As we all know, these three four-wheel drive systems are the specialty capabilities of the German Troika.
1. Let’s talk about Audi’s Quattro system first.
As the core of Quattro full-time four-wheel drive, the Torsen center differential adjusts the distribution of front and rear axle forces faster than any electronic control technology. The power of the engine can always be effectively distributed to the four wheels, and combined with the Torsen mechanical center differential, it ensures road grip on the four tires. The Torsen differential used allows a certain speed difference between the front and rear axles to avoid traditional four-wheel drive interference. Even if the speed difference is too large, that is to say, a wheel is slipping, Torsen will rely on its own mechanical characteristics to restrain it and prevent the wheel from slipping.
2. Next is BMW’s XDRIVE system
The core technology of the XDRIVE all-wheel drive system is the transfer case developed by Magnus Starr in Austria, which can continuously adjust torque distribute. The xDrive system continuously changes torque distribution according to road conditions and delivers the required torque to the front and rear wheels respectively. By default, front-to-rear torque distribution is 40:60, and the maximum front-to-rear torque distribution ratio is between 0:100 and 100:0. Torque distribution can be completed in less than 0.1 seconds.
3. Finally, Mercedes-Benz’s 4MATIC system
4MATIC’s all-wheel drive is compact, lightweight, and also optimizes friction. Compared with other all-wheel drive systems , which has advantages in terms of weight, fuel consumption, comfort, and safety in passive conditions. Depending on the engine version, this latest offering in all-wheel-drive technology results in a weight of only 66 to 70 kilograms compared to a conventional rear-wheel drive system.
Which of Audi, BMW and Mercedes-Benz has the most advanced four-wheel drive technology?
They are all dry goods at the bottom of the box, each with its own strengths. If we really want to score 1.2.3 names, Audi's Quattro will be ranked first in total points. It is no exaggeration to say that when driving on the highway at a speed of 120 kilometers per hour, water suddenly appears. The Audi four-wheel drive system transmits torque to the rear wheels at the moment when the front wheels pass through the water. The rear wheels pass through the water, and the white chess piece can pass through. There are gaps, but not Mercedes-Benz. It's not that Mercedes-Benz is bad, but its own design. He was destined not to react so quickly. Because of different research directions, Mercedes-Benz is better than the other two in terms of escape performance. Audi's four-wheel drive has too much technological involvement and we don't have the pleasure of control, but it's powerful. On the track, almost no car can beat the RS6. Stupid, fast and fast. Due to different research and development directions, Mercedes-Benz and BMW ranked second.
