GMs new 6.2 di seems to get great mpg
I have read a lot of owners reporting 16-18 average and 20-21 highway out of a 6.2. Any here have a new one?? MPG numbers please.

The new GM trucks are 600 lbs. lighter thanks to greater use of aluminum. Fuel is sent to fewer cylinders when the load is light on the engine. The trucks have 8-speed transmission with more overdrive gears and smaller gaps with the lower underdrive gears.
What surprises me is how infrequently the manufacturers of trucks and SUV's go for improving fuel economy. For the past 20 years the horsepower and 0-60 times have been the selling points to buyers. The people who cared about MPG bought a 45 MPG Prius or a 30 MPH Subaru Forester. I took a middle approach and have a 45 MPG Prius and a 15 MPG diesel truck. Guess which one I drive 80% of the time.
