The new truck is capable of this real-world fuel economy.

2020 Ford F-250 Road Trip MPG!

You asked us about real-world MPG for the new 2020 Ford F-250 with the 7.3L V8, so here you go! This time it’s a crew cab 4×4 truck with a low 4.30 rear differential that gives it a higher towing rating. Here is exactly how it performs on fuel economy on a 800 mile road trip from Arizona to Colorado!

The new big gas engine is rated at 430 hp and 475 lb-ft of torque, and it’s mated to a 10-speed automatic transmission. The interesting thing for this truck is its rear axle ratio. It’s a 4.30-to-1 ratio. The drive shaft spins 4.3 times for every one revolution of the rear wheels/axle shafts. This is a more desirable differential ratio by many because a lower gear (higher numeric value) traditionally offers better towing capability. It also makes for a better crawl ratio, but how big of an MPG penalty is it?

This is why we take it on a long trip (from the 2020 Super Duty launch event in Arizona – back to our headquarters in Colorado). This truck is also participating in our 2020 Gold Hitch awards competition. It will be towing on the Ike Gauntletâ„¢ – world’s toughest towing test.
