The current Ford Fusion remains one of the top picks in the midsize sedan segment. There are four trim levels -- S, SE, Sport and SEL -- while engine offerings consist of the base 2.5-liter four (175 horsepower), optional 3.0-liter V6 (240 hp) and, standard on the Sport, 3.5-liter V6 (263 hp). A six-speed manual transmission can be had on the 2.5, while optional for that engine and standard on the others is a six-speed automatic. Front-wheel drive is standard across the board with the exception of the SEL V6, which has all-wheel drive. The latter is optional on the Sport., , Standard feature highlights for the S include 16-inch alloy wheels, the MyKey system (limits top speed and audio volume), full power accessories, air-conditioning, and a stereo with a CD player and an auxiliary audio jack. The SE adds 17-inch alloys, foglamps, automatic headlights, an eight-way power driver seat and an upgraded audio system with satellite radio., , The Sport includes a sport-tuned suspension and steering setup, 18-inch wheels, exclusive styling cues, power front seats, leather upholstery and the Sync multimedia voice control interface. The Fusion SEL also features leather seating as well as heated seats, puddle lights, a numerical keyless entry pad and dual-zone automatic climate control. Options (depending on trim) include remote starting, a sunroof, a rearview camera, reverse park assist, a blind spot detection system and a navigation system., , In reviews, we've remained impressed with the Fusion's combination of responsive performance and well-balanced handling and ride dynamics. Inside there's plenty of room, quality materials and handy features. The Sync system is a great feature, allowing easy hands-free operation of cell phones and portable MP3 players. While not the largest car in its class, the Fusion's generous interior dimensions prove that a family sedan need not be as large as the Accord or Mazda 6.
