They drop to 4, but they are still much bigger engine

As I said, I drove a Chevy aveo on the highway and only got 28 mpg, and that was going no higher than 80, because I wasn't too confident in it above that.

My dad has driven just about every rental car you can imagine (Kia's, hynduais, chevys, fords, mazdas, etc) over the past 9 months making the same drive from the Kansas City Airport to Topeka, and he has told me that he gets almost the same mileage from everything he drives whether they be 6 cylinders or 4 cylinders. Like I said in my very first post, technically I got better mileage with the smaller engine, but I don't see an extra 2 or 3pmg as that big of a deal when you consider the performance tradeoffs that usually accompany it. The worst mileage he has gotten is in a Kia Rondo.

Hell, I drive my Nissan Xterra with its 3.3L V6 on the highway and get around 14-15mpg. My mom's Lexus GX470 with the 4.7L V8 and gets 18-21 mpg.


I will put this disclaimer on everything I have said: When you start going above 65mph, wind resistance, rpms, etc start to play a much bigger role in what kind of mileage you can get out of a given engine. Perhaps if I (or my dad) drove more slowly, we would see more pronounces mpg gains in the smaller engines.
