The W465 AMG Performance Steering Wheel is not necessarily exclusive to the AMG G63 variant, but it is most commonly found in AMG-branded models of the Mercedes-Benz G-Class lineup, particularly in the G63. However, it can also be found in some other AMG models or high-performance variants of the G-Class if equipped with an AMG performance package or similar trim.

Here's a breakdown of the steering wheel's availability:

1. AMG G63: The W465 AMG Performance Steering Wheel is typically standard in the G63, as it aligns with the performance and sportier characteristics of this variant. It provides the driver with a more dynamic, performance-oriented feel that complements the G63's power and handling capabilities.
2. Other AMG G-Class Models: In certain cases, the W465 AMG Performance Steering Wheel might also be available as an option or as part of a performance package on other G-Class models that are tuned or designed with an AMG-focused design, though the G63 remains the most likely model to feature it as standard.
3. Non-AMG G-Class Models: The standard G-Class models (like the G500, G350d, etc.) typically do not come with the AMG Performance Steering Wheel. However, it may be possible to retrofit or upgrade to this steering wheel via the Mercedes-Benz dealership or aftermarket, though it may require additional adjustments to be fully compatible with non-AMG G-Class models.

Summary:

While the W465 AMG Performance Steering Wheel is most commonly associated with the AMG G63, it is not strictly exclusive to that variant. It may be available in other AMG-equipped G-Class vehicles or offered as an upgrade/option depending on the model and market. Non-AMG G-Class variants generally do not come with this steering wheel unless upgraded.
