In this paper, the acceleration performances of “Tesla Model S” and “Porsche Taycan” are compared. By comparing the acceleration performances of both electric vehicles, how the different motor characteristics affect the acceleration performance and maximum velocity, and why the “Porsche Taycan” uses a two-speed transmission are analyzed. As the vehicle starts, the “Porsche Taycan” uses the first speed gear, which offers a higher gear ratio than the “Tesla Model S”. Thus, the “Porsche Taycan” can use its maximum power of motor faster than the “Tesla Model S”. In addition, after the vehicle starts, the “Porsche Taycan” uses the second speed gear, which offers a lower gear ratio than the “Tesla Model S”. Thus, the “Porsche Taycan” shows a higher velocity than the “Tesla Model S”. Even though the “Porsche Taycan” uses a smaller maximum motor power(160 kW, 335 kW) than the “Tesla Model S”(193 kW, 375 kW), the “Porsche Taycan” shows similar acceleration performance and maximum velocity to the “Tesla Model S” because of the two-speed transmission. |
