MINI Cooper Convertible vs Fiat 500C vs DS 3 Cabrio

Supermini cabrios balance open-air glamour and efficiency; can the new MINI Convertible compete against DS and Fiat rivals?

If you’re looking for fun behind the wheel this summer, what better way to welcome the sun than with a compact convertible? Despite our not-so-favourable climate in the UK, we love cabriolets – and manufacturers have capitalised on our drop-top desire by offering many superminis in soft-top form.

MINI’s Convertible is the latest to hit the market. It offers the same cute looks and fun-to-drive character as the hatch, but with an added injection of style thanks to its fabric roof.

Meanwhile, with the DS brand now standing separately from parent company Citroen, the recently refreshed DS 3 has been made available in Cabrio form. The fixed-roof version lost out on test to the MINI hatchback, but can the convertible turn the tables?

Best convertible cars

Both face Fiat’s facelifted 500C. While the convertible city car is quite a bit cheaper than its competitors here, it still offers chic design in a compact body as well as a peel-back roof.

Compared with its rivals, the MINI has an added ace up its sleeve: it’s the only full convertible of our trio. So, what’s the best for soaking up the rays this summer? Read on to find out.

Head to head

Roof round-up

There's no getting away from the fact that the DS 3 Cabrio and Fiat 500C feel less special than the MINI – and it all stems from the roof. The other cars resemble their regular hatch counterparts fitted with a large sunroof, while the MINI manages to combine a real open-air driving experience with an accessible price and affordable running costs.

Style vs substance

None of our trio is likely to win any practicality prizes, and even though the DS 3 has the biggest boot, its letterbox-sized opening means you won’t be able to fit any large suitcases in there. The load area is more accessible in the MINI, with a tailgate that folds out and a rear deck that lifts up.

Frugal and fun

These three contenders prove that downsized engines can still be fun. The Fiat feels unique, while the DS 3 and MINI are more similar to drive thanks to their three-cylinder turbos. But the MINI’s powertrain just seems crisper, with a tauter gearbox.


First place: MINI Cooper Convertible

In virtually every way the MINI has the measure of the DS 3. It’s cheaper, more efficient and better to drive – but, importantly, the fully folding roof adds an extra dimension to the experience that neither rival here can compete with. Add a modicum of practicality, and the Cooper Convertible comes out on top. Just watch the price when choosing from the costly options list, though.

Second place: Fiat 500C

Low CO2 emissions and an affordable price tag make the 500C an attractive compact convertible. It’s not the fastest choice, but speed isn’t everything. The focus is more on fashion, which is where the Fiat scores highly. It’s also still good fun from behind the wheel, but should be frugal to run. However, the small boot and back seats mean the other cars here are more practical options.

Third place: DS 3 Cabrio

It's lacklustre to drive and doesn’t feel as fun as the MINI or Fiat. Combine this with poor predicted residual values, higher running costs and an elevated price, and the DS 3 Cabrio comes third. There’s plenty to like – including the updated styling and customisation options that keep the Cabrio in the running – but compared to the high-quality MINI the DS seems on the pricey side.

Other options for similar money

New: Mazda MX-5 SE 1.5 Price: £18,495 Engine: 1.5-litre 4cyl, 129bhp

Mazda MX-5 front quarter

While it only seats two, the Mazda is a more performance-focused alternative for just £20 more than the MINI. The revvy 1.5-litre petrol engine is great to drive and looks sharp – although the base SE model is sparse inside.

Used: VW Golf Cabriolet 1.4 TSI SE Price: £18,500 Engine: 1.4-litre 4cyl, 120bhp

VW Golf Cabriolet

It's based on the previous-generation Golf, but VW’s compact four-seat convertible offers more space than the MINI, plus a premium image. At this price, you’ll be looking at a low-mileage used model in SE spec, which brings Bluetooth and DAB.
