Three Wheel Electric Car

A three wheeled car, also known as a tricar or tri-car, is an automobile having either one wheel in the front for steering and two at the rear for power, two in the front for steering and one in the rear for power, or any other combination of layouts. Due to its handling superiority, an increasingly popular form is the front-steering "tadpole" or "reverse trike" sometimes with front drive but usually with rear drive.



Early car pioneer Karl Benz developed a number of three-wheeled models. One of these, the Benz Patent Motorwagen, is widely regarded as the first purpose-built automobile, and may be the first petrol car driven on British soil, in 1894. In 1896, John Henry Knight showed a tri-car, recognized as the first British-made motorcar, at The Great Exhibition.



Having one wheel in front and two in the rear for power reduces the cost of the steering mechanism, but greatly decreases stability. However, a configuration of two wheels in the front and one wheel at the back has many strong proponents among automotive designers and enthusiasts. Two advantages are its improved aerodynamics, and that it readily enables small lightweight motorcycle powerplants and rear wheels to be used. This approach was used by the BMW Isetta. Alternatively, a more conventional front-engine, front wheel drive layout as is common in four-wheeled cars can be used, with subsequent advantages for stability and traction.
