If the wheelbase is too short or too long, it will affect the performance of the entire vehicle.
The shorter the wheelbase of a car, the shorter the length of the car, the lower the mass, the smaller the bend radius and the longitudinal passage radius, the better the maneuverability of the car. However, if the wheelbase is too short, the length of the carriage will be insufficient, and the rear overhang (the distance between the vehicle's last wheel axis and the rear end of the car) will be too long, which will cause large longitudinal swing during driving and mass during braking, acceleration or uphill. The larger the transfer, the worse its handling and stability.
If the wheelbase is too long, the length of the vehicle body will increase, and the rear blind zone will also become large. If you do not increase the reverse radar, reverse is a severe test for novices.
