Yes, the AMG U88 system in the W465 G-Class helps reduce steering fatigue during long journeys by adjusting the steering effort based on driving conditions. The system's integration with the electric power steering (EPS) and adaptive handling systems allows it to modify the level of steering assistance, making the driving experience more comfortable over long distances. Here's how it works:

Key Features that Help Reduce Steering Fatigue:

1. Adaptive Steering Assistance:
   • The AMG U88 system utilizes dynamic steering assistance, which adjusts the level of steering effort based on factors like vehicle speed and the driving environment.
   • During long highway drives or at constant cruising speeds, the system can reduce steering effort, making the steering wheel lighter and easier to turn. This is especially useful for reducing the physical effort required by the driver when making small, continuous steering corrections, helping prevent fatigue over extended periods.
2. Speed-Sensitive Steering:
   • The U88 system integrates with the electric power steering (EPS), which is speed-sensitive. At higher speeds (such as on highways), the system increases steering weight to provide better stability and feedback, ensuring precise handling. However, at lower speeds, it lightens steering effort for easier maneuvering, especially when parking or driving in tight spaces.
   • On long journeys, when driving at constant high speeds, the lighter steering reduces the strain on the driver’s arms and shoulders, significantly contributing to a more relaxed driving experience.
3. Reduced Steering Effort at Low Speeds:
   • During city driving or when the vehicle is navigating slower, stop-and-go traffic, the system also adapts to reduce steering effort, making the steering feel less heavy. This further aids in minimizing fatigue in urban environments, where the driver would otherwise be making constant adjustments to the steering wheel.
4. Customizable Steering Settings (if available):
   • In some AMG models, the U88 system allows for the customization of steering feel through the vehicle's driving mode settings (e.g., Comfort, Sport, or Sport+). In Comfort mode, the system can soften the steering, further reducing effort and enhancing comfort during long-distance travel.
   • Drivers can adjust steering characteristics through the AMG Drive Unit or MBUX system to find a setting that best suits their personal preferences for reduced effort, making long drives more comfortable.
5. Efficient Handling on Long Journeys:
   • The U88 system works in tandem with other adaptive suspension and chassis systems to reduce unwanted vibrations and smooth out the ride. This ensures that the vehicle is more comfortable over long distances, indirectly contributing to a more relaxed driving posture and reducing strain on the driver.

Summary:

The AMG U88 system in the W465 G-Class helps reduce steering fatigue during long journeys by dynamically adjusting steering effort based on speed and driving conditions. It lightens the steering during constant cruising, increases assistance for high-speed stability, and allows for customizable settings to suit driver preferences. These features ensure a more comfortable and less tiring driving experience on extended trips, making long journeys more enjoyable and less physically demanding.
