The GL series consists of SUV models, including: GLA, GLB, GLC, GLE, and GLS. The GLC is a mid-size SUV and the successor to the GLK, which has been locally produced in China. The dimensions of the domestic version of the GLC are 4764 mm in length, 1898 mm in width, and 1642 mm in height, with a wheelbase of 2973 mm. The domestic Mercedes-Benz GLC is equipped with two engines: a low-power 2.0-liter turbocharged engine and a high-power 2.0-liter turbocharged engine. The low-power 2.0-liter turbocharged engine delivers 197 horsepower and a maximum torque of 320 Nm, with a maximum power output at 6100 rpm and a maximum torque range between 1650 to 4000 rpm. The high-power 2.0-liter turbocharged engine produces 258 horsepower and a maximum torque of 370 Nm, with a maximum power output at 6100 rpm and a maximum torque range between 1800 to 4000 rpm.

















The GL series initially started as the GL-Class models, such as the classic GL320 and GL450, before being renamed to GLS. The current mainstream GLS450 features a 3.0-liter six-cylinder engine, offering smooth performance and fuel efficiency, making it ideal for daily driving. The upgraded version, the GLS580, boasts a more powerful V8 engine for those seeking luxury. High-end options include the GLS Maybach for ultimate comfort and AMG variants like the GLS 63 AMG for high-performance SUV enthusiasts. Having driven the GLS450, I can attest to its excellent experience, with a spacious interior that can easily accommodate luggage, making family trips very convenient. Interestingly, older models hold decent value in the used car market—for example, a 2015 GL550 is now much more affordable, and maintenance costs are reasonable. Overall, the Mercedes-Benz GL series offers a wide range of models from practical to luxurious, and choosing the right version can save both hassle and money.

As a long-time car enthusiast, I have a deep understanding of the GL series. It debuted in 2006 as the GL-Class, initially launching the GL450, a four-wheel-drive SUV. Subsequently, the model range expanded to include the economical and practical GL320 CDI diesel variant and the powerful GL550 gasoline version. In 2013, it was updated to the GLS-Class, introducing the GLS400 with a six-cylinder turbocharged engine, followed by the GLS550 upgraded to a V8 engine. Current GLS models include the fuel-efficient GLS350 d diesel option, the standard entry-level GLS450, the luxurious high-performance GLS580, as well as the GLS Maybach and AMG versions like the astonishingly powerful GLS 63 AMG. The model naming typically correlates with engine configurations, where numbers indicate displacement, and the AMG suffix denotes performance enhancements. These evolutions reflect the trend of SUVs transitioning from utilitarian tools to luxurious and versatile vehicles.

For family use, the GL series, now called GLS, is a great fit. Models like the GLS450 offer a seven-seat design, providing comfort and safety for kids in the back row. The GLS350 d diesel version has low fuel consumption, making it ideal for long trips. The premium GLS580 offers more space but comes at a higher price. I think these SUVs are spacious enough to accommodate strollers or pets, and come standard with airbags and active brake systems, ensuring peace of mind when driving in the suburbs. The AMG version is cool but expensive; for regular family use, the GLS450 is reliable and durable enough.

From a technical perspective, the GL series features diverse engine options: the GLS450 utilizes a 3.0-liter six-cylinder turbocharged engine producing 367 horsepower; the GLS580 upgrades to a 4.0-liter V8 biturbo outputting 483 horsepower; while the top-tier GLS63 AMG delivers robust acceleration with up to 603 horsepower. Diesel options like the GLS350 d offer economical and eco-friendly performance. The entire lineup is equipped with a 9-speed automatic transmission paired with the 4MATIC all-wheel-drive system, complemented by an electronic suspension adaptable for both highway and off-road conditions. Technological features include intelligent headlights, MBUX touchscreen controls, and comprehensive driver-assistance functions such as adaptive cruise control.

When on a budget, consider different models in the GL series: a used older GL320 CDI diesel can be acquired for just tens of thousands with high cost-performance; the new GLS450 starts around $100k. High-end models like the GLS580 or exceed $150k and are too luxurious—better opt for the AMG version for enjoyment. It's advisable to compare new and old models; pre-2018 GL-Class models like the GL450 offer affordable used prices and simple maintenance, though higher fuel consumption needs consideration. Overall, the range covers from economical to luxury—choose according to needs.
