The new Ford Fiesta ST will produce 200PS but also deliver 58mpg, along with CO2 emissions of just 114g/km.
An all-new three-cylinder, 1.5-litre EcoBoost engine features cylinder deactivation, as a result of a project supported by the UK’s Advanced Propulsion Centre.
With its global public debut at the Geneva Motor Show, the next‑generation Fiesta ST will deliver 200PS, 290Nm of torque and anticipated 0‑62mph acceleration in 6.7sec.
The third generation of Fiesta ST will be the first ever Ford Performance model powered by a three-cylinder engine, and the first Fiesta 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.
Drive Modes will also adjust Fiesta ST’s Electronic Sound Enhancement (ESE) technology and active exhaust noise control valve to deliver an even more satisfying driving experience. The technologies amplify the naturally sporty sound of the new 1.5-litre EcoBoost engine that also features Ford’s industry-first cylinder deactivation system for a three-cylinder engine, for further reduced CO2 emissions of an anticipated 114g/km.
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.
All-new 1-5-litre EcoBoost engine
Part of Ford’s EcoBoost range of petrol engines that also includes the multi-award-winning 1.0‑litre EcoBoost, the all-new 1.5-litre EcoBoost engine uses technology including turbocharging, high-pressure fuel injection and Twin-independent Variable Cam Timing to deliver optimised performance and fuel efficiency.
The engine’s three-cylinder architecture delivers naturally high torque at low rpm. Performance is further boosted by a new turbocharger that uses an optimised turbine design to build boost pressure faster and minimise lag for a more responsive and fun driving experience.
A new combination of port fuel injection and direct fuel injection technology helps deliver high power and responsiveness alongside reduced CO2 emissions, with a particular increase in fuel efficiency under light engine loads.
Ford’s new cylinder deactivation technology – first announced for the 1.0-litre EcoBoost engine and a world first for a three-cylinder engine – will further improve fuel efficiency for Fiesta ST customers without affecting performance by automatically stopping fuel delivery and valve operation for one of the engine’s cylinders in conditions where full capacity is not needed, such as when coasting or cruising with light demand on the engine. The technology can disengage or re-engage one cylinder in 14 milliseconds – 20 times faster than the blink of an eye – to seamlessly deliver full performance on demand.
The all-aluminium engine also 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. Gas particulate filter technology that reduces soot emissions will also feature.
New Drive Modes
Selectable Drive Modes add even more versatility for the next generation Fiesta ST, enabling drivers to optimise the driving experience to suit scenarios from school run to the race track:
The Ford Performance-tuned chassis will be supported by enhanced Torque Vectoring Control technology that improves road holding and reduces understeer by applying brake force to the inside front wheel when cornering. Three-mode ESC will enable drivers to choose between full system intervention; wide-slip mode with limited intervention; and full system de-activation.
