2018 Ford Fiesta ST is the move to an-all new engine configuration. The 1.6-litre four-cylinder turbo used in the current car is out, replaced by a lightweight, aluminium 1.5-litre three-cylinder turbo.
The new motor produces 197bhp. That’s 17bhp up on the standard output of the current Fiesta ST, but equal to its ‘overboost’ figure. Torque swells from 240Nm to 290Nm, and Ford claims that the new Fiesta ST can crack 0-62mph in 6.7 seconds – two tenths quicker than the current generation model and on par with the ST200. A top speed just above 140mph seems likely.
