The different sort of automatic gearbox of a Bmw Serie 7

Gearboxes have the advantage of being known to be solid, as you don’t need to use your clutch pedal and everything is electronically and mechanically controlled there will be no early wear of your clutch or other components that could be put to the test by misuse on your part.
Nevertheless, based on the sort of automatic transmission your Bmw Serie 7 is equipped with you will have more or less reliability, we will present them to you now:

  • Common automatic gearbox: It will use a torque converter, which will manage the gear changes, it’s the oldest technology, it has evolved quite 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 system that will change the driver’s action. This sort of gearbox is less and less basic because they are thought to be very slow. We also quite often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the greatest automatic transmission, it functions 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 elevated fuel consumption. They are often fitted on luxury models.
  • Continuously variable automatic box: It is the same principle 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 Bmw Serie 7.
