The electric pickup truck market is growing quickly, with the upcoming Chevy Silverado EV, GMC Sierra EV, Ram 1500 REV, and Tesla Cybertruck about to expand this market. Currently, the GMC Hummer EV and Rivian R1T are the top off-road electric pickup trucks. Let’s see how they compare.

Does the Rivian R1T have more power than the GMC Hummer EV SUT?

The Rivian R1T and GMC Hummer EV SUT are in competition for off-road shoppers looking for an electric adventure truck for some fun out in the wilderness. In a comparison of power, we see that the Hummer is more powerful than the R1T. Here are the baseline power stats:

Horsepower600 hp1,000 hp
Torque600 lb-ft11,500 lb-ft
Payload Capacity1,384 lbs1,300 lbs
Towing Capacity11,000 lbs7,500 lbs

These figures tell us the GMC electric truck is more powerful than the Rivian model, but the R1T carries more and can tow more than the Hummer EV SUT. Both trucks have AWD/4WD setups with power at both axles. However, the R1T is available with four electric motors in higher trims.

Which electric truck is more spacious?

The GMC Hummer EV SUT is one of the largest vehicles in the electric vehicle market, toppling the scales at more than 9,000 pounds. On the flip side, the Rivian R1T fits in the midsize category of pickup trucks. This should offer distinct space advantages in favor of the GMC, though that makes it less efficient regarding fuel economy.

Rear headroom38.1 inches38.6 inches
Rear legroom46.6 inches38.9 inches

Bed Length54.1 inches60.1 inches

As you can see, the Hummer is larger than the R1T across the board, offering a more spacious cabin and larger bed, giving the GMC a clear lead in this competition.

The off-road chops of the GMC Hummer EV and Rivian R1T

Before we get to the special off-road features of each electric pickup, let’s take a moment to compare the ground clearance and off-road angles of each pickup.

Ground Clearance8.7 inches10.1 inches
Approach Angle35.5 degrees49.7 degrees
Departure Angle30.0 degrees38.4 degrees

The GMC Hummer EV stands higher off the ground than the Rivian R1T initially. However, the air suspension of the Rivian truck can be adjusted for up to almost 15 inches of ground clearance, making the model preferable for deep off-road adventures with its short wheelbase and excellent angles. However, the Hummer EV includes features that make it easy to drive around obstacles at angles (Crab Walk) and extreme torque to push through any challenging terrain.

How far can you go in these electric trucks?

The dual-motor layout of the Rivian R1T offers 270 miles of electric driving when the batteries are fully charged. It takes 13 hours to charge these batteries full using a 240-volt at-home charger. If a level 3 charger is used, the R1T can reach 80% capacity in less than 40 minutes. However, other available battery packs can boost the range to 352 or 410 miles.

Turning to the tri-motor GMC Hummer EV SUT, the new estimated maximum driving range, according to Car and Driver, is 381 miles. The large Ultium battery pack takes 10.5 hours to recharge at a Level 2 charger and only 30 minutes when plugged into a Level 3 DC fast charger.

The fuel mileage equivalent for these two electric pickup trucks is 73 MPGe for the R1T and 53 MPGe for the Hummer EV truck. This means the Rivian is more efficient than the GMC, which makes sense due to the Hummer’s massive size and weight.

Price and warranty info for the Hummer and R1T EVs

The 2023 GMC Hummer electric pickup truck starts at $96,550 and comes with a three-year/36,000-mile basic warranty along with an eight-year/100,000-mile battery warranty.

The 2023 Rivian R1T starts at $73,000 and has a better warranty than the GMC. Rivian gives this electric truck a basic warranty that covers it for five years/60,000 miles, while the EV battery warranty covers eight years/175,000 miles.

Which of these electric pickup trucks should you drive?

The 2023 Rivian R1T and GMC Hummer EV SUT are impressive off-road-focused electric trucks. The Hummer is bigger, more powerful, and packed with cool features that make it fast (0-60 mph sprint of 3.0 seconds) and comfortable. The R1T fits in the midsize class, has better off-road stats, a much better warranty, and a lower starting price. The R1T also comes with a gear tunnel between the bed and cab, offering some added storage space for off-road enthusiasts.

In this comparison, the R1T is the better overall choice for most truck shoppers. Though, the Hummer EV sure makes a statement on the road.
