Vehicle design depends to a large extend on its intended use. Automobile for off-road use in countries that lack service facilities must be durable, simple systems with high resistance to severe overloads and extremes in operating conditions. Conversely, the customers for products that intended for the high-speed, limited-access road systems in Europe and North America expect more passenger comfort options, increased engine performance, and optimized high-speed handling and vehicle stability. Stability depends principally on the distribution of weight between front and rear wheels, the height of the centre of gravity and its position relative to the aerodynamic centre of the vehicle, suspension characteristics, and whether front or rear wheels are used for propulsion.
Weight distribution depends principally on the location and size of the engine. The common practice of front mounted engines exploits the stability that is more readily achieved with this layout. The development of aluminium engines and new manufacturing processes, have however, made it possible to locate the engine at the rear without necessarily compromising stability.

A bus is a self-propelled road vehicle, designed to carry more passengers than any automobile, generally on a fixed route. It was developed at the beginning of the 20th century to compete with streetcars by providing greater route flexibility. The bus was a natural outgrowth of the horse-driven coach. Today buses are defined as vehicles that accommodate more than 10 passengers.
There are four main types of buses: city or transit, suburban, intercity or tour, and school. The city bus operates within the city limits and is characterized by low maximum speed, low-ride platform, provision for standing and wheelchair passenger, two entrances on the curb side, low-back seats, and no luggage space.
The suburban bus is designed for short intercity runs and has high-back seats, luggage compartments and racks, and a single front entrance. The intercity type has a high-ride platform to provide maximum luggage space under the passengers, high-back seats, overhead luggage racks, individual reading lights, and a washroom. A typical intercity coach weighs about 26,000 pounds (12,000 kilograms), has a capacity of up to 47 passengers, a two-stroke-cycle diesel engine with up to 450 horsepower, an electronically controlled automatic transmission, and air brakes. School buses generally consist of a 50-passenger bus body, with special signal lamp and safety provisions, mounted on a long-wheelbase truck chassis.
Articulated buses were first used in Europe in the 1950s. In this arrangement a trailer body is connected to the rear of conventional front-engine bus by means of a hitch, a flexible diaphragm, and a continuous floor panel with accurate mating surface during turn manoeuvres. This arrangement permits up to a 75 percent increase in seating capacity and 20 percent improvement in fuel efficiency per seat-mile. The turning radius is the same as that of conventional bus. Manufacture of this design was begun in the United States in the 1980s by several European firms. Double decking, increased seating comfort and larger glass areas have been trends in tour buses, principally in Europe and Asia.
