Comparison between the different vehicles in Fortnite—Battle Royale?

Quadcrasher is a vehicle in Battle Royale. It seats two players and builds up boost just by anyone sitting in the driver's seat. Using the boost will speed up the Quadcrasher and make it able to smash through almost anything. Driving into players while boosting will send them flying upwards, potentially causing major fall damage. The boost can also be used to get some big airtime on ramps or to climb up mountains. Quadcrasher can be found throughout specific locations of the map and spawns all the time. HP 400

ATK (stands for All Terrain Kart) is a vehicle in Battle Royale. It can fit 4 players and gets speed boosts after powersliding. It's roof acts like tires.HP 400

Shopping Carts allow a driver, which can move and push the Shopping Cart, and a passenger, which can shoot, build, harvest materials and use emotes. They cannot crouch, however. Shopping Carts are seemingly hidden around the map, usually in corners, inside buildings, on top of mountains, etc. Just like the majority of objects, their spawn points are variable and therefore, they cannot be always found on the same spot.
