22 MPG from a late model Hemi car? Even with all those electronics and shutting off 4 cylinders on the highway?

I should have added that was 4 people, a dog and luggage all the way to the ceiling in my Magnum. Granted if it was me alone it would have been a lot better but I do agree with your post.

It's not hard to find 50s and early 60s cars that will do 20 MPG highway and weigh 4000 lbs; look at some of the Mobil Economy Run winners over the years. They drove those cars carefully and tuned them special to set those figures, but as a direct comparison in '60 Pontiac won using a Catalina with the 8.6:1 389 and got around 21 MPG; my '60 Catalina with the 10:1 motor would do 18 on the highway no problem - and not being babied, either. Imagine the same motor with a manual OD trans in a 2800-lb car instead of a 4100-lb car with an automatic transmission.

Now those economy run cars had 2bbl carbs, no power steering, air conditioning, power windows, or any of the toys the late model does, but they were still pleasant to drive.

I think it's just a matter of having a motor that makes a lot of torque on the low side of the RPM band, so it can overcome the air resistance and so forth that wants to keep a car from moving, without a lot of RPM. I suppose if you could build a 4-cyl that was still around 350-400 CI, it might make enough torque to be efficient... but otherwise, leave them to the econoboxes.

The wife's car is a '06 Charger Daytone R/T Special Edition. It is also driven daily and she gets 22-25 mpg. You don't even know when it drops those 4 cyl. It also kicks them back in so fast you don't even know it also.
