Best four-seat convertibles

Put the roof down and bring the family along: these are the best four-seat convertibles

There's no need to forego the joys of driving with the roof down if you find yourself with more than one passenger.

There are plenty of convertibles that can carry at least four people – and we don't just mean two adults in the front and two toddlers in the back. We've found the best open-top cars that have proper rear seat space.

Most models still require some compromise. For example, you'll often find that there's a reduced amount of legroom because the folding roof requires greater boot space. Headroom can be limited with the roof up but there's an obvious solution - as long as it's not raining.

One other consideration is that many four-seat convertibles can't be fitted with wind deflectors when all four seats are filled. This barrier is typically installed over the rear seats. When the side windows are raised, it creates a bubble of air inside the car which considerably reduces the air buffeting when you drive along.

Audi A5 Cabriolet

Latest Audi A5 Cabriolet deals from £13,500
Finance from £211 per month

The A5 Cabriolet is a classy convertible, combining solid build quality, powerful engines and a superb interior. As well as the hi-tech options available in the A5 Coupe, the Cabriolet has some unique features, including microphones in the seatbelts for clearer hands-free phone calls, as well as a neck-heating system.

The roof is made of several fabric layers to reduce noise when it's up. It folds in just 15 seconds, while you're driving at speeds of up to 31mph.

Rear seat space is reasonable but headroom is tight, at least when the roof is up. The boot is impressively large: 320 litres with the roof stowed or 380 litres with it deployed.

It’s not the most nimble of convertibles, but it does absorb bumps well. Like most convertibles, you can feel slight wobbles in the car's structure because of the lack of a fixed roof, but it’s nothing serious. Audi’s 2.0 TDI Ultra diesel engine is a cracker: powerful, smooth and frugal.

BMW 4 Series Convertible

Latest BMW 4 Series Convertible deals from £17,990
Finance from £244 per month

The 4 Series convertible has a metal folding roof as opposed to a fabric one, which makes the car quite heavy and certainly not as sprightly as its lighter and stiffer coupe equivalent.

The advantage is that it's much quieter when up, and the car is more secure too.

Given the car's weight, the diesel engine is a good choice, for its stronger pulling power, which makes accelerating away feel smoother and less strained.

The 4 Series convertible is a handsome car with an equally attractive and well-built interior. There’s plenty of space in the front while legroom is pretty generous in the rear. Headroom at this end of the car is pretty tight, though, when the roof is up. The boot is a decent size at 370 litres but when the roof is down, this shrinks to 220 litres.

Mercedes C-Class Cabriolet

Latest Mercedes C-Class Cabriolet deals from £23,980
Finance from £355 per month

The hood on the good-looking C-Class Cabriolet is a fabric affair that blocks out all but the worst wind noise.

Extra support has been added to the car to take into account the loss of rigidity due to the absence of a fixed roof compared. This has eliminated most wobbles in the car's structure, but adds 120kg to the car's weight compared with the coupe version.

This does mean that the C-Class Cabriolet crashes into potholes with more force than the fixed-roof Coupe, but this can be fixed by opting for the optional air suspension, which restores the smooth ride.

The interior is as stylish as the exterior, with lots of artificial leather and aluminium. A sat nav is standard but the dashboard screen is not quite as intuitive as BMW’s equivalent.

It has the company’s Airscarf neck-warming system as standard. Front seat space is generous but those in the back won't feel quite so well provided for, since head and legroom are in short supply. A 4 Series is roomier.
Roof up, the Mercedes’ boot is bigger than the BMW’s and can be made larger still by dropping the rear seat backs. However, folded, the boot is much smaller.

Range Rover Evoque Convertible

Latest Range Rover Evoque Convertible deals from £29,503
Finance from £353 per month

It’s not especially cheap, but if you're looking to make a statement, then the Range Rover Evoque Convertible certainly stands out.

The Evoque convertible sport utility vehicle (SUV) is the only car of its type on the market. It retains the rugged off-road ability of the standard Evoque – so it can drive through water that's half a metre deep, crawl up and down mountains, and navigate deeply rutted tracks. Yet It’s also perfectly happy cruising around town or out on the motorway.

Because the convertible was designed after the other versions of the Evoque, which means that it's quite compromised, with a small boot that has a tiny letterbox-shaped opening, and extra support to make the car more rigid, which increases the car's weight noticeably.

As a result, it doesn't feel sporty ot nimble: it's best to put the roof down, cruise along smoothly and soak up the glances - admiring or not.

Mercedes S-Class Cabriolet

Latest Mercedes S-Class Cabriolet deals from £93,000
Finance from £1,266 per month

If you’re looking for the ultimate in opulence for your four-seat convertible, the Mercedes S Class Cabriolet probably offers the most luxurious experience outside of a Bentley or Rolls Royce.

Its elegant, swoopy bodywork wraps up an interior that’s crammed with high-tech gadgets, beautifully finished trims and expensive-feeling leather. It’s no sports car, but it is a magnificently refined cruiser, and AMG versions are stupendously fast.

The only significant compromise you’ll have to make is the rear seats, which are a little cramped when the roof is up – but there’s still plenty of space for the occasional occupant.


Ford Mustang Convertible

Even people with very little interest in – or knowledge of – cars will know what a Ford Mustang is. It is the ultimate good-time crising convertible, a slice of pure Americana. And the current generation is the first to be offered in the UK with right-hand drive.

Compared with a Mercedes, BMW or Audi convertible, the Mustang delivers loads of equipment for the money, and the big V8 petrol version is fast and sounds great. Coupled with either a six-speed manual gearbox or a slick 10-speed automatic, it makes the Mustang a joy to drive.

The interior isn’t as classy as you’ll find in a BMW or Mercedes, and access to the rear seats – as well as the space in the seats themselves – is a bit tight. But when the sun’s out and you’re cruising down your favourite road, none of that will matter.
