BMW's mid-size cars grow for 2006 with three new all-wheel-drive (AWD) models. There are two sedans labeled 525xi and 530xi and a five-door sport wagon as the 530xi. Rear-wheel-drive (RWD) sedans include the 525i, 530i and top-trim 550i.

Six-pack power increases with in-line-six engines gaining Valvetronic variable valve lift. For 525i and 530xi, the plant delivers 215 hp, but for 530i and 530xi output climbs to 255 hp. Deluxe 550i sedan with the new V8 off the 7-Series runs to 360 hp. All 5-Series cars for 2006 incorporate the engine Start/Stop button also found on 7-Series sedans.

All also provide the spectrum of BMW mechanical systems for performance and safety, including Dynamic Stability Control (DSC) that can correct potentially dangerous car movements when wheels slip laterally. This year, BMW upgrades the DSC equipment by adding Brake Fading Compensation, Brake Standby, Brake Drying, plus Start-off Assistant.
