Don't know if there is an official limit. But like the other guy said, usually if you need 4WD, you probably shouldn't be going fast.

However, on some days when I need to commute and the road condition changes a lot. I have had it in 4WD going as fast as maybe 65mph for a few miles on wet pavement. When I hit snow, of course the speed drops a lot.

I also think I have driven at 55 for longer periods, maybe 20-30 miles or more at a time.
