The GLB is a compact SUV with optional third-row seating, while the GLC is a slightly larger midsize SUV focused on comfort and performance. Understanding the key differences between these two models is crucial for making an informed decision when considering a Mercedes-Benz SUV purchase.
Let’s compare the main features of the Mercedes-Benz GLB and GLC to highlight their differences:

Now, let’s delve deeper into the specific differences between the Mercedes-Benz GLB and GLC to help you determine which model best suits your needs.
Size and Exterior Design
The Mercedes-Benz GLB and GLC differ significantly in their exterior design and overall size. The GLB is designed as a compact SUV with a more boxy and rugged appearance, reminiscent of the iconic G-Class. It measures 4,634 mm in length, 2,020 mm in width, and 1,663 mm in height. The GLB’s squared-off design maximizes interior space and gives it a distinctive look in the Mercedes lineup.
On the other hand, the GLC is classified as a midsize SUV with a more sleek and curved design. It’s slightly larger than the GLB, measuring 4,716 mm in length, 1,890 mm in width, and 1,640 mm in height. The GLC’s design is more in line with Mercedes’ current styling language, featuring a smoother silhouette and more aerodynamic profile.
The exterior differences between these two models reflect their intended purposes:
- GLB: More utilitarian and adventure-oriented
- GLC: Focused on luxury and on-road performance
Both models offer distinctive LED lighting signatures and a range of wheel options, but the GLB tends to have a more upright stance, while the GLC has a more planted and sporty appearance.
Interior Space and Seating
One of the most significant differences between the GLB and GLC lies in their interior configurations. The GLB offers a unique feature in its class: optional third-row seating. This allows the GLB to accommodate up to seven passengers, making it an excellent choice for larger families or those who occasionally need extra seating capacity. However, it’s important to note that the third row is best suited for children or short trips, as space is limited.
The GLC, being a traditional midsize SUV, offers seating for five passengers only. It prioritizes comfort for these five occupants, providing more generous legroom and shoulder room in both the front and rear seats compared to the GLB.
When it comes to cargo space, the GLB surprisingly offers more versatility:
- GLB: Up to 62 cubic feet of cargo space with rear seats folded
- GLC: Up to 56.3 cubic feet of cargo space with rear seats folded
This difference is due to the GLB’s boxier design, which allows for more efficient use of interior space. However, the GLC offers a slightly larger cargo area behind the second row when all seats are in use.
Performance and Powertrain Options
Both the GLB and GLC offer a range of powertrain options, but the GLC generally provides more powerful engines and better performance:
GLB:
- Base engine: 2.0L turbocharged inline-4 producing 221 horsepower and 258 lb-ft of torque
- AMG GLB 35: 2.0L turbocharged inline-4 producing 302 horsepower and 295 lb-ft of torque
GLC:
- Base engine: 2.0L turbocharged inline-4 producing 255 horsepower and 295 lb-ft of torque
- AMG GLC 43: 3.0L turbocharged inline-6 producing 416 horsepower and 369 lb-ft of torque
The GLC’s more powerful base engine results in quicker acceleration times:
- GLB 250: 0-60 mph in 6.9 seconds
- GLC 300: 0-60 mph in 6.2 seconds
Both models come standard with front-wheel drive, with 4MATIC all-wheel drive available as an option. The GLC, however, offers a more sophisticated AWD system and better handling dynamics due to its lower center of gravity and more refined suspension setup.
Technology and Features
While both the GLB and GLC offer advanced technology features, the GLC generally comes with more standard equipment and has access to more high-end options:
GLB standard features:
- 7-inch digital instrument cluster
- 7-inch touchscreen infotainment system
- Apple CarPlay and Android Auto
- Dual-zone automatic climate control
GLC standard features:
- 12.3-inch digital instrument cluster
- 11.9-inch touchscreen infotainment system
- Wireless Apple CarPlay and Android Auto
- Dual-zone automatic climate control
- Heated front seats
Both models offer the latest MBUX (Mercedes-Benz User Experience) infotainment system, but the GLC’s larger screens provide a more premium and immersive experience. The GLC also has access to more advanced driver assistance features and luxury options, such as:
- Augmented reality navigation
- Head-up display
- Air suspension
- 360-degree camera system
Pricing and Value
The Mercedes-Benz GLB starts at a lower price point compared to the GLC, making it a more accessible entry into the luxury SUV market:
- 2025 GLB 250 starting price: $45,800
- 2025 GLC 300 starting price: $50,400
This price difference reflects the GLB’s positioning as a compact SUV and the GLC’s more premium status in the lineup. However, the GLB offers excellent value for those who prioritize versatility and don’t need the extra performance or luxury features of the GLC.
When fully equipped, both models can reach similar price points, but the GLC will generally offer more high-end features and better performance at those higher trim levels.
Fuel Economy
The GLB’s smaller size and less powerful base engine contribute to slightly better fuel economy compared to the GLC:
GLB 250:
- City: 25 mpg
- Highway: 33 mpg
- Combined: 28 mpg
GLC 300:
- City: 23 mpg
- Highway: 31 mpg
- Combined: 26 mpg
While the difference is not substantial, it can add up over time, especially for those who do a lot of city driving. Both models offer similar fuel tank capacities, with the GLB holding 15.9 gallons and the GLC holding 17.4 gallons.
