The 2021 Mercedes-benz Glc-class stands as a testament to enduring excellence in the competitive luxury SUV segment. Much like seasoned athletes or accomplished leaders, maintaining a leading position is often more challenging than achieving it initially. The GLC-Class, evolving from its GLK predecessor launched in 2010, not only pioneered the small luxury SUV category but has consistently refined its blend of comfort, performance, practicality, and cutting-edge technology. This ongoing dedication to improvement has solidified its place at the top of small luxury SUV rankings, confidently outperforming a growing list of rivals, including the Audi Q5, BMW X3, and Volvo XC60.
The Cost of Ownership: Fuel Economy of the 2021 GLC-Class
Understanding the running costs is crucial for any vehicle, and the 2021 Mercedes-Benz GLC-Class doesn’t disappoint in terms of fuel efficiency. For the GLC 300 4dr SUV (2.0L 4cyl Turbo 9A) model, estimated monthly fuel costs are around $191, based on 15,000 miles per year with a 55% city and 45% highway driving mix, and assuming a premium unleaded fuel price of $3.85 per gallon. This is a competitive figure when compared to the average midsize SUV, which comes in at approximately $178 per month.
The GLC-Class masterfully combines spaciousness with versatility, making it equally adept at handling daily commutes and weekend family trips. Its comprehensive suite of technology and safety features provides peace of mind in navigating the challenges of modern roads. Furthermore, the GLC lineup caters to a wide range of driving preferences, offering everything from efficient and comfortable models to high-performance AMG variants. Even after more than a decade at the forefront, the 2021 Mercedes-Benz GLC-Class continues to set the standard, urging potential buyers to delve into expert reviews for a thorough evaluation.

Rated by America’s best test team.
Performance: 8.5/10
Driving Dynamics and Powertrain
The GLC 300 model demonstrates robust power suitable for various driving scenarios, from highway merging to quick overtaking on country roads. Edmunds testing recorded a 0-60 mph acceleration time of just 5.8 seconds, notably quicker than the average for a small luxury SUV equipped with a base four-cylinder engine. In comparison, the Audi Q5 achieved this benchmark in 6.2 seconds. The GLC’s nine-speed automatic transmission operates with seamless gear changes and swift responses.
Maneuverability is another key strength, with light and responsive steering ideal for city driving. Selecting Sport or Sport+ mode adds a welcome weight to the steering, enhancing driver engagement without compromising comfort. The well-tuned suspension and confident brakes further contribute to the GLC’s polished road manners, providing a balanced and enjoyable driving experience.
Comfort: 8.5/10
Ride Quality and Cabin Serenity
The 2021 GLC-Class sets a high standard for ride comfort. It effectively absorbs road imperfections, providing a stable and controlled feel, truly representing the pinnacle of refinement in its class. The front seats offer exceptional comfort with extensive adjustability to accommodate various body types. The cabin effectively isolates external noise, and test vehicles exhibited no unwanted creaks or rattles, fostering a tranquil driving environment. The climate control system is responsive and user-friendly, even offering voice control via the MBUX infotainment system, enhancing the overall serene and comfortable atmosphere.
Interior: 8.5/10
Cabin Design and Ergonomics
The GLC’s interior is notably spacious, with controls thoughtfully positioned within easy reach, thanks to the driver’s seat’s wide adjustment range. Entry and exit are convenient, and rear passengers enjoy ample legroom, even behind taller front occupants. While rear doors don’t open as widely as the front ones, accessibility remains excellent. The standard MBUX infotainment system features intuitive menus and controls for almost every vehicle function. Users can interact with the system through touchscreen inputs, a touchpad, steering wheel controls, or voice commands, all of which respond quickly and reliably, enhancing the user-friendly interior design.
Technology: 9/10
Infotainment and Driver Assistance
The 10.25-inch MBUX center screen impresses with its sharp graphics and clear menu layouts. Optional integrated navigation and a digital instrument cluster further enhance the technological appeal. Standard Apple CarPlay and Android Auto provide seamless smartphone integration with rapid boot-up times. The voice control system stands out for its accuracy and range of functions, proving genuinely useful.
The GLC also excels in driver assistance technologies. Adaptive cruise control maintains consistent following distances without abrupt braking, even in heavy traffic. Combined with lane keeping assist, it offers impressive semi-automated driving capabilities in highway congestion. The surround-view camera system is invaluable for parking in tight spots, adding an extra layer of technological convenience and safety.
Storage: 7/10
Cargo and Small Item Stowage
Practicality in terms of storage is not the GLC’s strongest suit. Cargo space behind the rear seats is 19.4 cubic feet, less than the BMW X3’s 28.7 cubic feet. Towing capacity is rated at 3,500 pounds (when properly equipped), also less than the BMW X3’s 4,400 pounds. Small-item storage within the cabin is adequate but not exceptional, with limited dedicated smartphone storage. However, the GLC is family-friendly, easily accommodating two child safety seats in the spacious rear, with readily accessible car seat anchors and tether points.
Fuel Economy: 7.5/10
Real-World MPG
The EPA estimates the rear-wheel-drive GLC 300 at 24 mpg combined. Edmunds’ real-world testing largely corroborated this, recording 25.8 mpg on a 115-mile mixed-driving route. More powerful GLC variants naturally have lower fuel economy, with the GLC 63 estimated at 18 mpg combined. The GLC 300 offers a reasonable balance of performance and fuel efficiency for daily driving.
Value: 8/10
Pricing and Features
The GLC-Class is competitively priced within its segment and exudes luxury commensurate with its cost. High-quality materials are evident throughout the interior, and controls have a substantial, premium feel. Precise German build quality is apparent in tight body panel gaps. The inclusion of the standard MBUX system enhances its value proposition. However, Mercedes’ warranty coverage lags behind competitors. While brands like Jaguar and Infiniti offer more extensive warranties, the GLC falls short compared to Audi and BMW in this area.
Wildcard: 8/10
Everyday Luxury and Enjoyment
Mercedes-Benz prioritized everyday luxuries in the GLC’s design. 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 offers a sense of calm and well-being. While not overtly sporty, the GLC is a vehicle drivers will likely look forward to driving daily, thanks to its overall refinement and enjoyable driving dynamics.
Edmunds Recommendation: Which 2021 GLC-Class Model is Best?

It provides a comprehensive suite of features expected in a luxury SUV, with ample opportunities for customization through technology, comfort, and safety upgrades.
