2026 BMW X3 vs. 2026 Mercedes-Benz GLC: Cargo, Grip, and Safety

If the 2026 BMW X3 and the 2026 Mercedes-Benz GLC are both on your short list, a side-by-side look at the facts can make your choice easier. Our team at BMW of Northwest Arkansas in Bentonville, AR, put the two compact luxury SUVs head-to-head so you can see where each one stands. You’ll see how they measure up in the areas that shape your everyday drive, and why the evidence keeps favoring BMW.

Cargo Space and Versatility

Fold the rear seats in the 2026 BMW X3, and you open up 67.1 cubic feet of cargo room, enough for camping gear or moving boxes without renting a trailer. With all five seats in use, the new BMW model still holds 31.5 cubic feet, so luggage stays out of your passengers’ laps.

The Mercedes-Benz GLC offers just 21.9 cubic feet behind the rear seats and 56.3 cubic feet with them folded. On a family road trip, that 9.6-cubic-foot gap behind the second row decides whether everything comes along.

Standard All-Wheel-Drive Traction

Every BMW X3 trim comes standard with xDrive® all-wheel drive. The system shifts power between the axles as conditions change, keeping you planted on rain-soaked pavement or a gravel road. The Mercedes-Benz GLC 300 matches the base BMW X3 with 255 hp and 295 lb-ft of torque, but it starts with rear-wheel drive, and 4MATIC® all-wheel drive is optional.

Want more muscle? The BMW X3 M50 xDrive produces 393 hp and 428 lb-ft of torque, so merging with a full load feels effortless.

Standard Driver-Assistance Technology

Driver-assistance features come standard on the BMW X3 rather than bundled into packages. Lane Keeping Assistant alerts you if you drift on a long highway stretch, and Active Blind Spot Detection flags a vehicle beside you before you change lanes. Forward Collision Mitigation with City Collision Mitigation can apply the brakes in stop-and-go traffic.

The Mercedes-Benz GLC includes standard active braking, blind-spot warning, and attention monitoring, while lane assistance is available. In the BMW X3, lane departure alerts come standard, so your protection on a long drive never hinges on an options list.
