Ford has introduced a Mountune upgrade package for the Fiesta ST and Focus ST.
The Fiesta ST is equipped with a new air box (with a secondary inlet), a high-flow air filter and an optimized ECU. These changes enable the 1.6-liter EcoBoost engine to produce 215 HP (158 kW) and 320 Nm (236 lb-ft) of torque. This enables the car to accelerate from 0-100 km/h in 6.7 seconds which is 0.2 seconds faster than the standard model.
Likewise, the Focus ST is equipped with a cast alloy inlet duct, a larger alloy intercooler, a high-flow air filter and an optimized ECU. Thanks to the modifications, the turbocharged 2.0-liter Ecoboost engine produces 275 HP (202 kW) and 400 Nm (295 lb-ft) of torque. The extra oomph enables the model to run from 0-100 km/h in less than six seconds.
The Mountune upgrade can be installed in less than 90 minutes and estimated pricing starts at $ 915 for the Fiesta ST and $ 1870 for the Focus ST.
