Mercedes-Benz G-Class vs Mercedes-Benz GLA

The 2021 Mercedes-Benz GLA was a modern take on the subcompact SUV, positioned as the entry-level model in the Mercedes SUV lineup. Its design was characterized by short overhangs and cladding, giving it a muscular appearance despite its small size. The GLA was three inches taller and half an inch shorter than its predecessor, offering a more SUV-like seating position with ample visibility. However, the interior left much to be desired, with less-than-premium surfaces and a lack of luxury compared to other crossovers. While the seats were comfortable, the overall interior quality did not match the expectations set by its exterior design.

In contrast, the 2021 Mercedes-Benz G-Class, or G-Wagen, was a testament to rugged luxury. Its boxy, retro exterior was a nod to its military origins, while the interior offered a tasteful design with a 12.3-inch widescreen infotainment system and virtual instrument panel. The G-Class was a status symbol, often seen in bold custom colors and adorned with luxury features. Despite its opulent appeal, it remained a capable off-road machine, blending luxury with functionality in a way that few vehicles could match.

The 2021 Mercedes-Benz GLA offered a range of performance options, starting with the GLA 250 and GLA 250 4MATIC, both powered by a 2.0-liter turbocharged four-cylinder engine producing 221 horsepower and 258 pound-feet of torque. This engine allowed the GLA to accelerate from zero to 60 mph in 6.8 seconds, with a top speed of 130 mph. The AMG GLA 35 variant increased power to 302 hp and 295 lb-ft of torque, achieving a zero to 60 mph time of 5.1 seconds. The AMG GLA 45 further enhanced performance with 382 hp and 354 lb-ft of torque, reaching 60 mph in just 4.3 seconds. Despite these impressive figures, the GLA struggled with turbo lag and road noise, impacting its overall driving experience.

The 2021 Mercedes-Benz G-Class, particularly the G550 model, was a powerhouse with a twin-turbocharged 4.0-liter V8 engine delivering 416 horsepower and 450 pound-feet of torque. This allowed the G550 to sprint from zero to 60 mph in 5.6 seconds, impressive for its 5,551-pound curb weight. The G-Class featured a nine-speed automatic transmission and permanent four-wheel drive, with dynamic driving programs for various terrains. The AMG G63 variant took performance to another level with 577 hp and 627 lb-ft of torque, achieving a zero to 60 mph time of 4.5 seconds. Despite its size, the G-Class offered a surprisingly nimble and capable driving experience, both on and off-road.

The 2021 Mercedes-Benz GLA provided a comfortable interior with excellent headroom and legroom for front passengers. The rear seats, with a 40/20/40 split-fold, offered improved legroom, making them suitable for smaller adults. The GLA's cargo space was average for its class, with 15.4 cubic feet behind the rear seats and 50.5 cubic feet with the seats folded. The low load floor and available power liftgate made loading and unloading cargo convenient.

The 2021 Mercedes-Benz G-Class excelled in interior space and functionality. The G550 offered 38.1 cubic feet of cargo space behind the third row, expanding to 68.6 cubic feet with the second row folded. The front cabin was spacious, with ample storage and a tall roofline providing excellent headroom. The second row accommodated three adults comfortably, with a 60/40 split-folding seatback. While luxury features like heated seats were standard, some options required expensive packages. The G-Class's exterior spare tire was both a styling cue and a practical feature.

The 2021 Mercedes-Benz GLA came equipped with the Mercedes-Benz User Experience (MBUX) infotainment system, featuring two 7.0-inch display screens. The system was user-friendly, with touch and touchpad controls, and included standard features like Bluetooth, Apple CarPlay, and Android Auto. Upgrades included a 10.25-inch touchscreen, Burmester audio, and wireless charging. The MBUX system was intuitive, though it lacked quick scrolling for radio stations. The GLA also introduced a car-wash function for added convenience.

The 2021 Mercedes-Benz G-Class boasted twin 12.3-inch HD screens for the instrument panel and infotainment, offering customizable layouts and colors. The COMAND system, controlled via unique Touch Control buttons on the steering wheel, provided a seamless user experience. The G-Class included standard features like Bluetooth, Apple CarPlay, and Android Auto, with options for rear-seat entertainment and WiFi. However, wireless device charging was notably absent.

The 2021 Mercedes-Benz GLA offered a reasonable array of active safety features, including a rearview camera, blind-spot monitoring, and forward-collision warning. The optional Driver Assistance Package added advanced safety technologies like adaptive cruise control and active lane-keeping assist. However, the GLA's standard safety features were less comprehensive than some competitors, and the Parking Assistance Package required an additional investment.

The 2021 Mercedes-Benz G-Class came with a robust suite of standard safety systems, including Pre-Safe, active brake assist, and adaptive cruise control. The G-Class's size and construction provided inherent safety advantages, though its active lane-keeping assist could be intrusive. Despite its safety features, the G-Class had not been rated by major safety organizations.
