Why is differential fluid important in an Audi R8?

I want to know the specific reasons why differential fluid is important in maintaining the performance and longevity of an Audi R8.

Differential fluid plays a crucial role in the internal components of your vehicle's differential, keeping them lubricated and preventing excessive friction and wear. Regular differential fluid changes are necessary to maintain optimal performance and extend the lifespan of your Audi R8.

The differential is responsible for transferring power from the engine to the wheels. If the fluid is old or contaminated, it can cause damage to the differential and result in costly repairs. It's important to regularly check and change the differential fluid in your Audi R8 to keep it running smoothly.
