The updating of automotive driving cycles to encompass contemporary driving conditions and conducting driving tests with these cycles hold significant importance in determining vehicle performance. In this study, engine performance and vehicle energy losses of a passenger- type vehicle with a gasoline internal combustion engine were examined in 2 different driving cycles of the new generation with the help of the GT-SUITE vehicle simulation program. All parameters of the vehicle and the driving cycle were defined with the help of the simulation program. According to the simulation results, the number of gear changes and transmission losses were higher in the Artemis driving cycle, which had a higher average acceleration (0.62 m/s²) and deceleration (-0.56 m/s²) acceleration, along with it. Torque converter losses were 4.73 times less in the Artemis cycle, where the torque converter locking clutch was used in greater quantities. The high average acceleration also increases tire and braking losses. When a comparison was made in terms of vehicle energy losses, it was found that Artemis driving cycle losses were 22% higher. When the driving cycles are compared in terms of specific fuel consumption, a specific fuel consumption of 386.7 g/kWh was obtained in the Artemis driving cycle and 548.9 g/kWh in the WLTC driving cycle.
