Not sure exactly but we have a town and country Chrysler mimi van and it fit with about 2 to 3 inches on both sides to clear it and yes had to fold in side mirrors 😉 but super fun you must experience it 😊
My Ford Edge did ok but I did fold in the mirrors
A hatchback can pass without any problem. I had a Mazda CX-5 and it went well. $5 entrance fee .
