The Mercedes-Benz GLC-Class has long been a benchmark in the compact luxury SUV segment. Since its inception as the GLK, Mercedes-Benz has consistently refined the formula of comfort, performance, and technology, keeping the GLC at the top of its class. For the 2021 model year, the GLC-Class continues to impress, holding its own against a growing number of competitors. Let’s delve into what makes the 2021 GLC-Class a compelling choice for discerning drivers.
Cost-Effective Luxury: Fuel Economy of the 2021 GLC 300
For those mindful of running costs, the 2021 Mercedes-Benz GLC 300 offers a surprisingly economical option within the luxury SUV category. Based on North Dakota energy estimates of $3.85 per gallon for premium unleaded, the monthly fuel cost for the GLC 300 is estimated at $191.
| Model | Monthly Fuel Cost (Estimate) |
|---|---|
| GLC-Class GLC 300 | $191 |
| Avg. Midsize SUV | $178 |
Despite being a luxury vehicle, the GLC 300’s fuel consumption is comparable to the average midsize SUV, making it a practical choice for daily commutes and longer journeys alike. Its blend of luxury and relative efficiency sets it apart in the competitive SUV market.

Performance: 8.5/10
8.5/10
The GLC 300’s 2.0-litre turbocharged four-cylinder engine delivers ample power for everyday driving needs. Merging onto motorways and overtaking on B-roads is effortless. Edmunds testing recorded a 0-60 mph time of just 5.8 seconds, quicker than the average for a base-engine small luxury SUV and notably faster than the Audi Q5’s 6.2 seconds. The nine-speed automatic transmission is praised for its smooth and rapid shifts. Manoeuvrability is another key strength, with light and responsive steering ideal for urban environments. Sport and Sport+ modes add weight to the steering for a more engaging driving experience without sacrificing comfort. The well-tuned suspension and strong brakes further enhance the GLC’s composed road manners.
Comfort: 8.5/10
8.5/10
Ride comfort is a standout feature of the GLC-Class. It effectively absorbs bumps and road imperfections, providing a stable and controlled feel. This level of refinement is exceptional for an SUV of this size. The front seats are exceptionally comfortable with a wide range of adjustments. The cabin is remarkably quiet, with minimal road and wind noise intrusion, contributing to a serene driving environment. The climate control system is quick to respond and easy to operate, even via voice control through the MBUX infotainment system.
Interior: 8.5/10
8.5/10
The GLC’s interior is spacious and well-designed. The driver’s seat offers extensive adjustability, placing most controls within easy reach. Getting in and out is convenient, and rear passengers benefit from generous legroom, even behind taller 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, with intuitive menus and multiple control options: touchscreen, touchpad, steering wheel controls, and voice activation – all responsive and quick.
Technology: 9/10
9/10
The 10.25-inch MBUX centre screen boasts vibrant graphics and clear menus. Optional integrated navigation and the digital instrument cluster enhance the tech experience. Standard Apple CarPlay and Android Auto provide seamless smartphone integration with fast boot-up times. The voice control system is particularly impressive, offering accurate and reliable operation. The GLC excels in driver assistance technology, featuring adaptive cruise control that maintains a safe following distance without abrupt braking and a lane-keeping system for semi-automated driving in heavy traffic. The surround-view cameras are invaluable for parking in tight spots.
Storage: 7/10
7/10
Practicality is where the GLC-Class shows some limitations compared to rivals. Cargo space behind the rear seats is 19.4 cubic feet, less than the BMW X3’s 28.7 cubic feet. Towing capacity, at 3,500 pounds (when properly equipped), also trails the BMW X3’s 4,400 pounds. Small-item storage within the cabin is adequate but not exceptional. However, the GLC remains family-friendly, comfortably accommodating two child safety seats in the roomy rear seats, with easily accessible anchor and tether points.
Fuel Economy: 7.5/10
7.5/10
The rear-wheel-drive GLC 300 achieves an EPA-estimated combined fuel economy of 24 mpg. Edmunds’ real-world testing closely mirrored this, recording 25.8 mpg on a 115-mile mixed driving route. More powerful AMG GLC models naturally have lower fuel economy figures, reaching down to 18 mpg for the GLC 63. For a luxury SUV, the GLC 300 offers a reasonable balance of performance and fuel efficiency.
Value: 8/10
8/10
The GLC-Class is competitively priced within its segment and delivers a genuine luxury experience. High-quality materials, substantial controls, and precise build quality justify the price point. The inclusion of the standard MBUX system further enhances its value proposition. However, Mercedes-Benz’s warranty coverage lags behind some competitors. While brands like Jaguar and Infiniti offer more extensive warranties, the GLC’s overall quality and features make it a strong value, even if the warranty isn’t class-leading.
Wildcard: 8/10
8/10
Mercedes-Benz has prioritised everyday luxury in the GLC-Class. The exceptional interior design and ride comfort are immediately noticeable and appreciated. These strengths outweigh minor drawbacks like limited cargo space. Stepping into the GLC provides a sense of calm and relaxation. While not overtly sporty, the GLC is a vehicle you’ll likely enjoy driving daily, offering a refined and pleasurable experience.
