Abstract :Vehicle simulations have a very important place in the automotive R&D process. These simulations provide automotive companies with the benefits of saving money on model creation and the user changing many parameters throughout the vehicles as soon as possible. In this study, the engine and powertrain energy losses of a 4-stroke gasoline passenger car were investigated in FTP75 insert ignore into journalissuearticles values(Federal Test Procedure);, HFET insert ignore into journalissuearticles values(Highway Fuel Economy Test);, US06 and WLTP insert ignore into journalissuearticles values(Worldwide Harmonized Light Vehicles Test Cycles); cycles, in urban and extra-urban conditions. examined physically and by testing with the help of GT-Suite vehicle simulation program. Ac-cording to the analysis results, the lowest CO2 emission insert ignore into journalissuearticles values(127.58 g/km); and average fuel consumption insert ignore into journalissuearticles values(5.29 l/100km); were obtained in the HFET driving cycle. While the transmission and gear friction values were close to each other between the driving cy-cles, the lowest loss in terms of torque converter losses was obtained in the HFET driving cycle insert ignore into journalissuearticles values(0.2%);.
