Audi introduced in 2005 a special edition for its compact coupe sports car, the TT Quattro Sport.
It was a celebration for 25 years of quattro all-wheel-drive system.

Audi was not the first car manufacturer to enter the market with an all-wheel-drive vehicle. Subaru and Jensen Interceptor FF did that before them. But Audi was the one who made the all-wheel-drive revolution happened when it won the World Rally Championship with the Audi Quattro. Its victories proved that the system was a better choice than the front-wheel-drive or rear-wheel-drive vehicles. To celebrate the Quattro victories and the introduction of that system on the market, Audi prepared a special version based on the TT. It was named Quattro sport.

The Quattro sport was basically a lighter Audi TT with a two-tone paint job and a more powerful engine. The bodywork was a carry-over from the much powerful TT 3.2-liter V6 version, with flared wheel arches. The 15-spoke 18” light-alloy wheels were specially designed for the limited series model. The roof, the rearview mirrors and the small spoiler on the trunk-lid were painted in black

Inside, the car featured two sport-bucket seats with racing inspiration. The rear seats and the parcel-shelf were removed. The Audi engineers shaved about 50 kg (110 lbs) from the normal vehicle. But they didn’t stop there.

Under the hood, there was the same 1.8-liter bi-turbo engine from its siblings but tuned to deliver 15 hp more. A stiffened suspension and a wider track made the car more planted to the road and faster than its more powerful sibling, the 3.2-liter version.
