Because of the higher ground clearance, BMW 5 series can perform better on bad roads - it can go over higher obstacles and bumps. At the same time, the higher ground clearance can reduce stability and handling on paved roads, especially at higher speeds. Note, however, that this BMW 5 series version does not have 4x4 drive, which is very important in poor road conditions.
