The following article aims to compare the performance parameters between a continuously variable transmission (CVT) and a 6-gear manual transmission. The manual transmission is a usual type of transmission system, consisting in a clutch and a transmission gearbox, containing a set of gears which, according to the coupling chosen, creates a reduction between the speed of the engine and the gearbox output. Meanwhile, the continuously variable transmission (CVT) is a type of transmission that outputs any reduction, between certain limits, in a continuous way, from two pulleys linked through a metallic belt. Due to the characteristics of both transmission systems, it is possible to infer that there are differences on the vehicle’s performance. The comparison between both types of transmissions, applied to a passenger’s vehicle is done through the mathematical modeling considering the same usage profile. Thus, parameters such as vehicle speed, traveled distance, engine speed and transmission reduction were obtained by the dynamic computational analysis and compared, explicating advantages and disadvantages of each system.
