To allow off-road and deep snow capability, Four-Wheel Drive is standard on the Gladiator. But it costs extra on the Canyon.

To help make backing safer, the Gladiator Overland/Rubicon’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Canyon doesn’t offer a cross-path warning system.

Both the Gladiator and the Canyon have standard driver and passenger frontal airbags, front side-impact airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available collision warning systems, blind spot warning systems and rear parking sensors.


The Gladiator’s corrosion warranty is unlimited miles longer than the Canyon’s (unlimited vs. 100,000 miles).

There are over 37 percent more Jeep dealers than there are GMC dealers, which makes it easier should you ever need service under the Gladiator’s warranty.


A hardened steel chain, with no maintenance needs, drives the camshafts in the Gladiator’s engine. A rubber cam drive belt that needs periodic replacement drives the Canyon’s camshafts. If the Canyon’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

The Gladiator has a solid front axle with a floating power axle for durability that the Canyon 4x4’s independent front suspension and exposed front driveshafts don’t offer.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Jeep vehicles are better in initial quality than GMC vehicles. J.D. Power ranks Jeep 17th in initial quality. With 3 more problems per 100 vehicles, GMC is ranked 20th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Jeep vehicles are more reliable than GMC vehicles. Consumer Reports ranks Jeep 3 places higher in reliability than GMC.


The Gladiator’s 3.6 DOHC V6 produces 85 more horsepower (285 vs. 200) and 69 lbs.-ft. more torque (260 vs. 191) than the Canyon’s standard 2.5 DOHC 4 cyl.

The Gladiator’s 3.0 turbo V6 diesel produces 79 more horsepower (260 vs. 181) and 73 lbs.-ft. more torque (442 vs. 369) than the Canyon’s 2.8 turbo diesel.

Fuel Economy and Range

In heavy traffic or at stoplights the Gladiator’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Canyon doesn’t offer an automatic engine start/stop system.

The Gladiator has a gallon more fuel capacity than the Canyon (22 vs. 21 gallons), for longer range between fill-ups.


The Gladiator offers a manual transmission for better acceleration, control and fuel economy. The Canyon doesn’t offer a manual transmission.

Brakes and Stopping

For better stopping power the Gladiator’s brake rotors are larger than those on the Canyon:




Front Rotors

12.9 inches

12.2 inches

Rear Rotors

13.6 inches

12.75 inches

The Gladiator’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Canyon are solid, not vented.

Tires and Wheels

For better traction, the Gladiator Rubicon’s tires are larger than the largest tires available on the Canyon (285/70R17 vs. 265/70R16).

For better ride, handling and brake cooling the Gladiator has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Canyon.

The Gladiator has a standard full size spare so a flat doesn’t interrupt your work or a trip. A full size spare costs extra on the Canyon Without the option you must depend on a temporary spare, which limits mileage and speed before replacement.

Suspension and Handling

The Gladiator has standard front and rear stabilizer bars, which help keep the Gladiator flat and controlled during cornering. The Canyon’s suspension doesn’t offer stabilizer bars.

The Gladiator Rubicon has an active front sway bar, which helps keep it flat and controlled during cornering, but disconnects at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Canyon doesn’t offer an active sway bar system.

The front and rear suspension of the Gladiator uses coil springs for better ride, handling and control than the Canyon, which uses leaf springs in the rear. Coil springs compress more progressively and offer more suspension travel for a smoother ride with less bottoming out.

For a smoother ride and more stable handling, the Gladiator’s wheelbase is 9 inches longer than on the Canyon Short Box Crew Cab (137.3 inches vs. 128.3 inches).

For better handling and stability, the average track (width between the wheels) on the Gladiator is 1.3 inches wider in the front and 1.3 inches wider in the rear than the track on the Canyon.

Cargo Capacity

A low lift-over bed design makes loading and unloading the Gladiator easier. The Gladiator’s bed lift-over height is 29.7 inches, while the Canyon Extended Cab’s liftover is 34.2 inches. The Canyon Crew Cab’s liftover is 34.5 inches.

The Gladiator’s cargo box is larger than the Canyon Crew Cab’s in almost every dimension:




Length (short/long)



Max Width



Min Width






A standard locking glovebox, standard locking center console and optional locking under seat storage keeps your small valuables safer in the Gladiator. The Canyon doesn’t offer locking storage for small valuables.

Payload and Towing

The Gladiator’s standard towing capacity is much higher than the Canyon’s (4000 vs. 3500 pounds).

The Gladiator has a higher standard payload capacity than the Canyon (1600 vs. 1424 lbs.).


The Gladiator’s available front power windows lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Canyon’s passenger windows don’t open automatically.

The Push Button Start standard on the Gladiator allows you to start the engine without removing a key from pocket or purse (Gladiator Overland/Rubicon’s optional Passive Entry will also allow unlocking the driver’s door without taking your keys out). The GMC Canyon doesn’t offer an advanced key system.

The Gladiator’s speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Canyon’s manually variable intermittent wipers have to be constantly adjusted.

The Gladiator’s optional dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Canyon doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the Gladiator offers an optional Adaptive Speed Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Canyon doesn’t offer an adaptive cruise control.

The Gladiator offers an optional 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Canyon doesn’t offer a house-current electrical outlet.
