Fastest Audi TT breaks cover

This is the 268bhp Audi TTS, the fastest car in the Audi TT range - for now.

Powered by an overhauled version of the company's 2.0-litre TFSI engine, the TTS Coupe has a 0-62mph time of 5.2sec and a limited top speed of 155mph. Average fuel consumption is 29.3mpg.

The roadster version of the car is only marginally slower, recording a 0-62mph time of 5.6sec, with the same limited top speed of 155mph. It does 28.7mpg on average.

Performance can be enhanced further, however, if the buyer opts for the S tronic dual-clutch semi-automatic gearbox rather than the standard six-speed manual transmission.

This gearbox has six forward gears and two clutches. It can change gear in two-tenths of a second, shaving two-tenths of a second off the 0-62mph time.

There are two settings for the suspension system: standard and sport. When the sport mode is selected, the car's body lowers by 10mm to improve balance and handling.

Agility is further advanced by the use of lightweight aluminium and steel in the car's construction.

Emphasising the TTS's position as the flagship model in the Audi TT range are sports seats, 18-inch aluminium wheels and bi-xenon headlights.

Only European prices have been officially released, but the TTS is expected to cost around 35,000 when it goes on sale in the UK in the second-half of this year.

Before you reach for your chequebook, though, bear in mind that rumours of a TTRS, powered by a 340bhp 3.2-litre V6 engine, just won't go away.
