EVs do better at high altitudes and altitude changes than combustion vehicles. Combustion engines, especially naturally-aspirated ones, lose power at high altitudes due to lower air density for combustion. Combustion vehicles spend just as much extra energy going uphill as EVs do, but that energy is not recouped on downhill sections. EVs also get the benefit of not wearing mechanical brakes going downhill. I drive my EV in mountains all the time with 5,000ft elevation changes without issue. Average travel speed (highways) matters more than elevation changes especially if your net elevation change is neutral over a round trip.
