Subaru Ascent vs. Mercedes GLB: Why the Mercedes GLB is the Better Luxury SUV

Comparing the Subaru Ascent and the Mercedes GLB: Let’s Start With Price

At first glance, the Subaru Ascent may seem like the more affordable choice for families looking for a practical SUV. Starting at around $35,000*, it promises functionality, safety, and room for up to eight passengers. However, once you add the premium features and technology that modern drivers expect, the Ascent’s price quickly climbs to $48,000 or more, putting it in the same range as a Mercedes-Benz GLB—a true luxury SUV with unmatched sophistication and value.

The Mercedes GLB starts at a competitive $39,800*, offering far more refinement and innovation, even in its base model. While the Ascent focuses on utility, the GLB seamlessly combines performance, luxury, and cutting-edge technology, setting a new standard for what an SUV can offer. In this detailed comparison, we’ll explain why the Mercedes GLB outperforms the Subaru Ascent in every key category.

Design: Functional vs. Stylish Luxury

The Subaru Ascent is practical, but its design reflects that focus. Its exterior is boxy and rugged, emphasizing utility over style. Inside, the Ascent offers durable materials and a functional layout, but even the higher trims feel utilitarian and lack the premium craftsmanship found in luxury vehicles.

The Mercedes GLB, on the other hand, is a stunning example of modern luxury design. Its exterior combines a sporty, boxy shape reminiscent of larger SUVs like the iconic G-Wagon with sleek lines and sophisticated accents. Inside, the GLB’s cabin is a masterpiece of craftsmanship, featuring premium materials like leather, brushed aluminum, and customizable ambient lighting. Even the base trim feels upscale and refined, far surpassing the Ascent’s interior quality.

Winner: Mercedes GLB. Its luxurious styling and attention to detail make it stand out as a true premium SUV.

Interior Space and Comfort: Practical vs. Premium

The Subaru Ascent offers a spacious interior with three rows of seating, accommodating up to eight passengers. It’s designed with families in mind, and while it does offer plenty of space, the seats feel firm, and the cabin lacks the refined comfort expected in higher-priced trims.

The Mercedes GLB also offers an optional third row, providing seating for up to seven passengers. While its third row is best suited for occasional use, the GLB excels in overall comfort and design. The seats are ergonomically designed, with available heating, ventilation, and memory settings for both driver and passengers. Thoughtful touches like dual-zone climate control, a panoramic sunroof, and ambient lighting create an upscale environment that makes every drive feel luxurious.

Winner: Mercedes GLB. While the Ascent offers more seating capacity, the GLB delivers superior comfort and luxury.

Technology: Basic Functionality vs. Cutting-Edge Innovation

The Subaru Ascent comes equipped with an 8-inch touchscreen and features like Apple CarPlay®, Android Auto®, and Subaru’s EyeSight safety suite. While functional, the system feels basic compared to what the Mercedes GLB offers. Upgrading to higher trims adds navigation and a premium sound system, but the tech still lacks the sophistication of a luxury vehicle.

The Mercedes GLB raises the bar with its advanced MBUX infotainment system. Featuring dual 10.25-inch displays, the system offers crystal-clear graphics, natural voice commands (“Hey Mercedes”), and augmented reality navigation. The GLB also includes cutting-edge safety technology like Active Brake Assist, Blind Spot Assist, and Crosswind Assist. Every feature in the GLB feels intuitive and designed to enhance both convenience and safety.

Winner: Mercedes GLB. Its MBUX system and advanced safety features put it leagues ahead of the Ascent.

Performance: Reliable vs. Refined

The Subaru Ascent is powered by a 2.4-liter turbocharged flat-4 engine, delivering 260 horsepower and paired with standard all-wheel drive. It provides reliable performance and good traction, especially in rough weather or light off-roading. However, its continuously variable transmission (CVT) often feels sluggish, and the driving experience lacks refinement.

The Mercedes GLB comes with a 2.0-liter turbocharged inline-4 engine producing 221 horsepower. Paired with an 8-speed dual-clutch transmission and available 4MATIC® all-wheel drive, the GLB offers a smooth, responsive, and engaging driving experience. Its suspension strikes a perfect balance between comfort and agility, ensuring that the GLB feels nimble in city driving and stable on long trips. For those seeking more power, AMG® models of the GLB deliver heart-pounding performance without compromising luxury.

Winner: Mercedes GLB. Its refined transmission and superior driving dynamics offer a far more enjoyable experience.

Price and Value: Affordable vs. Worth the Investment

The Subaru Ascent starts at a budget-friendly $35,000 for its base trim, but this version comes with limited features. As you move up to higher trims like the Ascent Touring, the price increases to $48,000 or more, bringing it close to the luxury SUV price range. At this point, buyers are paying near-premium prices for a vehicle that still feels utilitarian.

The Mercedes-Benz GLB starts at $39,800, offering luxury right out of the gate. Even the base model includes premium features like the MBUX infotainment system, a refined interior, and advanced driver-assistance technology. Opting for upgrades, such as the AMG® Line or 4MATIC® all-wheel drive, enhances the driving experience while still delivering far greater value compared to a fully-loaded Ascent.

For just a slightly higher investment, buyers get access to superior craftsmanship, advanced technology, and the prestige that comes with driving a Mercedes-Benz.

Winner: Mercedes GLB. The GLB offers far greater value for the price, delivering luxury and innovation unmatched by the Subaru Ascent.
