The new Audi TT Clubsport Quattro promises to be one of the fastest production TTs ever

Its official: the crazy roofless Audi TT Clubsport Quattro will go into production this year.

The 300bhp four-wheel-drive Audi TT Clubsport Quattro – which we reported on last week – is an open-top roadster with no fixed or folding roof and features a rakish windscreen.

This new Audi TT Clubsport Quattro promises to be one of the fastest production TTs ever – the German carmaker has boosted the 2-litre TFSI engine’s power to “break the magic 300bhp barrier", which is more than the first E36 BMW M3.

Audi has not released official performance figures for the Clubsport Quattro TT, but expect a 0-62mph time of less than six seconds and a top speed of around 155mph, thanks to the car’s permanent all-wheel-drive and lightweight construction.

The Clubsport Quattro TT also showcases Audi’s super-quick dual-clutch automatic gearbox – dubbed ‘DSG’ – with steering-wheel mounted shift paddles.

Audi first showcased the roofless TT as a concept at the 2007 Essen motor show and will present a production-ready model at a meet for Audi and Volkswagen enthusiasts dubbed “Worthersee Tour”. Audi will also display the storming new Audi A3 TDI Clubsport Quattro, and the Audi R8 TDI Le Mans racecar.

But despite ditching the roof, Audi claims the all-new Clubsport Quattro TT will offer up maximum protection in the event of the car rolling over, thanks to “two massive rollover bars” which will protect driver and passenger.

Audi has garnished the Clubsport Quattro TT’s interior with lashings of aluminium, including the gearshift paddles, door pull handles and pedals, and has fitted the steering wheel from the Audi RS4 and Lamborghini Gallardo.

Audi has announced a limited production run of the hot new Audi TT Clubsport Quattro.
