The M550i gets a decent bump up in standard specification over the 540i to complement the burly V8. Outside, this model is distinguished by 19-inch M double-spoke wheels, an aerodynamic kit, black chrome exhaust tips, Shadowline exterior trim, and an M rear spoiler. Luxury adornments are taken up a few notches with a SensaTec-trimmed dashboard and 20-way power multi-contour front seats; these seats provide power shoulder and thigh adjustments along with a comfort headrest and a memory system for the front seat passenger. While every 5 Series gets the convenience of auto-on headlights and rain-sensing windshield wipers, the M550i also boasts a hands-free trunk-lid open/close function. The excellent Harman Kardon sound system has 600 watts of power from seven tweeters, seven midrange speakers, and two bass speakers.
