2021 Mercedes-Benz GLS vs 2022 GMC Yukon

The 2021 Mercedes-Benz GLS, a continuation of the third generation introduced in 2020, was a luxurious SUV that offered a blend of elegance and practicality. Originally launched as the GL-Class in 2006, it was designed to replace the G-Class, but the latter's popularity ensured its survival. The GLS, with its three rows and plush interior, became a family-friendly alternative to the Navigator and Escalade. The transition from "GL" to "GLS" during its second generation marked a shift towards a more refined design. Despite its size, the GLS appeared less bulky than its predecessors, thanks to softened angles and clever design elements. Inside, the GLS boasted a futuristic cabin dominated by a massive digital screen, emphasizing its tech-centric approach. Available in three trims—GLS 450, GLS 580, and the high-performance AMG GLS 63—the GLS offered a range of features, from remote keyless entry to a 13-speaker Burmester sound system. Various packages allowed for further customization, enhancing comfort and style.

In contrast, the 2022 GMC Yukon was a bold statement in chrome, especially in its Denali trim. The Yukon, with its distinctive grille and C-shaped headlights, exuded a commanding presence. The Denali's front was a chrome masterpiece, while the AT4 trim offered a rugged look with a dark grille and skid plate. Inside, the Yukon provided a spacious cabin with seating for up to nine, depending on the configuration. The Denali trim featured luxurious touches like heated and cooled front seats and unique interior designs. The AT4, with its Jet Black interior and Brandy accents, catered to off-road enthusiasts. The Yukon's redesign improved third-row legroom significantly, making it more comfortable for passengers. The power-folding second-row seats and power-retractable assist steps added convenience, while the pushbutton transmission controls modernized the driving experience.

The 2021 Mercedes-Benz GLS offered a range of powerful engines, starting with the GLS 450's twin-turbocharged 3.0-litre inline-six, producing 362 horsepower and 369 pound-feet of torque.

The AMG GLS 63, with its hand-crafted 4.0-litre twin-turbo V8, generated an impressive 603 hp and 627 lb-ft of torque. This powerhouse could accelerate from 0 to 100 km/h in just 4.2 seconds, reaching a top speed of 280 km/h. The GLS's EQ Boost 48-volt mild-hybrid system added an extra 21 hp and 184 lb-ft of torque when needed, enhancing performance and efficiency. The adaptive air suspension and multiple drive modes allowed for a customizable driving experience, while the GLS's handling defied its size, offering a smooth and agile ride.

The 2022 GMC Yukon provided three engine options, including a 5.3-litre V8 with 355 hp and 383 lb-ft of torque, standard on all trims except the Denali.

A 3.0-litre turbodiesel engine, available on most trims, offered 277 hp and 460 lb-ft of torque, with excellent fuel efficiency. All engines were paired with a 10-speed automatic transmission. The Yukon's 4WD system, with a two-speed transfer case on the AT4 and Denali, provided off-road capability. The AT4's approach angle and skid plate enhanced its ruggedness. The Yukon's towing capacity reached 3,810 kg with the right configuration. The independent rear suspension improved ride quality and handling, though some bouncing was noted on rough surfaces. The optional air ride adaptive suspension further enhanced comfort, especially on highways.

The 2021 Mercedes-Benz GLS offered three rows of spacious seating, with ample headroom and legroom for first- and second-row occupants. The standard seven-passenger configuration could be reduced to six with optional second-row captain's chairs. The third row, while not as roomy, accommodated full-size adults comfortably. The GLS provided 355 litres of cargo space behind the third row, expanding to 1,209 litres with the third row folded, and 2,400 litres with both rear rows down. The power-folding third row and numerous storage compartments added convenience, though the centre console was somewhat limited in size.

The 2022 GMC Yukon, with its redesign, significantly improved third-row legroom, offering 886 mm of space. The increased wheelbase and length, along with the independent rear suspension, contributed to the Yukon's spaciousness. Cargo capacity behind the third row grew to 722 litres. The power-folding second-row seats and power-sliding centre console added practicality, while the power-retractable assist steps facilitated entry and exit. The pushbutton transmission controls modernized the interior, though they required some acclimation.
