Yes, the AMG Performance Steering Wheel in Mercedes-Benz G-Class models, especially those equipped with the W465 AMG Performance Steering Wheel, can indeed provide live feedback from AMG Performance diagnostics. This is made possible through the integrated telematics and performance monitoring systems that are embedded within the vehicle.

Key Features of AMG Performance Diagnostics Integration with the Steering Wheel:

1. Real-Time Performance Data:
   • The AMG Performance Steering Wheel allows the driver to access live performance diagnostics directly from the vehicle’s systems, including data on engine performance, turbo boost, torque delivery, g-forces, braking performance, and lap times (in track mode).
   • This information is displayed on the digital instrument cluster or central infotainment screen, but the steering wheel controls provide an easy way for the driver to switch between various performance metrics without taking their eyes off the road or track.
2. Performance Modes and Adjustments:
   • The steering wheel can be used to adjust AMG performance modes via the AMG Dynamic Select system, which is integrated with the car’s performance diagnostics. This allows drivers to select modes such as Race, Sport, and Comfort that adjust the car’s engine, suspension, and transmission settings, all based on real-time diagnostic feedback.
   • Each mode optimizes different aspects of the car’s performance, and the steering wheel can allow the driver to toggle between these modes while receiving immediate feedback about how each adjustment is impacting performance (e.g., changes in throttle response, gear shifting behavior, and handling characteristics).
3. Live Telemetry Data on Track:
   • When driving on a track or engaging in high-performance driving, the AMG Performance Steering Wheel can display live telemetry data like lap times, sector times, engine temperatures, boost pressure, and braking force in real time.
   • This data is crucial for track enthusiasts who want to monitor their performance and make adjustments on the fly. The steering wheel’s buttons can be used to scroll through different diagnostic metrics and select the data that the driver wishes to prioritize.
4. Visual and Haptic Feedback:
   • Some advanced models can also provide haptic feedback (vibrations) through the steering wheel to alert the driver about certain performance thresholds, such as approaching the maximum engine revs, the optimal shifting point, or reaching high temperatures in the braking system.
   • LED lights on the steering wheel (often around the rim) may light up to indicate when performance thresholds are being approached or exceeded, providing a visual cue without needing to look at the screens.
5. AMG Performance Analytics and Data Logging:
   • The AMG Performance Steering Wheel can interact with the MBUX system to track and record performance data, which can be analyzed later. For instance, the driver can review track performance data such as lap times, average speeds, or braking points through the car’s infotainment system, and the steering wheel may provide easy access to this data.
   • The steering wheel can also facilitate access to performance analytics like cornering speeds, engine torque curves, and acceleration times, helping drivers refine their technique or monitor the health of critical vehicle components over time.
6. Engine and Brake Diagnostics:
   • For drivers who are interested in performance details down to the engine health and brake performance, the steering wheel can access real-time diagnostic data related to these components, such as engine temperature, oil pressure, coolant temperature, and brake pad wear.
   • With performance-focused vehicles like the AMG G-Class, these diagnostics help ensure that the car performs optimally, even under demanding driving conditions.
7. Safety and Stability Features:
   • The steering wheel also provides feedback from stability control systems like AMG Traction Control and AMG Dynamic Cornering Assist. Through these systems, the steering wheel may provide live feedback about traction loss, wheel slip, or when the car is pushing beyond safe handling limits, alerting the driver to adjust driving behavior.

Conclusion:

The AMG Performance Steering Wheel in the Mercedes-Benz G-Class offers a powerful interface for live performance diagnostics and real-time feedback, making it a critical tool for performance-minded drivers. Whether on the road or the track, the ability to monitor engine health, lap times, traction, and other diagnostics right from the steering wheel enables the driver to optimize vehicle performance, adjust driving behaviors, and ensure the vehicle is functioning at its peak.
