This year’s Wörthersee Tour festival plays host to an Audi TT clubsport turbo concept delivering 600PS and 650Nm with the help of an innovative electrically driven biturbo compressor that is close to being production ready. With its stripped-out interior, wider stance and distinctive rear wing this will be the most extreme TT to date.

The Audi TT clubsport turbo has a power-boosted 2.5 TFSI engine with very impressive performance data. From 2,480 cc of displacement, the five-cylinder engine produces 600PS of power and 650Nm (479.4 lb-ft) of torque, the latter from 3,000 to 7,000 rpm. This means that it produces 240PS and 260Nm (191.8 lb-ft) per litre of displacement. Power is transferred via a manual six-speed transmission.

The car completes the standard sprint from 0 to 62 mph in 3.6 seconds, with a top speed of 192 mph.

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