Understand the different Mercedes-Benz 4MATIC all-wheel drive systems
November 18 2024,
Mercedes-Benz’s 4MATIC all-wheel drive (AWD) systems are renowned for enhancing traction, stability, and driving dynamics across various models. These systems are tailored to meet the specific performance and handling requirements of different vehicle categories, including standard Mercedes-Benz models, high-performance AMG variants, the iconic G-Class, and the latest electric vehicles (EVs). This article delves into the distinct types of 4MATIC systems available in Canada, providing a comprehensive understanding of their functionalities and applications.
1- Mercedes-Benz 4MATIC Systems
The standard 4MATIC system is engineered to improve traction and handling across a range of driving conditions. It operates by distributing torque between the front and rear axles, adapting to road surfaces and driving dynamics. This system is available in two primary configurations:
- Permanent 4MATIC All-Wheel Drive: This setup maintains a constant torque distribution between the front and rear axles, typically in a 45:55 ratio. It’s designed for models like the E-Class and S-Class sedans, providing balanced handling and enhanced stability.
- Variable 4MATIC All-Wheel Drive: Utilized in models such as the A-Class and CLA, this system primarily operates in front-wheel drive under normal conditions to optimize fuel efficiency. It can seamlessly transfer up to 50% of torque to the rear wheels when needed, ensuring optimal traction on slippery surfaces.
2- Mercedes-AMG 4MATIC+ Systems
The AMG Performance 4MATIC+ system is tailored for high-performance AMG models, delivering dynamic handling and superior traction. This fully variable AWD system can distribute torque between the front and rear axles from 100% rear-wheel drive to a 50:50 split, depending on driving conditions and selected driving modes. This adaptability enhances cornering performance and straight-line acceleration.
In certain AMG models, such as the E 63 S, the system includes a “Drift Mode,” which disengages the front axle, allowing for rear-wheel-drive dynamics suited for track use. This feature underscores the system’s versatility in delivering both everyday drivability and high-performance capabilities.
3- Mercedes-Benz G-Class 4MATIC System
The G-Class, known for its off-road prowess, features a robust 4MATIC system designed to tackle challenging terrains. This system includes a permanent AWD setup with a 40:60 front-to-rear torque distribution, complemented by three fully locking differentials (front, centre, and rear). These locking differentials can be engaged manually to ensure maximum traction in extreme off-road conditions.
Additionally, the G-Class is equipped with a low-range gear reduction, enhancing torque delivery for steep inclines and difficult terrains. This combination of features makes the G-Class’s 4MATIC system exceptionally capable in both on-road and off-road environments.
4- 4MATIC Systems in Mercedes-Benz Electric Vehicles
In Mercedes-Benz electric vehicles, the 4MATIC system is adapted to the unique characteristics of electric drivetrains. These systems typically employ dual electric motors—one on each axle—to provide AWD capabilities. The torque distribution between the axles is managed electronically, allowing for instantaneous adjustments based on driving conditions.
For instance, the EQE 500 4MATIC Sedan features dual permanently synchronous electric motors with a combined output of 300 kW. The electrified AWD system can adapt in milliseconds, optimizing traction and handling. Additionally, available features like 4-wheel steering can further enhance maneuverability and stability.
Similarly, the EQB 350 4MATIC SUV utilizes an all-electric, all-wheel-drive system that balances power delivery between the front and rear motors. This setup ensures efficient performance and improved handling across various road conditions.
Understanding the nuances of Mercedes-Benz’s 4MATIC systems allows drivers to appreciate the tailored engineering that enhances performance, safety, and driving pleasure across different models and driving scenarios.
