They do, but the gas engines aren't as efficient as the diesels unless they are on flat roads and empty. My '14 1500 averaged about 17 mpg before the bigger tires. Now I'm at about 15 mpg with 33's. My commute has a ton of hills, so I rarely go into V4 mode.

My 2014 Ram 1500 averaged 20MPG on the way to Ocean City, Md, 140 miles away, with a car trailer, loaded. That's both ways.

Additionally, some of the newer diesels get 20+ mpg without a load, so they aren't much more expensive to run than a 4 door sedan.

Surprised to think a 2 tonne plus vehicle with a 6L engine could get 20mpg. Looking around the net real-world reports suggest on average people are getting about 14mpg.

That certainly reflects what other sites list as real-world highway figures. I doubt anyone gets that with a mix of urban, hauling stuff and deer trails.

Dropping back to less cylinders is a clever thing. I first heard of that in the Chrysler 300C. Does anyone know how it works? Does it alternate cylinders to share wear, or is there a primary vs secondary set of cylinders?
