Η Ford ανακοίνωσε ότι το νέο Focus ST διαθέτει λειτουργία overboost η οποία αυξάνει για 12 δευτερόλεπτα την απόδοση του 2.0-λιτρου EcoBoost turbo κινητήρα. Ο κινητήρας αποδίδει 250 άλογα με 360 Nm ροπής, αλλά με τη λειτουργία Ecoboost από τις 3.000 σ.α.λ έως τις 4.500 σ.α.λ, αποδίδει 255 άλογα με 366 Nm ροπής, μια αύξηση της τάξεως του 7.7%.

Ford Focus ST Features Factory ‘Overboost’ Turbo Engine
- Ford Focus ST increases acceleration through factory “overboost” turbo feature that extends torque curve from 3,000 rpm to 4,500 rpm for up to 15 seconds
- Turbo tuned to decrease response time and increase power throughout rev range
- Ford confirms the Focus ST’s SAE-certified engine output of 252 horsepower and 270 lb.-ft. torque from efficient 2.0-liter EcoBoost® engine with low-inertia turbocharger
Pilots might call it the Focus with afterburners. Everyone else will call it really fast.
The new Ford Focus ST features a four-cylinder, direct-injected turbocharged engine with an “overboost” feature that extends peak torque for up to 15 seconds at a time.
The gains extend the peak torque from 3,000 rpm to 4,500 rpm, whereas other EcoBoost® engines would hit peak torque and begin to drop off at these higher engine speeds. This is the first overboosted Ford EcoBoost engine sold in North America.
Ford engineers made sure the overclocked EcoBoost 2.0-liter would have a very robust cooling system. “The turbo itself is specified for sustained, high-output performance, but they’ve programmed the car’s computer to dial in more boost past 3,000 rpm to give it that extra something,” says engineer Lisa Schoder, who is Marketing manager for Focus ST.
“We limit peak turbo boost to maintain a wide margin of safety and durability over the life of the car,” Schoder adds. “But overboost is cool in that it tweaks more acceleration through the turbo for brief periods for performance-hungry drivers.”
Among the more visible options will be the Tangerine Scream metallic color that will be offered exclusively on Focus ST, as well as race-inspired Recaro® seats with matching color accents.
Ford is offering drivers who preorder a Focus ST the GoPro® HD Hero2 Motorsports Edition camera pack upon delivery. Already a staple in the motorsports and action sports communities, GoPro is the ideal camera to capture a spirited drive or Focus ST track day. The first 1,000 presale orders placed between May 1 and Aug. 20 are eligible for the GoPro HD Hero2 camera. The cameras will be sent after vehicle delivery.
