What is the real-world fuel economy for a new 2020 Ford F-250 Super Duty with a 3rd generation 6.7-liter turbo-diesel V8 that is mated to the new 10-speed automatic transmission? We did a real-world test, see the results below.
We recently received this question from Nathan L.
“I am really impressed with the new 2020 Chevy Silverado HD with the 6.6 Duramax diesel and how your 1,000 mile trip reported a 19.9 mpg. I am just wondering when and if you guys will be doing the same test with the 2020 Ford F-250 Power Stroke diesel. I am currently in the process of looking at purchasing a new three quarter ton diesel pickup, and I tow only 25% of the time and have a long commute to work. I was curious if you guys would be willing to do a 1,000 mile trip to have a better comparison in the two pickups.”
We did not drive another 1,000 miles in a new 2020 Ford Super Duty diesel, but we did drive over 330 miles from Colorado to Moab, UT. We measured the fuel economy at the pump. You can watch in the video below.
The truck we drove was a 2020 F-250 crew cab 4×4 Tremor off-road truck. The Tremor has a factory suspension lift and rides on 35-inch all-terrain tires.
In the end, the 2020 Ford clocked in 19.2 MPG. This is fairly impressive when you consider the added drag of the heavier off-road version of the truck. The 2020 GMC Sierra 2500 HD diesel showed 19.8 MPG.
We will be doing more testing with a more standard 2020 Super Duty trucks in the future.
