Getting 140 horsepower out of Ford's three-cylinder Ecoboost makes the Fiesta Zetec S the most powerful 1-liter road car ever built. Would you like it in red or black?
Overboost is the word that pops in my mind when I look at this car, but since it has a factory warranty, I guess it should be fine.
Ford says they recalibrated turbocharger boost control, valve-timing, the intercooler, and throttle management, so while the standard Fiesta gets 123 horsepower, the Europe-only Zetec S comes with 17 more, giving it a 0-62 acceleration time of 9 seconds and a top speed of 125 mph.
