Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Fuel economy

Petrol engines 40.4 - 55.4 mpg
Diesel engines 54.3 - 65.7 mpg
  • Low-cost petrol and diesel engines
  • Cheap to insure, maintain and service
  • Finance reasonable, no hybrid or electric version

The cheapest Fiesta to run when it comes to fuel bills is the 1.5 diesel, which returns between 55.4 and 60.1mpg on the combined cycle. We doubt you’ll see that sort of economy in the real world, however, because you’ll have to work the motor quite hard to make meaningful progress.

However, most people will be buying petrol. The most economical for sale is the 100hp version of the 1.0-litre. It'll officially do 50.4mpg, and in our own testing it comes pretty close to achieving those figures.

Financing costs generally range from £125 - £150 per month with a 10% deposit for basic Fiestas - rising to around £250 for the most expensive Fiesta, the ST. As the Fiesta grows older, its finance deals become better. So keep a lookout for these deals, like 0% APR on finance, and money off for scrapping your old car.

Insurance groups range from 5E up to 15E - the high-performance Fiesta ST is 28E - so it’s at the cheaper end of the spectrum here too, and fuel economy and tax bills are very low indeed thanks to a recent range of high-tech engines.

Ford has famously favorable servicing and maintenance costs, including fixed-price packages, along with an extensive dealer network.

Green credentials

While the lowest CO2 and fuel economy figures come with the 1.5-litre diesel engine, ranging between 96 and 103g/km for the 85hp version. None of the versions are particularly bad in this respect, with the automatic version of the 1.0-litre EcoBoost 100hp petrol emitting between 125 and 138g/km – still not the end of the world.

Reliability

  • Cabin feels of reasonable quality – better than before, but not near the head of the class 
  • Tried and tested engines and running gear, should translate to reliability 
  • Recent Ford dependability has been above average, but with niggles through being built to a price

Despite being smaller and cheaper, the Ford Fiesta feels as well built as any other Fords, such as the Focus and Mondeo – but it's clearly built to a price.

The quality of the interior especially stands out as being good in your line of sight, but expect the new Volkswagen Polo to move on the game in that regard.

Our owners' reviews don't show any prevailing problems with the previous generation of Fiesta's reliability either - with just one disgruntled owner who appeared to have had a number of issues. This could easily be an isolated incident.

During the car's lifespan, it's only had one recall - a precautionary one regarding a brake servo. If you're buying a used Fiesta, make sure this has been done. It should be noted that 99% will have had the work completed - but it's just worth checking.
