What does "wheelbase" refer to in vehicle specifications?

"Wheelbase" specifically refers to the distance between the front and rear axles of a vehicle. This measurement is important as it influences vehicle handling, stability, and turning radius. A longer wheelbase generally contributes to better stability and a smoother ride, while a shorter wheelbase can enhance maneuverability and responsiveness, especially in tight spaces.

The options that do not describe wheelbase include the total length of the vehicle, which encompasses all exterior dimensions, but does not specifically pinpoint the axle distance. The distance between the driver's seat and the steering wheel pertains to driver comfort and ergonomics, rather than a measurement that defines the structure of the vehicle. Finally, the height of the vehicle relates to its vertical dimension from the ground to the highest point, which is unrelated to the wheelbase measurement.
