Fuel economy

Petrol engines 34.4 - 55.4 mpg
Diesel engines 50.4 - 64.2 mpg
  • Frugal petrol and diesel engines
  • Cheap servicing
  • Hybrid version expected in the future

Without a hybrid or electric version in the line-up, the running costs of the Focus will take a hit when compared with rivals featuring a more versatile line-up – such as the Volkswagen Golf. However, Ford is well known for cheap parts and servicing.

If you’re after the lowest running costs from a petrol-powered Ford Focus then your best bet is either the 100hp 1.0-litre model on 16-inch wheels, which claims an average of 60.1mpg in manual form.

One thing worth bearing in mind is that, if you opt for the eight-speed automatic, the 125hp engine is reputed to average 50.4mpg – which is 1mpg less than the 182hp 1.5-litre version in manual form.

The 95hp 1.5-litre EcoBlue diesel engine returns a claimed average of 80.7mpg, as does the punchier 120hp version (in manual gearbox, 16-inch wheel guise). Opt for the automatic gearbox on the latter, however, and this drops to 67.3mpg. 

The 2.3-litre EcoBoost in the ST claims to achieve 35.7mpg, while the 2.0-litre diesel claims to achieve a higher 58.8mpg. Figures for the automatic gearbox are yet to be published.

Ford Focus servicing and maintenance

There should be no unpleasant surprises when it comes to servicing and maintaining a Focus, as Ford parts and labour costs are typically low. A number of service packages are also available from main dealers, which further help keep costs in check.

Green credentials

  • No hybrid option – petrol and diesel only
  • Cleanest petrols are 100hp and 125hp EcoBoost
  • 95hp EcoBlue dips below 100g/km of CO2

With no confirmed hybrids models for the Focus, the cleanest, greenest version you can buy – at least as far as CO2 goes – is the 91hp 1.5-litre diesel, which produces just 96g/km. This is closely followed by the 120hp 1.5-litre variant (with 16-inch wheels and a manual gearbox) that emits just 2g/km more CO2, despite boasting an extra 25hp.

For the petrol with the lowest CO2, head for the 100hp or 125hp 1.0-litre versions on 16-inch wheels and with the six-speed manual; both produce 107g/km of CO2. Opt for the 125hp 1.0-litre with the automatic gearbox, however, and this leaps up to 126g/km.

It’s no surprise the Focus ST and its 2.3-litre petrol is currently the highest emitting engine when it comes to CO2, with it rated at 179g/km. The 2.0-litre EcoBlue diesel is far more friendly, with a rating of 125g/km. Combine this rating with the lower list price and higher fuel economy figure and this Focus ST makes more sense as a company car proposition than the petrol.

Ford Focus hybrid

Ford has made all of its EcoBoost petrol engines hybrid compatible meaning one should be on the way. However, so far, we’ve seen precious little information as to when this might be.

Reliability

  • All-new C2 platform means there’s little to go on
  • New car has had some recalls
  • Previous car had only one recall

As the fourth-generation Ford Focus sits on a brand-new C2 platform it’s hard to get an accurate read on how reliable it will be, especially with all the all extra gadgets now available.

In 2020, it received two recalls. The first is relating to a potential fault causing the rear doors to open when the rear windows are lowered. And the other, is a potential electrical gremlin. If buying a used Focus, it's worthwhile making sure these potential issues have been rectified.

The previous Ford Focus was very reliable, and, despite being sold from 2011 through to 2018, only had one recall regarding an airbag fault. Exceptionally good going for a car built in such huge numbers.
