The new 185 PS 2.0-liter diesel engine that debuts in the new Focus ST has been optimized to deliver ST performance and character alongside fuel efficiency and everyday practicality. The increased power output of the Focus ST 2.0-liter TDCi—a 23 per cent gain over the 150 PS 2.0-liter engine in the new Focus range—is achieved by electronic calibration, a revised air intake system and a new sports-tuned exhaust.

This new version of Ford’s diesel has less friction, reduced parasitic losses and an electronically controlled variable flow oil pump to further aid the reduction of emissions and improvement in fuel economy.

Peak power is developed at 3,500 rpm and there is 400 N·m (295 lb-ft) of torque available from 2,000-2,750 rpm, enabling the new Focus ST diesel to achieve a maximum speed of 217 km/h (135 mph). The torque output enables impressive in-gear acceleration and strong performance at low rpm. In 6t^h gear, acceleration from 80-120 km/h (50-75 mph) takes just 9.7 seconds in sixth gear, the combination of a shorter ratio and the increased power enabling the Focus ST to outpace the 150 PS Focus by 2.2 seconds.

The 250 PS (247 hp, 184 kW) 2.0-liter EcoBoost delivers 0-100 km/h (0-62 mph) in 6.5 seconds, fuel efficiency of 6.8 l/100 km (34.6 mpg US), and 158 g/km CO₂. Both models offer Auto-Start-Stop for the first time that improves the EcoBoost version’s fuel efficiency by 6% and help make it the most fuel-efficient gasoline Focus ST.

Ford’s 2.0-liter EcoBoost engine uses turbocharging, Twin-independent Variable Cam Timing technology, and high-pressure direct-injection to deliver uncompromising performance. Peak power is available at 5,500 rpm, 360 N·m (266 lb-ft) of torque is available from 2,000-4,500 rpm, and maximum speed is 248 km/h (154 mph).

Both engines use a six-speed manual transmission with a performance-oriented, short-throw shift. The gear ratios—exclusive to ST and matched individually to each engine—deliver rapid acceleration in lower gears and comfortable cruising at speed.

Driver assistance, convenience and connectivity technologies that will be introduced for the first time include the Ford SYNC 2 connectivity system. SYNC 2 offers access to audio, navigation, climate control and mobile phones using class-leading voice control and a high-definition, 8-inch color touchscreen that displays the ST logo on start-up.

Adaptive Front Lighting, available for the first time on the Focus ST, adjusts the intensity and angle of the Bi-Xenon HID headlamp beams according to vehicle speed, steering angle and distance to objects to provide optimal illumination. Cross Traffic Alert also is a new addition for Focus ST, and warns drivers reversing from parking spaces if other vehicles are about to cross their path.

Ford’s enhanced Active City Stop collision avoidance system—now operative at speeds of up to 50 km/h (31 mph)—readies the brakes if a potential impact is detected and—if the driver does not respond—will automatically apply the brakes. Lane Keeping Aid applies steering torque to guide the Focus ST back in to lane if drifting is detected.

Ford Team RS, the award-winning European arm of Ford’s Global Performance Vehicle group, made improving the entire driving experience the number one objective for the new Focus ST.

The sports suspension features all-new front springs and sportier new shock absorber tuning front and rear. In combination with the model-specific anti-roll bars and rear springs from the previous generation ST, these enhancements deliver an even sharper dynamic performance.

The calibration of the Electronic Power Assisted Steering and electronic vehicle control systems also has been revised to meet the specific sporting requirements of the new Focus ST. These changes deliver:

• A new Electronic Transitional Stability function in the advanced three-stage Electronic Stability Program. This senses vehicle stability and driver inputs, intervening as required to maintain optimal precision and control during rapid changes of direction at speed—in a lane-change situation, for example.

• Revised Electronic Torque Vectoring Control settings that further optimize wheel torque distribution, maximizing traction through corners and increasing agility Power delivery refinement under hard acceleration—particularly front wheel traction and gear shift quality—is also assisted by engine mounts engineered specifically to accommodate the performance of the new Focus ST. Additionally, Ford worked with Michelin to develop a new 19-inch tire that complements the driving dynamics, especially maximizing lateral grip.

Available to order in Europe from autumn 2014, the first new Focus ST models are scheduled to be in dealerships from early 2015. Pricing will be announced closer to the on-sale date.
