Ford's all-new 1.5-litre EcoBoost engine uses turbocharging, high-pressure fuel injection, Twin-independent Variable Cam Timing and a three-cylinder architecture to deliver 200 PS at 6,000 rpm, and 290 Nm of torque from 1,600 to 4,000 rpm.

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.

The Fiesta ST's 1.5-litre EcoBoost engine features Ford's industry-first cylinder deactivation system for a three-cylinder engine - first announced for the 1.0-litre EcoBoost engine - to further improve fuel efficiency for Ford Fiesta ST customers without affecting performance.

The technology automatically stops 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. Active exhaust valve technology amplifies the uniquely exhilarating and naturally sporty three-cylinder engine sound to enhance the driving experience.

The all-new Fiesta ST delivers 6.0 l/100 km (47.1 mpg) fuel efficiency and 136 g/km CO2 emissions, and also features gas particulate filter technology that reduces soot emissions.
