Audi unveiled today at Worthersee Tuning Festival the new TT Ultra sport Quattro Concept. The concept car is better described thanks to an official video, staring Andre Lotterer Audi test pilot.

The showcar combines a lean 1,111 kilograms (2,449.34 lb) total weight with a 2.0 TFSI engine, whose 228 kW (310 hp) and 400 Nm effortlessly propel the coupe. 

From a standstill the TT ultra quattro concept takes 4.2 seconds to 100 km/h (62.14 mph). Its power-to-weight ratio of 3.6 kg/hp is on a par with thoroughbred super sports cars. And it is also worthwhile looking at the detail, not least because the concept car pays homage to automotive lightweight construction.

Even the current series-production car with a body weight of just 206 kilograms (454.15 lb) plus 98 kilograms (216.05 lb) for the detachable body parts is testimony to the outstanding lightweight construction expertise of Audi. 

The engineers from Ingolstadt and Neckarsulm concertedly fine-tuned the Audi Space Frame (ASF) in the current TT generation to come up with the body for the Wörthersee showcar, shedding another 43 kilograms (94.80 lb) from the body structure. Together with the optimized detachable body parts, the result is a weight saving of 100 kilograms (220.46 lb).
