2021 Mercedes-Benz GLS vs 2022 Kia EV6

The 2021 Mercedes-Benz GLS, a continuation of the third generation introduced in 2020, was a luxurious SUV that combined practicality with opulence. Originally intended to replace the G-Class, the GLS evolved from the GL-Class, appealing to affluent families with its three rows of seating and a comfortable interior. The GLS's design was more refined than its predecessors, featuring softened angles and a sleek appearance. Inside, the cabin was futuristic, dominated by a massive digital screen that emphasized the vehicle's tech-centric controls. The GLS was available in three trims: GLS 450, GLS 580, and the high-performance AMG GLS 63, each offering a range of standard and optional features that enhanced comfort and convenience.

In contrast, the 2022 Kia EV6 was a sporty and stylish electric vehicle that stood out with its sleek design and innovative features. The EV6's exterior was characterized by its low and wide stance, with a highback tail and a lip spoiler that doubled as a lightbar. The vehicle's design included voluptuous curves reminiscent of a Porsche 911, and its headlights traced a V-shaped pattern. The interior was equally impressive, featuring dual 12-inch screens, a floating center console, and seats covered in faux suede and leather. The EV6's design was both functional and aesthetically pleasing, with features like retractable door handles and a hidden rear charge port adding to its allure.

The 2021 Mercedes-Benz GLS offered a range of powerful engine options. The entry-level GLS 450 was equipped with a twin-turbocharged 3.0-liter inline-six engine, producing 362 horsepower and 369 pound-feet of torque. The GLS 580 featured a more robust twin-turbocharged 4.0-liter V8 engine, delivering 483 hp and 516 lb-ft. The AMG GLS 63, the most powerful variant, boasted a hand-crafted 4.0-liter twin-turbo V8 engine, generating an impressive 603 hp and 627 lb-ft of torque. All models came with a nine-speed automatic transmission and Mercedes' 4MATIC all-wheel-drive system. The AMG GLS 63 could accelerate from zero to 60 mph in just 4.1 seconds, with a top speed of 174 mph. The GLS also featured an adaptive air suspension system, multiple drive modes, and E-Active Body Control for a smooth and composed ride.

The 2022 Kia EV6, on the other hand, was an electric powerhouse. The GT-Line e-AWD model we tested had two electric motors producing 320 horsepower and 446 pound-feet of torque, allowing it to reach 60 mph in a claimed 4.6 seconds. The EV6's performance was further enhanced by its 77-kilowatt-hour battery, which provided a low center of gravity and excellent handling. The upcoming GT trim promised even more power, with 576 hp and a 0-60 time of less than 3.5 seconds. The EV6 offered a range of regenerative braking settings and drive modes, allowing for a customizable driving experience. However, its driving range was affected by cold weather, and charging times varied depending on the station's output.

The 2021 Mercedes-Benz GLS provided ample interior space with three rows of seating, accommodating up to seven passengers. The first and second rows offered generous headroom and legroom, while the third row was suitable for adults. The GLS boasted 17.4 cubic feet of cargo space behind the third row, expanding to 42.7 cubic feet with the third row folded, and 87.4 cubic feet with both the second and third rows down. The vehicle featured numerous storage compartments, including spacious in-door bins and a center console with butterfly doors.

The 2022 Kia EV6 offered a spacious interior with a low floor, providing generous legroom and headroom for all passengers. The rear seats reclined and had air vents, creating an open and airy atmosphere. However, the cargo space was limited, with only 24 cubic feet behind the seats and 50 cubic feet when folded. The EV6's towing capacity was 2,300 pounds, and it featured an onboard power generator for added versatility.

The 2021 Mercedes-Benz GLS was equipped with the MBUX infotainment system, featuring a massive touch screen and a trackpad for easy navigation. The system included Apple CarPlay and Android Auto, though a USB-C cable was required for connectivity. The MBUX system also offered voice control, allowing users to issue complex commands. The digital dash extended to the instrument panel, both controlled by touch-sensitive pads on the steering wheel, providing a customizable and tech-savvy experience.

The 2022 Kia EV6's infotainment system was user-friendly, with dual 12-inch screens and a range of connectivity options. However, wireless Apple CarPlay and Android Auto required a wired connection. The EV6 featured a 360-degree camera system, customizable "engine" sounds, and an augmented reality head-up display. The vehicle's tech package included Highway Driving Assist, blind-spot monitoring, and a remote parking system. However, Kia Connect features were disabled for Massachusetts residents due to compliance issues.

The 2021 Mercedes-Benz GLS came standard with a comprehensive suite of driver-assistance features, including Active Brake Assist, forward-collision avoidance, blind-spot monitoring, and automatic high beams. Additional safety tech included lane-keep assist, adaptive cruise control, and a following-distance indicator. The GLS was equipped with a full array of airbags, traction control, and a tire-pressure monitoring system.

The 2022 Kia EV6, while lacking published test results, offered an impressive array of safety features. Standard equipment included lane-keeping, cyclist and pedestrian detection, cross-traffic alert, and a driver attention monitor. Higher trims added features like automatic rear braking, 360 cameras, and evasive steering assist. The EV6's safety package was comprehensive, though some features were disabled in Massachusetts.
