audi's dakar car (the rs-q e-tron) proves that it's at least more efficient than petrol based competitors. it doesn't charge overnight so always uses the energy from onboard fuel tanks, which are smaller compared to the other competitors. it doesn't reach peak efficiency of course, but still uses less fuel overall.
