The 2020 Ram Rebel Diesel vs 2020 GMC Sierra 1500 Diesel – both are epic!

You might think that the 2020 Ram Rebel Diesel vs 2020 GMC Sierra 1500 Diesel would be a tough one to call. You would be correct, they are remarkably close in content, ability and tech. What separates them is a different philosophy in power-trains and off-road setups.

While we all have our preferences, it wasn’t that easy to choose between the two. They represent the best of what Ram and GMC can build and it shows.

The heavily revised EcoDiesel returns with some impressive numbers. The 3.0-liter turbo diesel V6 makes 260 horsepower and 480 lbs-feet of torque. It hooked up to an eight-speed automatic transmission and four-wheel drive. It also has a electronically locking rear differential, something the GMC doesn’t have.

Our 2020 Ram 1500 Rebel Crew Cab 4×4 diesel has an MSRP of $70,880. This is a fully loaded truck with the EcoDiesel costing a whopping $4,995. At that price, a well optioned heavy duty diesel is a realistic buy as well.

The GMC sports GM’s brand spankin’ new “baby” Duramax 3.0-liter inline-6 turbo diesel. It makes 277 hp and 460 lb-ft of torque.That extra horsepower is noticeable as the GMC feels quicker than the competition off the line. It’s hooked up to a 10-speed automatic transmission.

The GMC has the Eaton G80 automatic locking rear axle. It works on its own, but (in our opinion) is less effective off-road than a electronically locking rear axle.

The 2020 GMC Sierra 1500 4WD Crew Cab AT4 diesel has an MSRP of $65,800. While it is a great deal less expensive than the Ram, it is not quite as loaded as the FCA product either. Plus, its Duramax diesel is only a $2,495 option – considerably less than Ram’s EcoDiesel option.

Both vehicles are fitted with off-road goodies including higher ground clearance, off-road tires, suspension and armor to boot. They also have trick tailgates that some may find utilitarian, while others may not. All in all, both trucks represent the best of what Ram and GMC can put inside of a 1/2-ton diesel 4X4 and we’re impressed.
