When Audi first launched a diesel version of the TT in the UK, you could only get it with quattro four wheel drive. Since the launch of the Mk 3 version, you have only been able to spec it with front wheel drive, but that’s about to change. Coupé and Roadster versions of the new TT 2.0 TDI quattro will be available for UK ordering in early 2017, with first deliveries in the Spring. Curious timing since most drivers probably notice and appreciate the benefits of four wheel drive in the winter months.
The front-wheel-driven TT 2.0 TDI ultra Coupé and Roadster models will continue to be available with six-speed manual transmission only, and the new 2.0 TDI quattro only comes with a six-speed S tronic twin-clutch transmission. No UK prices have been confirmed yet for the quattro model, but expect it to pay around a £3K premium for the quattro drive and auto ‘box.
The quattro drive uses an electro-hydraulic multi-plate clutch to distribute the torque to both axles. In many everyday driving situations, it will direct the engine’s power predominantly to the front wheels, saving fuel. Should traction decrease there, the clutch continuously redirects the torque to the rear within a few milliseconds.
At the limit, the quattro system operates in tandem with wheel-selective torque control, an intelligent software feature of the Electronic Stabilisation Control (ESC). This makes handling even more fluid and stable thanks to targeted, accurately metered brake applications to the wheels on the inside of the bend. On low-friction surfaces, the permanent all-wheel drive system even allows safe, controlled drifts.
The clutch management is integrated into the Audi drive select dynamic handling system which is a standard feature of all UK specification TT models. This allows the driver to select Comfort, Auto, Dynamic, Efficiency and Individual modes which modify the character of their TT. As well as governing the all-wheel-drive system, Audi drive select influences throttle response, steering assistance and S tronic transmission shift points. It also integrates several optional modules such as the Audi magnetic ride adaptive damper control and the deluxe automatic air conditioning.
The TT’s four-cylinder diesel engine has a power output of 184PS combined with torque of 380 Nm between 1,750 and 3,250 rpm. The TT Coupé 2.0 TDI quattro S tronic accelerates from 0 to 62mph in 6.7 seconds and goes on to clock up a top speed of 145mph. The Roadster accomplishes the standard 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 and emissions of 137 grams of CO2 per kilometre. For the TT Roadster, the figures are 52.3mpg and 142 g CO2 per kilometre.
Audi says that half of its customers worldwide choose their new car with quattro four wheel drive.
