Ford‘s critically acclaimed Focus ST and Fiesta ST hot hatches just got hotter with the introduction of official Mountune upgrades.
The packages are developed by race engine and road-car performance specialist Mountune, and boost output from the Focus ST’s 2.0-litre EcoBoost engine to 275 PS; 10 PS more than from a Porsche Boxster that, at £38,237, costs £15,000 more.
Even the Ford Sierra Cosworth RS500 would be left with a rear view of the Mountune-upgraded Focus ST, which can sprint from 0-100 km/h (0-62 mph) in less than 6 seconds – more than half second faster than the standard Focus ST.
Ford is also offering an official Mountune upgrade for the Fiesta ST, which will increase the maximum power available to 215 PS*, enabling acceleration of 0-100 km/h (0-62 mph) in 6.7 seconds, compared with 6.9 seconds on the factory model – faster than a £35,865 Mercedes-Benz SLK 200 AMG Sport 7G-Tronic Plus.
The Mountune upgrades boost both Focus ST and Fiesta ST in-gear acceleration. Peak Focus ST torque boosted to 400 Nm improves 50-100 km/h (31-62 mph) acceleration in fourth gear by 0.8 seconds to 4.9 seconds; peak Fiesta ST torque boosted to 320 Nm* improves 50-100 km/h (31-62 mph) acceleration in fourth gear by 0.7 seconds to 5.7 seconds.
Any Mountune-appointed Ford dealer will be able to fit the upgrade quickly – less than 60 minutes for the Fiesta ST, and less than 90 minutes for the Focus ST. Both are fully compatible with the Ford warranty, meaning Mountune modified vehicles continue to be covered against mechanical failure for three years or 60,000 miles from the original date of purchase.
“Ford’s ST models already deliver blistering performance – for these Mountune upgrades we have squeezed out every last drop of fun and served it on a plate to the fans that are as passionate about performance as we are,” said Tyrone Johnson, Ford Team RS engineering manager.
The Focus ST Mountune upgrade is available in silver and in black and includes a cast alloy inlet duct, high-flow air filter element, larger alloy intercooler and unique calibration. The Fiesta ST version has a re-modelled air box base with secondary inlet duct, a high-flow filter element and unique calibration.
The Focus ST Mountune upgrade costs £1,225 for silver, £1,275 for black to still come in less than the standard Volkswagen Golf GTi. The Fiesta ST Mountune upgrade costs £599**, to sell for less than both the standard Peugeot 208 GTi and Renaultsport Clio 200 Turbo models.
“We worked hand-in-hand with Ford engineers to deliver what we believe is the best bang-for-buck value on the market,” said David Moore, marketing manager, Mountune.
The Fiesta ST and Focus ST Mountune upgrades will be available in selected European markets from September.
