Audi now offers the TT 2.0 TDI in all-wheel-drive drive version, with power transmitted by the S tronic six-speed dual-clutch transmission. 

Using an electro-hydraulic multi-plate clutch, the quatro drive distributes torque to both axles, chanelling engine's power to the front wheels. In case traction decreases, the clutch averts direction from torque to rear in only a few milliseconds.

As it is also integrated into the optional Audi drive select dynamic handling system, the clutch management enables the driver to specify TT in the modes comfort, auto, dynamic, efficiency and individual.

At a certain extent, the quattro drive runs with an intelligent software feature of the Electronic Stabilization Control (ESC), which allows better handling. Audi claims that even on low-friction surfaces, the permanent all-wheel drive system allows safe and controlled drifts.

Optional modules include the brand's magnetic ride adaptive damper control and the deluxe automatic air conditioning.Audi brings quattro all-wheel-drive to TT 2.0 TDI

Audi said that with the help of the quattro drive, the TT Coupe can sprint from 0 - 100 km/h in 6.7 seconds before hitting a top speed of 234 km/h. The TDI motor produces 184 PS and 380 Nm of torque at 1750 to 3250 rpm.

With this new offer, the Audi TT is now available in seven engines/transmission variants. The manufacturer also said that the all-wheel-drive version with S tronic can now be ordered, to be delivered by early 2017.
