The rise of electric car technology on the world market induces the small recreational go-karts industry to follow similar paths. The trade of recreational gokarts with electric motorization already exists but is still incipient. The electric drive in the go-kart would provide, among other advantages, the possibility of insertion of known automotive technologies, such as an Anti-lock Braking System and a Stability Control System. The successful insertion of these technologies into a gokart would be a very significant breakthrough for a product that has undergone modest technological advances since its inception. However, to obtain the technological success of traditional go-kart, the electric model depends on the application of modern methods of engineering and metrology, such as computerized mathematical modeling, the main objective of this dissertation. Thus, this dissertation initially presents the physical and dynamic characteristics of a combustion driven go-kart, obtained through tests and measurements made on track and bench. The Alfano (registered) Pro III Evo equipment, whose indications were submitted to simplified validation procedures, was used as the main measuring instrument. Based on the experimental data, Matlab / Simulink (registered) computerized mathematical models simulating the dynamic behavior of the go-kart were then developed, and the results of the simulations were compared to the results of the measurements made on the track for validation purposes. The combustion propulsion of the validated computational model was then replaced by electric propulsion, and simulations of the new model were performed, allowing the observation of the simulated dynamic behavior of an electric go-kart.
