treffen tour approaches, another concept from the Volkswagen Group emerges and this one packs a 441kW punch.

Audi has taken its TT sports car, added inspiration from the Audi 90 IMSA GTO of the late 1980s and an electric bi-turbo setup to create the TT Clubsport Turbo concept.

The electric bi-turbo is a first for Audi, and plays no small part in boosting the output of the 2.5 litre five-cylinder engine to 441kW and 650Nm - the latter available from 3000-7000 RPM.

That means an output of 176kW/260Nm per litre, helping the TT Clubsport hit 100km/h from rest in just 3.6 seconds, on its way to a top speed of 310km/h.

Most of the action happens in the first 2.5 seconds, during which time the TT will have covered 16 metres. Audi says that’s six metres further than a comparable car - or one-and-a-half car lengths.

The bi-turbo uses an electrically-powered compressor to boost charging pressure and effectively eliminate turbo-lag. The compressor can also keep the turbo circulating when available exhaust gasses are too low.

Audi has added a heavy-duty radiator and a new exhaust system with a racing muffler to minimise back-pressure and provide an “unmistakable, throaty sound".

A 48-volt electrical system supplies energy to the turbocharger compressor via a lithium-ion battery in the boot, and a converter that scales the power down to 12 volts for use with the regular electrical system.

Despite the extra kit (and battery), the TT is still on the happy side of 1.5 tonnes with an un-laden weight of 1396kg, and power still reaches the road via a six-speed manual transmission and Audi’s quattro all-wheel-drive system.

Audi has also upgraded the suspension with adjustable coilovers, and added carbon-fibre ceramic brake rotors to all four wheels (370mm up front) which are housed behind the 20-inch alloy wheels.

The electric bi-turbo and 48-volt storage systems aren’t just one-offs for Wörthersee. Audi says we can expect to see the technology in road-going models soon, with the diesel version in particular “close to production-ready”.

The 2015 Audi TT Clubsport Turbo will join fellow Volkswagen Group concepts in the form of the Skoda FUNstar Fabia pickup and the Volkswagen Golf GTI Clubsport at this year’s Wörthersee.
