Top 20 most fuel-efficient cars in the UK right now

Fuel prices are rising at their fastest rate since the turn of the millennium.

Figures from the RAC show that petrol and diesel prices leapt more in May 2018 than in any other month in the last 18 years, leaving pump prices at their highest in almost four years.

Annoyingly, fuel is a requirement for every car. There’s no way around it and every motorist has little choice but to pay whatever number is displayed on the pump – or do they?

Fuel cards mean that drivers aren’t hit as hard at the pumps, offering savings of up to 10p per litre on motorways.

Meanwhile, advances in engine technology have also optimised engines to ensure the fuel economy returned by today’s petrol and diesel cars has never been stronger.

But which cars offer the highest combined mpg right now?

We’re ignoring hybrids and other electric tinkery and focusing on pure internal combustion. Spoiler alert: the first 17 cars in this list are diesels, but the dominance of oil burners in a list that ranks mpg shouldn’t be surprising.

Anyway, here we go…
