  • Dual-clutch automatic transmission: This is the greatest automatic transmission, it works on similar concept as the robotic transmission, but thanks to its dual clutch, you won’t have any more complications with slow speeds or elevated fuel consumption. They are often equipped on luxury models.
  • Continuously variable automatic box: It is similar concept as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are especially slow and tend to be unresponsive during the acceleration phases of your Mercedes Classe M.
