Yes; torsional rigidity.Originally Posted by wwgkd
Measured in Nm/deg; to deflect the chassis by 1 degree would require however many Nm of torque to be applied.
Considering that the rigidity of most modern cars is measured in thousands of Nm/deg, I doubt 300Nm from the engine is going to be doing much flexing...
Print out/ save the picture of the evo and show it to whomever is tutoring you on this project, and tell them you think it is "'chassis flex' because it is a cheap 'econo-car'".
Tell us what the reply is, and whether they were able to keep a straight face.
Also, as you're testing this, get an Evo, or even a Lancer, and find out how much force is required to get an equivalent deflection of 5".
True - a sheet of material will be stiffer with fewer holes cut into it, however, if you cut more holes out and then add reinforcement...
BMW E46 Sedan (w/folding seats) 13,000 Nm/deg
BMW E46 Coupe (w/folding seats) 12,500 Nm/deg
In instances where a car is available in 2 and 4 door versions, the 4 door is odds-on to be stiffer because;
- Smaller doors - 2 door versions usually have larger door openings to enable better access to the rear seats.
- B-pillars - supporting 4 doors and acting as side impact protection, they tend to be quite strong.
I think you will find that there is probably a more "down to earth" explanation to why the Evo in question is impersonating a tripod, and it is probably due to the raised red and white lumpy things it has just driven over.

See below - is that massive chassis flex, or cars bouncing off each other?
I would never dream of making sarcastic comments.
