Audi TT Clubsport Turbo Concept for Wörthersee 2015

The annual Wörthersee show in Austria is an excuse for the Volkswagen Group to wheel out mad machines, mega powered ultimate versions of existing production cars that will never see the light of day. Still, fantasising can be rather pleasurable, and here’s one for Audi TT fans.

To debut at the 2015 Wörthersee Tour in the Austrian town of Reifnitz, the Audi TT Clubsport Turbo Concept was inspired by the successful Audi 90 IMSA GTO of the late 1980s and packs some interesting tech that might surface in the future.

As hinted by the swollen angular fenders, the Clubsport Turbo is wider than the standard TT by 14 cm. They’re open at both ends, allowing air from the car’s slipstream to flow through and cool the brakes. The coupe’s single-frame grille and large air inlets – which vertical fins form a continuation to the light signature of the Matrix LED headlights – are also optimised for maximum air eating capacity.

The manually adjustable rear wing is an advanced development of the Audi Sport TT Cup. It’s 20 cm wider here, and the side flaps, which feature the four rings, were given a new geometry. The wing, as well as other add-ons, are made from carbon-fibre reinforced polymer (CFRP). 20-inch rims complete the package

Under the hood is a 2.5 litre TFSI engine with 600 hp and 650 Nm of torque, the latter available from 3,000 to 7,000 rpm. The five-cylinder engine is paired to a six-speed manual transmission and power goes to all corners via quattro AWD. The 1,396 kg TT does 0 to 100 km/h in 3.6 seconds, on to a top speed of 310 km/h.

An electrically powered compressor revs up to max rpm rapidly and without any perceptible delay, and it continues to boost charge pressure when too little drive energy is left in the exhaust gas for the conventional turbocharger. This makes it possible to design the conventional turbo for high charge pressures, and consequently for high engine power – the e-turbo assures spontaneous response from low engine speeds.

A dedicated 48-volt electrical sub-system supplies energy to the turbocharger. A compact lithium-ion battery in the boot stores the energy that is generated by recuperation when coasting. A DC/DC converter provides the connection to the 12?volt electrical system.

The Clubsport Turbo’s exhaust system is designed for minimal back-pressure; a side pipe to the ambient air is located immediately after the racing-type muffler. The 2.5 TFSI engine is cooled by a racing-type radiator.

Audi Malaysia launched the latest Audi TT in Malaysia last week. The third-generation coupe is powered by a 2.0 TFSI engine with 230 hp and 370 Nm, good for 0-100 km/h in 5.9 seconds and a top speed of 250 km/h. It is priced at RM284,900 on-the-road with GST, without insurance, with a list of tasty options to consider.
