The official MPG figures published in sales brochures can tempt you into buying a particular car, but those results are often misleading. Fortunately, What Car?'s True MPG tests reveal what sort of fuel economy you can expect in the real world.

To ensure accuracy and repeatability, we use strictly controlled laboratory conditions, but the tests are based on a real-world route that takes in town, rural and motorway driving.

The results reflect what's achievable if you’re driving gently and sticking to speed limits but aren’t resorting to any unrealistically slow acceleration or special 'hypermiling' techniques.

Today, we're looking at the most efficient cars with 1.0-litre petrol engines. These engines are perfect if you're a new driver, if you don't cover many miles in a year or if you just want to downsize and reduce your running costs. And don't go thinking that they exist only in the smallest models, because our top 10 includes family cars and small hatchbacks as well as city cars.


The 10 most efficient cars with 1.0-litre engines

10. Volkswagen Golf 1.0 TSI 110

Ask 10 people to name a family car and chances are most of them will mention the Volkswagen Golf. It's consistently among the most popular new cars sold in the UK, and with good reason: with such a wide range of engines and versions on offer, there's a model to suit everyone. It's also brilliant to drive, competitively priced and frugal in 1.0-litre turbo petrol form.
