Three cylinder power for next Fiesta ST

1994

Ford’s next Fiesta ST hot hatch will be powered by a three cylinder engine.

Shown for the first time ahead of its international debut at next month’s Geneva Motor Show, the next‑generation Fiesta ST will deliver 147kW of power and 290Nm of torque , with an estimated 0‑100km/h time of 6.7 seconds.

The current ST produces 134kW and 240Nm from its turbo 1.6-litre four cylinder engine.

A new combination of port fuel injection and direct fuel injection technology helps deliver high power and responsiveness alongside reduced CO2 emissions, with an increase in fuel efficiency under light engine loads – thanks to cylinder deactivation which turns into a two cylinder unit when cruising.

Ford’s new cylinder deactivation technology – a world first for a three-cylinder engine – takes just 14 milliseconds or 20 times faster than the blink of an eye to change between two and three cylinder mode seamlessly delivering full power.

The all-aluminium engine features an integrated exhaust manifold that improves efficiency by helping the engine reach optimal temperatures faster and delivers torque more rapidly by minimising the distance exhaust gasses travel between cylinders and turbocharger.

Triple treat . . . the wraps come off Ford’s new Fiesta ST.

Gas particulate filter technology that reduces soot emissions will also feature.

The third generation Fiesta ST will be the first ever Ford Performance vehicle to be powered by a three-cylinder engine.

It will also be the first ST to feature selectable Drive Modes – enabling engine, steering and stability controls to be configured to Normal, Sport and Track settings for an optimised fun-to-drive experience in conditions from motorways to track days.

The system also includes Electronic Sound Enhancement (ESE) technology to deliver an even more satisfying driving experience.

  • In Normal mode, engine mapping, traction control, electronic stability control (ESC), ESE, exhaust sound and electronic power assisted steering (EPAS) are configured to deliver natural responsiveness and a connected feel
  • In Sport mode, engine mapping and throttle pedal response are sharpened, and EPAS settings adjusted to deliver more feedback and finer control for fast road driving. The active noise control valve opens and ESE is adjusted to intensify the sporty exhaust note and engine noise within the cabin
  • In Track mode, all vehicle dynamics features are tuned for the fastest possible lap times, traction control is disabled and ESC interventions are set to wide-slip mode for hard circuit driving

Torque Vectoring Control is standard and helps to reduces understeer by applying brake force to the inside front wheel when cornering.

Available from launch in early 2018 in both three-door and five-door body styles, the next generation Fiesta ST will be offered with a greater variety of interior trim and personalisation options than ever before, with bold and distinctive exterior styling that includes a unique race-car-inspired mesh grille and exclusive 18 inch alloys.

“Our next generation Fiesta ST is true to the philosophy of delivering cutting-edge technology to enhance every facet of the responsive Ford Performance chassis and powertrain,” said Joe Bakaj, vice president, Product Development, Ford of Europe.

“With selectable Drive Modes and an all-new EcoBoost engine delivering an unprecedented combination of performance and fuel-efficiency, the new model will deliver the most versatile, fun, engaging and rewarding Fiesta ST driving experience yet.”
