BMW X3 VS. MERCEDES-BENZ GLC:WHICH LUXURY SUV IS BETTER?

2026 BMW X3 VS. 2026 MERCEDES-BENZ GLC: WHICH SUV IS BEST FOR YOU?

Compact, prestigious SUVs are incredible investments for your commute while staying versatile for every mile, so a BMW X3 vs. Mercedes-Benz GLC comparison is critical to making the best decision. Both models promise a compact yet capable cabin, but only one has the performance metrics to make your every mile memorable: the BMW X3. Before you visit Athens BMW, let's explore why the BMW X3 should be your next choice for a comfortable SUV.

PRICE & WARRANTY

While both models enter the scene with a similar warranty, the BMW X3 starts with a lower MSRP and has easier access to feature packages.

• BMW X3: The new BMW X3 for sale begins at a lower price than the Mercedes-Benz GLC -- including with the BMW SUV's standard AWD. Both models have option packages, and the BMW X3 offers them at a lower cost. It has a four-year/50,000-mile warranty.⁶
• Mercedes-Benz GLC: Whether it's the baseline model or additional performance-based trim levels (such as upgrading from FWD to AWD), the Mercedes-Benz SUV will cost you more than the BMW X3. However, it does have a comparable four-year/50,000-mile warranty.⁶

PERFORMANCE & DRIVING EXPERIENCE

Both models have engaging engines across their variants. But the BMW X3 has more standard towing capacity, similar acceleration, and standard AWD, while the Mercedes-Benz equivalent requires you to invest more.

• BMW X3: The standard BMW X3 has a 255-horsepower 2.0-liter turbocharged four-cylinder engine, just like the Mercedes-Benz equivalent. However, it also comes equipped with standard xDrive, a highly intelligent AWD system that powers the front or rear axle depending on your driving situation. In addition, a sturdier chassis lets the BMW X3 tow up to 4,001 pounds.⁴
• Mercedes-Benz GLC: While the Mercedes-Benz GLC has a standard 255-horsepower 2.0-liter turbocharged four-cylinder like the BMW X3, it can only tow up to 3,500 pounds.⁵

INTERIOR & COMFORT

The BMW X3 cabin is luxurious at every level, starting with high-quality Veganza upholstery and the intuitive BMW Interaction Bar. The Mercedes-Benz GLC can keep up in some areas but falls short in a few crucial ways.

• BMW X3: As you'll see in our BMW X3 interior overview, the BMW X3 offers amenities like easy access to a heated steering wheel in the Convenience package, Veganza upholstery with a straightforward path to Extended Merino leather, four-way lumbar support to keep you comfortable on long drives, and a minimalist design that keeps your cabin clean. You can add features like ventilated front seats separately to personalize the cabin.
• Mercedes-Benz GLC: The Mercedes-Benz GLC shares many elements with the BMW SUV, such as four-way lumbar support, but the big differences come in comfort allowances. A heated steering wheel, for example, requires the Winter Package – not a basic comfort package. Leather seating is more expensive.

SPACE & DIMENSIONS

While the Mercedes-Benz model offers fantastic legroom, the BMW X3 is the larger SUV, providing additional cargo space compared to the Mercedes-Benz GLC.

• BMW X3: The BMW X3 is the larger SUV, at a length of 187.2 inches. It also offers more cargo space, up to 67.1 cubic feet. See our BMW X3 vs. BMW X5 guide for more details on size.
• Mercedes-Benz GLC: The Mercedes-Benz SUV is a bit smaller, at 185.7 inches long, but has a significantly smaller cabin, providing a maximum cargo space of 56.3 cubic feet. It does have an edge in passenger space, with 40.7 inches of front legroom and 37.4 inches of rear legroom.

FEATURES & TECHNOLOGY

While both models boast a lineup of intuitive features, the BMW X3 goes the extra mile with easier access to upgraded tech and more screen space.

• BMW X3: Lease a BMW X3, and you'll enjoy a 14.9-inch central touchscreen, the BMW Interaction Bar, and easy access to a 15-speaker Harman Kardon® surround system.
• Mercedes-Benz GLC: The Mercedes-Benz SUV has a smaller touchscreen at 11.9 inches, puts its 15-speaker sound system behind a trim package, and lacks the same intuitive vehicle customization that you can find with the BMW X3 Interaction Bar.

SAFETY & RELIABILITY

While both models are considered safe, only the BMW X3 received the Top Safety Pick+ Award from the IIHS.¹

• BMW X3: The BMW SUV comes standard with features like Active Blind Spot Detection, Lane Departure Warning, and Frontal Collision Warning. It earned the 2026 Top Safety Pick+ award from the IIHS.¹
• Mercedes-Benz GLC: The Mercedes-Benz GLC boasts a similar lineup of features, but its lack of standard Blind Spot Warning and Lane Departure Warning means it only earned a Top Safety Pick award from the IIHS.¹
