2013 Ford Focus ST: Four Sounds Like Five
November 07, 2012
The first time I drove our longterm 2013 Ford Focus ST, I coulda sworn it was a five-cylinder. It really is uncanny -- this 2.0-liter turbocharged four cylinder makes induction sounds that definitely ape those of an inline-5.
When you're at light throttle, the ST' engine is unobtrusive. Just a bit of smooth pattering and little more. Really civilized. Only when you give it some right foot does an electronically actuated valve open, allowing induction noise to filter into the cabin via an intake honkus. It sounds terrific, too.
And it turns out its five-cylinder sound effect was intentional -- Ford engineers wanted to replicate the sound of the five-cylinder engine of the previous-gen Focus ST in the new car. Mission accomplished -- the 5-cyl warble is unmistakable.
