Why do Audi e-Tron electric cars require less maintenance than traditional cars?

I heard that electric cars require less maintenance, but I am curious as to why specifically Audi e-Tron cars require less maintenance compared to traditional cars.

Audi e-Tron cars are equipped with regenerative braking technology, which helps to reduce wear and tear on the brakes and prolong their lifespan.

Electric cars do not have complex engines with many moving parts, making them easier and less costly to maintain in the long run.

Audi e-Tron cars have a lower center of gravity due to the battery's placement, resulting in improved handling and less strain on the suspension system.
