I took my new to me 2009 RAV4 V6 4WD up to the SoCal mountains over the weekend. I was impressed with how well it ran on mud, ice and snow. It powered straight through and was very well controlled. Areas that were completely impassable for 2WD cars (w/o chains) were easily passed without any slipping by my RAV4. It ran much better than my 2001 X5, which tended to slide around a bunch more in similar conditions. I'm really impressed with this car.
