Both Coupe and Roadster versions of Audi's TT 2.0 TDI are now available with quattro all-wheel drive.
The diesel powered 2.0-litre unit will be exclusively mated to a six-speed S tronic twin-clutch transmission. The quattro drive uses an electro-hydraulic multi-plate clutch to distribute the torque to both axles, and in many everyday driving situations it will direct the engine’s power predominantly to the front wheels. Should traction decrease there, the clutch continuously redirects the torque to the rear within a few milliseconds.
When driving at the limit, the quattro system operates in tandem with wheel-selective torque control, an intelligent software feature of the Electronic Stabilisation Control (ESC). Audi says this makes handling 'even more fluid and stable’ with metered brake applications to the wheels when cornering. On low-friction surfaces, the permanent all-wheel drive system even allows controlled drifts.
The TT’s 2.0 TDI has a 184PS output, and 380 Nm of torque for a 0 to 62mph of 6.7 seconds (Coupé) and goes on to clock up a top speed of 145mph. The Roadster accomplishes the sprint in 7.0 seconds and continues to a top speed of 142mph. In the Coupé, the 2.0 TDI quattro S tronic achieves fuel consumption of 54.3mpg, which equates to 137 grams of CO2 per kilometre. For the TT Roadster, the figures are 52.3mpg and 142 g CO2 per kilometre.
The Audi TT 2.0TDI Coupe and Roadster will be available for UK ordering in early 2017, with first customer deliveries in the spring.
