Ford presents next generation of Fiesta ST with new 1.5 three-cylinder engine

Article by Christian A., on February 27, 2017

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.

Press Release

NEXT-GEN FORD FIESTA ST DEBUTS 200PS, THREE CYLINDER, 1.5-LITRE ECOBOOST ENGINE AND DRIVE MODES

Ford Performance today announced the next generation Ford Fiesta ST, powered by an all-new three-cylinder, 1.5-litre EcoBoost engine.

Shown for the first time ahead of its global public debut at the Geneva Motor Show next month, the next‑generation Fiesta ST will deliver 200PS, 290Nm of torque and anticipated 0‑62mph acceleration in 6.7sec.

The third generation of Fiesta ST will be the first ever Ford Performance model powered by a three-cylinder engine, and the first Fiesta ST to feature selectable Drive Modes – enabling engine, steering and stability controls to be configured to Normal, Sport and Track settings for an optimised fun-to-drive experience in conditions from motorways to track days.

Drive Modes will also adjust Fiesta ST’s Electronic Sound Enhancement (ESE) technology and active exhaust noise control valve to deliver an even more satisfying driving experience. The technologies amplify the naturally sporty sound of the new 1.5-litre EcoBoost engine that also features Ford’s industry-first cylinder deactivation system for a three-cylinder engine, for further reduced CO2 emissions of an anticipated 114g/km.*

Available from launch in early 2018 in both three-door and five-door bodystyles, the next generation Fiesta ST will be offered with a greater variety of interior trim and personalisation options than ever before, with bold and distinctive exterior styling that includes a unique race-car-inspired mesh grille and exclusive 18in alloy wheels.

“Our next generation Fiesta ST is true to the philosophy of delivering cutting-edge technology to enhance every facet of the responsive Ford Performance chassis and powertrain,” said Joe Bakaj, vice president, Product Development, Ford of Europe. “With selectable Drive Modes and an all-new EcoBoost engine delivering an unprecedented combination of performance and fuel-efficiency, the new model will deliver the most versatile, fun, engaging and rewarding Fiesta ST driving experience yet.”

All-new 1-5-litre EcoBoost engine

Part of Ford’s EcoBoost range of petrol engines that also includes the multi-award-winning 1.0‑litre EcoBoost, the all-new 1.5-litre EcoBoost engine uses technology including turbocharging, high-pressure fuel injection and Twin-independent Variable Cam Timing to deliver optimised performance and fuel efficiency.

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.

Ford’s new cylinder deactivation technology – first announced for the 1.0-litre EcoBoost engine and a world first for a three-cylinder engine – will further improve fuel efficiency for Fiesta ST customers without affecting performance by automatically stopping 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 thatimproves 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. Gas particulate filter technology that reduces soot emissions will also feature.

New Drive Modes

Selectable Drive Modes add even more versatility for the next generation Fiesta ST, enabling drivers to optimise the driving experience to suit scenarios from school run to the race track:

In Normal mode, engine mapping, traction control, electronic stability control (ESC), ESE, exhaust sound and electronic power assisted steering (EPAS) are configured to deliver natural responsiveness and a connected feel
In Sport mode, engine mapping and throttle pedal response are sharpened, and EPAS settings adjusted to deliver more feedback and finer control for fast road driving. The active noise control valve opens and ESE is adjusted to intensify the sporty exhaust note and engine noise within the cabin
In Track mode, all vehicle dynamics features are tuned for the fastest possible lap times, traction control is disabled and ESC interventions are set to wide-slip mode for hard circuit driving
The agile and responsive Ford Performance-tuned chassis will be supported by enhanced Torque Vectoring Control technology that improves road holding and reduces understeer by applying brake force to the inside front wheel when cornering. Three-mode ESC will enable drivers to choose between full system intervention; wide-slip mode with limited intervention; and full system de-activation.

Greater personalisation

The next generation Fiesta ST will offer more personalisation options than ever before. Customers will be able to choose from a range of trim elements for the gear lever, steering wheel, door pulls and decorative dashboard spear, and select from distinctive styling packs.

The ergonomic Fiesta ST interior will feature supportive Recaro seats and a flat-bottomed steering wheel. Exterior colour options will include new Liquid Blue and the Fiesta ST will feature exclusive 18in alloy wheels.

“Our ST models are designed to make a Ford Performance driving experience accessible to customers regardless of lifestyle,” said Matthias Tonn, Fiesta ST chief programme engineer. “With three- and five-door bodystyles and distinctive styling options that complement the model’s performance characteristics available from day-one, the next generation Fiesta ST will deliver a broader appeal for an even wider range of car-buyers.”

Ford’s SYNC 3 communications and entertainment system will enable Fiesta ST drivers to control audio, navigation and connected smartphones using simple, conversational voice commands. Compatible with Apple CarPlay and Android Auto™, SYNC 3 is supported by floating, tablet-inspired touchscreens up to eight inches in size that can be operated using pinch and swipe gestures.

The next generation Fiesta ST also will be offered with a high quality B&O PLAY Sound System for a high-end audio experience – among features Ford first announced last year for the next generation Fiesta.
