I'm talking about old WWII Willy's Jeep. They were heavy 4-cylinder 60 HP but they could still drive through deep mud with 6 or more people on it. Plus, it did this in 4wd. How come modern cars with more HP can't do it? I'm watching a WWII documentary and it seems like the little 60 hp was bullet proof or something and didn't have a limit on anything. Modern cars now with the same HP seems so fragile.
