Audi TT Ultra Quattro revealed
It is expected to feature a more highly tuned version of Audi’s 2.0-litre TSFI engine, developing 306bhp and 295lb ft of torque. Audi’s previous best from this engine was 268bhp and 258lb ft in the TT S Coupe and Roadster.
To achieve the additional 38bhp and 37lb ft torque boost, the engine will probably be both turbocharged and supercharged, like the 1.4 TSI unit in the Skoda Fabia vRS.
The concept car points towards a replacement for the current TT RS, downsizing from the more powerful 2.5-litre turbocharged engine, which should mean improved fuel economy for the range-topping TT.
Despite having less power than the TT RS, the Ultra Quattro's 0-62mph time is expected to be a tenth quicker at 4.2 seconds, while top speed is identical at 174mph.
The concept car achieves these figures thanks to a claimed 299kg weight saving compared with the TT S, and a 339kg saving compared to the TT RS.
An extreme version of the TT – weighing less than 1000kg – was rumoured to have been developed as a lightweight project last year, with extensive use of aluminium and carbonfibre-reinforced plastic. The Ultra Quattro features similar materials in place of heavier steel parts.
