Off-road, the GMC Sierra AT4 versus the Ram Rebel Rouser was epic!
During our episodic adventures with our project Ram truck, we never quite had a comparison as interesting as the GMC Sierra AT4 vs the Ram Rebel Rouser. Sure, they are in slightly different categories on paper as the GMC Sierra AT4 is a little bit more luxury/tech based. It also has the beefy 6.2-liter V8 and a 10-speed automatic transmission. It’s a bit higher scale, one might say – but it’s closer than you think.
One quick note: Yes, we know the Ram Power Wagon is better off-road, but it’s not part of this series. Also, yes, we know that the Chevrolet Trail Boss will have a 6.2-liter V8 soon, but it was not available when we did this comparison.

GMC Sierra 1500 AT4:
The GMC Sierra AT4 has a meaty 6.2-liter V8 that makes 420 horsepower and 460 lbs-feet of torque. It’s hooked up to a 10-speed automatic transmission and it has four-wheel drive. Unlike the Ram Rebel’s electrically locking rear differential, which is activated by the driver, the AT4 has a G80 rear differential. This is an “anti spin” automatic locking rear differential that requires a bit of spinning before it locks up.
The GMC Sierra AT4 4X4 with the 6.2 V8 base price is $57,290. Our tester in this video came out to about $66,000.
Ram Rebel:
While the Ram Rebel comes with a 5.7-liter V8 that makes 395 hp and 410 lb-ft of torque, it also has the e-Torque system. This makes it a mild hybrid as the system helps motivate the Ram from a stop, conserving fuel. It doesn’t appear to help overall horsepower or torque. The Ram Rebel has an eight-speed automatic transmission. The standard axle has a 3.92 rear axle ratio.
Base price for the Ram Rebel (e-Torque) 5.7 V8 4X4 is: $51,330. With all of the accessories and upgrades, the Ram Rebel Rouser is pushing the bank at just over $70,000.
This was a great matchup because both vehicles excelled t some tings without being too dominate in any category. While the Ram Rebel Rouser is excellent off-road and has the slight edge, the GMC Sierra AT4 is outstanding on the highway – where it has a slight edge. Both trucks are comfortable, easy to drive and tons of fun, but which one is better altogether?
You might be surprised after you see them both off-road.
