The Outback XT/Wilderness’ standard 2.4 turbo 4-cylinder produces 5 more horsepower (260 vs. 255) than the GLC 300’s standard 2.0 turbo 4-cylinder hybrid.

As tested in Motor Trend the Outback XT/Wilderness 2.4 turbo 4-cylinder is faster than the GLC 300:

The flat cylinder configuration of the boxer engine in the Outback lowers its center of gravity, enhancing handling stability (That’s why Porsche uses boxer engines.). The GLC doesn’t offer a boxer engine configuration.

On the EPA test cycle the Outback gets better mileage than the GLC running its gasoline engine:

To lower fuel costs and make buying fuel easier, the Subaru Outback uses regular unleaded gasoline (premium recommended on Outback XT/Wilderness for maximum performance). The GLC requires premium, which can cost on average about 84.9 cents more per gallon.

The Outback has 5.6 gallons more fuel capacity than the GLC 350e’s standard fuel tank (18.5 vs. 12.9 gallons), for longer range between fill-ups. The Outback has 2.1 gallons more fuel capacity than the GLC’s standard fuel tank (18.5 vs. 16.4 gallons).

The Outback has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The GLC doesn’t offer a CVT.

The Outback Wilderness/Onyx XT has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the GLC; it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

For better maneuverability, the Outback’s turning circle is 2.6 feet tighter than the GLC’s (36.1 feet vs. 38.7 feet).

For greater off-road capability the Outback has a greater minimum ground clearance than the GLC (8.7 vs. 8.2 inches), allowing the Outback to travel over rougher terrain without being stopped or damaged. The Outback Wilderness’ minimum ground clearance is 1.3 inches higher than on the GLC (9.5 vs. 8.2 inches).

The Subaru Outback may be more efficient, handle and accelerate better because it weighs about 550 to 1100 pounds less than the Mercedes GLC.

To almost totally eliminate engine vibration in the passenger area, the Outback has liquid-filled engine mounts. The liquid helps further dampen engine harshness. The GLC uses conventional solid rubber engine mounts.

The front grille of the Outback 2.5i uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLC doesn’t offer active grille shutters.

The Outback has 2.1 inches more front legroom, .8 inches more front shoulder room, 2.1 inches more rear legroom and .8 inches more rear shoulder room than the GLC.

The Outback has a much larger cargo volume with its rear seat up than the GLC with its rear seat up (32.6 vs. 21.9 cubic feet). The Outback has a much larger cargo volume with its rear seat folded than the GLC with its rear seat folded (75.6 vs. 56.3 cubic feet).

The Outback’s cargo area is larger than the GLC’s in every dimension:

J.D. Power and Associates surveys of service recipients show that Subaru service is better than Mercedes. J.D. Power ranks Subaru 7th in service department satisfaction (above the industry average). With a 19% lower rating, Mercedes is ranked 17th.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Outback’s available exterior PIN entry system (not available on Outback Base). The GLC doesn’t offer an exterior PIN entry system, and its Mercedes-Benz Emergency Call can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

To improve rear visibility by keeping the rear window clear, the Outback has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLC only has an intermittent setting, so in a hard rain visibility isn’t as good.

Manual rear side window sunshades are available in the Outback to help block heat and glare for the rear passengers. The GLC doesn’t offer rear side window sunshades.

Consumer Reports® recommends the Subaru Outback, based on reliability, safety and performance. The Mercedes GLC isn't recommended.

The Subaru Outback outsold the Mercedes GLC by over four to one during 2023.
