What is miles per pound?

Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 47 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Working out Ford Fiesta ST running costs couldn’t be simpler. There’s just one engine, and all of the figures remain the same no matter which trim you go for. Fuel economy is a claimed 47.9mpg on the combined cycle, which is just about possible if you’re gentle with your right foot.

With a 42-litre petrol tank, the theoretical maximum range is 443 miles though we’d expect between 300 and 350 miles in the real world, largely thanks to that addictive exhaust note.

Although not exactly what you’d dub an ‘eco car’, the Ford Fiesta ST emissions aren’t too bothersome. It puffs out 138g/km of carbon dioxide, which means fairly agreeable road tax as well as not being too polluting.

Ford Fiesta ST reliability shouldn’t be much of a concern. The Fiesta has been on sale since 2008 and there haven’t been any major issues. The engine and gearbox in the ST are tried and tested in other products.
