BMWNA quotes that there 530i with automatic weights in at 3494 pounds, yet when tested by magazines with out the driver in it such as road and track they quote the weight of the car as 3660 pounds. I find that to be a huge difference. car and driver even tested a 530i when it first came out with a manual tranny and there test cars curb weight was 3756 pounds. does the premium package, sport package and other extras make the cars weigh that much more? I think BMW should give out the information on how much each options additional weight would be on there cars.
