It's undeniable that the SUV has become the single most popular vehicle among drivers today. As such, many brands are keen to offer the very best to the public when designing vehicles. Potential drivers with a knack for the finer things in life might be keen to take an interest in two offerings from one of the finest manufacturers, Mercedes-Benz. When the best in German engineering and sophisticated refinement are applied to the SUV, you're given a posh and practical vehicle.

At Mercedes-Benz of Medford, we're pleased to offer some important information on the 2025 GLA and GLB. As the primary Mercedes-Benz dealer near Cottage Grove, we take immense pride in our selection. Depending on what you're looking for in an SUV, either one of these vehicles has a lot to offer. Today, we're going over the details of both vehicles in the hope of assisting you in choosing what works best for you.

Pricing and Performance

Despite being built by a brand renowned for focusing on luxury, both the GLA and GLB are remarkably affordable compared to some of the other SUVs in the Mercedes-Benz lineup. The 2025 GLA has a starting MSRP of $43,000, whereas the GLB sells for $45,800.[a][b] The GLA is more affordable than the GLB, as would be expected, given that it is the slightly smaller option between the two models.

However, both the GLA and GLB offer the same level of performance, which provides nimble handling and conservative fuel economy. Both SUVs are equipped with a turbocharged 2.0L four-cylinder engine that offers 221 hp and possesses the ability to generate 258 lb-ft of torque. Mercedes-Benz pairs its turbocharged engine with a 48V mild hybrid setup and an eight-speed dual-clutch automatic transmission.

Cottage Grove drivers who have a keen eye for fuel economy will be pleased with what we have to report. The EPA-estimated rankings for fuel economy were fairly generous for both vehicles. The 2025 GLA and 2025 GLB both achieved an estimated 25 MPG in the city and 28 MPG combined. The only differences in the EPA-tested fuel economy were in highway driving and range. The GLA achieved 34 MPG on the highway and a range of 356 miles.[c] In contrast, the GLB achieved 33 MPG on the highway, although its larger fuel tank means that it has a more favorable estimated range of 445 miles.[d]

The GLA is certainly advantageous for Cottage Grove drivers who want to save on up-front costs and enjoy affordable luxury. The GLB offers a longer range between fill-ups and is still an affordable piece of German engineering.

Interior and Cargo Room

Cottage Grove residents who wish to own a versatile, stylish, and spacious vehicle will want to pay close attention to what we report on in this area. Choosing between the GLA and GLB all comes down to what you're looking for in spaciousness, as there's a noticeable difference between both vehicles. With its smaller size, the GLA makes for a more nimble and agile vehicle. However, that doesn't mean that it is cramped inside. The GLA offers seating for up to five passengers and 50.5 cu.ft. of available storage space with the rear seats folded.

For Cottage Grove drivers who are looking for more seating and storage, the GLB offers more advantages. An optional third row of seating can accommodate up to seven passengers. Drivers who choose to remain with seating for five have an added abundance of storage room at their disposal, with 62 cu.ft. available with the second row folded down.

Choosing between the GLA and GLB might come down to a matter of handling versus storage. With its smaller size, the GLA is certainly more appealing to daily commuters. Family-oriented drivers in Cottage Grove will certainly enjoy the GLB and its stronger emphasis on seating and cargo room.

Infotainment and Technology

For the modern driver, having access to the latest technology is not just desirable; it's essential. Mercedes-Benz has always been on the cutting edge of development, whether it's technology or award-winning performance, and the GLA and GLB are both packed with items that make time behind the wheel enjoyable.

An infotainment screen provides many of the items drivers need to access while behind the wheel. The GLA and GLB both include two screens measuring 10.25 inches. One of these is a touchscreen that acts as the gateway to features that include compatibility with Apple and Android products, while the other serves as a driver information center. Additional items, such as a premium sound system, navigation, and access to SiriusXM, are available. Both vehicles offer multiple USB-C ports spread across the first and second rows, allowing you to keep your modern devices hooked up and ready to access at your leisure.

Cottage Grove residents who are looking for a high-tech luxury vehicle will be satisfied with either the GLA or GLB. The gap in pricing between these SUVs is minimal, but the quality of the technology Mercedes-Benz provides access to is not. Ultimately, tech features are unlikely to be a deciding factor in choosing between these two models.

Safety and Driving Assistance Features

Besides the incredible performance and technology that both the GLA and GLB have to offer Cotton Grove area residents, there's also a fair amount of standard and available safety and driving assistance features for oversight and peace of mind. The GLA and GLB come standard with features like Active Brake Assist and Adaptive Highbeam Assist. They even include standard PARKTRONIC with Active Parking Assist, which will parallel or perpendicular park your SUV for you.

Even more features that many drivers look for are available as additional options. Upgrading will grant you access to DISTRONIC® adaptive cruise control with lane-centering technology as well as Active LED headlamps with Active Curve Illumination. An advanced Surround View System is also an optional feature, giving you a complete view of your surroundings with guidelines showing your vehicle's direction of travel. If safety is a top priority, you'll want to test drive a Mercedes-Benz SUV. Both vehicles can be outfitted with the latest technology, keeping you safe on the road.

Which SUV Is More Advantageous for Cottage Grove Residents?

Both the Mercedes-Benz GLA and GLB are exceptional SUVs that can deliver on the highest expectations for drivers. We don't believe that there is a clear-cut winner, as both vehicles have quite a bit to offer. Value-minded residents of Cottage Grove can benefit from the GLA and its exceptional powertrain and tech-savvy items.
