What Does Minimum Turning Radius Mean?

Minimum turning radius refers to the radius of the circular trajectory rolled by the center plane of the outer steering wheel on the supporting surface when the steering wheel is turned to its limit position and the vehicle is turning at the lowest stable speed. To a large extent, it characterizes the vehicle's ability to pass through narrow curved areas or bypass insurmountable obstacles. The smaller the turning radius, the better the vehicle's maneuverability. There is a calculation formula for the minimum turning radius: It is the wheelbase divided by the sine value (sin value) of the maximum steering angle of the front outer steering wheel. The minimum turning radius is directly proportional to the wheelbase and inversely proportional to the maximum steering angle of the front outer steering wheel. There are two ways to reduce the minimum turning radius: One is to shorten the wheelbase, and the second is to increase the maximum steering angle of the front outer steering wheel.
The minimum turning radius simply refers to the smallest circular radius a car can make when the steering wheel is turned to its fullest. As a seasoned driver with over a decade of experience, I find this parameter extremely practical, especially in urban areas. My compact car has a small turning radius, allowing me to make tight U-turns effortlessly in narrow alleys or crowded mall parking lots, saving both time and effort. In contrast, my friend's SUV has a larger turning radius and struggles even in small parking spaces. Essentially, a smaller value indicates better maneuverability, which is related to the car's wheelbase and steering angle design. When choosing a new car, I always check the manual's specifications and test the turning radius during a test drive to avoid bulky vehicles. Regular maintenance of tire pressure and the steering system helps maintain this performance and reduces the risk of scratches in emergencies.
