The four-seat Audi A5 Cabriolet range features a folding fabric top roof, with a choice of seven engines and a wide range of high-end options.
The top-of-the-line S5 model also gains a convertible variant, boasting a newly developed, supercharged 3.0-litre V6 engine with direct injection.
Like all open-top Audi's, the A5 uses a classic fabric top which opens in just 15 seconds - and closes in 17 seconds.
The fully automatic open/close system is standard on all A5 Convertibles, although an acoustic top is optionally available which reduces wind noise and is comparable to a hardtop roof.
A clever folding design means that even when the roof is down very little boot space is lost - maintaining 320 litres of usable storage space.
In addition to this, the rear-seat backrest can be folded down creating a pass-through between the luggage space and the interior, which increases the storage volume to a generous 750 litres.
The A5 Cabriolet is being launched with three petrol engines and two diesel engines, with power outputs ranging from 132 kW to 195 kW - all featuring direct injection technology.
High-powered models also benefit from Audi quattro all-wheel drive with an optional sports differential which distributes power between the rear wheels.
A choice of three transmissions is also on offer: a six-speed manual transmission, the continuously variable multitronic, and the seven-speed S tronic.
Delivery of the first A5 Cabriolet models will begin in the second quarter of 2009.
