All-New Ford Focus ST - Responsive power delivery

A new generation of Ford’s 2.3-litre EcoBoost all-aluminium engine is the most powerful ever offered for a Focus ST. Using advanced turbocharging technology to deliver 280PS power at 5,500rpm and 420Nm of torque from 3,000rpm to 4,000rpm, it is also the most free-revving Focus ST engine ever, and supports anticipated 0-62mph acceleration in less than six seconds.

Engine response is enhanced using a low-inertia twin-scroll turbocharger, which scavenges exhaust gas energy more effectively using separated channels to minimise interference between gas pulses. An electronically actuated waste-gate allows closer control of boost pressures for optimised engine performance. In addition, a unique exhaust system that reduces back pressure, bespoke air intake system and optimised intercooler further improve breathing.

Innovative anti-lag technology developed for the Ford GT supercar and F-150 Raptor pick-up is introduced to the Focus ST, for immediate power delivery in Sport and Track drive modes. Anti‑lag keeps the throttle open when the driver lifts off the accelerator pedal, alleviating the reversal of air flow from the turbocharger to maintain compressor wheel speed and enabling boost pressure to build faster on demand.

Ford’s 190PS 2.0-litre EcoBlue engine is the most powerful diesel engine ever offered for a Ford Focus model, delivering peak power at 3,500rpm and 400Nm of torque between 2,000rpm and 3,000rpm – and 360Nm from 1,500rpm – for immediate and linear acceleration.

The diesel variant features a low-inertia variable geometry turbocharger; steel pistons for less expansion when hot; and an integrated intake system with innovative mirror-image porting for optimised combustion help to deliver a diesel powertrain that produces 10 per cent more power and more than twice as much torque as the 2.0‑litre Duratec ST petrol engine in the first generation Focus ST170.

The Focus ST’s six-speed manual transmission enables more urgent gear-changes and provides a sportier feel with a shift-throw reduction of seven per cent compared with the standard all-new Focus. Ford’s new rev-matching technology that debuted on the new Ford Mustang is also introduced as part of an optional Performance Pack for 2.3-litre EcoBoost manual models.

Delivering smoother, faster downshifts, the technology is accompanied by a shift indicator light, and uses the engine’s electronic control system to briefly “blip” the throttle as the driver engages a lower gear – matching the engine rotation speed to that of the gear that is being selected.

Rev-matching enables less-experienced performance drivers to benefit from the seamless, momentum-maintaining gearshifts delivered by the “heel-and-toe” driving technique, while also enabling experienced performance drivers to deactivate the system if they prefer.

Gear differentiation on the new seven-speed variant of Ford’s automatic transmission is optimised for performance, and Adaptive Shift Scheduling – which assesses individual driving styles to optimise gearshift timings – is enhanced to offer more flexibility and the ability to differentiate between road and track use. Drivers can select gears manually using steering wheel-mounted paddle-shifters.

“The EcoBoost petrol and EcoBlue diesel powertrains have unique characters, but are equally charismatic,” Roeks said. “The Focus ST’s sporty ‘pops and bangs’ soundtrack perfectly matches the car’s feisty performance and is an essential part of the ST experience.”
