New power upgrades increase output and torque for both models

Ford has released official Mountune power upgrades for its Focus and Fiesta ST models.

Costing from £1225 for the Focus ST upgrade and £599 for the Fiesta ST, and taking under 90 minutes to install, the upgrades significantly improve power and torque on both models.

The Focus ST upgrade - which includes a cast alloy inlet duct, high-flow air filter and a larger intercooler - boosts power from the 2.0-litre EcoBoost engine to 271bhp, while torque is improved to 295 lb ft. The upgraded car can sprint from 0-62mph in less than 6.0sec, more than half a second faster than the standard Focus ST.

Upgrades for the Fiesta ST - based around a remodelled air box with a new secondary inlet duct - improve power to 212bhp and torque to 236 lb ft. Sprint time for 0-62mph falls to 6.7seco, compared to 6.9sec on the standard car.

Both upgrades can be applied from 120 Ford-appointed Mountune dealers. 

Our Verdict

Ford Fiesta ST
Can the Fiesta ST be one of the great fast Fords?

The UK's most popular hatchback gets the hot ‘ST’ treatment, and is all the better for it. Little else can match it for the money

As both upgrades are covered by Ford's Warrenty they seem a 'no brainer'.

"based around a remodelled air box with a new secondary inlet duct "

So that's £600 for a new air box, duct and fitting. sounds a bit expensive

Also, something else must be done as replacing those 2 parts wouldn't give another 30 odd horsepower

 £16,995 Fiesta ST from 179bhp to 212bhp, thanks to an ECU tweak and a reworked air intake, including a secondary inlet duct and high-flow filter.

It’s worth noting the improved figure is developed during the Fiesta ST’s temporary overboost period under full-throttle
