  • Robotized automatic gearbox: This is a manual gearbox with a robotized system that will replace the driver’s action. This sort of gearbox is less and less basic because they are viewed as very slow. We as well often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the best automatic transmission, it works on similar principle as the robotic transmission, but thanks to its dual clutch, you won’t have any more complications with slow speeds or increased 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 often be unresponsive during the acceleration phases of your Lexus RX.
