The Ford Fusion is a mid-sized sedan that fits between the Focus compact sedan and the Five Hundred large sedan. The Fusion is distinguished by distinctive exterior styling which is a little less generic than new mid-sized offerings. Mechanically, the Fusion is based on a version of the competant Mazda6 platform. Offered in three trim levels, Fusion is offered with both four-cylinder and V6 engines. Four-cylinder models can be equipped with either a 5-speed manual or automatic transmission. The V6 model features a six-speed automatic as standard equipment. An all-wheel-drive model will join the lineup in the 2007 model year and a Hybrid powertrain has been promised. The interior features a number of appearances based on color and trim level, but can be configured with an all-black leather interior similar to the 2003 Ford 427 concept car from which the Fusion was inspired.

The Fusion gains an optional AWD drive system.
