Frequently Asked Questions

Common questions about comparing the 2025 Mercedes-Benz GLC-Class Coupe and 2026 Acura MDX.

How much more space does the Acura MDX offer compared to the GLC Coupe?

The 2026 Acura MDX is substantially larger overall, measuring 198.4 inches in length compared to the GLC Coupe's 187.6 inches, making it almost 11 inches longer. However, surprisingly, the Mercedes manages slightly more official cargo capacity at 19.2 cu ft versus the MDX's 18.1 cu ft.

Is the premium fuel requirement a major ongoing cost difference?

Yes, the GLC Coupe requires premium unleaded, directly impacting daily running costs due to its lower 26 combined MPG rating. While the MDX recommends premium and achieves 22 combined MPG, the GLC's fuel mandates and lower efficiency will likely result in higher long-term fueling expenses.

Which car has better transmission specifics?

The Acura MDX utilizes a 10-speed automatic transmission, potentially offering smoother highway cruising or closer gear ratios for its higher-horsepower engine. The GLC Coupe uses a 9-speed automatic transmission.

Why does the less expensive Acura have more horsepower?

The 2026 Acura MDX produces 290 hp from its base setup, significantly exceeding the 255 hp offered by the 2025 Mercedes-Benz GLC-Class Coupe. This power advantage makes the MDX the stronger choice for outright acceleration feel, even if it costs less.

Is the GLC Coupe's smaller size better for driving dynamics?

The GLC Coupe's tighter dimensions (187.6 inches long and 74.4 inches wide) generally translate to a nimbler feel in tight city environments. Conversely, the MDX is wider at 78.7 inches, which might feel more cumbersome during parallel parking or in narrow lanes.

How does the drivetrain compare between these two AWD crossovers?

The 2025 Mercedes-Benz GLC-Class Coupe comes standard with All-Wheel Drive (AWD) paired with its 9-speed transmission. For the 2026 Acura MDX, the listed drivetrain is Front Wheel Drive (FWD), meaning the AWD version might be an optional upgrade with different MPG figures.
