2. The track width of the vehicle, with wider track widths resulting in smaller turning radii.
3. The suspension system of the vehicle, with more advanced suspension systems allowing for tighter turning radii.

Types of Vehicles and Their Turning Radii

Different types of vehicles have varying turning radii, with compact cars and city cars typically having smaller turning radii than SUVs and trucks. This is due to the smaller size and lighter weight of compact cars, which makes them more maneuverable in tight spaces. Additionally, some vehicles, such as luxury cars, may have more advanced steering systems that allow for tighter turning radii.
