1 Puzzle Piece Solved: Why MANY New Cars I Tested < the 8; 30,000 Nm/degree
This is old news to many of you, but for whatever reason, I only recently bothered to learn that the RX-8 has torsional rigidity that is extremely high compared to many vehicles in the same class (or even vehicles deemed a notch or two above).

This is yet one more reason that probably helps to explain why my multi-year quest , test driving well over 15 new cars, in an effort to find a replacement for my 8, came up empty.
Mazda RX8 - 30,000 Nm/degree
These numbers for torsional rigidity are hard to find, and the list that I did find is not perfectly up to date, but it pretty much establishes that only a few cars short of 100k (or even more, for that matter) can match the RX-8 in this area.
I had both BMW E46 that I thought was solid, but a jaunt over railroad tracks at 55 mph+ has always suggested to me that the RX-8 has an especially rigid structure, and now I know why.
What's remarkable is how Mazda engineers accomplished this WITHOUT fixed B pillars.

we raced an E46 for a season and once we put it under the microscope, its really a lousy POS. the strut towers bend, on STOCK cars, the rear suspension is literally bolted to the trunk floor, IE a single layer of sheetmetal, with 4 bolts. the E36's have 2 bolts and the suspension falls out, so they just added 2 more bolts, so it still falls out it just takes twice as long. the beefiest part of the car is front of the hood, which is inexplicably 8 layers of sheetmetal, that's 7 layers more than the structure of the car!
chicks dig it though.

I test drove an E46 M3 convertible before I was thinking of trading my 8 in. test drove it. man it felt like a soggy take-out dinner box. 8 is so much better.

Link I forgot to post where someone claims the RX-8 has higher torsional rigidity than any BMW ever produced but one?
