BMW lists the static torsional rigidity of the E46 in its sales training literature. it is as follows:
sedan 18000Nm per degree of torsion
sedan w/fold downs 13,000Nm
sport wagon w/fold downs 14,000Nm
coupe w/fold downs 12,500
like i said the difference is pronounced -- sharper turn in, less disturbed by mid-corner bumps, smoother ride (less 'jiggle').
that said, the E46 convertible apparently about the same torsional rigidity as the E36 coupe. (!)
