Toyota RAV4 – up to 50.4mpg

Toyota has earned a solid-gold reputation both for its robust build quality and its excellent hybrid engines. The RAV4 combines both strengths into a chunky SUV package, with plenty of passenger space making it easy to fit child seats on the back row, and a boot large enough to swallow pushchairs or suitcases with ease.

To hit those high economy figures, Toyota’s equipped the RAV4 with a petrol-hybrid engine that recharges the battery when slowing down, saving you having to mess with any charging cables. This setup is impressively smooth and includes an automatic gearbox as standard, making it fuss-free to scoot through city traffic.

Citroen C5 Aircross – up to 60.8mpg

Citroen C5 Aircross in blue, driving shot

Citroen has never been afraid to do things a little differently, and the C5 Aircross SUV is another great example. This spacious five-seat SUV has a bold, eye-catching design inside and out, with an elegant dashboard dominated by modern-looking screens. Plus, with three individual rear seats, you can mount three child seats across the rear if needed – even if Isofix points are only fitted on the outer two seats.

To take advantage of fuel economy that can go above 60mpg, you’ll want to consider the C5 Aircross’ 1.5-litre diesel engine. Despite its small capacity, this unit makes 130hp and has a decent helping of torque, so it won’t feel underpowered at motorway speeds. Citroen’s petrol engines are still reasonably efficient and are a better choice for mainly urban drivers, with petrol C5 Aircross models achieving mpg figures in the high 40s. If you have the ability to charge your car at home, Citroen also offers a plug-in hybrid option with mega mpg figures.

Kia Sportage HEV – up to 51.4mpg

Kia Sportage in red

The Kia Sportage has quickly risen from being yet another SUV competitor to one of the best in class. It's spacious and practical inside, as well as easy and satisfying to drive on the open road. The dashboard design is modern with huge screens for infotainment and driver information, but with enough physical controls in the right places to make everything easy to use at a glance. You also have the reassurance of Kia's seven-year factory warranty and the brand's excellent reputation for reliability.

Search the used market for Sportage models and you'll find previous-generation cars with long-legged diesel engines – great if you want lots of range from a full tank. Stick with the newer model, however, and the most affordable versions will be petrol models that can manage more than 40mpg when driven carefully. Our pick is the petrol-hybrid, which is more powerful and can return more than 50mpg. There's also a plug-in-hybrid version with an astonishing 250mpg average if you keep the battery charged up.

Ford Puma – up to 52.3mpg

Ford revived the Puma name for the latest addition to its SUV lineup. This compact model makes a great upgrade for buyers coming from a hatchback thanks to its larger cabin and boot space, which makes it easier if you need to use it for occasional family taxi duties. Other benefits include eye-catching styling and handling that cements Ford’s reputation for building composed cars that are also great fun to drive.

Despite the Puma’s commitment to putting the ‘sport’ into sports utility vehicle, it can achieve impressive fuel economy thanks to its fuel-sipping 1.0-litre EcoBoost petrol engine paired with a mild-hybrid system. The hybrid reduces strain when accelerating and recaptures energy when slowing down, helping the petrol-powered Puma achieve more than 52mpg.

Peugeot 2008 – up to 62.7mpg

Peugeot 2008 in orange, driving shot

If you want a small SUV with more than a dash of style, take a look at the handsome Peugeot 2008. This model features the brand’s latest faceted styling in a compact package. There’s more room inside than you’ll find in a typical hatchback and your eye will immediately be drawn to Peugeot’s unusual i-Cockpit design, which uses an especially small steering wheel to make three-point turns and parallel parking a doddle.

This is also one of the shrinking number of small cars that you can still buy with a diesel engine. It’s worth hunting down, however, if you want low running costs – the 1.5-litre diesel can hit nearly 63mpg, which makes it a great choice for long-distance drivers. City drivers should consider a petrol 2008, which can achieve more than 50mpg in the right conditions.

Skoda Kamiq – up to 53.2mpg

Skoda Kamiq in red, driving shot

If your parking space will only fit a smaller car, but you still need something that majors on practicality, check out the Skoda Kamiq. This dinky SUV is only a foot longer than the Fabia hatchback, but squeezes an impressive amount of passenger space from such a small footprint, allowing adults to fit comfortably in both the front and rear. You also get the tough build quality Skodas have become known for and an ergonomic, easy-to-use dashboard.

While the Kamiq’s engine lineup is petrol only, its relatively small size and low weight means you can still achieve economy figures in excess of 50mpg in cars powered by the 1.0-litre TSI engine. Even when stepping up to the mid-range 110hp engine with Skoda’s smooth-shifting DSG automatic gearbox, economy only falls to around 49mpg, making the Kamiq a frugal and fuss-free way to navigate congested city centres.

Family cars

Volkswagen Golf – up to 62.8mpg

Volkswagen Golf in yellow, driving shot

The Volkswagen Golf is an icon among family cars and has, for decades, offered a compelling combination of decent practicality, premium features and a comfortable, fuss-free driving experience. Inside, you’ll find seating for five adults at a push, with a rear bench comfortably large enough to fit two child seats side-by-side. Hatchback Golfs have a useful square boot that can just about fit a folded pushchair, or go for the Golf Estate if you need even more space.

Like the rest of the Golf, its engine lineup is very sensible. Recent models offer a 2.0-litre diesel with a choice of 115 or 150hp outputs – both can return more than 60mpg with either the manual or automatic gearbox. Petrol Golfs are more common on the used market, however, and these are still decently frugal with most 1.0 and 1.5-litre models returning around 50mpg. You’ll also find super-economical plug-in hybrid options further up the range if you have easy access to a charger.

BMW 3 Series – up to 62.8mpg

BMW 3 Series in silver, driving shot

If you’re after a plush family car with a little more room to stretch out, the BMW 3 Series ticks a lot of boxes. You get the premium materials and upmarket styling you’d expect from a BMW, along with fantastically grippy and agile handling. Rear seat passengers have a generous amount of legroom and there’s enough space to wrangle child seats into position.

BMW’s engines strike an impressive balance between refinement, performance and fuel economy. The efficiency champions are the 318d and 320d diesel models that can average more than 60mpg if you drive gently, while the latter can still sprint from 0-62mph in less than seven seconds. Petrol-powered 318i and 320i models can still return more than 40mpg and might make a better choice if you do mainly urban driving.

Toyota Corolla Touring Sports – up to 62.7mpg

Toyota Corolla Touring Sport in silver, driving shot

Toyota scores another spot on our list once again thanks to its great selection of hybrid cars. The Corolla Touring Sports is the estate version of the Corolla hatchback and adds an even larger boot in exchange for a minimal fuel economy penalty. Inside, you’ll find a neat dashboard design with an easy-to-use layout, decent passenger space, and a sense of toughness you’d expect from a car wearing a Toyota badge.

The ace up the Corolla’s sleeve is its pair of petrol-hybrid engine options. These models only recharge their batteries as the car slows down, saving you the need to fiddle with charging cables. The smaller 1.8-litre hybrid can return more than 62mpg, while the larger and more powerful 2.0-litre version can still muster an impressive 56mpg.

Ford Fiesta – up to 56.5mpg

Ford Fiesta in white, driving shot

For many buyers, the Ford Fiesta is the default small car, which has made it a best seller in the UK for years. It’s easy to see why – the Fiesta blends neat styling, a relatively practical cabin and a super-sharp driving experience into one well-priced package. What’s more, recent Fiestas haven’t grown in size as much as some rivals, clocking in at just over four metres long, so they’re still very easy to live with in congested city streets.

Ford has been fitting Fiestas with 1.0-litre engines for some time now in the pursuit of improved fuel economy, and the most recent versions are more frugal than ever. Thanks to the addition of a mild-hybrid system to recapture energy under braking and reduce engine strain while accelerating, 125hp 1.0-litre mHEV Fiestas can average as much as 56.5mpg.

Toyota Yaris – up to 68.9mpg

Toyota Yaris in red, driving shot

Yet another Toyota makes our list, with the latest Yaris being a fine addition to the brand’s lineup. The most recent version adds some welcome funky styling that previous Yaris models lacked but retains the ultra-frugal hybrid-petrol engine. Unlike many ballooning rivals, the Yaris still measures under four metres long, making it easy to squeeze into tight city parking spots.

Thanks to Toyota’s hybrid know-how, the Yaris can average nearly 69mpg. As an added bonus, the hybrid system is even punchier than before and helps the automatic-only Yaris cover the 0-62mph dash in less than 10 seconds – that’s hardly sports-car-like pace, but it’s substantially faster than the wheezy hybrids of just a few years ago.

Kia Picanto – up to 58.9mpg

Kia Picanto in yellow

The Kia Picanto is so compact, at less than 3.6 metres long, it makes the four-metre Yaris and Fiesta look gargantuan by comparison. You'd scarcely believe the stats if you were sat inside the Picanto, either, because you get a remarkable amount of cabin space within its tiny frame. There's enough room to fit six-footers in the back if you can arrange a compromise with the front-seat occupants, and the car's tall roof means headroom isn't too limited. You'll also find enough cargo room for a few shopping bags with space to spare.

You don't need a lot of grunt to get the little Kia up to speed, so you'll only find small petrol engines under the bonnet. The mpg winner is the entry-level 1.0-litre petrol and this works well if you only take occasional motorway trips. There's not much of an economy penalty for picking the more powerful 1.2-litre petrol or the 1.0-litre turbo engine, however, and both are better picks if you do more regular motorway driving.

Premium cars

BMW 5 Series – up to 58.9mpg

BMW 5 Series in blue, driving shot

Thanks to BMW’s clever engineers, you can now have a large, comfortable and powerful executive saloon with fantastically low fuel bills. The 5 Series offers acres of interior space for passengers to get comfortable in, along with a stylish and feature-packed dashboard. Plus, you get a driving experience that effortlessly blends mile-munching comfort with limpet-like grip to help you feel in full control.

BMW’s 2.0-litre diesel engine in 520d models is the one to choose for low fuel bills, with nearly 59mpg possible if you drive with a light right foot. The diesel is most at home on long motorway journeys but, if you mainly cover your miles in urban environments, don’t discount the 520i petrol options, which can still average more than 45mpg. You may want to consider the pricier but incredibly frugal plug-in hybrids at the top of the range if you have access to a charger.

Mercedes C-Class – up to 58.9mpg

Mercedes C-Class in silver

As a used buy, the Mercedes C-Class offers lots of premium features at a relatively attainable price. You don't need to compromise on the 'Mercedes' experience, either. The cabin is spacious and plush, with big, crisp screens for the infotainment system and driver's dials. Choose the C-Class saloon for that classic Mercedes silhouette, or you can opt for the C-Class Estate, which extends the roofline to give you a handy square cargo area – ideal for flatpack furniture or your four-legged companion.

Urban buyers will find the petrol engines are the most flexible and, despite their plentiful turbocharged power, all non-AMG models can return at least 40mpg. It's the diesel engines that are the real efficiency heroes, however, with average economy firmly in the 50s whether you choose the strong C220d engine or the seriously brawny C300d. There's also a plug-in hybrid with a stratospheric 470mpg average – no, that's not a misprint – but you'll have to top the battery up regularly to actually hit close to that figure.

Audi A6 Avant – up to 48.7mpg

Audi A6 Avant in black, driving shot

Audi has a rich history of building premium-feeling estates, with today’s A6 Avant proudly upholding that tradition. As an executive car, there’s a vast amount of passenger space available and lots of rear legroom – ideal if you’re carrying taller adults. However, it’s in the boot where the A6 Avant really shines, with an enormous load area that’ll swallow bikes, luggage or furniture with ease.

Smooth and powerful turbocharged engines are ubiquitous across the A6 Avant lineup, with the cryptically named 40 TDI diesel weighing in as the efficiency champion. This automatic-only 2.0-litre unit makes a healthy 204hp, allowing it to complete the 0-62mph run in 7.6 seconds but, when driven as economically as possible, can return nearly 49mpg.
