Ford Fiesta ST review – MPG and running costs

Running costs shouldn’t be too high, but keep an eye on those Michelin Pilot Sport 4 tyres

Manufacturers have several reasons for downsizing engines, from fuel economy to economies of scale, but if it’s the former then the new engine gains nothing over its predecessor. In fact, it loses slightly, at 47.1mpg combined compared to 47.9mpg for the old four-pot.

Economy in the real world is unlikely to be better, either – our old long-term Fiesta ST had averaged 38.1mpg during our tenure, and in mixed driving we saw high-30s in the latest model, too. If you opt to take your ST on a track – a not unreasonable scenario, given how entertaining the new car is when freed from the constraints of road driving – then you’ll need to keep a beady eye on the gauge, too, as the car we tried burned through more than half a tank in a few short sessions around the Goodwood circuit. We’d estimate economy in the low teens in such a situation.

It’s difficult to estimate other costs at this stage, though all STs wear Michelin Pilot Sport 4 tyres, and burning through a set of those will cost around £120 per corner (delivered from Blackcircles) for the cars on 205/45 R17s, and about £150 a corner for the ST-3 on its 205/40 R18 wheel and tyre set-up.

The ST’s 136g/km of CO2 means a first-year VED rate of £205, and then £140 a year thereafter. In terms of BIK for those lucky enough to have an ST as a company car, all three models sit in the 28 per cent bracket.
