Thanks Joe for the data point. I'm curious now what my non-sunroof 6MT E90 M3 weighs under similar conditions. I'm glad you mentioned all the stuff you removed from the car as I might not have thought to do that.

Forum member Richbot weighed his non-roof 6MT E90 with 3/8ths of a tank of fuel and got 3522 lbs. If he dropped to your fuel load, maybe that's ~15lbs, so that would get it down to 3507 lbs. He has the M performance exhaust though which is 20lbs lighter than stock, so that would put him back at 3527 lbs.

So things removed would include: floor mats, everything in glovebox, all nooks, trunk, mobility pack...what else?

One thing to realize is that BMW quoted weights of course include stuff like mats, mobility pack, etc.

Even still if Richbot's example is at ~3527 and you're at 3450, that's a 77lb weight difference between the E90/F80. We do know that 31lbs of that is due to the Li-ion battery in the F80. That gives 46lbs of weight reduction in the overall car, which given the significant increase in size of the F30/80 chassis and all is a great achievement in my opinion.
