Are cars getting bigger in the UK?

Yes, modern cars have generally become larger over the past couple of decades. Many popular models are now longer, wider and heavier than their earlier versions, partly due to safety requirements, added technology, electric vehicle batteries and growing demand for SUVs.

Why are modern cars so much bigger?

Modern cars are bigger because drivers expect more space, comfort, safety technology and practicality. Crash protection, larger wheels, batteries in electric cars and the popularity of SUVs have all contributed to cars becoming larger over time.

Are UK parking spaces too small for modern cars?

Many UK parking spaces were designed decades ago, when cars were generally smaller. As a result, modern cars can feel tight in multi-storey car parks, supermarket bays and residential streets, especially wider SUVs and electric vehicles.

Are SUVs too big for UK roads?

Some SUVs can feel large on narrow UK roads, especially in older towns, cities and residential areas. However, not every SUV is impractical. The key is choosing a car that suits where you drive and park most often.

Do bigger cars make roads less safe?

Larger and taller vehicles can create safety concerns, particularly for pedestrians and cyclists, because they may reduce visibility and take up more road space. However, modern cars also include advanced safety systems, so the issue is more about balance than size alone.

Are electric cars bigger than petrol cars?

Many electric cars are larger and heavier than petrol cars because of their battery packs and the way they are designed. However, there are also smaller electric cars available, and not every EV is oversized.

What should I check before choosing my next car?

Before choosing your next car, check its length, width, turning circle, boot space and parking technology. It is also worth thinking about where you park most often, whether you use multi-storey car parks, and whether the car will feel easy to live with every day.

Are cars getting too big for Britain's car parks?

Modern cars are bigger, heavier and more comfortable than ever, but are they now outgrowing Britain’s roads, parking spaces and everyday driving habits?

There are few things more humbling than trying to get out of a modern car in a tight multi-storey car park.

You reverse in carefully, fold the mirrors, line everything up, feel quietly smug about your parking, then realise you can only open the door about six inches before it kisses a concrete pillar or someone else’s enormous SUV.

I love cars. I love big comfy SUVs, clever electric cars, luxury interiors and all the tech that now comes with them. But even I have to admit that some modern cars are starting to feel a bit oversized for everyday British life.

And, as it turns out, it is not just in my head.

New analysis from Vehicle Data Global, reported by Business Motoring, says the average car footprint has grown from 7.67m² in 2006 to 8.61m² in 2026. That is a 12.3% increase, or almost one extra square metre per car. On a typical 200-metre residential street, VDG estimates that could mean space for around four fewer cars than 20 years ago.

That explains a lot.

It is not just SUVs

Whenever this topic comes up, everyone points at SUVs. And yes, there are more of them. You only need to stand by a school gate, drive through Brighton, or attempt to park at a busy supermarket to see how dominant SUVs have become.

But this is not only about people buying big 4x4-style family cars. Normal cars have grown too.

According to the same VDG analysis, the Vauxhall Corsa has grown its footprint by 19.3% since its original launch. The Ford Focus has increased by 13.4%, while the Volkswagen Golf is up 12.4%.

That is what I find most interesting. The cars we still think of as sensible, everyday choices are much bigger than they used to be.

A modern supermini is not quite as “mini” as it once was. A family hatchback is now knocking on the door of what would have once felt like a much larger car. And once you add bigger wheels, chunkier bumpers, batteries, safety kit and all the other modern expectations, you end up with cars that are genuinely more difficult to thread through older British towns and car parks.

Parking spaces have not kept up

The problem is that Britain has not exactly redesigned itself around these bigger cars.

The RAC says a typical UK parking space is around 2.4 metres wide and 4.8 metres long, with those dimensions first introduced roughly 50 years ago when cars were much smaller. It also notes that on-street parallel parking can be tighter, with a minimum parallel bay width of 1.8 metres referenced by the British Parking Association.

That might have worked nicely decades ago. It does not always work so well when you are trying to park a wide modern SUV, an executive EV or even a larger family hatchback with big mirrors and thick doors.

I notice it most in places like Brighton and Hove, where a lot of streets were never designed around the size and volume of cars we have today. You can have residents parking on both sides, delivery vans trying to squeeze through the middle, cyclists, pedestrians, bins, scooters and then someone trying to parallel park a car that feels like it belongs on a motorway rather than a Victorian side street.

No wonder everyone is stressed.

The safety bit matters too

This is where the conversation gets more serious.

A 2026 report from Transport & Environment and Clean Cities found that newly sold cars are getting longer by around 1.2cm every year and taller by around 0.5cm every year. It also warns that, if current trends continue, cities could lose between 8.5% and 14% of on-street parking capacity by 2040.

The same report raises concerns about the safety impact of taller vehicles, particularly around pedestrians, cyclists and children. Higher bonnets can reduce visibility and change the way a person is struck in a collision.

That does not mean every large car is bad. I do not buy into the idea that we should all be shamed for liking a comfortable SUV or needing a bigger car. Some people genuinely need the space. Families, dog owners, people with mobility needs, businesses and high-mileage drivers all have different requirements.

But I do think we need to be more honest about the trade-off.

A big car might feel safer and more comfortable for the person inside it, but it also takes up more room in a shared environment. Roads, streets and car parks are shared spaces. The bigger the cars become, the more everyone else has to work around them.

Electric cars add another layer

Electric cars complicate this even more.

On one hand, EVs are brilliant around town. They are quiet, smooth, clean at the point of use and usually very easy to drive. On the other, many electric cars are heavy and quite large because of the battery packs, safety structures and the current obsession with SUV body styles.

That is why I love seeing smaller EVs come through. Not everyone needs a huge electric SUV with a massive battery. Plenty of people would be better served by something compact, efficient and easy to park.

Real-world usability is not just about how far a car can go on a charge. It is also about whether it fits into your actual life. Can you park it outside your house? Can you open the doors in your local supermarket car park? Can you get it down the roads you use every day without wincing?

Those questions matter.

So, are cars too big?

Some of them, yes.

That does not mean I want boring cars. It does not mean I want everyone forced into tiny city cars. And it definitely does not mean I have suddenly stopped enjoying a big, plush SUV with a great driving position and a huge boot.

But I do think the industry has reached a point where size needs to be part of the conversation again.

For years, bigger has been marketed as better. Bigger screens. Bigger wheels. Bigger grilles. Bigger batteries. Bigger boots. Bigger road presence.

But on a wet Tuesday in a tight car park, bigger can just mean more awkward.

For me, the best cars over the next few years will be the ones that feel spacious without being silly, practical without being oversized, and safe without turning every residential street into a squeeze.

Because as much as I love cars, I would also quite like to be able to get out of one without performing yoga against a concrete pillar.
