Ford Fiesta Sedan (2010) | USA Top CarsUSA Top Cars - Ford Fiesta Sedan (2010) features a 1.6-liter DOHC 4-cylinder engine that is rated at 120 horsepower and 112 pound-feet of torque. This four-banger features Twin Independent Variable Camshaft Timing (Ti-VCT), which allows smaller displacement for increased fuel economy without compromising performance. Ford also makes use of an aggressive deceleration fuel shutoff, combined with an engine accessory drive system that was designed to improve efficiency by reducing the energy it takes to power the air conditioner and alternator. When coupled with electric power assist steering, the small gains translate to measurable gains in fuel economy. In order to meet federal crash standards and compensate for the switch from European summer tires to all-season tires, Ford reports that the front anti-roll bar was increased from 19 mm to 22 mm, and the rear twistbeam saw a 28 percent increase in rigidity, compared to the European Fiesta. Ford also added a push-button feature - Grade Assist - which essentially helps to maintain low gearing for more responsive throttle under acceleration, as well as reduced braking during grade descent. Customers can choose from 15 or 16-inch wheels on most models, and an available 17-inch Ford Racing wheel as well.
