Ford Fiesta review - MPG, CO2 and Running Costs

Small petrol and diesel engines mean the Ford Fiesta is really cheap to run

Part of the magic of cars in the supermini class is that they can be fun to drive, more so than some much more expensive cars, without being pricey to run. The new Ford Fiesta is no exception to that rule, and its range of small-capacity petrol and diesel engines are very frugal.

It’s not just about fuel economy, as purchase price and even the cost of fuel plays a big part in how cheap a car is to run. For that reason we expect that most buyers will gravitate towards the petrol 1.0-litre EcoBoost with 94bhp. It emits just 94g/km of CO2 and returns up to 55.4mpg, which is competitive in its class - most 1.0-litre turbocharged petrols, such as the ones in the Skoda Fabia, SEAT Ibiza and Suzuki Swift will produce very similar figures.

The 123bhp version of the EcoBoost engine returns the same economy figure, and emits just 2g/km more CO2, while the 138bhp 1.0 emits 107g/km and returns 51.4mpg. The 99bhp 1.0 EcoBoost version is only offered as a six-speed automatic and, as such, suffers from a dip in economy and emission figures - producing up to 130g/km of CO2 and 42.8mpg. We’d avoid it if you can and go for the excellent manual instead.

The 74bhp 1.1-litre naturally-aspirated petrol Fiesta returns 53.3mpg and 102g/km. For some company car buyers the low-emitting diesel model may make sense, as it does return the highest mpg figures of the range. The lower-powered 84bhp 1.5-litre TDCi is the ultimate choice for economy, thanks to figures of 65.7mpg and 92g/km of CO2. However, if you’re a private buyer it’s worth keeping in mind that you’ll need to cover around 80,000 miles before the fuel economy gains offset the car’s extra purchase price.

Insurance groups

Entry-level Fiesta Trend cars with the 74bhp 1.1-litre petrol are the cheapest to insure, sitting in insurance group 5E. Our choice, the 94bhp EcoBoost model in Titanium trim, sits in group 10E - that should make it very affordable for most drivers to insure. 

The 138bhp EcoBoost version in ST-Line specification is only in group 15E, as is the top-spec Fiesta Vignale with the 1.5-litre TDCi diesel. This indicates just how cheap the Fiesta will be to insure. It’s a brilliant choice for drivers of all ages.


Experts tell us that after three years a Ford Fiesta will hold on to an average of 37.2 per cent of its value, which is pretty good for what’s likely to continue being the top-selling car in the UK. Our choice, the 1.0 EcoBoost Zetec, will hold on to 37.9 per cent of its value after three years, while the best-performing model will be a high-spec 138bhp EcoBoost ST Line car. Our experts say that version will hold on to 41.6 per cent of its value over the same period. The new SEAT Ibiza will fare slightly better, keeping hold of around 41.9 per cent after three years.
