Is it true that a bigger car runs better than a small one at high-altitude?

Question

I rented a car from Enterprise in Albuquerque, NM last week. I booked a compact car with a GPS system on their website. A few weeks later at the time of pick-up I was told that they do not have any GPS system available. Instead they recommended Standard or Full Size without a GPS system. A woman at the counter said that a bigger car might cost me more, but I end up saving on gas at this high-altitude. Is it true? The total cost was about the same as my original booking, but I just wonder if I was ripped off by unnecessary upgrade. Any input please?

Answer 1

dont really understand your question, but a bigger car does run better than a small car because it has more mass in high altitude and most big cars have decent big engines, so it helps them even more.

Answer 2

Bigger cars have bigger engines and suspensions. Regardless of the altitude, bigger cars run better than smaller ones. Just a piece of advise: turn off the AC when climbing to a higher altitude, it will save you 25% gas consumption.
