Roll, Pitch Yaw Inertia's of medium sized sedan

[JakubMech]

Im starting up an initial dynamic model of a medium sized sedan, front engine layout, all wheel drive, around 1400kg (3000lb), would anyone have figures for roll, pitch, yaw inertia's for something like this?

Regards

Greg,

That would produce a radius of gyration in pitch of about 1.17 m. Typical for an AWD vehicle?

Best regards,

Another source for inertias is the NHTSA site ... measured and derived data.
