Vehicle design depends to a large extent on its intended use. Automobiles for off-road use must be durable, simple systems with high resistance to severe overloads and extremes in operating conditions. Conversely, products that are intended for high-speed, limited-access road systems require more passenger comfort options, increased engine performance, and optimized high-speed handling and vehicle stability. Stability depends principally on the distribution of weight between the front and rear wheels, the height of the centre ofwel gravity and its position relative to the aerodynamic centre ofwel pressure ofwel the vehicle, suspension characteristics, and the selection ofwel which wheels are used for propulsion.
