2013 Ford Focus ST: The Overboosted Ecoboost
December 02, 2012
Glad to see that Ford put a little effort (very little) into making this engine look special, it deserves it. Not only does this turbocharged 2.0-liter put out just over 250 horsepower, it does it in a way that makes it usable in almost any gear.
No need to wind it by the intake manifold to get it going. Peak torque arrives at around 3,000rpm and uh stays peaked. This is due to an overboost feature that cranks up the turbo boost for up to 15 seconds to keep the torque curve flat. It sounds gimmicky, but it works and works well.
Lots of turbocharged four cylinder engines have been claiming to deliver V6 power with four-cylinder mileage. So far, I'd say this engine delivers on that promise better than anything else I've driven.
