Performance and Efficiency

The All-New Fiesta ST is powered by a potent 1.5-litre EcoBoost petrol engine. Already impressive efficiency is increased by a particularly ingenious feature: a cylinder that deactivates automatically when it’s not required, saving fuel when you’re cruising. A series of additional technologies also help enhance the car’s performance whilst helping to save fuel.

Features shown on this page may only be available on selected models. Where available, these features may be optional extras at additional cost. For more info, download price list to view current ROI specifications.

Pure, yet refined power

Exceptional performance is powered by an all-new, three-cylinder 1.5-litre EcoBoost engine. The engine’s new turbocharger technology utilises an optimised turbine design which builds boost pressure faster. It also minimises lag. Designed to reduce friction with a two-stage oil pump and develop less vibration. In addition, the combination of port fuel injection and direct fuel injection technology helps deliver high power and responsiveness. The result: Fiesta ST delivers exceptional performance with 200 PS, a muscular 290 Nm of torque at 1,750 rpm and an anticipated 0-100 km/h (0-62 mph) time of 6.5 seconds.

Grip when you need it

A mechanical slip differential is included with the optional performance pack. The system is designed to transfer engine power to the rear wheel with the most grip. So as soon as one wheel starts to slip, power is automatically transferred to the other wheel to keep both wheels driving. The result: greatly improved traction on slippery or uneven surfaces and better acceleration and performance overall.

Revel in the sound

With Electronic Sound Enhancement and Active Valve Exhaust you’ll enjoy the Fiesta ST experience to the full. Why: because Active Valve Exhaust is a new technology designed to create a deeper, rumble and roar based on the amount of throttle you apply. And Electronic Sound Enhancement ensures you’ll hear the evocative engine when you’re behind the wheel.

Use less fuel with Auto Start-Stop

When you stop at traffic lights or your Fiesta ST is idling in a queue, this technology can automatically switch off the engine while still supplying power to essentials like the headlights, air-conditioning and the Ford SYNC 3 system. When you're ready to move just depress the clutch, or press the accelerator on an automatic, and the system restarts. Auto-Start-Stop is particularly effective in towns and cities, where it can cut fuel consumption by up to 10% (urban cycle).

Six gears at your disposal

A 6-speed manual transmission is designed to help make the most of the power available to you. Shifts are short and fast and deliver smooth, precise performance with each and every gear change.

Better aerodynamics for improved economy

When you’re driving slowly, the Active Grille Shutter system keeps the grille vent open to cool the engine. When you pick up speed it can automatically close, improving aerodynamics and helping to save fuel. Over time, this technology can make a big difference.

Engines that meet strict standards

It’s reassuring to know the 1.5-litre EcoBoost engine on Fiesta ST will meet Euro Stage 6 emission standards. For petrol engines, Stage 6 emission standards mean the engine can produce no more than: 1.0 g/km of carbon monoxide, 0.10 g/km of hydrocarbon, 0.06 g/km of nitrogen oxides and 0.005 g/km of atmospheric particulate matterTooltip.
