Nevertheless, depending on the sort of automatic transmission your Mercedes Classe S is equipped with you will have more or less reliability, we will expose them to you now:
- Classic automatic gearbox: It will use a torque converter, which will manage the gear changes, it’s the oldest technology, it has evolved a lot in the last decades (more gears and a better management of the gear changes).
- Robotized automatic gearbox: This is a manual gearbox with a robotized mechanism that will change the driver’s action. This sort of gearbox is less and less common because they are considered very slow. We also quite often feel a coupling during deceleration.
- Dual-clutch automatic transmission: This is the greatest automatic transmission, it works on the same principle as the robotic transmission, but thanks to its dual clutch, you won’t have any more problems with slow speeds or increased fuel consumption. They are often equipped on luxury models.
- Continuously variable automatic box: It is the same concept as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are really slow and often be unresponsive during the acceleration phases of your Mercedes Classe S.
