Acura RDX vs. MDX: Which Luxury SUV is Right for Your Seattle WA Drive?
For many drivers in the Seattle, WA, area, the decision to choose an Acura SUV is an easy one. Acura vehicles deliver the perfect blend of performance, luxury, and all-weather capability that the Pacific North West demands. The next, and perhaps most important, decision is choosing between two of the most popular models: the Acura RDX premium sport crossover and the Acura MDX premium performance SUV. While both SUVs embody the Acura commitment to quality, they are designed to serve distinctly different needs and lifestyles around the Emerald City. At Acura of Seattle, part of the O’Brien Auto Group, we want to help you clearly understand the key differences so you can select the perfect model for your daily commute and weekend adventures.
Which Acura SUV is better for families in the Pacific North West?
The most fundamental and defining difference between the Acura RDX and Acura MDX is their size and seating configuration. The choice often comes down to the number of passengers and the amount of gear you routinely carry.
The Acura RDX is classified as a compact luxury crossover that is perfectly suited for singles, couples, or small families. It offers two rows of seating with a total capacity for five passengers. Its size makes it exceptionally nimble for navigating the tight streets of downtown Seattle or finding street parking in Queen Anne.
In contrast, the Acura MDX is a midsize luxury SUV and the flagship of Acura’s SUV lineup. It comes standard with three rows of seating, accommodating up to seven passengers. If your life involves carpooling to Bellevue sporting events, taking the family to hike the Cascades, or simply needing flexible seating for guests, the MDX is the clear solution.
What are the performance differences between the RDX and MDX?
Power and efficiency are other areas where these two outstanding vehicles differentiate themselves. Your choice should align with your driving style and how you plan to tackle the varied terrain of the Pacific North West.

Acura RDX Performance
The Acura RDX comes standard with a lively 2.0-liter VTEC® Turbo 4-cylinder engine, delivering 272 horsepower and 280 lb-ft of torque. This engine is paired with a smooth 10-speed automatic transmission. This setup provides quick acceleration and a connected, sporty feel, making the RDX ideal for quick merges onto I-5 or navigating winding roads in the suburbs outside of Seattle. Its turbocharged nature provides excellent low-end power, which is great for the stop-and-go traffic you may encounter near the University District.

Acura MDX Performance
The Acura MDX features a naturally aspirated 3.5-liter i-VTEC® V6 engine, which produces 290 horsepower and 267 lb-ft of torque. While the MDX’s engine has slightly more horsepower, its V6 provides a smoother, more linear power delivery, perfect for comfortable long-distance cruising, such as a drive from Tacoma up to Bellingham. The MDX also utilizes a 10-speed automatic transmission, which ensures seamless shifts and strong power when carrying a full load of passengers and cargo up the steep hills found throughout the Seattle region.
How much cargo space does the RDX have compared to the MDX?
The difference in size directly impacts the amount of cargo volume available. For those of us living in the Seattle, WA area, whether we're loading up bulk goods from a local warehouse store or packing ski gear for a weekend trip to Stevens Pass, cargo space is a critical factor.
The compact RDX is surprisingly generous for its class, offering up to 79.8 cubic feet of maximum cargo volume with the rear seats folded down. This is plenty of space for most urban and suburban needs.
However, the larger Acura MDX offers significantly more overall cargo and passenger volume. With all three rows folded flat, the MDX boasts a maximum cargo capacity of up to 95.0 cubic feet. When the MDX is fully loaded with passengers, even the space behind the third row offers useful storage. If flexibility and maximum hauling capability are primary concerns, the MDX is the superior choice for O’Brien Auto Group customers.
Which RDX or MDX variant is best suited for performance driving in the Pacific North West?
For those in the Seattle area seeking a true performance upgrade, both models offer a Type S variant that radically changes the dynamic profile.
The RDX Type S maintains the 2.0-liter turbo engine but optimizes it for even sharper throttle response and tuning, creating a crossover that handles more like a sports sedan. It also adds performance-focused features like larger Brembo® front brakes.
The MDX Type S takes performance a significant step further by introducing an exclusive 3.0-liter Turbo V6 engine that generates 355 horsepower and 354 lb-ft of torque. This elevates the MDX to a true performance SUV, capable of thrilling acceleration and handling, perfect for spirited drives on Washington roads like the Olympic Peninsula loop. The MDX Type S also includes an adaptive air suspension system, which allows you to customize the ride height and comfort, providing an unparalleled luxury experience that excels on Washington’s diverse pavement.
Which Acura is better for commuting in downtown Seattle?
Both the RDX and MDX are available with Acura’s renowned Super Handling All-Wheel Drive™ (SH-AWD®) system. For drivers in the Pacific Northwest, especially considering our wet Seattle winters and occasional mountain snow, SH-AWD® is a critical safety and performance feature. This system actively sends power to the wheels that need it most, enhancing stability and traction whether navigating a slick I-5 during a downpour or heading up to the slopes on a snowy day.
While both offer exceptional handling, the RDX’s smaller footprint and slightly lighter weight often make it feel more agile and responsive, which is a major benefit when maneuvering through the busy, congested parts of the city. Parking is easier in the RDX. The MDX, while still remarkably capable, offers a more substantial, comfortable, and commanding ride that handles highway cruising beautifully. Our ultimate recommendation depends on whether your commute involves primarily city blocks (favoring RDX) or long highway stretches with heavy passenger loads (favoring MDX).
Do the RDX and MDX offer similar technology and safety features?
When looking at technology, both models reflect the Acura commitment to innovation and luxury. Both the RDX and MDX feature the AcuraWatch™ suite of advanced safety and driver-assist technologies as standard equipment. This ensures a high level of protection for you and your passengers, whether in rush hour traffic or on an open road trip.
However, the MDX, being the flagship SUV, often introduces the newest and most sophisticated features first, offering a slightly higher level of standard luxury and a wider array of available premium audio options, such as the ELS STUDIO 3D® Signature Edition system. The MDX also debuted Acura’s fully digital Precision Cockpit™, which provides a customizable driver display. While the RDX is incredibly well-equipped, the MDX provides a marginal step up in overall technological integration and premium material feel, particularly in the third row where RDX has no counterpart.
Ultimately, the choice between the Acura RDX and Acura MDX at Acura of Seattle is a personal one. If you prioritize maneuverability, efficiency, and a sporty feel in a luxury five-passenger package, the RDX is the perfect fit for the Seattle lifestyle. If your primary need is maximum space, three rows of seating, and flagship-level V6 power, the MDX will exceed your expectations. As part of the O’Brien Auto Group, we invite you to visit our showroom to experience the differences firsthand.
