Abstract

The existing gear ratio on vehicles has several weaknesses, one of them is speed limitation. The purpose of this study aims to examine the effect of gear ratio to speed on vehicles. The vehicle's gear ratio will be changed to produce speeds exceeding the existing speed of Mercedes units. This unit is used as a fire truck at the airport. To achieve this, an analytical method with several equations is used. The Allison 4000 series is the most suitable transmission for the unit based on the speed output produced. The results of the analysis showed a significant increase in the maximum speed, from 133.27 km/h to 162.39 km/h, there was an increase of 21.85%.
