Audi attains considerable weight saving in TT ultra quattro concept to be debuted at Worthersee Show
Posted in Concept Cars
Audi engineers have made smart blend of materials and technology to bring considerable weight saving in its latest TT ultra quattro concept to prepare it for its debut at the upcoming Worthersee show. The new TT 2.0 TFSI Coupe Concept has dropped an incredible 300 kg and gained around 310 PS power upgrade. The show car combines its potent petrol engine with its four-wheel-drive system to hit 0-62 mph in 4.2 seconds and a top speed of over 173 mph while weighing just 1,111 kg. There’s also a 2.0-litre turbo that produces 305 bhp, with modifications to the crankcase, the crankshaft, the balancer shafts, the flywheel, the sump, the bolts and certain ancillary units that further helps to reduce the unit’s weight by 25 kilograms. TT Ultra’s body structure had dropped off another 43 kg with the help of optimised detachable body parts. Besides it, the use of carbon-fibre reinforced polymer (CFRP) in the rear end, centre tunnel, B-pillars and roof has helped to attain an overall 100 kg saving. The front brakes are ceramic with fixed aluminium callipers. There is also a titanium exhaust system with a single tailpipe, and CFRP wheels with aluminium spokes to shave off further 20 kg. The conventional steel in the coil springs in the suspension has been replaced with fiberglass reinforced polymer to further get rid of up sprung masses. The core of the all-new springs consists of long glass fibers twisted together and infused with epoxy resin with additional fibers wrapped around the core at alternating angles. These layers support each other and act in either compression or tension and tend to attain overall 40 per cent weight reduction.
