AUDI has one of the biggest choices when it comes to choosing a car and that has been increased with the introduction of the all-wheel-drive quattro versions of the TT 2.0 TDI.

The latest versions of the coupe and roadster versions of the new diesel quattro will become available for UK ordering early next year.

The newcomers will complement the existing front-wheel-driven TT 2.0 TDI ultra models, which will continue alongside them.

Where these are equipped with six-speed manual transmission, the new 2.0 TDI quattro variants use a six-speed S tronic twin-clutch transmission.

Quattro drive uses an electro-hydraulic multi-plate clutch to distribute torque to both axles.

In most 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.

Audi says that on low-friction surfaces the permanent all-wheel drive system even allows safe, controlled drifts.

The four-cylinder diesel engine develops 184bhp combined with torque of 380 Nm giving the TT coupe 2.0 TDI quattro S tronic a 0 to 62mph acceleration of 6.7 seconds and 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 coupe, the 2.0 TDI quattro achieves a claimed fuel consumption of 54.3mpg and for the TT roadster, the figure is 52.3mpg. Emissions are 137 and 142g/km respectively.

Prices are still to be confirmed but are likely to start from around £37,000.
