Runs to 62 mph (100 kph) in four and a half seconds.

With so many people lining up to buy the Ford Focus RS, it makes perfect sense that Mountune wants to capitalize on the popularity of the all-wheel-drive hot hatchback by developing a series of upgrades. The first order of business was to upgrade the turbocharged 2.3-liter, four-cylinder EcoBoost engine and they were able to squeeze an extra 25 horsepower (18 kilowatts) and 30 pound-feet (40 newton-meters) of torque.

As a result of the added punch, the Focus RS by Mountune will deliver 375 hp (276 kW) and 376 lb-ft (510 Nm) of torque with the 12-second overboost function active. The power gain has slashed 0.2 seconds from the 0-62 mph (0-100 kph) sprint which now takes just four and a half seconds en route to the same 165 mph (266 kph) top speed.

To achieve these numbers, Mountune has developed a custom air filter, an upgraded air re-circulation valve, optimized software tuning for the engine’s ECU, and a new alloy crossover duct with high-performance silicone hoses. Implementing these changes on a standard Ford Focus RS will take only around 90 minutes at any Mountune-appointed Ford dealer and it will not void the manufacturer’s warranty.

The Mountune power upgrade will soon be available in selected European markets and it will set you back £899 in U.K.
