The differences between the GLS and GL include exterior and interior variations. Specific details are as follows: Exterior differences: The most significant distinction lies in the front grille, where the oversized three-pointed star emblem and dual horizontal bars provide high recognition. Other changes encompass new front and rear bumpers, headlights, taillights, and wheels. Additionally, elements such as roof racks, underbody guards, window trims, trunk handles, and side sill steps incorporate extensive use of chrome accents. Interior differences: The new instrument cluster features a semi-embedded display, while the three-spoke leather steering wheel is equipped with 12 control buttons. The GLS comes with an 8-inch central control screen and a multi-touch handwriting touchpad.

















The main differences between the GLS and GL lie in generational updates and technological upgrades. Having driven several Mercedes SUVs, I found that the GL was the previous generation of large SUV models, now largely discontinued. While it was spacious enough for family road trips, its design was outdated, and the in-car technology and comfort were mediocre. The GLS is the successor to the GL, representing the new generation. It features a larger and more luxurious body, with the latest MBUX system in the interior, upgraded touchscreens and control panels. Inside, the space feels more expansive, the third-row seating is more practical, and it includes active safety features like blind-spot monitoring. In daily driving, the GLS has better suspension tuning, offering a smoother ride on bumpy roads, and slightly improved fuel efficiency compared to the GL. For used car buyers, the GL is cheaper, but the GLS is the better choice as it meets all modern demands, with significantly improved overall quality and reliability. In the long run, the GLS holds its value better and is less troublesome to maintain.

From my perspective as a family user, the key differences between the GLS and GL lie in daily driving experience. The GL is an earlier-generation full-size SUV with decent space – particularly its spacious trunk that easily accommodates luggage for family camping trips. However, its cabin comfort is mediocre; long drives often result in backaches. The older model also lacks advanced technologies, making parking and cornering more challenging for novice drivers without sufficient assistance features.
The GLS, as a completely redesigned successor, features optimized body architecture and more ergonomic third-row seating, ensuring kids won't complain about cramped space. Its upgraded interior delivers significantly better noise insulation, especially noticeable during highway drives. Standard adaptive cruise control and emergency braking in the GLS provide added reassurance for family trips. Though priced higher, the GLS proves more economical long-term with better fuel efficiency and lower maintenance costs. For family SUV selection, the GLS clearly outperforms with balanced urban commuting and highway capabilities.

The main differences between the GLS and GL lie in design evolution and performance upgrades. As an automotive enthusiast, I follow brand development closely. The GL was the older-generation flagship SUV, featuring a rugged exterior with a utilitarian focus. While it delivered sufficient power, the ride was relatively stiff, and body roll was noticeable during cornering. The GLS is its evolved successor, boasting a more streamlined and sporty appearance, modern LED lighting clusters, and a more imposing grille. The core upgrade lies in its advanced suspension technology, offering sharper handling and smoother acceleration without hesitation. Inside, the GLS adds more interactive features, with digital instrument clusters and ambient lighting enhancing the luxury feel. Historically, Mercedes-Benz replaced the GL with the GLS, reflecting a shift toward high-tech and comfort-oriented trends. In the used car market, the GL is cheaper but condition varies, while the GLS is more sought-after as it embodies the brand's essence.

When discussing the differences between the GLS and GL, the key lies in the upgrade of luxury. I have experienced these vehicles firsthand. The GL is the older SUV model, featuring traditional interior materials that are comfortable but lack refinement. Its audio system and seat configurations are basic, making long highway drives tiring. The GLS, on the other hand, is entirely different. While its body dimensions are slightly larger, its lines are more elegant. The interior, adorned with premium leather and wood, exudes sophistication. Standard features like massage seats and temperature-controlled cup holders create an immediate sense of high-end ambiance. The noise insulation is outstanding, and when paired with the Burmester sound system, the audio quality far surpasses that of the GL. Technologically, the GLS introduces lane-keeping assist and automatic parking, enhancing safety. Cost-wise, the GLS is more expensive, but the driving experience and brand prestige it offers are significantly superior, making it ideal for those who prioritize quality of life. Maintenance for both models is similar, but GLS parts are easier to find, ensuring stable future value.

The differences between the GLS and GL are reflected in practicality and daily cost-effectiveness. Having driven for several years, I can say the GL is the previous generation SUV—spacious but technologically outdated, lacking features like a rearview camera, which makes urban parking challenging. Its interior feels plasticky, and the heating system is slow to warm up in winter. The GLS, as the newer version, retains a similar size but optimizes details, adding more storage compartments and convenient wireless phone charging. Its smart climate control adjusts temperatures faster. The GLS's engine is more efficiently tuned, reducing fuel consumption by 10%, saving money and being eco-friendlier, with more standardized parts for repairs. While used GLs are cheaper, they have higher failure rates, whereas the GLS proves far more reliable. For average drivers, the GLS is the better choice—handling city traffic and highways with ease, requiring less maintenance, and ideal for long-term ownership.
