Audi has unveiled the Audi TT ultra quattro concept which combines minimal weight and maximum sportiness at Worthersee tour in Austria this week. The concept car is based on the Audi TT S quattro.
Together with the optimized detachable body parts, use of carbon fiber reinforced polymer (CFRP) and Magnesium componenets, the result is the impressive weight loss of about 300 kg. The combination of lightness and sportiness is also reflected in the looks.
The Audi TT Ultra Quattro Concept is painted in the special color crystal white. The CFRP used on the exterior adds a striking touch on the hood, the roof, the sides and the trunk. In the interior the same material also adorns the door trim, the center console and the cross bracing that replaces the rear seat bench. The developers have also fitted the bucket seats from the R8 GT to the concept study.
The TT Ultra Quattro Concept car is powered by a four cylinder, 2.0 liter TFSI engine producing 310 HP and 295 lb-ft of torque. With a power to weight ratio of 3.6 kg/HP, the sportscar is able to reach 100 km/h from a standstill in only 4.2 seconds and is capable of reaching a top speed of 280 km/h.
The combination of lightness and sportiness is also reflected in the looks. Compared with the series production model, the Audi designers have substantially honed the showcar’s contours even further. With its large spoilers, the TT ultra quattro concept proudly displays its motorsport genes. The base of the rear wing is manufactured as a supporting component from milled aluminum, while the wing, as a functional element, is made of visible carbon.
To reverse the weight spiral, the Audi ultra lightweight construction concept is applied to all elements in the automobile. The developers have further optimized each component. The front brakes feature ceramic discs with an aluminum fixed caliper, the exhaust system made out of titanium ends in a single central tailpipe. The wheels also reduce weight by 20 kilograms. Spokes made out of high-strength aluminum are bolted directly to the CFRP wheel.
