Best large cars for 2020

Our expert lab and road tests reveal the very best large hatchbacks and saloons available now.

The very best large cars are reliable, economical, practical, and far sharper to drive than an SUV. 

The large car class includes premium models – such as the Audi A4, BMW 3 Series and Mercedes-Benz C-Class. There are also more reasonably priced mainstream designs, including the Ford Mondeo, Skoda Octavia and VW Passat.

With plenty of sleek coupés and saloons available, plus slightly more practical hatchback models, there is bound to be a large car to suit your needs and budget. Provided you choose carefully, that is.

In the tables below are the very best large cars we’ve tested. These are Which? Best Buys that excelled in our lab and road tests, offering decent fuel economy and good reliability.

If you're in the market for an upmarket large car that prioritises passenger pampering, you'll be pleased to know we've also separated luxury models, both new and used, into their own category. This will make it easier for you to find the best large car for your needs.

Plus we’ve picked out the worst large cars we’ve tested, to make sure you don’t waste your money on a car that’s short on space, is uncomfortable to drive or drinks fuel at an alarming rate.

Proof that large cars don't need to be powered by diesel to be economical, this hybrid model excels across the board. It's comfortable, easy to use and is backed up by its maker's rock-solid reliability rating. It's also one of the more affordable large hybrid cars you can buy, sealing its appeal.

If you want to run a car that minimises your environmental impact, this model makes a pretty good case for itself. Its only emission when it's being used is water - yet it's much more feasible to run every day than most zero-emissions cars because its range is good and it can be refuelled quickly rather than plugged in for hours.

If you spend your life driving around town, then this hybrid model could lower your annual running costs. It's very easy to drive, well-built and safe in an accident, too. Poor rear visibility and a small boot count against it, but not enough to deny it a Best Buy rating.

It's been an institution on British motorways for years, and with good reason. This large four-door saloon is comfortable, reasonably economical and superbly easy to drive. Only an awkward-to-load boot and its rather anodyne styling count against it. It's a deserved Which? Best Buy.

This model has always been a strong choice in the large car market, and the addition of plug-in hybrid technology has only increased its appeal. The potential for low running costs hasn't diminished its desirability to keen drivers - it remains powerful and fun to drive, with space for five in its high-quality cabin.

It may not have the white-knuckle driver appeal of some of its closest rivals, but this spacious luxury saloon appeals in other ways. It's impeccably well built, comes with a robust standard equipment list and is impressively efficient. You can't tow with it, but for most people this will be a minor concern.

Successfully dispelling the notion once and for all that hybrids can't be fun to drive, this enormous hatchback is a serious luxury car proposition. With both exhilarating performance and the potential for very low running costs, as well as superbly finished cabin, it's the car for every occasion.

This has traditionally been seen as the model to beat in the luxury saloon market. Its superb quality, class-leading technology and engineering put it in a class of its own. It's very hard to fault, even in the rarefied world of luxury limousines.

This luxury car is made all the better for the addition of plug-in hybrid technology. Not only is it more economical overall than the diesel version, but cabin refinement is improved thanks to the whisper-quiet electric motor and battery which also offers reasonable emissions-free driving range. It's an expensive purchase, but you won't be in the least bit disappointed.

This is a performance powerhouse - a saloon car with the performance to embarrass sports car drivers without breaking a sweat. It keeps the huge five-seat interior of the entry-level model and is no less comfortable on long distances. If you're brave enough, this could be all the car you ever need.

This brand has great experience with hybrid technology, and this old generation limousine shows it off to great effect. It’s supremely quiet and refined and returned acceptable fuel economy in our tests, despite the hybrid system being mated to a very large petrol engine. It’s also superbly well-made and backed up by the brand’s bomb-proof reliability record.

Owners of this particular brand are amongst the happiest on the road, with it consistently scoring highly in our annual car survey. This generation of its large luxury saloon is a particularly fine example of the breed; combining sumptuous build quality with an understated and silky-smooth driving experience. It’s so good that it’s beaten far newer and more expensive luxury saloons for overall driver satisfaction.

This oddly-shaped car sports superb engines, crisp handling and excellent dynamic feedback. Yet it's also superbly refined, with a composed ride and admirable noise suppression. It’s noticeably more practical than the model it’s based on, too.

This popular luxury saloon is very good to drive, whether you opt for a petrol or diesel engine. The diesels are frugal but not quite as inspiring as the petrol versions. The handling and steering are top-drawer. The only real gripes concern visibility and an interior that can be daunting to get used to.

Its styling certainly divided opinion, but in all other respects this was the best iteration of the model we’d yet seen, upon its launch in 2008. It’s supremely comfy and spacious and handles quite well for such a large car. Petrol engines are thirsty.

What to avoid when buying a large car

If there’s one thing a large car should get right, it’s space. Whether driving or sitting in the passenger seats, no one should be short of room in a large car. 

The same goes for the boot. It should be big enough to fit a family food shop, a pushchair and an extra tyre, with room to spare.

It’s easy to assume that a large car will meet these requirements with ease, but that’s not always the case. A big boot doesn’t mean it’s well designed. 

We don’t just measure size: we also consider how easy a boot is to load. A high load lip may not seem like a huge problem – until you’re trying to lift your family’s holiday luggage into it.

A large car should be roomy and comfortable, but ample size and space don't necessarily mean that a large car will be a gas guzzler. 

Our unique testing has found large cars that manage well over 60mpg, while others fail to get over 30, despite the sometimes outlandishly high figures claimed by some manufacturers.

Lastly, don't forget about reliability, which can be the undoing of some otherwise decent and popular large car models. The large car models we'd suggest you avoid, below, largely fall down due to a lack of dependability.

A reasonably priced large saloon is rarely likely to get pulses racing, particularly as it ages, but drivers of this older model are particularly unimpressed. We’ve criticised it for a lack of rear headroom and an awkward boot, but for owners its poor all-round visibility has proved a particular bugbear. A lack of modern technology and iffy reliability seal its fate as the least satisfying large car to own.

How to buy the best large car

From checking you have enough rear passenger headroom to what to look for when buying a premium brand, there's a large car to suit every budget. 

Our tips will show you what to look for and consider before buying a large car.

Large car pros: passenger space and headroom

The main reason for choosing a large car over a medium model is that they offer a greater amount of space for passengers and luggage. However, our tests have shown that just because a car takes up a lot of room on the road, it doesn’t necessarily mean it’s going to be cavernous on the inside.

For instance, you may be surprised to hear that upmarket models such as the Audi A4 and Lexus IS are pinched for rear passenger headroom, and fitting three in the back will be a squeeze.

You needn't fork out for an ultra-luxurious car like the BMW 6 Series GT or Mercedes S-Class to get decent space, though. More sensibly priced practical models in the large car class include the BMW 3 Series, Toyota Camry Hybrid and Skoda Superb.

Premium handling and performance

Don’t think you need to look to a sports car or compact hot hatchback for driving thrills. Some large models are amongst the best cars to drive, with responsive handling and decent long-distance comfort.

Premium German marques such as BMW and Mercedes produce particularly driver-focused large cars, though most manufacturer model ranges have a breadth of engines to suit most tastes and budgets - just watch out for expensive running costs on the most high-performance models.

Large car alternatives: consider buying an estate

Estate cars have fallen out of fashion in recent years, as family buyers turn to SUVs and crossovers for their perceived additional practicality. However, if you don’t like the image of a 4x4, or don’t want to compromise on driving dynamics, a large estate car may prove a better bet.

Estate models are often only a few thousand pounds more expensive than the equivalent saloon they’re based, but often offer much greater boot space with little or no compromise to the car’s other facets.

See our expert pick of the best estate cars.

We test cars more thoroughly than anyone else

Our tests go further than those carried out by other organisations and, because Which? is independent and doesn’t accept advertising or freebies, you can trust our reviews to give you the full, honest and impartial truth about every car we test.

Every car we review is subjected to more than 100 individual tests in a lab, on a test track and on real roads – and we really clock up the distance, driving around 500 miles in every car we test.

Testing in controlled lab conditions means the results we collect are directly comparable between different cars, helping us to determine exactly which models are better and why, and helping you find the perfect car for your needs.

And so you know which cars are likely to prove reliable for years to come, we also gather feedback from thousands of UK car owners through the Which? Car Survey, using it to generate detailed reliability ratings for the cars we test.

To take the guesswork out of choosing your next car, join Which? and you’ll receive access to all our expert reviews and advice.
