| A '''three wheeled car''' is an ] typically having one ] in the front for steering and two at the rear for power. This reduces the cost of the steering mechanism but greatly increases instability when braking. However, a breed of ] having two wheels in the front and one wheel at the back has ] among automotive designers and enthusiasts. One advantage of this configuration is improved ], and another is that it readily enables small lightweight motorcycle powerplants and indeed rear wheels to be used. This approach was used by the BMW ] and the ] T60 | |||
| For the lowest ] (and best ]) a rain drop shape is desired. The ] of the water in the rain drop as the air moves past it (or the drop moving through still air) naturally creates this low resistance shape. As the drop begins to fall, the force of the air pushes and distorts the drop. If the force is less in any place, the drop expands in that area. If the force is high in one spot, that spot is pushed in. | |||
| A rain drop is wide and round at the front, tapering to a point at the back. The three wheel configuration allows the two front wheels to create the wide round surface of the vehicle. The single rear wheel allows the vehicle to taper at the back. | |||
| The disadvantage of a non-tilting three wheel configuration is ] - the car will tip over in a turn before it will slide, unless the ] is much closer to the ground or the wheelbase is much wider than a similar four wheel vehicle. To improve stability some three wheelers are designed as ]s so that they lean while cornering like a motorcyclist would do. The tilt may be controlled manually or by computer. | |||
| In at least some ] states, three wheeled cars are regulated as ] with similar ] requirements. | |||
