The CT is supposed to have 14" wheel travel (6" of adjustable air bag suspension). It has full rock sliders around the entire truck (sides + front/rear) and the entire body is made to be scratched (well.. avoid showing scratches).
I'm 100% sure Tesla has been doing different types of off-road testing.
This is just a fun video... by the same guy who went viral once by saying he's selling a car because the tires were bald.
