The most fuel-efficient petrol cars you can buy

Sales of new diesel cars remain in freefall – already down another 20 per cent in 2019 – following the Government’s efforts to encourage motorists to ditch them in favour of cleaner, more eco-friendly vehicles.

As a result, registrations of petrol cars have moved higher, increasing by almost six per cent so far this year.

But it’s a well-known fact that diesels offer the better fuel economy of the two, meaning high-mileage motorists might still be better off with an oil burner over a motor powered with unleaded.

However, up-to-date real-world fuel economy measurements have listed the 10 petrol cars with the best miles per gallon figures that might encourage mile-munchers to make the switch.

Green petrol: These real-world fuel economy figures reveal which new unleaded models are most frugal Dacia's Sandero represents affordable driving when it comes to new cars. For less than £7k you can have a zero-mile motor that returns almost 53mpg Seat's Leon is a family hatchback that can be relatively affordable to run, if you go for the 1.0-litre model Kia's Picanto is robust little city car. Fitted with the three-cylinder 1.0-litre unit, it's cheap to run too The VW Up features twice in this list. The first example is the turbocharged 89bhp model, which we think is the better of the two options thanks to its higher performance Buy a 1.0-litre Seat Ibiza and you'll have fairly low fuel bills. While the True MPG stat is 6mpg short of the official figure, it proves that a large supermini can be a low-cost runner The Suzuki Baleno is a little known family hatchback, but it might be one to consider when you think of the fuel returns on the 1.0-litre example Skoda's Citigo is essentially a less cool VW Up. Fitted with the - frankly weedy - 59bhp 1.0-litre three-cylinder engine, it will do over 55mpg The second Up in our list is a non-turbo 75bhp example. It doesn't have the refinement or acceleration of the previous model in the list, but does have better fuel returns Another cheap runner is the Suzuki Celerio. You can get one for less than £7,000 new and it will return almost 58mpg in the real world The most efficient petrol car tested by What Car? so far is an SUV. Well, a small one. It's the Suzuki Ignis, which can almost hit 60mph with this particular engine under the bonnet The most efficient petrol car tested by What Car? so far is an SUV. Well, a small one.

The SHVS version of the Ignis, which is front rather than four-wheel drive, is the most efficient petrol-powered car What Car? has tested yet.

It’s what’s called a ‘mild hybrid’. That means it has a small electric motor to supplement the 1.2-litre petrol engine under the bonnet.

The compact crossover achieves almost 60mpg in the True MPG test. 

And even if you wanted a model with the extra security of four-wheel drive, the figure drops to just 53.3mpg.
