Best small cars for 2024

The best small cars are loved by their owners. And for good reason: they're compact enough to be easy to drive in town and just large enough to be comfortable on long-distance trips.

Regardless of which best suits your needs, you shouldn’t settle for a small or city car that’s unreliable, inefficient or has substandard build quality.

Our independent, in-depth lab tests reveal which small cars are worth buying, and those you should avoid.

What to avoid when buying a small car

Small cars are, well, small, but that doesn't mean they need to feel cramped. We've found models that are deceptively spacious with more legroom than you would expect from the outside. That said, we've found cars that are a tight squeeze for two occupants, let alone five. 

This is especially true of city cars, of which some can only comfortably carry four passengers – and even then they may not want to be there for very long.

Some manufacturers see the small car moniker as a practicality challenge, adding creative storage solutions and smart folding seats. But other manufacturers see it as an excuse, creating cars with small, badly designed boots with high lips that make them difficult to load.

Being smaller and lighter than most cars doesn't mean a low-powered engine will suffice. Our testing has uncovered engines that struggle to get their cars going. While small and city cars are designed for urban use, they shouldn’t leave you struggling to get up hills at motorway speeds. If the engine can't manage this, then you'll be moving up and down the gears too often to maintain your speed.

Finally, no matter how small a car is, there is no excuse for it to be unsafe. Our independent testing has uncovered cars that have sub-standard crash safety.

Are small cars safe?

Small cars are inevitably built to a price – but there's no excuse for car manufacturers to skimp on safety equipment to keep costs low. 

We've found that cheaper versions of some models are missing active safety technology, such as AEB (Autonomous Emergency Braking) – without this it’s now near impossible to get a full five-star Euro NCAP crash safety rating.

We automatically class any car that gets three stars or less a Don’t Buy car. City cars often fall foul of this as their low prices often prohibit the inclusion of active safety technology.

Are small cars cheaper to run?

Small cars are generally cheap to run. But if you’re particularly concerned about running costs, consider fitting low rolling-resistance tyres, which require less energy to turn. Opting for the smallest wheels possible will also minimise the energy needed to get your car going.

Small cars haven’t been neglected in the switch to sustainable mobility. There are several excellent hybrid and electric models that could severely reduce your running costs, particularly around town.

However, if you're planning to venture beyond the city limits, you may find that a less powerful petrol engine runs out of puff on faster roads, on steep inclines or when the car is fully loaded.

Most manufacturers are making their smaller engines more powerful and efficient with turbochargers. Older non-turbo motors (usually fitted to the cheapest models in the range) are still available and are usually best avoided, unless a low price is your ultimate concern.

When we test cars, we look at in-gear acceleration and see how well a car accelerates. This simulates moving to a faster lane on the motorway or overtaking a slow-moving vehicle on a country road.

Fuel bills may be low, but don't assume that insurance for small cars will also be cheap. Higher performance versions of the Mini, for instance, are ranked as high, or even higher, than some BMW 3 Series models in terms of insurance risk, so choose carefully.

To minimise the potential for high insurance premiums, choose a model fitted with autonomous emergency braking (AEB). This reduces the likelihood and severity of low-speed collisions and cars fitted with it can normally be insured for less.

Are small cars reliable?

Choose your small car carefully. Based on our latest reliability survey, this car class has a fair number of unreliable models – including one example where almost 40% of owners in our survey experienced at least one fault. 

However, there are always exceptions. See our guide to the most reliable cars for more.

Are small cars practical?

The modest dimensions of small cars doesn't necessarily mean they will prove impractical as family runabouts. 

Many, such as the Skoda Fabia, offer a spacious boot thanks to clever packaging. Others such as the Honda Jazz have innovative interior storage solutions, such as clever rear seat bases (named 'magic seats' by Honda) that flip up to create a large vertical load space. 

Most models are five-door and come with Isofix points for easy and secure child-seat installation.

You're unlikely to be able to fit a child seat in the centre rear seat, though, as the seat base is usually too small. Whatever car you choose, make sure your child's car seat is a Best Buy. Our independent crash tests have uncovered child car seats that will put your child at risk. See our guide to the best child car seats for more.
