Yes, both leather and Alcantara materials used in the W465 AMG Performance Steering Wheel are designed to be resistant to UV rays. This ensures that the materials maintain their appearance, feel, and performance over time, even with prolonged exposure to sunlight.

UV Resistance for Leather:

1. UV-Resistant Coatings: High-quality leather used in AMG steering wheels often comes with UV-resistant coatings that protect it from the harmful effects of ultraviolet rays. UV rays can cause leather to fade, dry out, or crack. These coatings help maintain the leather's color and prevent degradation caused by sun exposure.
2. Vegetable-Tanned Leather: Leather that undergoes vegetable tanning (commonly used in high-end automotive applications) naturally tends to be more resilient to environmental factors, including UV damage. Although it's not immune to fading, the tanning process enhances its longevity and UV resistance.
3. Surface Treatments: To further protect the leather, AMG may use specific surface treatments to ensure the material remains moisture-resistant and color-stable under sun exposure.

UV Resistance for Alcantara:

1. UV Stabilizers: Alcantara is inherently more resistant to UV rays compared to traditional fabrics or some types of leather. However, to further protect the material from color fading or fiber degradation, UV stabilizers are often added during production. This ensures that Alcantara retains its luxurious, suede-like texture and vibrant color even after long periods of exposure to the sun.
2. Microfiber Structure: Alcantara is made of microfibers, which are highly resistant to the damaging effects of UV radiation. The fibers are strong and colorfast, meaning they are less likely to degrade or lose their color when exposed to sunlight.
3. UV-Resistant Coatings: Just like leather, Alcantara materials used in high-performance vehicles like AMG steering wheels may also receive additional coatings that provide extra UV protection. These coatings help shield the material from the harsh effects of the sun, ensuring it remains looking pristine.

Conclusion:

Both leather and Alcantara materials used in AMG steering wheels are treated to be UV-resistant. Special coatings and stabilizers are applied to prevent damage from the sun, including fading, drying, and degradation. This enhances the longevity of the materials, keeping the steering wheel looking and performing like new, even with frequent exposure to sunlight.
