And when comparing numbers, they're pretty much bang on.
128i according to you is 3252lbs. *0.45 = 1463kg (actually 1480 bang on using the more exact measurement from onlineconversion.com)
List weight of a coupe (with butt) 125i here is 1480kg.
The 28i and the 25i is the same 3 liter block.
Converted, the 535i has a weight of 1647kg. The 540i has a list weight of 1625. That's with a litre more, less torque, same hp (and I think a gearbox not as strong compared to the executioner-style 35i engine).
All that, and taking into account the difference between US (curb weight) and EU1 (curb weight + driver), the numbers are correct.
You listed from BMW USA a curb weight of 3373lbs for the 135i. That's 1517 kg's! Minus the 75kg driver we take into account in Europe, that's 1592 fully loaded. The slight difference is because the US version is probably a bit higher loaded on trim and extra's.
Even if the US number is *with* driver. Then the 135i is still well over 1500 kg's @ 1517. So even if I'm *wrong*, I'm right, because:
135i = pig and a lot heavier than some 5-series.
And to prevent further confusion:
1 pound = 0.453 592 37 kilogram
