Ford Focus review - MPG, CO2 and running costs

The Focus has great fuel economy, is reasonable to insure and doesn't fare too badly come resale time.

The Ford Focus boasts a range of strong engines that each balance performance and economy well. Ford’s ubiquitous 1.0-litre EcoBoost petrol engine now features mild-hybrid tech and comes in two power outputs, while there's 1.5- and 2.0-litre EcoBlue diesel options. All come with six-speed manual gearboxes as standard and this is invariably the best option for those wanting to maximise economy and minimise CO2 emissions.

The 1.0-litre 123bhp and 153bhp petrol versions are both able to achieve a maximum 55.4mpg, with CO2 emissions from 116g/km. The 1.5-litre 118bhp EcoBlue diesel achieves a claimed 62.8mpg on the combined cycle, while the 2.0-litre unit with 148bhp isn't far behind with 60.1mpg. CO2 Emissions are 119g/km and 125g/km, respectively.

The more powerful 2.3-litre ST petrol model achieves 34.4mpg, although CO2 emissions are much higher at 188g/km. The hot ST diesel with 190bhp still manages 50.4mpg, while emitting 148g/km of CO2.

Any Focus Estate model will trail its five-door hatch slightly on emissions and fuel economy, but this model remains competitive with its rivals on this front.

Insurance groups

The most basic Ford Focus models should be incredibly cheap to insure. Zetec models start at group 11, while ST-Line comes in at a competitive group 13. The most expensive to insure is the ST, which sits much higher in group 34 in its most powerful petrol version; opt for the diesel and it’s group 23. 

Depreciation

The Mk4 Focus has decent residual values of around 42% over three years and 36,000 miles, but the ever-steady VW Golf is still a few points ahead, holding onto an average of just over 45% over the same period.
