What is the best BMW drivetrain? And Why


What is the best BMW drivetrain?

BMW cars according to the type of drive are divided into the following types:

front-wheel drive;

rear-wheel drive;

all-wheel drive.

Consider each type of drive separately

Front-wheel drive

By front-wheel drive is meant such a distribution of engine thrust to the chassis, in which only the front axle plays the leading role.

Despite the fact that front-wheel drive began to be widely used on cars much later than rear-wheel drive, nevertheless, today almost all budget cars use this type.

Front wheel drive benefits:

  1. the engine compartment has decreased due to the transverse arrangement of the engine;
  2. managed to get rid of fairly heavy parts, like a driveshaft and rear axle;
  3. increased trunk volume;
  4. increased the amount of usable space in the cabin;
  5. the car can be made shorter;
  6. greater stability during acceleration on slippery roads, compared to rear-wheel drive.
  7. acceleration on a slippery road does not require the driver to level the car, front-wheel drive, in this regard for beginners, is less problematic.

Disadvantages of front-wheel drive:

  1. Redistribution of mass during movement. During acceleration, most of the mass is distributed to the rear axle, thereby unloading the front axle and traction, therefore, is reduced. Because of this, the problem of slippage during hard acceleration for front-wheel drive models is very relevant.
  2. A smaller angle of rotation, due to the connection of the wheels to the front differential through a CV joint (constant velocity joint).
  3. Rapid wear of the front brake pads compared to the rear.
  4. When a skid begins on a slippery road, braking leads to an unstable trajectory. For stability, the front axle must continue to work, and most drivers ignore this fact and continue to apply the brakes.
  5. The inability to use it on trucks, where the greatest load falls on the rear axle, with the exception of a very small number of experimental models that have not found their mass production.

Rear drive

Rear-wheel drive or classic drive has been used on cars almost from the very first production models. Its principle is based on the transmission of engine torque to the rear axle, usually by means of a shaft and a rear axle, with the exception of a small number of models when the engine was at the rear.


  1. Significantly higher grip due to the redistribution of the car’s mass to the rear during acceleration. Due to this, it is possible to obtain better acceleration with less engine power. This is especially noticeable on climbs, where front-wheel drive models look worse.
  2. Although skidding on a slippery road can occur much earlier than on a front-wheel drive, nevertheless, the alignment of the car occurs by simply releasing the gas, which is logical for most drivers.
  3. Very effective “engine braking” when the gas is released and the car can reduce the speed without “skid” even on a rather slippery road.
  4. Smaller turning radius due to lack of CV joints.
  5. Great flotation on loose roads, when the front wheels prepare the rut and the driven rear wheels work more efficiently.
  6. And, of course, with rear-wheel drive, you can do anything with the car in terms of controlled drifting.


  1. With a very small mass of the car and an unloaded rear axle, there is not enough grip when driving on ice.
  2. Rear-wheel drive requires the driver to behave correctly when a skid begins, that is, the steering wheel must be turned in the direction of the skid, and not vice versa.
  3. The luggage compartment and the interior space of the car are reduced.

Four-wheel drive

All-wheel drive means such a connection of torque to the chassis when it is distributed to two axles. This is the best type of drive on a car, due to the fact that it has all the advantages of front and rear drive.


  1. Sustainability. All-wheel drive BMWs are very stable on the road in any weather and on any road surface.
  2. Acceleration is almost completely devoid of slippage, due to the even distribution of grip on all wheelsets.
  3. Versatility. All BMWs with all-wheel drive have a controlled rear axle connection, and some have all-wheel drive on demand, that is, you can drive either rear-wheel drive or front-wheel drive. The choice of connecting the bridge depends on the situation and the desire of the driver
  4. Efficient driving on a winding road, which, together with the stability control system, simply works wonders.


There are practically no operational shortcomings in all-wheel drive vehicles. But there are others:

  1. Price. Providing all-wheel drive requires additional devices to ensure its proper functioning, such as a transfer case, which is quite vulnerable during “active” driving.
  2. The mass of the car, which increases due to additional elements.
  3. The requirements for the body are increasing. Naturally, a car with two leading axles should be stronger. Hence, the thickness of the metal and the design requirements also change.
  4. The body structure is much more complicated, which should “not notice” the rear-wheel drive.

From the above, it can be seen that such a BMW can no longer meet the budget option and its cost will be much higher. Therefore, only middle and upper class models are equipped with all-wheel drive.

Our preferences look like this:

Four-wheel drive. He definitely gets 1st place.

Front-wheel drive and rear-wheel drive have about the same number of advantages and disadvantages, so they both take an honorable second place.
