Audi TT Ultra Quattro concept strip downs, adds lightness

For the 2013 Worthesee meeting Audi is rolling out a ultra-light version of the Quattro TT with around 300kg stripped out of the car.

A 2-litre turbocharged 4-cylinder powers the TT Ultra Quattro concept, not the 2.5-litre turbo 5-cylinder engine from the TT RS and TT RS Plus. In the Ultra the 2-litre engine churns out 228kW (310hp) and 400Nm of torque. Despite having power that’s between the TT S’ 200kW and the TT RS’ 250kW, it’s almost as quick as the TT RS Plus. The Ultra is able to race from 0 to 100km/h in 4.2 seconds, just shaded by the TT RS Plus’ 4.1-second result. Top speed is reportedly 280km/h.

That car’s excellent performance is due to its light weight; the Ultra tips the scales at 1,111kg. Audi’s engineers stripped 300kg overall from the TT S by reducing the weight of the car’s body structure (down around 42kg), and also using carbon fibre reinforced plastic (CFRP), magnesium and aluminium for various components. To improve the car’s weight balance some parts, such as the lithium-ion starter battery which now lived under the driver’s seat, have been moved to within the wheelbase
