2021 Mercedes-Benz G-Class vs 2021 GMC Yukon

The 2021 GMC Yukon was a testament to GMC's commitment to offering a rugged yet refined SUV. Positioned between Chevrolet and Cadillac, the Yukon provided a premium experience without the plushness of a Buick. The redesigned model was available in various trims, including the new AT4, which catered to off-road enthusiasts with features like skid plates and all-terrain tires. However, the Denali trim was the most popular, offering a luxurious experience with its exclusive dashboard design, real wood trim, and leather-wrapped panels. The Yukon Denali Ultimate, with its Midnight Blue paint and 22-inch wheels, stood out with its upscale appearance, although it came with a hefty price tag.

The 2021 Mercedes-Benz G-Class, or G-Wagen, was a blend of ruggedness and luxury. Its boxy, retro design was a nod to its military origins, yet it had become a status symbol among the elite. The G-Class was available in two models: the G550 and the AMG G63, both offering extensive customization options through the G Manufaktur Program. Inside, the G-Class featured a tasteful design with a 12.3-inch widescreen infotainment system and a matching virtual instrument panel. Despite its luxurious appeal, the G-Class remained a capable off-road machine, with features like adjustable suspension and three locking differentials.

The 2021 GMC Yukon offered three engine options, with the Denali trim featuring a 420-horsepower 6.2-liter V8 engine. This engine, paired with a ten-speed automatic transmission, delivered robust acceleration and a satisfying V8 burble. However, fuel economy was not its strong suit, with an average of 14.4 mpg on a testing loop. The Yukon boasted an independent rear suspension and an available Four-Corner Air Ride suspension, enhancing ride quality and handling. The Active Response 4WD system, with its electronic limited-slip differential, improved cornering and traction. The Yukon Denali could tow up to 8,400 pounds with 2WD, though this was less than its predecessor.

The 2021 Mercedes-Benz G-Class G550 was powered by a twin-turbocharged 4.0-liter V8 engine, producing 416 horsepower and 450 lb-ft of torque. It featured a nine-speed automatic transmission and permanent 4WD, allowing it to sprint from 0 to 60 mph in 5.6 seconds. The G-Class had a double-wishbone independent front suspension and a rigid rear axle, providing a supple ride on pavement. With a turning circle of 44.6 feet and impressive off-road angles, the G550 was both nimble and capable. The AMG G63 variant offered even more power, with 577 hp and 627 lb-ft of torque, achieving 0 to 60 mph in 4.5 seconds.

The 2021 GMC Yukon benefited from a new independent rear suspension, significantly improving passenger and cargo space. The front seats, though comfortable, lacked a massage function, and the upper door panel edges were hard. The second-row seats slid and folded flat, enhancing comfort and cargo room. The third-row seat offered improved thigh support, accommodating adults comfortably. Cargo volume was impressive, with up to 122.9 cubic feet available in the standard Yukon and 144.7 cubic feet in the Denali XL.

The 2021 Mercedes-Benz G-Class G550 offered a spacious and luxurious interior. The front cabin featured comfortable seats and ample storage, while the tall roofline provided excellent headroom. The second row accommodated three adults comfortably, with a 60/40 split-folding design. The G550 had a cargo capacity of 38.1 cubic feet behind the third row, expanding to 68.6 cubic feet with the second row folded. It could tow up to 7,700 pounds, thanks to its body-on-frame construction. However, some luxury features, like ventilated seats, were only available in expensive packages.

The 2021 GMC Yukon Denali featured a 10.2-inch touchscreen infotainment system with wireless Apple CarPlay, Android Auto, and Amazon Alexa integration. Upgrades included wireless charging, a navigation system, and a 14-speaker Bose audio system. The Rear Seat Media system, with dual 12.6-inch displays, offered entertainment options, though it required some setup for streaming content. The Yukon also had a 15-inch head-up display and multiple camera views for enhanced maneuverability.

The 2021 Mercedes-Benz G-Class G550 boasted twin 12.3-inch HD screens for the instrument panel and infotainment system. These customizable screens, combined with ambient lighting and a Burmester Surround Sound system, created an immersive experience. The COMAND system, with unique Touch Control buttons on the steering wheel, offered intuitive control. The G550 included WiFi, Bluetooth, Apple CarPlay, and Android Auto, though it lacked wireless charging.

The 2021 GMC Yukon came equipped with numerous advanced driving assistance systems, including forward collision warning, automatic emergency braking, and lane-keeping assistance. The Denali trim offered adaptive cruise control and enhanced emergency braking. The ADAS operated smoothly, providing a safe and comfortable driving experience. Crash-test ratings were unavailable, but the Yukon's size offered inherent safety advantages.

The 2021 Mercedes-Benz G-Class G550 featured a range of safety systems, such as a rearview camera, active brake assist, and adaptive cruise control. However, the active lane-keeping assist was somewhat intrusive, requiring careful engagement. The G-Class had not been rated by the IIHS or NHTSA, but its size and construction provided safety benefits in certain crashes.
