Why do the Audi e-Tron's brake lights not work during regenerative braking?

I have noticed that when driving my e-Tron and lifting my foot off the accelerator, the brake lights do not activate. Is this normal and if so, why?

Yes, this is normal for the e-Tron. The regenerative braking system only activates the physical brakes when necessary. This helps preserve brake pad life and improves the efficiency of the vehicle.

The e-Tron's brake lights only activate when using the physical brakes. Regenerative braking does not require the use of the brakes, so the lights do not turn on. This is a common feature in many electric vehicles.

To ensure the safety of other drivers on the road, it's best to manually activate the brake lights when lifting your foot off the accelerator during regenerative braking. You can do this by lightly pressing on the brake pedal. This will signal to other drivers that you are slowing down.
