How does the Audi e-Tron achieve such a high range on a single charge?

I've heard the Audi e-Tron can travel up to 400 km on a single charge. What technology allows it to achieve this impressive range?

The Audi e-Tron utilizes a high-voltage 95-kilowatt battery, which is capable of storing and delivering large amounts of energy efficiently.

In addition to the powerful battery, the e-Tron also utilizes regenerative braking technology, which allows the car to recapture energy and store it back into the battery while driving.
