Of course they are!
law of conservation of energy:
The extra mass to move the car is only relevent in a minor increase of rolling resistance - EVs recharge around 60% of the kinetic energy. ICE vehicles don‘t, they convert the kinetic enegry into heat via brakes!
ICE engines generate 70-80% heat and only 20-30% of the energy in fuel is transferred into kinetic energy - at best.
