Audi has revealed an interesting concept in the form of the TT ultra quattro which is based on the current-gen TT S quattro. Under the hood it packs the familiar 2.0-liter, four-cylinder TSI turbo engine producing 310 HP (228 kW) and a peak torque of 295 lb-ft (400 Nm). The point of this concept is to significantly lower its curb weight and that’s what Audi’s engineers have done as the vehicle is 300 kg (661 lbs) lighter than the standard model, tipping the scales at a mere 1,111 kg (2,449 lbs). It jumps from 0 to 62 mph (100 km/h) in 4.2 seconds which makes it 1.3 seconds faster than the production model, on its way to a top speed of 174 mph (280 km/h).
The body structure was slimmed by a significant 43 kg (94.8 lbs) and if we take into account the optimized detachable parts, the diet stands at an impressive 100 kg (220 lbs). The Audi TT ultra quattro concept has a CFRP rear end, center tunnel, roof and B-pillars, while magnesium was utilized as hinge reinforcement and also for the floor.
Compact cameras have replaced the conventional exterior mirrors, while inside the cabin it has bucket seats borrowed from the R8 GT which have lowered the car’s weight by 22 kg (48.5 lbs) as these have a FRP chassis. Goodies include electromechanical parking brake, air conditioning and electric windows. Stock brakes have been replaced by ceramic discs, while regular wheels have been ditched in favor of different alloys which are 20 kg (44 lbs) lighter.
