In a world where horsepower figures and economy sell cars, you’d be forgiven for questioning Ford’s wisdom when they said the 2.0L EcoBoost in the Focus ST would only have 252 horsepower. That’s about the same as the new Buick Verano Turbo, which isn’t exactly the most inspiring car in the world.
However, they did tune the engine a bit and the map they came up with features an overboost function which can extends peak torque for up to 15 seconds at a time. You don’t get more power per say, but the torque curve is much higher, which is excellent for quick overtaking maneuvers.
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.”
We’ll remind you that the Ford Focus ST is supposed to offer a 0 to 62 mph (100 km/h) time of just 6.5 seconds and a top speed of 248 km/h (154 mph).
