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.
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 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.
