What is the efficiency rating of the Audi e-Tron?

I'm trying to decide if buying an electric car is worth it in terms of cost savings. I've heard that the Audi e-Tron is highly efficient, but I want to know the specific efficiency rating to compare it to other electric cars.

The Audi e-Tron has an impressive efficiency rating of 88 miles per gallon equivalent (MPGe). This is much higher than most other electric cars on the market.

As an electric car owner myself, I can attest to the cost savings. Not only do you save on gas, but maintenance costs are significantly lower as well.
