Currently reading: Ford Focus RS Mountune performance kit boosts power to 370bhp
Torque is up to 376lb ft; kit upgrades cost £899 and can be fitted in just an hour and a half

Mountune has produced a performance upgrade kit for the Ford Focus RS that increases its power output to 370bhp and torque to 376lb ft.

That’s a gain of 25bhp and 52lb ft of torque for the car’s turbocharged 2.3-litre engine, shortening its 0-62mph sprint time to 4.5sec – two tenths of a second faster than before.

This brings the RS into close contention with the more expensive Mercedes-AMG A45, which completes the same the sprint just three tenths quicker but slots into the class above, costing from £40,000.

Mountune’s RS kit includes a high-performance air filter, bespoke alloy crossover duct with high-performance silicone hoses, an upgraded air recirculation valve and revised software tuning for the car's ECU. 

Fitment of the parts can be carried out by any Mountune-approved Ford dealer. The job is said to take just an hour and a half, for a total cost of £899. Therefore, added to the Focus’s £31,000 entry-level price, a Mountune-spec RS will cost £31,899.

The kit is fully approved by Ford Performance, with the division’s Autocar award-winning engineering manager, Tyrone Johnson, saying: “Ford has a proud history of working with Mountune to unleash even more power from our hot hatchbacks for dedicated performance enthusiasts. Boosting power to 370bhp launches the already class-leading Focus RS even further ahead of the field.”

Mountune offered its first upgrades for the Focus RS back in May, with lighter wheels, a big brake kit and Quaife differential being the key items on the lengthy list of parts.

Is Ford’s AWD mega-hatch as special as we first thought? And can the Focus RS beat stiff competition from the Volkswagen Golf R and Mercedes-AMG A45?

That added performance for mere £899

Appears well worth it. Probably most buying now will also buy that kit.

STILL not ALL Car it could be,it doesn't need gobs of power or torque,why no stripped out light weight version like Renault have done?
