The first cars, for the most part, hadDrive to the rear wheels. This was explained by the fact that in the early twentieth century it was constructively difficult to realize the idea of driving a controlled wheel in a mass car.
But in the 30s, front-wheel drive cars began to appear, which became popular in the 60s and 70s.
It is worth noting that modern technology,Helping the driver to drive the car, virtually equalize front-wheel and rear-wheel drive cars in both consumer qualities, and in safety and handling. Therefore, the choice between the front and rear drive is often determined by the class of the car: expensive cars have rear-wheel drive, budget cars - front.
In the conditions of mass productionFront-wheel-drive cars are cheaper than rear-wheel drive vehicles. Also, front-wheel-drive cars are fairly considered safer and better controlled during acceleration and uniform driving, it is easier to get out of the driveway on the front drives. In addition, front-wheel drive cars have slightly better cross-country - the driving wheels do not rest against the obstacle, but overcome it.
However, with a sharp acceleration of the car's weightRedistributed to the rear wheels. The front, driving wheels are unloaded, and the acceleration efficiency is reduced. When the gas pedal is pressed hard on the steering wheel, reactive forces can be transmitted under certain conditions, and the steering wheel can jerk quite hard. In conditions of icing, heavy rain, wet snow on the front drive, there is a danger of demolition, which is difficult to deal with unprepared driver. Therefore, on machines with front-wheel drive, it is recommended to enter the turns at a safe speed and carefully operate the gas pedal.
Less significant disadvantages of the front drive are lower reliability of the transmission unit design and more labor-intensive repairs, as well as limited turning angles of the front wheels.
As a rule, on rear-wheel drive vehiclesThe likelihood of skidding is higher than that of front-wheel drive vehicles. Consequently, they are considered less secure. Therefore, behind-wheel-drive foreign cars are equipped at the factory with various electronic systems that increase controllability. And the owners of the domestic rear-wheel drive "classics" just try not to accelerate on the ice and in heavy rain. It is for this reason that the statistics of hits in an accident are the same for cars with any type of drive. In addition, the already arisen skid on the rear-wheel drive car is more easily eliminated than on the front-wheel drive car. But for this, the driver needs to work out the skill of dropping the gas beforehand with automatic steering of the rudder in the direction of skidding. With sufficient preparation of the driver, on the rear drive it is easier to pass the turns in a controlled skid.
Less significant disadvantages of the rear drive -Higher car mass due to the cardan shaft, as well as a smaller useful floor space in the cabin due to the tunnel in which the same propeller shaft passes.
Summarizing all of the above, it can be noted that the front drive has the advantage on slippery roads, and the rear - on dry asphalt.
