The one thing that seriously limits the "off road" ability of a 4Motion Cali is the rear departure angle - it's comically small! A long overhand with a shallow angle means it's very easy to scrape the back - add mud flaps (like we have) and you have a scraping noise on almost anything with angles on it!
Traction is impressive though - better than I expected for what is (usually) a "part time" 4WD system (Haldex).
