Audi TT uses EA888 family engine

The new Audi TT Sportback five-door concept car that will appear at the Paris Motor Show is powered by a 2-litre TFSI engine developing 400PS and 450Nm of torque.

Audi claims that as a member of the EA888 family, the engine in the four-wheel-drive Quattro concept car uses a comprehensive "package of high-end technologies".

In order to generate the high power, Audi notes that the engine has undergone extensive modifications. The camshaft adjustment on the intake and exhaust sides and the Audi valvelft system, which varies the stroke of the exhaust valve in two stages, ensures good filling of the combustion chambers.

Audi notes that the crankcase consists of "a new high-strength casting alloy" and the crankshaft has enforced iaultrahigh-strength steel.

The redeveloped turbocharger has been configured to provide a boost pressure of 1.8 bar.

The gasoline engine has been teamed with a seven-speed S-Tronic gearbox.
