The M440i's main differentiating factor is its 382-hp six-cylinder engine and the accompanying performance upgrades that include M Sport brakes, suspension, differential, and variable steering. On the outside, it still has 18-inch alloys, but these are two-tone M items, while an aerodynamic body kit, M rear spoiler, and Shadowline exterior trim are also added. Whereas the base cars have wood interior trim, the M440i has Aluminum Tetragon trim, as well as an M steering wheel.
