What are the differences and similarities between Mercedes-Benz 4-matic and Audi Quattro (Miscellaneous)

Mercedes-Benz 4-matic four Drive system has a century-old, Audi Quattro most advanced!
4Matic is a Mercedes-Benz automatic four-wheel drive system developed for the vehicle on slippery pavement.

Almost all Mercedes-Benz systems with the 4Matic system use standard automatic transmissions (in addition to the standard manual gearboxes in the 260 and 300 series and the 300D series cars with Diesel), which is why it is called 4Matic (automatic-four-wheel drive). The 4Matic system was first seen in the 1986 W124 series vehicles (Mercedes-Benz E-series). Paired with 2.6l,3.0l petrol engine, and diesel engine.

The 4Matic consists of a complex set of electronic systems to control the four-drive function. The system is mainly through the locking of the central differential and rear axle differential to achieve the additional grip on the slippery road surface. The central differential is the split box has two hydraulic clutch control power of the pre-and post-distribution ratio, a total of three operating mode 2WD, 4WD 35% before 65%, 4WD 50% before-50% after the computer according to the driver's choice and road conditions, such as automatic distribution of different modes to correspond. At the same time, if the rear wheel is still slipping after the central differential lock (4WD 50% front-50% rear mode), the rear axle lock will automatically lock to further enhance grip. Due to safety considerations, the front axle is not fitted with a differential lock. 4Matic computer According to the previous three ABS sensor signal comparison, the steering wheel angle and throttle size determines the timing of the differential lock should be involved. When the ABS braking system is turned on, the 4WD mode is automatically canceled. The first generation of W124 's 4Matic system engine throttle opening size control is not built into the computer.
There are two different 4Matic systems on the W124, the first set (1986-1991) uses a mechanical pressure lever to lift the device, and the second set (1992/1993) uses an electronic switch to remove the device. After 1993 years, Mercedes-Benz continued to produce and develop 4Matic systems on W124 because of the easy damage of the central differential.

The four-drive system was developed by the Austrian Steyr-daimler-puch and is also the production ground for the Mercedes G series. The second generation of the 4Matic system in the 1998/1999 years in the W210 vehicle system comeback. Produced by the Austrian Magna-steyr plant. The second generation of 4Matic uses a full-time quad drive four-wheel drive system, which uses an open differential (without any differential lock) before and after, and uses the ETS (Electronic Traction control system) with the ABS system and individual wheel proportional brakes to control the power output (brakes the skid wheel separately). The second generation system is much simpler than the first generation, and the system is also used in the Mercedes M-series RV.

At present, the second and third generation of 4Matic systems exist E-class, C-class, R-class, S-class, Viano and the entire Mercedes-Benz RV System. In addition to the second generation system, the third-generation system incorporates an automatic engine stabilization device.
