If you're a new driver, mainly drive in town or are simply looking to keep costs down, then you might be considering a car with a 1.0-litre petrol engine. Such models are usually on the small side, but include family cars and a plenty of small SUVs among their ranks.

Don't think that choosing a car with a 1.0-litre engine means you'll forever be in the slow lane, either. While you're unlikely to be blown away by their performance, these engines are usually turbocharged, meaning you'll find surprisingly nippy acceleration.

Choosing a car with a 1.0-litre engine is a good move if you're looking to cut costs, too – and especially so if you don't fancy a hybrid or electric car. But which models will keep your running costs as low as possible? Read on for the answer, based on the results of our unique True MPG tests.
