You can drive anything on the beach, you may not get far. You need the 4 wheel drive system to be full time. The AWD will only kick in when your slipping. Therefore you risk the chance of getting stuck, and before you know it your all f&^%% up. I drove a GMC Envoy all over Long Island's beaches last fall. I also got really stuck a few times. Its no fun. 4 low is the only way to go. You also have to be aired out. I own a Sieana and I think it is a great vechicle. I would never trust it on the beach.
