The new Ford Fiesta ST is here, ahead of the its full debut at the Geneva Motor Show in March. The smallest hot hatch in all the land gains more power, more refinement, and drops a cylinder in the new iteration. That’s right, the Ford Fiesta ST is powered by an all-new 197 horsepower turbocharged 1.5-liter 3-cylinder EcoBoost engine, Ford Performance’s first 3-cylinder model.Lest you think an angry triple won’t provide enough oomph, this one makes just as power as the old 1.6-liter four-cylinder. For Europe the new engine is 17 hp stronger; the 197-hp rating in the US was based on the engine’s temporary overboost feature, while the 180 hp European number is more of a permanent figure.
Ford claims a 0-62 mph (0-100 km/h) sprint happens in 6.7 seconds, the same as the outgoing -60 mph claim so expect a tenth or two improvement with the new car. While the torque rating is roughly the same, peak torque arrives at a lower RPM than in the previous Ecoboost engine. The ST’s three-banger also gets both port and direct fuel injection in order to order to lower CO2 emissions and reduce carbon buildup on valves. It should also see an increase in fuel economy.
The new 1.5-liter EcoBoost uses twin-independent variable cam timing, improving power and efficiency. Cylinder deactivation allows the car to run on two-cylinders under certain situations. The all-aluminum engine gets an integrated exhaust manifold and an all new turbocharger.
