2020 Cadillac XT6 vs 2021 Mercedes-Benz G-Class

The 2020 Cadillac XT6 presented a clean and crisp exterior, embodying modern Cadillac design. Its long, boxy shape was cleverly disguised under smooth body panels and limited creases, giving it a tailored appearance. The XT6 avoided flashy chrome and oversized elements, opting instead for satin-painted silver accents and a medium-sized silver mesh grille. The vehicle's thin LED headlights and vertical running lamps added a touch of flair, while maintaining a sense of restraint and taste. Inside, however, the XT6 fell short compared to its competitors. Despite having soft leather and gold-tinted carbon fiber trim, the interior lacked the luxurious feel expected from a brand-new luxury car. The seats were thin and plain, and the use of cheap vinyl in certain areas detracted from the overall experience. The XT6's interior seemed outdated, especially when compared to the more lavish offerings from other luxury brands.

In contrast, the 2021 Mercedes-Benz G-Class, known as the G-Wagen, boasted a rugged and retro exterior design that stood out in the Mercedes-Benz lineup. Its boxy shape and straight body lines were reminiscent of its military origins, giving it a unique appeal. 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 screen and a matching virtual instrument panel. The cabin's ambient lighting could be coordinated with the instrument panel colors, creating a personalized atmosphere. Despite its luxurious features, the G-Class remained a capable off-road vehicle, appealing to both the adventurous and the status-conscious.

The 2020 Cadillac XT6 was powered by a 3.6-liter V6 engine, producing 310 horsepower and 271 pound-feet of torque. While it was sufficient for moving the vehicle and towing up to 4,000 pounds, the engine was coarse-sounding and less responsive compared to newer turbocharged V6 engines. The XT6 featured a 9-speed automatic transmission with quick shifts and well-spaced ratios. Front-wheel drive was standard, but all-wheel drive and adaptive dampers provided a balanced and controlled ride. The steering was direct and nicely weighted, with a sport mode offering a more secure feel. Despite its size, the XT6 handled well, thanks to its well-tuned steering and suspension. However, it lacked advanced suspension options like height-adjustable air springs, which were available in some competitors. The XT6 achieved an EPA combined rating of 20 mpg, with AWD models rated at 17 mpg city and 24 mpg highway.

The 2021 Mercedes-Benz G-Class, specifically the G550 model, was equipped with a twin-turbocharged 4.0-liter V8 engine, delivering 416 horsepower and 450 pound-feet of torque. This powerful engine allowed the G550 to accelerate from 0 to 60 mph in just 5.6 seconds. The G550 featured a nine-speed automatic transmission and permanent four-wheel drive, with Dynamic Select driving programs for various conditions. The G-Class had a robust suspension system, including double-wishbone independent front suspension and a rigid rear axle, providing a smooth ride on pavement and impressive off-road capabilities. The G550's off-road prowess was further enhanced by its adjustable suspension, damping options, and three independent locking differentials. The AMG G63 variant offered even more power, with 577 horsepower and 627 pound-feet of torque, achieving a 0 to 60 mph time of 4.5 seconds. However, the G-Class had lower fuel economy ratings, with the G550 achieving 13 mpg city and 19 mpg highway.

The 2020 Cadillac XT6 offered a spacious interior, with a third-row seat that was surprisingly accommodating for adults. The second-row captain's chairs or bench seat provided ample space, and the standard panoramic moonroof added to the sense of openness. The XT6 featured a 3-zone climate control system and optional heated cushions and backrests. Cargo space was generous, with 12.6 cubic feet behind the third row, 43.1 cubic feet with the third row folded, and 78.7 cubic feet with both the second and third rows down. Visibility was excellent, aided by a digital mirror with a widescreen camera. The XT6's controls were user-friendly, with an improved touchscreen infotainment system and an alternative rotary controller.

The 2021 Mercedes-Benz G-Class, particularly the G550, offered a roomy and luxurious interior. The front cabin featured comfortable seats and ample storage options, while the tall roofline provided excellent headroom. The second row was spacious, with a 60/40 split-folding seatback and bottle pockets in the rear doors. The G550 had a cargo capacity of 38.1 cubic feet behind the third row and 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 front seats, were only available as part of expensive packages. The G550's spare tire was mounted on the tailgate, adding to its distinctive styling.

The 2020 Cadillac XT6 featured an infotainment system that was a significant improvement over its predecessor. It offered cloud-based voice commands, a built-in app store, and driver profiles that could be transferred to other GM vehicles. Apple CarPlay and Android Auto were standard, along with a suite of driver assists. Optional features included 360-degree cameras and night vision. However, the XT6 lacked some advanced tech features, such as Super Cruise and a reconfigurable digital instrument panel. The Bose stereo and infotainment screen were also considered mediocre for the segment.

The 2021 Mercedes-Benz G-Class impressed with its twin 12.3-inch HD screens for the instrument panel and infotainment system. These screens were customizable and could be coordinated with the cabin's ambient lighting. The G550 featured the latest COMAND system, with unique Touch Control buttons on the steering wheel for easy navigation. A rear-seat entertainment system was available, and the G550 came with multiple USB and 12-volt outlets. Standard features included Bluetooth, Apple CarPlay, Android Auto, and Mercedes me connect services. However, wireless device charging was not available.

The 2020 Cadillac XT6 had not been crash-tested by the NHTSA or IIHS, but it was expected to receive top scores. It offered a range of safety features, including rear pedestrian detection, a digital rear-view mirror, and 360-degree cameras. The Driver Assist Package added forward emergency braking, adaptive cruise control, and seat-belt tightening.

The 2021 Mercedes-Benz G-Class came with a comprehensive suite of safety features, including a rearview camera, Pre-Safe, traffic-sign assist, attention assist, active lane-keeping assist, and more. The G550's size and weight provided safety advantages in some crashes, but also posed risks to pedestrians and cyclists. The G-Class had not been rated by the NHTSA or IIHS.
