The new TT roadster has a folding fabric roof that will raise or lower at up to 31mph in just 10 seconds. Measures have been taken to ensure that removing the roof doesn’t also remove the fun - moulded aluminium struts have been added around the base of the A-pillars and beneath the body.
Audi's TT coupé was already fairly lightweight and rigid, thanks to heavy use of aluminium and hot-formed steel. The modifications involved in turning it into a convertible have added a respectably low 90kg. Audi also quotes a best-in-class drag coefficient of 0.30 for the Roadster.
At 4.17m long and 1.83m wide, the third-generation two-seater is now 2.1cm shorter and 1cm narrower than its predecessor. However, the Roadster's wheelbase has been extended by 3.7cm to 2.50m to give it 'an even more purposeful stance', according to Audi.
The 2.0-litre TFSI turbo petrol is expected to be the biggest-selling engine, and it's available in front-wheel drive and quattro all-wheel drive form, with either a six-speed manual or dual-clutch S tronic gearbox and produces 227bhp. There is also an entry-level 1.8 TFSI, introduced in time for summer 2016, which is only available with a manual 'box and produces a spritely 177bhp.
Other Roadster models include the diesel 2.0-litre TDI Ultra and the full-fat TTS, which, if you get your kicks from rorty acceleration and lots of fresh air, but still want a civilised daily driver in less thrill-seeking moments, the TTS Roadster could well be for you.
