The new M550d xDrive sedan and wagon (Touring) has a standard rear biased all-wheel drive system, 8-speed automatic, sport suspension, and active steering. There’s also an M spoiler, exhaust and brake package installed.

It 19-inch wheels with 245/40 tires at the front and 275/35 R19 tires at the rear. Also standard on the M550d are grey mirror housings, grille frame, bumper highlights, and air breathers.
