What are the running costs?

No surprises here that the Fiesta is cheap to run – both in terms of fuelling and servicing and maintenance. With a range of economical petrol engines, some of which feature mild-hybrid technology, the lack of a diesel version shouldn’t be too much of a loss. Insurance groups range from 5E up to 15E – the 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 high-tech engines.

Mild hybrid technology was introduced in 2020. and is now included with both the 125 and 155hp engines. Badged Ecoboost Hybrid, this occasionally uses electrical assistance to help the petrol engine along. The driver will spot a cog symbol that appears when accelerating under the engine’s power and a battery logo when you are not, typically when using the regenerative braking and start-stop.

All Fiesta models remain relatively cheap to run when it comes to fuel economy and mpg figures. The entry-level 1.1-litre 75hp needs to be worked harder than most of the other engines, we suspect it’ll be more difficult to reach these figures consistently. Opt for one of the 1.0-litre engines and you also get cylinder deactivation, switching off one of the three cylinders when coasting or cruising without requiring much of the engine’s power to further conserve fuel.

The most economical engine in the range goes to the 125hp Ecoboost Hybrid, and even the more powerful 155hp engine matches the lower-powered 95hp engine’s figures. During our time of testing with the 125hp Ecoboost Hybrid, we saw an indicated 49mpg after a long motorway journey, before creeping down to 48.7mpg in town.

You can view the full range of Ford Fiesta options and specifications here, but as a rule only the 1.0 EcoBoost 125 automatic drops below 50mpg officially, and it’s the only one to exceed 130g/km of CO2 as well. Everything else delivers between 52.3 and 56.5mpg, and 114-124g/km CO2.

Servicing and warranty

There should be no unpleasant surprises when it comes to servicing and maintaining a Fiesta, as Ford parts and labour costs are typically lower than rivals. A number of service packages are also available from main dealers, which further help keep costs in check. You can also get an extended warranty to increase the coverage from the standard three year, 60,000 mile offering.

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


  • Cabin feels of reasonable quality
  • Tried and tested engines and running gear
  • Recent Ford dependability has been above average

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, though it falls short of the standard set by the new Volkswagen Polo 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.
