BMW 2 Series Convertible vs Audi A3 Cabriolet
Can BMW’s new 2 Series Convertible prove a hit with Brit drop-top fans this summer, and beat its Audi rival?
Summer is here, so what better time to put two small, four-seat cabriolets head-to-head? The latest mid-sized drop-top to hit the market is BMW’s 2 Series Convertible, which blends the elegant styling of its two-door coupé brother with that all-important ability to lift the lid when the sun shines brightly.
However, there’s a fly in the BMW’s ointment – the Audi A3 Cabriolet, which was crowned Best Convertible at our 2014 New Car Awards.
The brands are competing in the same sector, and both offer punchy performance and affordable costs with the diesels we’ve lined up here. With its rear-wheel-drive chassis the 220d Convertible promises balanced handling and decent performance, but the hi-tech, front-wheel-drive A3 2.0 TDI Sport is no slouch.
Both have plenty of badge appeal and, thanks to their electrically operated fabric roofs, surprising refinement, too. There’s only £105 between them (although the Audi has an S tronic dual-clutch box), so the decision will come down to personal choice.
Yet at around £30,000 neither is cheap, and options quickly push up costs. But soft-tops have never been easier to live with, so we put them through their paces to determine the convertible king.

Head-to-head
Electric roof
It’s all about the soft-tops with these cars. Both feature power-folding hoods that can be operated at speeds of up to 30mph – but the A3’s operates marginally more quickly, taking 18 seconds to the 2 Series’ 20 seconds. If you don’t want the top down, you can lower all the windows to leave a big void.
Refinement
A fabric roof can be a big source of extra road and wind noise compared to a hard-top, not to mention a large area that lets heat out. To boost refinement and comfort, BMW and Audi use clever three-layer acoustic hoods that trap more heat and filter out noise. Both are quiet on the move.
Details
Smaller details might be secondary concerns when buying a soft-top, but neat features such as climate control memory and neck heaters can make the difference. As a result, the Audi comes out on top for attention to detail and usability.
Verdict
1st place: Audi A3 Cabriolet
The A3 Cabriolet's broad appeal means it beats the BMW. It’s better to drive, more comfortable and spacious, cheaper and, with superb residuals, will depreciate less. It might cost slightly more to run than the 2 Series, but with less power its performance is still impressive – and the chassis is better. You needn’t make many concessions for running a convertible when it’s this good.
2nd place: BMW 2 Series Convertible
It has more firepower and a bigger boot, but the 2 Series Convertible isn’t as well rounded as the A3 Cabriolet. It’s a vast improvement on its predecessor, with more flowing proportions and enough tech to match the Audi. However, the body control isn’t as good, so it feels less planted. Add in its more cramped, less slick interior, and the Audi stays on top.
Other options for the same price…
New: VW Golf Cabriolet GT 2.0 TDI DSG
Price: £29,325 Engine: 2.0-litre 4cyl, 148bhp
As it’s based on the Mk6 car, rather than the latest Mk7, the Golf Cabriolet isn’t as stylish as these convertibles, but it’s a practical, smart alternative. In high-spec GT trim you get plenty of kit, plus it shares its 2.0 TDI with the Audi.
Used: BMW 420d M Sport Convertible
Price: £30,000 Engine: 2.0-litre 4cyl, 181bhp
Like the look of the 2 Series, but need more practicality? This budget will get you into a nearly new 4 Series Convertible. The 420d delivers similar power, although with a bigger boot and cabin, plus lots of style, it’ll be easier to live with.
