This Mountune program does its power-boosting deeds by way of a handful of new components, including: a cast-allot inlet duct for easier breathing; high-flow sports air filter; larger intercooler for less heat soak on extended drives; and recalibration of the electronic systems. Buyers can opt to have the inlet duct and intercooler in silver or powder coated in black.
As it sits, the UK-spec Focus ST packs a mean wallop at 250 PS (246 horsepower) 360 Nm (265 pound-feet) of torque straight off the showroom floor, but Ford’s Mountune program jumps it to an incredible 275 PS (271 horsepower) and 400 Nm (295 pound-feet) of torque.
The power bump drops the Focus ST’s 0-to-100 km/h (62 mph) time from 6.5 to under 6 seconds. Additionally, the 31 to 62 mph acceleration time drops to just 4.9 seconds — a 0.8-second improvement.
The upgrade only takes about 90 minutes to install on the Focus ST and comes in at £1,225 ($1,852) for the silver components or £1,275 ($1,928) for the powder coated black components. This means a total investment of between £23,200 ($35,080) and £26,770 ($40,480), depending on the level of Focus ST and the Mountune kit chosen.
Unfortunately, there is no mention of this kit ever making it to the U.S. We can hope, right?
