Priced at £429 ($556/€481) in the UK for a DIY installation, or £350 ($454/€392) to have them fit it to your car at their headquarters in Brentwood, it includes an OBDII flashing cable, dongle, performance calibration and, of course, the ‘Mountune’ badge.
The result is 20PS (20hp / 15kW) and 50Nm (37lb-ft) of torque more than the stock model, whose 2.0-liter TDCi engine produces 185PS (182hp / 136kW) and 400Nm (295lb-ft) of torque. The 0 to 60 mph (0-96 km/h) acceleration is now completed in 7.4 seconds, 0.7 seconds quicker than the stock car, and top speed is maintained at 135 mph (217 km/h).
“The standard Focus ST diesel is a great base car, but with the m460D kit installed, we’ve been able to make it smoother, quicker and generally even more fun to drive”, said Mountune’s Global Brand Manager, David Moore.
While Mountune continues to drop upgrades for the current Focus ST, Ford is working on the new generation. Details about the diesel version are quite scarce at the moment, but it’s believed to live on, despite the sales decline of oil burners.
As for the petrol model, it could make use of the turbocharged 2.3-liter EcoBoost four-cylinder that powers the entry-level Mustang, though in the hot hatch it will probably be detuned to around 250PS (246hp / 184kW).
The new Ford Focus ST should arrive next year, followed by the next-gen Focus RS in 2020.
