Real MPG: most economical cars for town driving

What Car?'s Real MPG tests show what you can really expect from a car, and here we reveal the models that perform best if you do most of your driving on congested urban roads...

For many, driving through congested towns and cities is a daily occurrence, whether you live in one or have to travel into one for work. Heavy traffic means lots of stopping and starting, which can have a huge negative impact on your fuel economy.

However, there are cars which can lessen this impact. Indeed, all the models we’ve listed below returned more than 60.0mpg during the town portion of our Real MPG test — with the most efficient car managing more than 100 miles from a single gallon of petrol.

Here we count the top 10 cars that will save you the most around urban areas, as well as the three which will have you stopping at the petrol station most often.

How we test for a car's Real MPG

Most of the official WLTP and NEDC fuel economy figures that appear in brochures are more generous than how the car would actually perform in the real world. This is why we carry out our own Real MPG tests.

Each car is tested on a rolling road under laboratory conditions, and they undertake a real-world-inspired driving route comprising town, motorway and country driving. This eliminates the chance of any uncontrollable variables – like weather or traffic conditions – affecting the accuracy of our results, and we avoid unrealistic driving scenarios or ‘hypermiling’ techniques.

We also check the tyre pressures of each car to make sure they’re set to the manufacturer’s recommended levels, and ensure the climate control is set to 21 degrees. If the car has manual air conditioning, the temperature dial is set to the midway point and the fan speed to its lowest setting. Headlights and any other electric equipment, such as the stereo, are also switched off.

The Real MPG results are calculated using the average data from an exhaust connection, which measures the car’s emissions at every second.

The Toyota Yaris Cross is the only car we’ve tested to manage triple-digits in the urban portion of our tests, and this isn’t the only place it excels – it’s also the most economical car we’ve tested overall. At the heart of that efficiency is its hybrid system, combining a 1.5-litre petrol engine with an electric motor that can do a lot of the heavy lifting while you’re driving around town.

Not only will it minimise your fuel bills, but it also offers a comfortable interior and a lofty driving position that many SUV fans will appreciate. On top of that, its hybrid system allows it to run purely on electric power at low speeds, and there’s also a four-wheel-drive option. There are rivals that are smoother to drive and more spacious, such as the Skoda Kamiq or VW T-Roc, but nothing beats the Yaris Cross when it comes to sheer efficiency.

Looking at its big, heavy SUV stature, you wouldn’t expect the Toyota RAV4 to be as frugal as it is, but, much like the Yaris Cross, it has an efficient hybrid system that does a lot of work to keep your running costs low. With a 2.5-litre engine combined with a powerful electric motor, the RAV4 has a total output of 302bhp, which makes it capable on faster roads. It can run purely on electric power at low speeds, so it feels right at home in urban areas, too.

On top of the RAV4’s low running costs, Toyota has a stellar reliability record, so hopefully you won’t be spending too much on repairs, either. However, the RAV4 isn’t quite as much fun to drive as the combustion-only Mazda CX-5, nor does it offer the seven seat layout of the Skoda Kodiaq.

Toyota scores an efficiency hat-trick with the Corolla, another model that benefits from the brand’s expertise in hybrid technology. It’s described by its maker as a “self-charging hybrid”, which whilst slightly misleading, refers to the ability for the car to top up its battery without the need to plug it in anywhere. Like the other Toyota models previously mentioned, it can power the car at low speeds without the help of the petrol engine.

We’re huge fans of the Corolla, thanks to its comfortable ride and fantastic standard kit, which made it our 2024 Family Car of the Year. But if you’re looking for a car with lots of rear passenger space, you’re better off with the likes of the Ford Focus or Seat Leon, which are much roomier in the back.

The Swace may carry a Suzuki badge, but don’t let names fool you – because as appearances suggest, it’s actually a Toyota Corolla Touring Sports. The reason behind its exceedingly low running costs is the exact same 1.8-litre hybrid system that you get in entry-level versions of its Toyota twin, which is particularly efficient around town.

So, not only is it frugal to run, it’s also cheaper to buy than the entry-level Corolla Touring Sports, while still offering a comfortable ride and plenty of standard kit. There are fewer trims and engines to choose from, though, and the infotainment system is nothing to write home about.

The Honda Civic is in good company with all the other hybrids on this list, but there is something slightly different about the way its 2.0-litre engine and electric motors work together. The Civic’s e:HEV setup means that the petrol engine only powers the front wheels at higher motorway speeds, so around town, it instead generates electricity to feed to a pair of electric motors.

Alongside efficiency, the Civic also offers heaps of standard kit and an enjoyable drive, although it’s not quite as fun as a Ford Focus or Seat Leon. If you’re a fan of the sports car feel, then you’ll like the low driving position, and visibility isn’t sacrificed either, thanks to its slim windscreen pillars and low dashboard.

WLTP MPG 68.8mpg | Real MPG Average 59.9mpg | Town 80.0mpg | Motorway 46.7mpg | Rural 74.1mpg

The latest version of the Yaris returned an average real-world score of 59.9mpg, making it the second most efficient car to ever go through our Real MPG tests. While it’s not as efficient around town as some other models, a figure of 80.0mpg on urban roads is nothing to be sniffed at, and it’ll still save you a decent amount in running costs.

However, where the Yaris excels in frugality, it scrimps on interior space and quality. There isn’t much room for rear passengers to stretch out, and the poorly-hidden scratchy plastics make it feel a lot less upmarket than the likes of the Peugeot 208 and VW Polo. Despite this, it comes with plenty of standard equipment and benefits from Toyota’s fantastic reliability record.

What’s better than one efficient Yaris? Two, of course. This previous generation model may be older than the other version on this list, but it’s still thoroughly economical and very cheap to run, returning the same impressive score of 80.0mpg in the urban portion of our tests as the latest model.

It feels right at home in town, too, with light steering that doesn’t feel overly comfortable on the open road, but is fine for pootling around narrower streets. What’s more, it offers plenty of interior space, and you won’t have to spend too much to put one on your driveway, with used prices starting from just £3000.

Though it may be small in size, the Honda Jazz is deceptively spacious inside. And, not only is it good to drive and well equipped, but it’s also wonderfully efficient, returning a respectable 68.8mpg in the town portion of our tests. Like the other cars in our top 10, it benefits from a hybrid system, meaning its electric motor does a lot of the legwork on urban roads, but its 1.5-litre petrol engine still has a lot of pep at higher speeds.

The Jazz is comfortable and its light steering is ideal for manoeuvring around city streets, but it can feel a little out of its depth at higher speeds, and it isn’t all that fun to drive – the rival Seat Ibiza is miles ahead in that regard. On the plus side, it’s really spacious for a small car and its lofty driving position gives you that SUV feel, although it does sit at a higher price point than other small car rivals.

We couldn’t mention the Suzuki Swace without also discussing its sister car, the Toyota Corolla Touring Sports. This version features a larger 2.0-litre petrol engine and electric motor, with low-speed urban driving benefitting particularly, much like the other cars on this list, from its hybrid system.

With enough legroom to beat even the huge Skoda Octavia Estate, the Corolla Touring Sports stands out from other estate cars, offering a spacious, upmarket interior and an exceedingly comfortable driving experience. By plumping for the 2.0-litre engine over the entry-level 1.8-litre option, you do sacrifice a bit of boot space, but there’s still 581 litres on offer, which is plenty for some holiday luggage or a couple of pushchairs.

If you’re looking for a small SUV that has decent performance and is cheap to run, then this previous-generation Hyundai Kona is a fine choice – arriving with a thoroughly respectable score of 63.7mpg in the town portion of our tests.

While acceleration isn’t the fastest – it completes 0-62mph in 11.2sec – and the rear passenger space leaves a lot to be desired, it offers a generous amount of kit as standard, and it has a decent infotainment system, although some rivals, like the Seat Arona, are much more impressive.
