• “Motorsport meets quattro” on the Audi stand
• TT ultra quattro concept – minimal weight for maximum driving pleasure
Reifnitz/Ingolstadt, May 13, 2013 – Audi turns the Wörthersee 2013 into the “Home of quattro”. At the large gathering in Reifnitz (Kärnten), the premium brand unveiled the Audi TT ultra quattro concept – which combines minimal weight and maximum sportiness. A wide range of high-performance cars also gave fans another taste of sportiness. In addition to the legendary Sport quattro S1, the very latest RS models and thoroughbred race cars were also on show. The Audi R18 e-tron quattro, which was the first hybrid car to win the 24 Hours of Le Mans last year, was also be part of the action at the lakeside.
The Audi TT ultra quattro concept showcar combines a lean 1,111 kilograms total weight with a 2.0 TFSI engine, whose 310 hp and 400 Nm effortlessly propel the coupé. From a standstill the TT ultra quattro concept is catapulted in 4.2 seconds to 100 km/h. 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.
The engineers from Ingolstadt and Neckarsulm concertedly fine-tuned the Audi Space Frame (ASF) in the current TT generation and adopted an intelligent mix of materials including carbon-fiber reinforced polymer (CFRP) and Magnesium components according to the motto: the right amount of the right material in the right place. Through optimization of each component, overall, the lightweight construction measures make the concept car 300 kilograms lighter than the comparable sporty series-production model.
The combination of lightness and sportiness is also reflected in the looks. 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.
The concept car 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; their chassis alone, made out of fiberglass-reinforced plastic (FRP), reduce weight by 22 kilograms. A veritable highlight: the exterior mirrors are replaced by compact cameras which transfer the images directly into the digital cockpit.
Thus the Audi TT ultra quattro concept offers the kind of driving experience that automotive fans on the Wörthersee expect from a genuine high-performance model. Like the “Ur-quattro” from 1980 and more than five million series-production vehicles since, this year's showcar is also fitted with the quattro permanent all-wheel drive. With its six speed transmission, the TT ultra quattro concept is 1.3 seconds faster than the series-production model when accelerating from 0 to 100 km/h. The top speed is 280 km/h.
The Audi showcar demonstrates the technical possibilities of an intelligent mix of materials. In this way considerable weight savings can even be achieved on an existing series-production model. Usage of these technologies is conceivable for future small-batch series.
