Performance of the 2021 GLC 300
8.5/10
How does the 2021 GLC 300 drive? In Edmunds testing, the GLC 300 demonstrated ample power for various driving scenarios. Merging onto highways and executing quick passes are effortless, with a 0 to 60 mph acceleration time of just 5.8 seconds. This is notably quicker than the average small luxury SUV with a base four-cylinder engine, such as the Audi Q5 which achieved 0-60 mph in 6.2 seconds. The GLC 300’s nine-speed automatic transmission delivers smooth and rapid shifts, enhancing the overall driving experience. Maneuverability is another key strength; the steering is light and responsive, ideal for navigating city streets. Switching to Sport or Sport+ mode adds a bit more heft to the steering, maintaining comfort while providing a more engaging feel. The well-tuned suspension and robust brakes further contribute to the GLC 300’s composed and confident road manners.
Comfort in the 2021 GLC 300
8.5/10
Ride comfort is a standout feature of the 2021 GLC 300. It effectively absorbs road imperfections, providing a stable and controlled ride. This level of refinement is exceptional for an SUV of this size. The front seats are exceptionally comfortable, offering a wide range of adjustments to accommodate various body types. The cabin is remarkably quiet, with minimal intrusion from outside noise and no noticeable creaks or rattles, contributing to a serene driving environment. The climate control system is quick to respond and easy to operate, further enhancing passenger comfort. Voice control via the MBUX infotainment system allows for convenient climate adjustments without taking your hands off the wheel.
Interior Design and Space of the 2021 GLC 300
8.5/10
The 2021 GLC 300 boasts a spacious and well-designed interior. The driver’s seat offers extensive adjustability, placing most controls within easy reach. Entry and exit are convenient, and rear passengers enjoy ample legroom, even behind taller front occupants. While the rear doors don’t open quite as wide as the front doors, access remains comfortable. The standard MBUX infotainment system is user-friendly, featuring intuitive menus and controls for nearly every vehicle function. Drivers can interact with the system via touchscreen, touchpad, steering wheel controls, or voice activation, all of which are highly responsive.
Technology Features of the 2021 GLC 300
9/10
The technology within the 2021 GLC 300 is truly impressive. The 10.25-inch MBUX center screen showcases vibrant graphics and clear menus. Optional integrated navigation and the digital instrument cluster enhance the technological appeal. Standard Apple CarPlay and Android Auto provide seamless smartphone integration with quick boot-up times. The voice control system stands out for its accuracy and range, making it genuinely useful. The GLC 300 also excels in driver assistance features. Adaptive cruise control maintains a safe and consistent following distance, even in heavy traffic, and avoids abrupt braking when vehicles merge into your lane. Combined with the lane keeping system, it delivers impressive semi-automated driving capabilities in highway congestion. The surround-view camera system is invaluable for parking in tight spaces.
Storage and Practicality of the 2021 GLC 300
7/10
Storage capacity is not the strongest aspect of the 2021 GLC 300 compared to some competitors. It offers 19.4 cubic feet of cargo space behind the rear seats, less than the BMW X3’s 28.7 cubic feet. Similarly, its maximum towing capacity of 3,500 pounds (when properly equipped) is lower than the BMW’s 4,400 pounds. Small-item storage within the cabin is also somewhat limited, lacking a dedicated smartphone storage space. However, the GLC 300 remains practical for family use, comfortably accommodating two child safety seats in the roomy back seat. The car seat anchors and tether points are easily accessible.
Fuel Economy of the 2021 GLC 300
7.5/10
The EPA estimates the rear-wheel-drive 2021 GLC 300 (the tested model) achieves 24 mpg in combined city/highway driving. Edmunds’ testing largely corroborated this figure, observing 25.8 mpg on their 115-mile mixed-driving evaluation route. More powerful GLC models have lower fuel economy ratings, with the GLC 63 estimated at 18 mpg combined. The GLC 300 strikes a good balance between performance and fuel efficiency for its class.
Value Proposition of the 2021 GLC 300
8/10
The 2021 GLC 300 is priced competitively within the luxury SUV segment and delivers a genuine luxury experience. The interior features premium materials, and the controls have a substantial, high-quality feel. The precise build quality and standard MBUX system contribute to a sense of reasonable value for the price. However, Mercedes’ warranty coverage lags behind some competitors. While brands like Jaguar and Infiniti offer better warranties to compensate for less brand prestige, Mercedes could improve its warranty to match Audi and BMW’s efforts in customer care.
The “Wildcard” Factor of the 2021 GLC 300
8/10
Mercedes-Benz has prioritized everyday luxuries in the 2021 GLC 300. The exceptional interior design and ride comfort are immediately noticeable and appreciated. These strengths make it easier to overlook minor shortcomings like limited cargo space. Stepping into the GLC 300 provides a sense of tranquility and refinement. While “fun to drive” might be subjective, the GLC 300 offers a driving experience that many owners will genuinely look forward to daily.
