It may seem an odd time of year to launch a convertible, but Audi has just released details of the new TT Roadster, with first UK deliveries set for early in 2007.

There are no surprises in the new Roadster's styling, with the same evolutionary details as the new TT coupé, which is no bad thing. The new TT's sharper rear end perhaps suits the loss of the roof better than the previous open-top version, though the roll-hoops appear disproportionately large.

The new TT Roadster range is made up of two models at launch, sharing the mechanicals with the coupé. Entry-level models are powered by the now familiar 2-litre turbocharged T-FSI unit with its 197bhp channelled through the front wheels. The other alternative is a 3.2-litre V6 with 247bhp and quattro four-wheel drive. A six-speed manual is standard with the S tronic twin-clutch automatic (Audi's new name for DSG) an extra cost option.

Although the new magnetic ride system (an advanced adaptive damping technology) is also optional, typical equipment is generally quite good on the new Roadster. An electrically-operated roof is standard and even the T-FSI model has sports seats trimmed in leather and Alcantara (the V6 has full leather). The sporty flat-bottomed steering wheel is also standard, as is a Driver's Information System. Buyers of the V6 get a few extra bits of kit, including heated seats, bigger brakes and 18-inch 10-spoke alloys (where the T-FSI model makes do with 17-inch rims).

Audi has ignored the folding hard-top trend for its second-generation TT Roadster, instead citing savings in weight as the main reason for sticking with a cloth roof. Not resting on the success of the first TT Roadster, Audi has completely redesigned the roof to make it more space efficient and practical. There is no need to manually attach or detach the roof from the windscreen for a start and it folds away in an impressive 12 seconds. Just as useful is the ability to raise or lower the roof at speeds up to 30mph. The front section of the roof is rigid and it stacks on top of the cloth portion when stowed to eliminate the need for a cover. UK TT Roadsters also come with a powered mesh wind deflector as standard.

The T-FSI model will cost £26,915 on-the-road with the V6 version priced at £31,535. The models and the prices seem to slip neatly between the BMW Z4 options. Watch the Audi Road Tests page for our review early next year.
