Best small SUVs and crossovers for 2023

The best small SUVs and crossovers give you a commanding high-rise view of the road, a practical and spacious interior, and large door openings. They can also typically be powered with smaller engines than larger full-sized off-roaders, so you can have the tough aesthetic and road presence of a 4x4 without the higher running costs of a full-fat SUV.

However, despite cars in this class typically following a similar recipe, our tests continually find models that don’t meet expectations.

Pick the wrong one and you could end up driving a car with mediocre fuel economy, middling driving experience, little safety equipment and so-so passenger space. In fact, one of the most popular models we’ve tested falls short against its rivals due to high CO emissions at motorway speeds – something the official tests don’t cover.

Scroll down the page for the very best small SUVs and crossovers we've tested, including new EV and hybrid models.

What is a crossover?

The term 'crossover' is a fairly recent addition to the new-car lexicon. It's typically used to describe smaller SUVs, which are a crossover between a conventional small hatchback and a full-sized 4x4. 

The term is also often used to describe medium-sized SUVs that do without the off-road hardware of proper 4x4s, as well as high-rise MPVs, and other models that blend features of two traditional types of car. But for the most part, it's best to think of a crossover as a small, road-biased SUV.

Best used small SUVs and crossovers

Demand for small SUVs has really grown in the past few years and there is a rapidly-growing selection of high-quality used models. Typically, these won't be available with the latest mild or full hybrid tech (depending on model), but this will change in time. 

As SUVs can come at a premium, buying used can be a great way to get more for your money. Our experts select the very best models, below.

Small SUVs and crossovers to avoid

Pick a dud and you could end up with a car that costs a fortune to run, expels way too many pollutants, is unsafe in the event of a crash and breaks down on every other journey.  

Be confident in your choice by checking our reviews – and avoiding the cars below. We don’t award a Best Buy to a car that produces too many emissions nor do we recommend a model that scores poorly in Euro NCAP safety ratings, or is extremely unreliable. 

What's the difference between a compact and small SUV?

Compact SUVs are typically the smallest models available, and are normally little more than regular small hatchbacks given mildly raised suspension and beefed-up body styling to give a more rough-and-tumble look. Examples include the Honda Jazz Crosstar and the Audi Q2.

While there are no hard and fast rules (sizes and shapes can vary greatly between manufacturers), small SUVs are normally slightly larger and have a conventional SUV shape. However, other than an increased ride height and commanding driving position, they're normally no better equipped for off-road use than a hatchback or saloon model. Popular examples include the Volvo XC40 and the Volkswagen T-Roc.

What's the difference between a small and large SUV?

If you plan to regularly venture on to rough tracks or go off-road entirely, then you should at least consider a model with full four-wheel drive.

Small SUVs may look like 4x4s, and they should cope just fine with the occasional gravel track, but there aren't many that will tackle real off-road conditions with ease.

To improve efficiency, many crossover models are two-wheel drive and are designed primarily for use on tarmac. 

Full-sized SUVs and 4x4s are often fitted with locking differentials and low-range gearboxes – off-road-specific hardware that you’ll struggle to find on the spec list of nearly all crossovers.

Some crossover models now come with multi-mode traction control systems in place of four-wheel drive. These allow the driver to select the best setup for different surfaces (gravel or snow, for example), with the system altering its intervention to allow for the best possible traction.

With their two-wheel drive and small engines, crossovers aren't necessarily the best tow cars, either. You'd be better off with a 4x4 or a four-wheel drive large car if you want to tow a caravan or large trailer.

If you want a vehicle to take off-road, see our expert pick of the best large SUVs and 4x4s. 

What to look for when buying a small SUV

The small SUV and crossover class is a relatively new one in motoring, but it has quickly become one of the most popular and is now responsible for some of the bestselling models in the UK. The boom in popularity meant every manufacturer wanted a slice of the action, releasing their own small SUVs – with mixed results.  

A high driving position is one of the major benefits of owning a crossover SUV. It gives a commanding view of the road and helps make people feel safer while driving.

However, depending on model, you may not be any better off in terms of load space or passenger comfort by paying the premium for a small SUV instead of buying a similarly sized alternative.

For ultimate long-distance comfort, large saloons are likely to fit the bill better, and most will compete with small SUVs in terms of passenger and luggage space.

If you’re simply looking for an easy-to-use, practical family car, then you should also consider one of our best estate cars. These offer oodles of boot space without compromising on cabin space, and are available in all manner of sizes and specifications to suit every requirement and budget. And it doesn't have to be functionality over style these days, either; many new estate cars look great, too.

Where the extra height and taller doors of SUV models does come in handy is in fitting a child car seat, simply because the seats are easier to access in the first place.

The appeal of the raised driving position and being seen in a stylish SUV is too much for some to resist, but objectively there is little else to distance them from the rest of the family-car market.

Are small SUVs expensive to run?

Despite the stereotype of SUVs being fuel-guzzlers, that's not always the case with small SUVs; our testing found that crossover cars have one of the biggest disparities between the most and least-efficient models: 

• Choose the right car and you can expect up to 75.3mpg
• Choose the wrong model and you’ll get just 32.1mpg. 

There are models that guzzle gas as much as their larger SUV cousins, but you shouldn't tar them all with the same brush. There are several small SUVs that are as cheap to run or cheaper than small cars.

In particular, there is a growing number of hybrid models in the small SUV class, ranging from conventional hybrids, such as the Hyundai Kona Hybrid and the Toyota C-HR, to plug-in (PHEV) versions such as the Kia Niro PHEV. These could reduce your fuel bills considerably, particularly if you do most of your driving around town.

But be careful. If you tend to drive further afield and won't be able to plug in regularly, a PHEV could work out more expensive.

Most people may assume that a PHEV's emissions-free driving range gives them a one-up on conventional hybrid models, which have a comparably far shorter electric driving range. And it would seem so, if you go by manufacturer-published fuel economy figures, as most models have an impressive, three-digit mpg figure. This is because official fuel-economy tests for PHEVs extrapolate figures from their claimed electric range. 

Our own independent tests are based on actual energy and fuel consumption over a fixed distance (100km for comparability purposes). This means we can give you an accurate breakdown in our plug-in hybrid car reviews of just how expensive PHEVs can be to run in any given situation, which is necessary given their varying fuel and electricity consumption.

We also include a motorway test to better reflect real-world driving. For more information, see how we test cars.

Are small SUVs safe?

Don't assume compact SUVs and crossovers are safer than other car classes. Despite the imperious feeling of security given by a commanding driving position, crossover SUVs are often no more protective in a crash than a conventional hatchback.

Make sure you check whether autonomous emergency braking (AEB) has been fitted, as sometimes this is only available as an option on cheaper models. AEB systems use sensors and cameras to monitor the road ahead, and alert the driver to an impending collision. It will automatically perform an emergency stop to reduce the effects of the collision.

It's also worth checking the car has electronic stability control (ESC) fitted. It's been mandatory since 2014, but some older used models may go without this essential electronic safety aid – it drastically reduces the potential for loss of control in tricky conditions.

At Which?, we don’t think top-notch safety should be optional. That's why any car that performs particularly poorly for safety in our assessments, or is awarded three stars or fewer after crash testing by official safety organisation Euro NCAP, is automatically made a Don't Buy. Unfortunately, there are small SUVs and crossovers that we won't recommend because of their low safety ratings. Find out which cars didn't make the grade: Don't Buy cars.

Should you buy a small SUV or a hatchback?

Crossovers are sometimes marketed as city-friendly SUVs, but they're almost always still larger than the hatchback or other models they’re based on. This is because they're both longer and wider. 

You may find a conventional small or medium-sized hatchback more suitable for your needs, particularly if you regularly have to negotiate narrow streets and tight parking. However, the additional ground clearance you get with a crossover gives you that extra bit of breathing space if you encounter a savage speed bump or pothole. 

Parents will appreciate the extra height, higher roofline and larger doors when fitting child car seats or loading up the car for a weekend away. The greater weight and typically higher centre of gravity doesn’t tend to make for a thrilling drive – but there are exceptions.

We test cars more thoroughly than anyone else

Our tests go further than those carried out by other organisations and, because Which? is independent, 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 300 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 vehicle we test. This is all so we can give you an accurate miles-per-gallon figure that you can rely on. We also include a motorway test – something that official tests don't cover. 

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

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