2022 Mercedes-Benz GLS vs 2023 Lexus GX

The 2022 Mercedes-Benz GLS presented a more understated and refined appearance compared to its flashier competitors like the Cadillac Escalade and Lincoln Navigator. Mercedes opted for a subtle design, avoiding the ostentatious grilles seen on models like the BMW X7 or Lexus LX. However, for those seeking a bit more flair, the AMG GLS 63 performance model offered enhanced visual elements such as flared wheel arches, a muscular grille, and prominent exhaust tips. The Maybach version took luxury to another level with chrome accents, a traditional hood ornament, and power running boards. Inside, the GLS 450's interior, though basic by GLS standards, still exuded luxury with leather upholstery, a panoramic roof, and ambient lighting. The digital instrument cluster and infotainment touchscreen were seamlessly integrated, providing a high-quality feel without being overly fragile.

In contrast, the 2023 Lexus GX boasted a commanding presence with its large spindle grille and significant ground clearance. The GX Black Line Special Edition returned with limited availability and exclusive paint options. Despite its imposing front, the GX's dimensions seemed to shrink along the sides, emphasizing its off-road capabilities. The interior, however, was a mix of luxury and practicality. While it featured heated and cooled front seats and impressive leather upholstery, the use of plastic materials was noticeable. The GX's design, unchanged for 14 years, focused on easy manufacturing and maintaining a luxury price point. Despite this, the GX offered a comfortable driving experience with a power-retracting steering wheel and a spacious centre console.

The 2022 Mercedes-Benz GLS 450 was powered by a 3.0-litre turbocharged inline six-cylinder engine paired with a nine-speed automatic transmission, supported by the Mercedes EQ Boost mild-hybrid system. This setup delivered 362 horsepower and 369 pound-feet of torque, with an additional 21 hp and 184 lb-ft of torque available from the electric motor. The GLS 450's engine provided ample power, and the electric assist was well-integrated. However, the suspension left room for improvement, as it exhibited excessive body motion over bumps and in corners. The GLS 450 had a towing capacity of 3,500 kilograms, which was competitive but not class-leading.

The 2023 Lexus GX featured a naturally aspirated 4.6-litre V8 engine producing 301 horsepower and 329 lb-ft of torque, mated to a 6-speed automatic transmission. While the V8 offered a satisfying sound and linear power delivery, it lagged behind more modern engines in terms of output and fuel efficiency. The GX's towing capacity was 2,948 kilograms, which was respectable but fell short of some competitors. The GX's weight contributed to its predictable handling, and its brakes were strong and reliable. The Torsen torque-sensing limited-slip differential and standard 4WD system enhanced its off-road capabilities.

The 2022 Mercedes-Benz GLS offered a spacious interior with a standard seven-seat configuration, featuring a 60/40 split-folding second-row bench seat and two third-row seats. An optional six-seat version replaced the bench with captain's chairs. The second-row seats could slide forward for third-row access, and the GLS boasted excellent legroom, thanks to its long wheelbase. Cargo space was generous, with 355 litres available with all seats in place and up to 2,400 litres with the second and third rows folded. The GLS's air suspension and power-folding seats made loading and unloading cargo convenient.

The 2023 Lexus GX provided ample cubby space for small items, with a deep centre console bin and convenient cupholders. The GX retained physical controls, which were appreciated by those who preferred hard buttons over touchscreens. The second row offered comfortable seating, while the third row was tight and best suited for occasional use. The GX's cargo space was limited, with 328 litres behind the rear seats and up to 1,832 litres with both the second and third rows folded. The side-hinged trunk door required effort to open and limited access to the cargo area.

The 2022 Mercedes-Benz GLS featured the MBUX infotainment system with a 12.3-inch touchscreen, digital instrument cluster, Bluetooth, Apple CarPlay/Android Auto, and navigation. The system offered multiple control options, including voice recognition, a touchpad controller, and steering wheel touchpads. The voice recognition system was particularly effective, allowing for hands-free operation. The GLS also included augmented-reality navigation, although the embedded navigation system occasionally suggested inefficient routes.

The 2023 Lexus GX's infotainment system, updated in 2022, already felt dated compared to other Lexus models. The 10.3-inch touchscreen was an improvement, offering SiriusXM, Bluetooth, and smartphone compatibility. The Lexus Remote Touch Interface was present but unnecessary due to the touchscreen. The GX included a 17-speaker Mark Levinson audio system and a CD player. While the GX's infotainment lagged behind competitors, its off-road capabilities were impressive, with features like a real 4WD system, downhill assist, and the Kinetic Dynamic Suspension System.

The 2022 Mercedes-Benz GLS came equipped with a comprehensive suite of safety features, including forward collision warning, automatic emergency braking, blind-spot monitoring, lane-keep assist, and Pre Safe, which prepared the vehicle for a potential collision. Optional features included a surround-view camera system, adaptive cruise control, and advanced driver-assistance features. Crash-test ratings from the IIHS and NHTSA were not available at the time of publication.

The 2023 Lexus GX, despite its older design, included the Lexus Safety System+ with features like automatic emergency braking, lane-departure alert, adaptive cruise control, and blind spot monitoring. While it lacked some advanced features, the GX's safety systems were commendable. Crash-test ratings from the NHTSA and IIHS were not available, but the GX's safety features were significantly updated compared to its original 2010 design.
