Compare the2027 GMC Yukon VS 2026 Mercedes G-Class

Both the Yukon and G-Class have child safety locks to prevent children from opening the rear doors. The Yukon has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G-Class’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Yukon has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The G-Class doesn’t offer front seat center airbags.

Both the Yukon and the G-Class have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning, available all-wheel drive and driver alert monitors.

GMC’s powertrain warranty covers the Yukon 1 year and 10,000 miles longer than Mercedes covers the G-Class. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the G-Class ends after only 4 years or 50,000 miles.

The Yukon’s corrosion warranty is 1 year longer than the G-Class’ (6 vs. 5 years).

There are over 4 times as many GMC dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Yukon’s warranty.

The G-Class’ redline is at 6800 to 7200 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Yukon has a 5100 to 5800 RPM redline.

J.D. Power and Associates’ 2025 Initial Quality Study of new car owners surveyed provide the statistics that show that GMC vehicles are better in initial quality than Mercedes vehicles. With 11 fewer problems per 100 vehicles, JD Power ranks GMC higher than Mercedes.

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that GMC vehicles are more reliable than Mercedes vehicles. J.D. Power ranks GMC above average in long-term dependability. With 62 more problems per 100 vehicles in the first three years of ownership, Mercedes is rated below average.

The Yukon’s 3.0 turbo diesel produces 82 lbs.-ft. more torque (495 vs. 413) than the G 550’s standard 3.0 turbo 6-cylinder hybrid.

On the EPA test cycle the Yukon gets better mileage than the G-Class running its gasoline engine:

G-Class
	AWD	550 4.0 turbo V8	17 city/19 hwy
		63 4.0 turbo V8	14 city/16 hwy

To lower fuel costs and make buying fuel easier, the GMC Yukon uses regular unleaded gasoline (premium recommended with the 6.2 V8 engine for maximum performance). The G-Class requires premium, which can cost on average about 84.9 cents more per gallon.

The Yukon has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The G-Class doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the GMC Yukon, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the G-Class.

For better stopping power the Yukon’s brake rotors are larger than those on the G-Class:

	Yukon	G 550	AMG G 63
Front Rotors	16.1 inches	13.9 inches	15.7 inches

For better traction, the Yukon has larger standard tires than the G-Class (275/60R20 vs. 265/60R18).

For better ride, handling and brake cooling the Yukon has standard 20-inch wheels. Smaller 18-inch wheels are standard on the G-Class. The Yukon Denali’s optional 24-inch wheels are larger than the 21-inch wheels optional on the AMG G 63.

The GMC Yukon’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes G-Class only has 5 wheel lugs per wheel.

The Yukon has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The G-Class doesn’t offer vehicle monitored tire inflation.

All Yukon’s have standard full size spares so a flat doesn’t interrupt your trip. A full size spare is not available on the G-Class 580 Without it you must depend on roadside assistance and your vehicle will have to be towed.

For superior ride and handling, the GMC Yukon has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Mercedes G-Class has a solid rear axle, with a non-independent rear suspension.

The Yukon AT4/Denali has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The G-Class doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Yukon’s wheelbase is 7.1 inches longer than on the G-Class (120.9 inches vs. 113.8 inches).

For better handling and stability, the track (width between the wheels) on the Yukon is 3.7 inches wider in the front and 3.4 inches wider in the rear than the average track on the G-Class.

The Yukon’s front to rear weight distribution is more even (50% to 50%) than the G-Class’ (48% to 52%). This gives the Yukon more stable handling and braking.

The Yukon Denali 4x4 handles at .69 G’s, while the G 550 pulls only .62 G’s of cornering force in a Motor Trend skidpad test.

The Yukon Denali 4x4 executes Motor Trend’s “Figure Eight” maneuver quicker than the G 550 (29.3 seconds @ .58 average G’s vs. 29.8 seconds @ .58 average G’s).

For better maneuverability, the Yukon Denali Ultimate w/24” wheels’ turning circle is 3.5 feet tighter than the AMG G 63’s (40.8 feet vs. 44.3 feet).

For greater off-road capability the Yukon AT4 Ultimate Air Ride has a greater minimum ground clearance than the G 580 (10 vs. 9.8 inches), allowing the Yukon to travel over rougher terrain without being stopped or damaged.

For excellent aerodynamics, the Yukon has standard flush composite headlights. The G-Class has recessed headlights that spoil its aerodynamic shape and create extra drag.

The front grille of the Yukon uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The G-Class doesn’t offer active grille shutters.

The Yukon offers optional seating for 8 passengers; the G-Class can only carry 5.

The Yukon has 61.3 cubic feet more passenger volume than the G-Class (168.3 vs. 107).

The Yukon has .4 inches more front headroom, 5.8 inches more front legroom, 4.6 inches more front hip room, 7.7 inches more front shoulder room, 2.5 inches more rear legroom, 4.1 inches more rear hip room and 7.3 inches more rear shoulder room than the G-Class.

The Yukon’s cargo area provides more volume than the G-Class.

	Yukon	G-Class
Third Seat Folded	72.5 cubic feet	n/a
Third Seat Removed	n/a	37.4 cubic feet
Second Seat Folded	122.8 cubic feet	68.6 cubic feet

Pressing a switch automatically lowers the Yukon’s second and third row seats, to make changing between passengers and cargo easier. The G-Class doesn’t offer automatic folding second row seats.

The Yukon’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The G-Class’ swing out door blocks loading from the driver’s side.

To make loading and unloading groceries and cargo easier, especially for short adults, the Yukon has a standard power liftgate, which opens and closes automatically by pressing a button, or on the Yukon AT4/Denali, by just waiting momentarily behind the back bumper, completely leaving your hands free. The G-Class doesn’t offer a power cargo door.

The Yukon’s minimum standard towing capacity is much higher than the G-Class’ (7700 vs. 7000 pounds). Maximum trailer towing in the Mercedes G-Class is only 7000 pounds. The Yukon offers up to a 8400 lbs. towing capacity.

The Yukon has a much higher standard payload capacity than the G-Class (1510 vs. 1235 lbs.).

The Yukon’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The G-Class does not have an oil pressure gauge.

The Yukon offers an optional heads-up display that projects speed, warning, navigation instruction, infotainment and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The G-Class doesn’t offer a heads-up display.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Yukon’s available exterior PIN entry system. The G-Class doesn’t offer an exterior PIN entry system, and its Mercedes-Benz Emergency Call can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

To improve rear visibility by keeping the rear window clear, the Yukon has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the G-Class only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Yukon’s standard side window demisters help clear frost or condensation from the side windows in the winter. The G-Class doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Yukon has standard extendable sun visors. The G-Class doesn’t offer extendable visors.

Optional air conditioned front and second row seats keep the Yukon’s passengers comfortable and take the sting out of hot leather in summer. The G-Class doesn’t offer air-conditioned seats in the rear.

Both the Yukon and the G-Class offer available massaging front seats. The Yukon Denali Ultimate also offers optional massaging second row seats in order to maximize comfort and eliminate fatigue on long trips. Massaging rear seats aren’t available in the G-Class.

The Yukon has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The G-Class doesn’t offer a house-current electrical outlet.

The Yukon is available in both rear-wheel drive and four-wheel drive configurations. The G-Class doesn’t offer a two-wheel drive configuration.

J.D. Power and Associates rated the Yukon first among large suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The G-Class isn’t in the top three.

The GMC Yukon outsold the Mercedes G-Class by almost 8 to one during 2025.
