The cost of running a car is a growing burden on UK motorists so we’ve complied a list of the most economical cars on sale to help. If you want the best possible mpg and tax-friendly CO2 emissions, you’ve come to the right place.
Identifying the most economical car to run isn’t straightforward. There are so many variables to consider, a car that proves cheap to run for one motorist might not deliver the goods for another.
That’s why we’re going back to basic here, our top 10 most economical cars are the most fuel-efficient cars on sale in the UK according to the official combined cycle mpg tests.
We’ve excluded teetotal full electric cars from the list and hybrid cars that rarely return anything close their official economy figures in real-world driving. Instead, we’ve concentrated on conventionally engined cars. You’ll still do well to replicate the official figures on the road but the mpg numbers do provide a level playing field for comparison purposes.
1. Peugeot 308 Blue HDi - 91.1mpg
2. Volkswagen Golf BlueMotion - 88.3mpg
3. Hyundai i20 1.1 CRDi - 88.3mpg
4. Kia Rio 1.1 CRDi - 88.3mpg
5. Renaulr Clio 1.5 dCi - 88.3mpg
6. Skoda Octavia Greenline - 88.3mpg
7. Ford Fiesta Econetic - 85.6mpg
8. Vauxhall Corsa 1.3 CDTi - 85.6mpg
Generally, small diesel cars have the highest mpg, but there is no point in going for great fuel economy if the car doesn't fit in with your life. While a tiny city car will be very efficient on urban roads, its small dimensions often mean a cramped interior and limited boot size, which won’t be much use to a family of five.
A diesel engine won't run efficiently if you only do short, in-town journeys, yet a small petrol engine may have to be revved hard, which could make motorway trips noisy. Also, diesel cars usually are more expensive than their petrol equivalents and are more costly to fill up. So if you don't cover long distances, a petrol car could make more financial sense.
You need to think carefully about which car will suit your needs best.
The cut-off point for our most economical cars list is an astonishing combined cycle return of 85.6mpg. Below that sit a cluster of fantastic cars that average over 80mpg but didn't quite make it into the fuel efficiency hall of fame. Any one of them should still be seriously cheap to run. Here's the best of the rest...
