Think of this crazy thing: I took my Prius off-road to a place where you are supposed to go only with an SUV. The exact location is shown here.
The place is at the southest point of Peloponissos, Greece known as the fossil forest. The route was 12 Kms of really bad road full of stones and great up/down hills.
Prius performed as a usual car on the road. However, I did have a problem with a great uphill because I stopped in the middle of it. Doing so, I couldn’t continue from there so I had to go reverse and try it again with some speed.
