How is the range of the Audi e-Tron affected by different road surfaces?

I am planning on purchasing an Audi e-Tron and am curious about the impact that various road surfaces can have on its range. For example, does driving on a smooth highway result in better range than driving on a bumpy backroad?

The range of the Audi e-Tron can be affected by different road surfaces, but it is not a major factor. Driving on a smooth highway may result in slightly better range, but the difference will not be significant.
