POWER-BOOSTING MOUNTUNE UPGRADES FOR FOCUS RS, FOCUS ST AND FIESTA ST ARE NOW AVAILABLE AT HILLS FORD KIDDERMINSTER AND MALVERN

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.

• Mountune Focus ST delivers 275 PS –10 PS more than a Porsche Boxster for £15,000 less – races 0-100 km/h (0-62 mph) in less than 6 seconds
• Mountune Fiesta ST delivers 215 PS and springs 0-100 km/h (0-62mph) in 6.7 seconds – outsprinting Mercedes-Benz SLK 200 AMG Sport

Official upgrades can be fitted in 90 minutes or less and are covered by Ford warranty; available at Hills Ford costing from £1,399 for Focus and £699 for Fiesta – each model still costs less than standard rivals the Volkswagen Golf GTi, and the Peugeot 208 GTi and Renaultsport Clio 200

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.

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.

Once upgraded power increases to 275PS at 5500rpm and torque is raised to 400Nm at 2,750rpm.

The upgrade will produce performance returns of 0-60mph in 5.7 seconds and drops the 31-62mph in-gear time to 4.9 seconds - 0.8 seconds quicker than in standard form. Mountune have tested the upgrades on British B roads and on numerous laps of the famous Nürburgring Nordschleife.

This upgrade can be fitted to any model year of Focus ST, new or used, and has a minimum 12 months/12,000-mile warranty on parts supplied against manufacturing defects and is the only performance upgrade that will not affect your manufacturer base vehicle warranty.
