Come and say hello to the next generation of the performance version of the Ford Fiesta, as powered by a three-cylinder engine. Wait, a three-cylinder engine? Yes, that’s no typo. The new generation of the Ford Fiesta ST is really powered not by a four-cylinder or a six-cylinder, but by a three-cylinder engine.
This new three-cylinder powerplant features a displacement of around 1.5 liters and is armed with an array of superior engine technologies like turbocharging, Twin-independent Variable Cam Timing and high-pressure fuel injection – all of which allow this mill to provide better performance as well as superb fuel efficiency.
The new mill is able to deliver 197 hp (147 kW or 200 PS) of max output and 214 lb.-ft. (290 Nm) of peak torque, allowing the new generation of the Fiesta ST to sprint from zero to 62 mph (100 km/h) in just 6.7 seconds. It is as powerful -- but has more torque -- as the current 1.6-liter turbocharged four-cylinder engine fitted on the base North American version of the current Ford Fiesta ST.
This engine delivers up to 197 hp (147 kW) of output and up to 202 lb.-ft. (274 Nm) of torque. Moreover, the new 1.5-liter three-cylinder is also more powerful – both in output and torque – than the Europe version of the 1.6-liter turbocharged four-cylinder engine that could provide around 180 hp (134 kW) of output and 177 lb.-ft. (240 Nm) of torque.
Part of Ford’s vaunted family of EcoBoost engines, this new three-cylinder mill is designed to have naturally high torque even at low rpm. Its new turbocharger system employs an optimized turbine that could build boost pressure faster while minimizing lag.
Interestingly, this new 1.5 three-cylinder EcoBoost engine features a cylinder deactivation technology. When there is no need for the engine to work on full load, this technology would deactivate one of the three cylinders – by automatically stopping its valve operation as well as fuel delivery. Drivers won’t even feel that a cylinder is deactivated or reactivated, since the while process only takes 14 milliseconds. This way, the engine doesn’t have to consume more gas than is actually needed.
Interestingly, the next-gen Ford Fiesta ST features new selectable Drive Modes: Normal, Sport and Track. In Normal mode, the Fiesta ST’s engine mapping, traction control and electronic stability control (ESC), as well as exhaust sound and electronic power assisted steering (EPAS) are programmed for natural responsiveness. Sport mode sharpens the engine mapping as well as the throttle pedal response and adjusts the EPAS settings for more feedback. In Track mode, traction control is disabled while vehicle dynamics elements are configured to achieve fastest possible lap times.
Ford will unveil the new generation of the Fiesta ST at the upcoming 2017 Geneva Motor Show in March.
