2020 1500 Duramax 100 Mile MPG Tow Test

Not really impressed with 10.7 mpg.

I’m getting more impressed with this engine. Granted I can’t use a 1/2 ton at this time, but if I needed one, this truck would be the first on my list.

Impressive results and great video. We wish we had been able to get that performance when we were towing. Thanks.

I know time will tell on this engine/transmission combo. But GM did a smart thing by going the inline 6 route. I’m sure it will go over the 150k, just the belt needs replaced... overall I’m watching the market on these 1/2 ton diesel trucks. I’m wondering how strong and long the market will be for these trucks. I see the advantage of owing one one day, when we downsize from the large fifth wheel. Chevy should have put a much large Fuel tank in their truck... good grief the tank is about the size of my 69 C10...

Imagine how good the mileage would have been if he hadn't been doing 70 the whole time.

I was thinking the same thing.

I also can't believe he was originally towing that trailer with a Colorado.

I think you are not alone a lot of baby boomers will downsize and won't need a 3/4 or 1 ton. It nice to have to have choices from the big three.
