The Ford Fusion is a mid-sized sedan that fits between the compact Focus sedan and the larger Taurus in Ford's lineup. However, the Fusion may be the most important car that Ford makes as it competes in the hotly contested mid-sized segment. The Fusion offers distinctive styling, a wide choice of powertrain and a good value. With prices starting below $20,000, the Fusion is a good alternative to other mid-sized models and compact models. Higher trim levels add features and powertrains that compare favorably with the segment leading Toyota Camry. The Fusion's four cylinder and hybrid models offer exceptional fuel economy. The availability of all-wheel-drive distinguishes the Fusion from most other vehicles in the segment.

The 2010 Fusion wears updated styling on the inside and out. Exterior changes include a new front end with a more pronounced grille and a domed hood. The revised rear styling features new taillights and a new trunk lid. Revisions to the interior include a new instrument panel, new center stack, and new door trim. New 2.5L four-cylinder and 3.0L V6 engines paired with six-speed transmissions improve power, acceleration and fuel-efficiency over prior models. A long-awaited full hybrid model pairs the 2.5L four-cylinder engine with an electric motor propulsion system for exceptional fuel economy. A new Sport model offers the 263-bhp 3.5L V6 found in the MKZ for the first time in the Fusion.
