So most magazines have been saying that the new 2011 535i is going to weigh about 4100 lbs and that the 550i around 4400 lbs. After doing careful research on the BMW F10 catalog it shows the 528i coming in at 1730 kg, the 535i at 1775 kg and the 550i at 1905 kg. To convert over to lbs you multiply the kg number by 2.2 this means that the 528i should be around 3806 lbs, the 535i at 3905 lbs and the 550i at 4191 pounds. Specs are with the 8-speed auto gear box, 150 lbs driver, 15.4 lbs of luggage and 90% Tank full of gas. In reality these cars shouldn't be much heavier at all from the current
E60 models. Subtract 108 lbs since each Gallon of gas weighs 6.5 lbs, the driver 150 lbs and the luggage 15.4 lbs and the cars should weigh as follows

528i without driver, luggage or gas: 3533 lbs
535i without driver, luggage or gas: 3632 lbs
550i: without driver, luggage or gas: 3918 lbs

528i with 150 lbs driver, 15.4 lbs luggage and 90% full tank of gas: 3806 lbs
535i with 150 lbs driver, 15.4 lbs luggage and 90% full tank of gas: 3905 lbs
550i: with 150 lbs driver, 15.4 lbs luggage and 90% full tank of gas: 4191 lbs

Let's see what the official numbers are from BMWUSA when they release USA spec cars. Let's hope I am correct on this.

Sorry I fixed/edited the numbers. I made sure they are correct this time.
