What is e-tron technology in the Audi A1?

I've read about e-tron in other Audi models, but I'm unsure of what it specifically entails in the A1. Can someone explain what e-tron actually does in this specific car model?

The e-tron technology in the Audi A1 is a hybrid system that combines an electric engine with a traditional combustion engine. This allows for increased fuel efficiency and reduced emissions.

From my experience, the e-tron technology in the Audi A1 works seamlessly to provide a smooth and efficient driving experience. It transitions between electric and combustion modes seamlessly with no noticeable lag.
