2022 Mercedes-Benz GLS vs 2023 Kia Sportage Hybrid

The 2022 Mercedes-Benz GLS 450 presented a more understated appearance compared to its flashier competitors like the Cadillac Escalade and Lincoln Navigator. Mercedes confidently avoided an ostentatious grille, unlike the BMW X7 or Lexus LX. However, other GLS models offered more visual flair, such as the AMG GLS 63 with its aggressive styling and the Maybach version with extensive chrome detailing. The interior of the GLS 450, while 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, enhancing the overall luxury feel.

In contrast, the 2023 Kia Sportage Hybrid embraced a bold design with its angular LED headlights and distinctive "boomerang" LED daytime running lights. The Sportage Hybrid's interior was centered around a large optional infotainment display, offering a minimalist and elegant look. While the base models featured cloth seats, higher trims used SynTex artificial leather, which felt somewhat cheap. The interior also included practical features like a rotary shift knob and clever cupholders, enhancing the overall functionality and appeal of the cabin.

The 2022 Mercedes-Benz GLS 450 was powered by a 3.0-liter turbocharged inline six-cylinder engine paired with a nine-speed automatic transmission, producing 362 horsepower and 369 pound-feet of torque. The EQ Boost mild-hybrid system added 21 hp and 184 lb-ft of torque in short bursts. The GLS 450's engine provided ample power, and the electric assist was well-integrated. However, the air suspension exhibited poor body control, leading to a less comfortable ride. The GLS 450 had a towing capacity of 7,700 pounds, which was competitive but not class-leading.

The 2023 Kia Sportage Hybrid featured a 1.6-liter turbocharged four-cylinder engine and a six-speed automatic transmission, delivering 227 horsepower and 258 pound-feet of torque. The powertrain provided smooth and predictable acceleration, with seamless transitions between electric and gasoline power. The Sportage Hybrid's transmission was well-tuned, offering smooth shifts and quick responses. While not a driver's car, the Sportage Hybrid delivered a comfortable ride and quiet cabin. Its towing capacity was 2,000 pounds, slightly less than the non-hybrid version.

The 2022 Mercedes-Benz GLS offered a seven-seat configuration with a 60/40 split-folding second-row bench seat and two third-row seats. An optional six-seat version featured individual captain’s chairs. The GLS provided excellent second-row legroom, thanks to its long wheelbase. Cargo space was 17.4 cubic feet with all seats in place, expanding to 84.7 cubic feet with the second and third rows folded. The GLS included power-folding seats and a power tailgate for easy loading and unloading.

The 2023 Kia Sportage Hybrid had slightly less headroom and cargo space than the non-hybrid version but remained competitive in its segment. It offered a dual-level cargo floor, providing 39.5 cubic feet of cargo space with the rear seats in place and 73.7 cubic feet with the seats folded. The Sportage Hybrid featured a rotary shift knob, freeing up space between the front seats. It also included practical storage solutions, such as a large bin for phones and clever cupholders.

The 2022 Mercedes-Benz GLS came with the MBUX infotainment system, featuring a 12.3-inch touchscreen, digital instrument cluster, Bluetooth, Apple CarPlay/Android Auto, navigation, and a 13-speaker Burmester audio system. The voice recognition system was user-friendly, responding to the prompt “Hey Mercedes.” However, the touchpad controller was cumbersome, and the navigation system occasionally suggested inefficient routes.

The 2023 Kia Sportage Hybrid offered an 8-inch touchscreen with wireless Apple CarPlay and Android Auto, and a 4G LTE WiFi hotspot. Higher trims featured a panoramic display with a 12.3-inch touchscreen and digital instrument cluster. The panoramic display was visually impressive and user-friendly, although Android Auto didn’t utilize the entire screen. The Sportage Hybrid also included touch controls and analog knobs for audio and climate adjustments, along with multiple USB-C ports and an optional Harman Kardon audio 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. Optional features included adaptive cruise control, lane-keep assist, and advanced driver-assistance systems. Crash-test ratings from the IIHS and NHTSA were unavailable at the time of publication.
