Ford uses the name ‘EcoBoost’ to describe their range of turbocharged petrol engines. Engine sizes range from 1.0-litre to 3.5-litres, with between 3 and 6 cylinders. Ford’s EcoBoost engines are available across the Ford range, from mainstream models like the Fiesta and Focus, to high performance models like the Ford Fiesta ST, Focus RS and Mustang.

EcoBoost engines combine direct fuel injection, turbocharging and variable valve timing to allow a smaller engine to reduce fuel consumption by up to 20% over larger engines, but still maintain competitive performance.

Ford’s 1.0-litre EcoBoost petrol engines appeared for the first time in Europe in the Ford Focus in 2012 and were launched at a time when car manufacturers were exploring engine downsizing to improve fuel economy and lower emissions, but maintain the power of a larger engine.

In 2016, Ford’s three cylinder 1.0‑litre EcoBoost engine was voted “Best Engine Under 1.0-litre” at the International Engine of the Year Awards for the fifth time. One in five all-new Ford vehicles sold in Europe in 2015 were equipped with the 1.0-litre unit, including almost two in five Fiestas.

The 1.0-litre EcoBoost petrol is available in Ireland with different power outputs in the Fiesta, EcoSport, Focus and C-MAX.

EcoBoost technology also appears in high performance models from the Ford range. The Fiesta ST produces 182hp from a 1.6-litre EcoBoost engine. The Focus ST produces 247hp from a 2.0-litre EcoBoost. The Ford Mustang EcoBoost produces 312hp from a 2.3-litre turbo petrol engine.

Rival brands have also in recent years come up with their own range of small, turbocharged petrol engines, including Volkswagen, Kia, Peugeot/Citroen, Suzuki and Opel.
