In this video, Andre gets to drive from Indiana to Colorado in a 2020 Ram HD 2500 6.4L HEMI, while our 7.3L Ford F-250 provides backup. Initially, this trip was for a visit to Lippert Components in Indiana. At the time, Andre and the team opted to pick up a 2020 Ram HD 2500 6.4L and drive it back to Colorado.

This video is truly about the 2020 Ram HD 2500 6.4L Hemi, as it’s a vehicle many of you have asked for. It has the new eight-speed in it, and it has been updated a bit as well. Sure, we’ve tested a big HD Ram with a HEMI before, but that was a Power Wagon, which is a completely different vehicle than the HD we just got our hands on. This Ram is meant for towing and hauling unlike the off-road smashing the Power Wagon is built for.

During the trip, Andre noted the mileage on both vehicles and the results are interesting.

The 2020 Ford F-250 7.3L Gas

Our Ford F-250 project truck comes with Ford’s new 430 horsepower 7.3-liter gas V8 that makes 475 lb-ft of torque. It’s hooked up to a 10-speed automatic transmission and it has a 3.55 rear end. On top of that, our big Ford has much larger tires than stock along with a big lift.

With that in mind, we know that its efficiency has been compromised a bit. Especially when compared with a stock truck. Still, the real-world comparison is interesting for fans of both trucks.

Over 1,051.8 miles, our big Ford F-250 averaged 14.8 mpg.

The 2020 Ram HD 2500 6.4L Gas

The big Ram comes with FCA’s tried and true 410 hp 6.4-liter HEMI V8 that makes 429 lbs-feet of torque. It’s now hooked up to an eight-speed automatic transmission, as opposed to the old six-speed. It also has MDS (cylinder deactivation) grill shutters and a 3.73 rear end. All of those factors help a little bit with efficiency.

Over 1,051.8 total miles, the Ram averaged 15.4 mpg.

Now, we know that these trucks are very different. The Ram is more of a luxury hauler, while the Ford is more of a work truck. Still, they are both the beefiest gas V8 HD trucks we could pair and, honestly, both are damn impressive altogether.
