Driving dynamics

Ford’s new sport steering system variable ratio steering rack is designed to increase agility on winding roads yet still inspire the same high-speed confidence. This is achieved by increasing steering sensitivity when cornering but reducing sensitivity when driving in a straight line. The steering wheel can also be turned to almost full lock without the driver needing to remove either hand to change position; providing more control through tight corners and hairpins.

Ford has specially calibrated the electric power-assisted steering (EPAS) system for the all-new Focus ST. The system is able to detect and counter torque steer using a more aggressively pitched version of Ford’s torque steer compensation (TSC). More aggressive tuning of the torque steer compensation allows drivers to accelerate at full throttle yet still find grip on roads with uneven surfaces.

Further enhancements have been made to the all-new Ford Focus ST’s Electronic Stability Programme (ESP) to offer three distinct modes – drivers can turn the ESP on for a tuned version of the system found throughout the Focus range; a reduced or wide-slip mode disables traction control and activates ESP only when absolutely necessary; and finally, ESP can be switched off altogether.

To help tackle corners, the all-new Ford Focus ST is equipped with a tuned version of the Torque Vectoring Control (TVC) found on the all-new Focus. The enhanced TVC applies brake torque to the inner wheel through a corner to reduce under steer.  Meanwhile, cornering Under Steer Control (CUSC) applies torque to create a yaw effect based on the car’s under steer behaviour prior to ESP, both in power-on and power-off conditions.

The suspension setup of the new Focus ST complements the advanced driver assistance features and the specially-developed Goodyear Eagle tyres. Upgraded shock absorbers and springs lower the ST chassis by 10mm compared to other Focus models, giving the performance car a more aggressive stance while the centre of gravity is brought closer to the road, which aids precise cornering.

The rear suspension has also been revised with a number of new parts developed specifically for all-new Focus ST. The uprated suspension knuckles and an all-new anti-roll bar design provide outstanding feedback and control.
