Btw, I've seen a lot of people over the past couple days on other forums be turned completely off when they saw the 1560 kg. I'm tired of informing. The Devil is in the details.

I am still uncertain if the calculations are right. If we compare apples to apples the UK has 335i listed at 1600kg and the 135i at 1560kg that means the 135i is only 88lbs lighter than the 335i. Comparatively this is shocking consider the 135i is smaller.
Base on your calculation the weight of the 135i will be at 3274 but applying the same method to 335i it will put 335i some where in the same ball park as well. In fact 335i will probably have a advantage because it has a bigger gas tank. Therefore, a slightly larger portion of its 1600kg unladen weight comes from gas, but not its true mass. This will narrow the mass gap between the 1 and 3s.
What's even more shocking and might annoy 335i driver is the UK 530i weights only 5kg, at 1605kg, more than the 335i.
On BMW NA website the weight difference between 535i and 335i is around 80lbs just like the weight difference between 335i and 135i. If your calculation is correct then the true weight of 135i is 3274lb, 335i 3354lbs and the 535i is 3434lbs.
