What’s New for the 2021 Model Year?
For the 2021 model year, Mercedes-Benz has made subtle but significant updates to the GLC range. Notably, the GLC 350e plug-in hybrid version has been discontinued. Feature availability has seen minor revisions, streamlining the options and packages. This model year remains part of the first GLC generation, which was initially introduced in 2016, indicating a mature and well-refined platform.
Driving Experience: Performance and Handling
Performance Rating: 8.5/10
The driving dynamics of the 2021 Mercedes-Benz GLC are truly impressive. We tested the GLC 300 model, equipped with the standard four-cylinder turbocharged engine, and found it delivers ample power for various driving situations, from navigating busy city streets to cruising on motorways. Merging onto a motorway or overtaking on A-roads is effortless, thanks to the responsive engine. In independent testing, the GLC 300 achieved a 0-60 mph time of just 5.8 seconds, which is notably quick for a base-engine luxury SUV. This performance outpaces competitors like the Audi Q5, which recorded a 0-60 mph time of 6.2 seconds.
The nine-speed automatic transmission is a highlight, providing smooth and rapid gear changes, contributing to both performance and fuel efficiency. Manoeuvrability is another key strength, especially in urban environments. The steering is light and responsive, making city driving and parking straightforward. For those seeking a more engaging driving experience, Sport or Sport+ modes add a welcome heft to the steering, without compromising the overall comfort that GLC drivers expect. The well-tuned suspension and strong brakes further enhance the GLC’s composed and confident road manners.
Comfort and Interior Refinement
Comfort Rating: 8.5/10
Comfort is where the 2021 GLC truly excels. The ride quality is outstanding, effectively absorbing bumps and road imperfections, providing a stable and controlled feel, even on less-than-perfect UK roads. This level of refinement is exceptional for an SUV in this segment. The front seats are exceptionally comfortable, offering a wide range of adjustments to cater to drivers of all shapes and sizes. Noise insulation is excellent, keeping wind and road noise to a minimum, creating a serene and relaxing cabin environment. Our test GLC exhibited no creaks or rattles, further emphasizing the high build quality. The climate control system is efficient and user-friendly, quickly achieving and maintaining the desired temperature, with intuitive controls, including voice activation via the MBUX infotainment system.
Interior Design and Space Rating: 8.5/10
The GLC’s interior is not only comfortable but also remarkably spacious. The cabin feels airy and offers ample room for both front and rear passengers. Most vehicle controls are easily accessible from the driver’s seat, thanks to the wide range of seat and steering wheel adjustability. Getting in and out of the GLC is easy, and rear passengers will appreciate the generous legroom, even when seated behind taller occupants. While the rear doors don’t open quite as wide as the front doors, access to the rear seats remains convenient.
Technology and Connectivity
Technology Rating: 9/10
Mercedes-Benz is renowned for its technological innovation, and the 2021 GLC is no exception. The standard 10.25-inch MBUX infotainment screen is a centerpiece, boasting vibrant graphics and intuitive menus. Optional features like integrated navigation and the digital instrument cluster further enhance the tech-forward feel. Apple CarPlay and Android Auto come standard, offering seamless smartphone integration with quick and reliable connectivity.
The voice control system is particularly impressive, accurately understanding and responding to natural language commands, making it genuinely useful for controlling various vehicle functions. The GLC also excels in driver assistance technology. Adaptive cruise control maintains a consistent and safe following distance, even in stop-and-go traffic, and reacts smoothly to vehicles cutting in. Combined with lane keeping assist, it offers a degree of semi-automated driving capability, particularly useful in motorway congestion. The available surround-view camera system is invaluable for parking in tight spots, a common scenario in UK cities.
Practicality: Storage and Fuel Economy
Storage Rating: 7/10
While the GLC excels in many areas, storage is not its strongest suit. Cargo space behind the rear seats is 19.4 cubic feet, less than some competitors like the BMW X3, which offers 28.7 cubic feet. Towing capacity is also somewhat limited at 3,500 pounds when properly equipped, compared to the BMW X3’s 4,400 pounds. Small-item storage within the cabin could also be improved, with limited dedicated space for smartphones and other everyday items. However, for families, the GLC is still practical. The spacious rear seats can comfortably accommodate two child safety seats, and the car seat anchors are easily accessible.
Fuel Economy Rating: 7.5/10
Fuel economy for the base GLC 300 is respectable for a luxury SUV. The EPA estimates 24 mpg combined for the rear-wheel-drive model, and our testing largely corroborated this, with an observed 25.8 mpg on a mixed-driving evaluation route. More powerful AMG models naturally have lower fuel economy figures, with the GLC 63 estimated at 18 mpg combined. For UK drivers conscious of fuel costs, the GLC 300 offers a reasonable balance of performance and efficiency.
Value and Trims: Choosing Your GLC
Value Rating: 8/10
The 2021 Mercedes-Benz GLC is priced competitively within the luxury SUV segment and justifies its price with its high-quality feel and extensive features. The interior materials are premium, and the overall build quality is exceptional, reflecting Mercedes-Benz’s renowned attention to detail. The inclusion of the MBUX infotainment system as standard further enhances its value proposition. However, the warranty coverage is less generous than some competitors, which is a point to consider for UK buyers prioritizing long-term peace of mind.
