2021 BMW X7 vs 2022 Mercedes-Benz GLS

The 2021 BMW X7 was a standout in the luxury SUV segment, often seen navigating the bustling streets of Los Angeles. It was known for its superior interior quality, surpassing that of the Cadillac Escalade, and boasted more prestige than the Infiniti QX80 or Lincoln Navigator. The X7 also offered advanced technological features that outshone the Lexus LX 570, and its visual presence was more commanding than the Mercedes-Benz GLS-Class. Despite its impressive attributes, the X7's appeal was subjective, as personal preference played a significant role in this segment.

The 2022 Mercedes-Benz GLS, in its base GLS 450 form, presented a more understated appearance compared to its flashier competitors like the Cadillac Escalade and Lincoln Navigator. Mercedes opted for a more refined grille design, avoiding the bold styles seen on the BMW X7 and Lexus LX. The GLS lineup included models like the AMG GLS 63 and Maybach, which offered more dramatic styling and luxurious features. The interior of the GLS 450 was luxurious, with leather upholstery, a panoramic roof, and ambient lighting, though it lacked some of the opulence found in higher trims. The digital instrument cluster and infotainment touchscreen were well-integrated, providing a modern and sophisticated cabin experience.

The 2021 BMW X7 xDrive40i was powered by a turbocharged 3.0-liter inline six-cylinder engine, delivering 335 horsepower and 331 lb-ft of torque. This engine was paired with an eight-speed sport automatic transmission and BMW's xDrive AWD system. The X7 featured BMW's eBoost mild-hybrid technology, which included a 48-volt starter/generator and battery, enhancing fuel efficiency and responsiveness. Despite the technology, the X7's fuel economy ratings were slightly lower than the previous year, with 19 mpg city, 24 mpg highway, and 21 mpg combined. The X7 accelerated from 0 to 60 mph in 5.8 seconds, offering ample power for its size. The Dynamic Handling Package improved maneuverability and stability, though the SUV's weight and body motions were noticeable during spirited driving.

The 2022 Mercedes-Benz GLS 450 was equipped with a 3.0-liter turbocharged inline six-cylinder engine, producing 362 horsepower and 369 lb-ft of torque. The engine was complemented by Mercedes' EQ Boost mild-hybrid system, which added 21 hp and 184 lb-ft of torque in short bursts. The GLS 450's engine was smooth and powerful, providing sufficient performance for a luxury SUV. However, the air suspension exhibited poor body control, leading to excessive motion over bumps and in corners. The GLS 450 had a towing capacity of 7,700 pounds, slightly less than some competitors. Overall, the GLS 450 offered a balanced performance, though it lacked the refinement expected from a luxury vehicle.

The 2021 BMW X7 offered a luxurious interior with features like heated and ventilated front seats, premium Merino leather upholstery, and a five-zone climate control system. The front seats provided exceptional comfort, while the second-row captain's chairs were also comfortable, though access could be challenging due to long rear doors. The third-row seats were surprisingly accommodating for adults, with power adjustments for easy access. The X7's cargo space was limited with all seats in place, offering 48.6 cubic feet with the third row folded and 90.4 cubic feet with the second row down, falling short of class leaders.

The 2022 Mercedes-Benz GLS came standard with a seven-seat configuration, with an optional six-seat version featuring captain's chairs. The second-row seats could slide and fold for third-row access, offering excellent legroom. The GLS provided 17.4 cubic feet of cargo space with all seats up, expanding to 84.7 cubic feet with the second and third rows folded. The cargo area was slightly smaller than competitors like the Cadillac Escalade and Lincoln Navigator. The GLS featured power-folding seats and a power tailgate for convenience, though some ergonomic issues were noted, such as the touchscreen's reach and sun visor size.

The 2021 BMW X7 featured the Live Cockpit Professional digital instrumentation and iDrive 7.0 infotainment system, both with 12.3-inch displays. The system included Android Auto, Apple CarPlay, SiriusXM 360L, and Connected Package Pro with real-time traffic and parking information. The X7 also offered wireless smartphone charging, natural voice recognition, and gesture control, though the latter was inconsistent. The iDrive system was user-friendly, though it could be distracting while driving. A head-up display was available, though visibility was limited with polarized sunglasses.

The 2022 Mercedes-Benz GLS was equipped with the MBUX infotainment system, featuring a 12.3-inch touchscreen and digital instrument cluster. Standard features included Bluetooth, Apple CarPlay/Android Auto, navigation, and a 13-speaker Burmester audio system. The voice recognition system was effective, responding to "Hey Mercedes" prompts, while the touchpad controller was less user-friendly. The GLS lacked the augmented-reality navigation feature found in the S-Class, and the navigation system occasionally suggested inefficient routes. Despite these issues, the GLS offered a comprehensive infotainment experience.

The 2021 BMW X7 came standard with a suite of safety technologies, with additional features available in the Driving Assistance Professional Package and Parking Assistance Package. The Driving Assistance Professional Package included Active Driving Assistant Pro, which offered features like evasive-steering assist, traffic-jam assist, and lane-control assist. The system was generally effective, though it occasionally struggled with lane maintenance and automated lane changes. The Parking Assistance Package added semi-automated parking assist, a surround-view camera, and a drive recorder system.

The 2022 Mercedes-Benz GLS included standard safety features like forward collision warning, automatic emergency braking, blind-spot monitoring, and a surround-view camera system. The Pre Safe system prepared the vehicle for a collision by tightening seat belts and closing windows.
