What is the wheelbase of the BMW 1 Series?
1 Answers
The wheelbase of the BMW 1 Series is 2670mm, which is shorter than that of the Mercedes-Benz A-Class Sedan (2789mm). The importance of wheelbase: The wheelbase determines the position of the vehicle's center of gravity. Therefore, once the wheelbase is changed, the overall layout design must be redone, especially the dimensions of the drivetrain and body sections. The parameters of the springs and shock absorbers in the suspension system must be readjusted, as well as the dimensions of the steering trapezoidal linkage in the steering system. Too short or too long wheelbase: A shorter wheelbase means a shorter vehicle length, less mass, and smaller minimum turning radius and longitudinal passing radius, resulting in better maneuverability. However, if the wheelbase is too short, the cabin length will be insufficient, and the rear overhang (the distance between the rear wheel axis and the rear end of the vehicle) will be too long, leading to excessive longitudinal oscillation during driving and significant mass transfer during braking, acceleration, or uphill driving, which will deteriorate handling and stability.
