How does the range extender function work in the Audi e-Tron?

I've heard that the Audi e-Tron has a range extender feature. Can you explain how it works and how it differs from a regular electric car's range?

The range extender in the Audi e-Tron is a gasoline-powered engine that acts as a backup generator for the battery. It kicks in when the battery is low, allowing you to continue driving until you can recharge the battery.

Compared to other electric cars, the Audi e-Tron's range extender provides a longer driving distance before needing to recharge. It also allows for more flexibility when planning longer trips.

My personal suggestion is to only use the range extender when necessary, as relying on it too often can increase fuel costs and decrease the car's overall efficiency. It's best to use it as a backup and charge the battery regularly.
