Audi TT Clubsport turbo concept Worthersee 2015Audi will showcase a radical 600hp TT Clubsport turbo concept at the Worthersee tuner festival this week – and says the 192mph supercar-fast TT packs electric biturbo tech is “close to production readiness”.

The super-fast TT, which can accelerate from 0-62mph in just 3.6 seconds, has an electrically-driven turbo that responds far faster than normal turbos. It can also supply power for much longer, and can generate much higher turbo boost.

It’s powered by a dedicated 48-volt electrical system, powered by a lithium ion battery in the boot.

Audi says the result is 2.5-litre five-cylinder engine that “builds up its tremendous power without any perfectible delay”.

In a race against a TT with a similarly radical 600hp 2.5-litre engine but no electric biturbo, the TT Clubsport turbo “effortlessly pulls away”.

The effect is particularly pronounced off the line. Because turbo boost is there right away, Audi says the TT Clubsport turbo can cover 16 metres in 2.5 seconds – six metres (or one and a half car lengths) more than a regular car.

Such acceleration is achieved using a regular six-speed manual gearbox too (presumably Audi’s automatics and DSGs can’t handle the power of this mighty motor). How fast would it be with the fast-shifting DSG then..?

Prodigious torque of 479lb ft spread from between 3,000-7,000rpm also helps the car’s response. Audi is the first car maker in the world to pack an electric turbocharger into a direct-injection fuel injected petrol car – surely it’s not far off production?

The TT Clubsport turbo concept is a full 140mm wider than a regular TT, thanks to radical front and rear wings that are open to improve airflow and brake cooling. There’s a massive manually-adjustable rear wing taken from Audi Sport TT Cup racers and, like various other aero parts, is made from carbon fibre reinforced polymer.

There are 20-inch alloys too, which, like the rest of the car, have been styled to reference Audi’s monster 90 IMSA GTO race cars of the 1980s. quattro all-wheel drive, adjustible coilover suspension and side-exit exhausts complete the race car credentials.

Inside, the interior has been fully stripped out and encased within an ultra high strength titanium cage. Weight savings are achieved by extensive use of CFRP and even the door pulls have been minimised down to mere grips.

The Audi TT Clubsport turbo concept will be the star of the brand’s Wortherseee 2015 show stand: it’s an event held in Austria dedicated to Volkswagen Group enthusiasts – come back to Motoring Research later in the week for more from Worthersee 2015.
