Audi TT ultra quattro concept
At Wörthersee 2013 in Germany, Audi will unveil the TT ultra quattro concept – which combines minimal weight and maximum sportiness.
In addition to the legendary Sport quattro S1, the latest RS models and thoroughbred race cars including the Audi R18 e-tron quattro, which was the first hybrid car to win the 24 Hours of Le Mans last year, will also be part of the action.
The Audi TT ultra quattro concept show car combines a lean 1111 kg total weight with a 2.0 TFSI engine, which effortlessly propels the coupé from a standstill to 100 km/h in just 4.2 seconds.
Its power-to-weight ratio of 205 kW-per-tonne is on a par with thoroughbred super sports cars.
Even the current seriesproduction car, with a body weight of just 206 kg plus 98 kg for the detachable body parts, is testimony to the outstanding lightweight construction expertise of Audi.
The engineers from Ingolstadt and Neckarsulm fine-tuned the Audi Space Frame in the current TT generation to come up with the body for the Wörthersee show car, shedding another 43 kg from the body structure. Together with optimised detachable body parts, the result is a weight saving of 100 kg.
The Audi TT ultra quattro concept uses carbon-fibre reinforced polymer (CFRP) throughout the rear end, the centre tunnel, in the B-pillars and in the roof. Magnesium components in the floor and used as hinge reinforcement reduce weight even further.
The combination of lightness and sportiness is also reflected in the looks.
Compared with the seriesproduction model, the Audi designers have honed the show car’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 aluminium, while the wing, as a functional element, is made of carbon.
The Audi show car demonstrates the technical possibilities of an intelligent mix of materials.
