Audi's stylish A4 Cabriolet range is to be revamped in time for summer 2006, with the S4 Quattro headlining the range.

In its current guise, the A4 Cabriolet provides one of the widest ranges on the market with a large choice of engines, including a diesel, and a four-wheel-drive option available. As you would expect from the German marque, each A4 Cabriolet is superbly crafted, but they also boast exceptional performance: even the base model 1.8T can reach 140mph, while the Quattro S hits 155mph flat out. The 1.8-litre engine configuration will continue with the new model, joined by new 2-litre and 3.2-litre V6 petrol powerplants and a choice of two diesels: 2-litre TDi and a high-performance 3-litre V6 TDi. The newly announced S4 Quattro retains its 4.2-litre V8 engine although its price does rise to £42,980.

For those unable to reach the heady heights of Quattro S ownership, Audi is offering sports upgrades across its range. The 'Sport' package consists of larger alloy wheels and tyres, front sports seats and a paddle gearshift on automatic models, all for a cost of just £750. The 'S-line' package is rather more expensive, although for £2,400 you do get a full leather interior and 18-inch alloy wheels, while personalised S-line bodywork can be added for an additional £750. These options coupled with six engine options result in an almost endless combination of different models.

The A4 Cabriolet remains well equipped, each model sporting an electric hood, windows and mirrors, CD player and climate control. However, the facelift sees a hike in prices, which potentially undermines its advantage over the likes of the BMW 3-series convertible and Mercedes CLK.

Audi also claims to have improved the road manners and responsiveness of the new A4 Cabriolet, and it still offers a sound, classy alternative within the sports Cabriolet class. However, it remains an expensive choice, and if two seats are all you need, then Audi's TT convertible is a cheaper option. Later this year BMW's new 3-series should rear its head, which is likely to create a bit of difficulty for the Audi.
