Audi TT 2.0 TDI quattro: 53.3mpg

After tantalising us with the R8 diesel, Audi is now giving us a diesel TT for the first time. The new 140mph Audi TT 2.0 TDI quattro delivers 53.3mpg combined consumption, with emissions of just 140g/km CO2. The engine is also Euro 5 compliant.

The diesel TT will be on display at the 2008 Geneva Motor Show (March 6th to 16th) and you can place an order for Coupe and Roadster body styles in the UK on the day the Show opens. Prices are from £26,350, but delivery won’t be until summer 2008.

Audi’s latest 2.0-litre, four-cylinder TDI with common rail fuel injection, advanced piezo injection technology and new turbocharger, fits transversely into the TT’s engine bay. It delivers 170PS, and 350Nm of torque – more than the 3.2-litre V6 petrol model produces.

The TT 2.0 TDI quattro Coupe with six-speed manual transmission takes just 7.5 seconds to reach 62mph and it can go on to a top speed of 140mph.

The CO2 figure of 140g/km for the Coupé is over 20 per cent less than the 2.0 TFSI petrol model. Improvements in combustion chamber thermodynamics mean the new engine can run on up to 60 per cent recycled exhaust that has been cooled by the radiator, which ensures the 2.0 TDI already complies with proposed Euro 5 emission limits.

The TT TDI Roadster reaches 62mph in 7.7 seconds, has a top speed of 138mph, delivers 51.3mpg combined consumption, and emits 145g/km CO2.

The car also features the lightweight Audi Space Frame aluminium and steel hybrid body shell, which results in a kerb weight of 1,370kg for the TT 2.0 TDI quattro Coupe and 1,415kg for the TT 2.0 TDI quattro Roadster.

The TT 2.0 TDI comes with quattro permanent four-wheel-drive, and the Audi magnetic ride adaptive damping system will be available as an option.

Standard UK specification for the new TT 2.0 TDI quattro includes features such as 17-inch Trapez alloy wheels, leather and Alcantara-upholstered sports seats, electronic climate control and an MP3-compatible 140-watt Audi Concert audio system with single CD drive. The Roadster adds a fully automatic electrically operated soft-top and integrated wind deflector.
