Acura MDX – Best for: Growing families or those living active lifestyles who need better performance for towing or more space for cargo

Placed side-by-side, it’s much easier to compare the unique advantages of both the Acura RDX and MDX to determine which is a better fit for you. Naturally, the smaller RDX offers a lower price tag compared to its larger three-row MDX counterpart. While the RDX comes standard with a potent 2.0-liter 4-cylinder engine and a capable all-wheel drive system, the MDX has a few additional options. You can opt for its standard 3.5-liter V6 or step up to the race-inspired MDX Type S and its muscular 3.0-liter turbocharged V6 for additional power. The MDX also offers your choice of standard front-wheel drive along with a proven all-wheel drive system as an option. While the MDX has the advantage in terms of horsepower, torque, and maximum towing capacity – the RDX is the more fuel-efficient option. Regardless of which model you prefer, both come standard with the proven Jewel Eye™ headlights that offer superior visibility and style.

Shifting our attention to the interiors of both the Acura RDX and Acura MDX, you’ll find plenty of key differences between the two. Perhaps the most notable difference between them is their seating capacities, with the two-row RDX offering space for 5 passengers and the three-row MDX boasting room for up to 7 occupants. If you need maximum space for your growing family or luggage, the MDX is likely the best fit for your needs. Interior dimensions remain plentiful regardless of which model you choose. Both models also come standard with automatic climate control systems along with a panoramic moonroof to enjoy fresh air and natural lighting inside the cabin. Another noteworthy difference comes when we compare cargo space.
