Which measurement helps in evaluating vehicle designs for tighter turning conditions?

The measurement that specifically aids in evaluating vehicle designs for tighter turning conditions is the front overhang (FOH). This measurement refers to the distance from the front axle to the front edge of the vehicle's body or bumper. In tight turning conditions, a shorter front overhang allows the vehicle to pivot more easily without the front end hitting obstacles, which can improve maneuverability.

While wheelbase, rear overhang, and overall width contribute to the vehicle's handling and turning radius, they do not directly indicate how well a vehicle can handle sharp turns in comparison to front overhang. The wheelbase affects stability and turning radius but does not specify the vehicle's ability to turn in tightly enough—same with rear overhang and overall width. Therefore, focusing on front overhang is most relevant when evaluating designs for tighter turning conditions.
