My Ride: Arrived 3 June 2005: 2005 545i - Orient Blue, Black interior, Sport, Steptronic, Cold Weather, NAV, Sirius, Logic7, Comfort Seats, Sunshades. What a glorious ride!
There was some question a while back regarding whether the engine in the 550i is still full Valvetronic. According to the BMWUSA website, it is:
Valvetronic
Valvetronic replaces the function of the throttle butterfly with continuously variable valve lift control, to enable the engine to breathe more easily. An electric motor controlled by the accelerator pedal turns an eccentric shaft, which transmits the rotation of the cams to the valves via a connecting lever. Controlling the position of the eccentric shaft controls the ideal valve lift. The result is remarkably smooth and optimized power and efficiency at all times.?
