Audi Shows TT-Based Ultra Quattro Concept Ahead Of Wörthersee

The Wörthersee show is a big deal in the Volkswagen/Audi world. It’s so big, in fact, that VW/Audi make a point of bringing along cool, out-of-this-world concept cars to the show every year. The festival has seen the debut of a spate of GTI concepts, including the epic, Bentley-powered GTI W12-650. Audi showed a few concepts last year, with the highlight being the RS Q3.

This year, the premium German brand will be showing a heavily modified TT, first covered by the quattrophiles at Fourtitude. Called the TT ultra quattro Concept, it’s meant to be the most aggressive blend of power and curb weight. It tips the scales at a scant 2449 pounds, making it 857 pounds lighter than the 3306-pound TT RS.

Engineers trimmed a hefty amount of weight from the chassis and frame, while opting for carbon-fiber reinforced polymers for certain sections of the body. Magnesium also played a large role.

Lower curb weight aside, the TT ultra quattro Concept’s 2.0-liter, turbocharged four-cylinder can’t hope to outgun the 2.5 in the TT RS. The concept develops 310 horsepower and 295 pound-feet of torque to the RS’s 360 ponies and 343 pound-feet. All told, the two cars seem evenly matched in a straight-line run. Audi claims the lightweight concept car can snap to 62 miles per hour in just 4.2 seconds, while the TT RS will get there in 4.1.

There’s much more to be found at Fourtitude, including a full rundown of the production models Audi will be brining to this year’s show. The festival runs from May 8 to May 11 in the town of Reifnitz, on the shores of Wörthersee.
