Lexus' RX midsize luxury family SUV is the most popular model in its segment. It isn't the most affordable or most powerful option, but thousands of American car buyers are choosing the RX over rivals in 2026.
One of the Lexus RX's fiercest opponents is the Acura MDX, another Japanese midsize luxury model. Here's how the two match up in a head-to-head comparison.
The 2027 Lexus RX is the best-selling luxury SUV
The Lexus RX is refined, comfortable and it comes with great standard features. It has a quiet ride and high resale value. The RX is a practical family hauler.
Starting MSRP: $55,450
Horsepower/torque: 275 horsepower/317 pound-feet of torque
MPG: 22 city, 29 highway, 25 combined
Why I recommend it: The Lexus RX is dependable, so drivers planning long-term ownership can benefit from longevity
and low repair costs over time. It's significantly more affordable than rivals like the Mercedes-Benz GLE and BMW X5, but it can outlast German competitors.
I recommend the RX because it offers strong value over time. It may cost more than the average mainstream midsize SUV, but its cabin quality and advanced tech features make long ownership periods more enjoyable.
Acura's MDX is a well-rounded premium SUV
The 2026 Acura MDX offers athletic performance, V6 power and premium materials for a more affordable price than most competitors. It's a good daily driver with enough cabin and cargo space for families.
Starting MSRP: $51,800
Horsepower/torque: 290 horsepower/267 pound-feet of torque
MPG: 19 city, 26 highway, 22 combined
Why I recommend it: The MDX feels agile for its size thanks to a double-wishbone suspension and sharp steering. It's reliable making it a great choice for commuters who regularly travel with passengers.
I recommend the Acura MDX because it balances performance and practicality. You can also add all-wheel drive ($54,000) or upgrade to higher trims like the Technology Package ($57,200) for less than many base-model competitors.
Lexus RX vs. Acura MDX: Which midsize luxury SUV is better?
The most affordable option between the two SUVs is the MDX. Acura's SUV is also more powerful. The Lexus RX is the most efficient model of the two SUVs.
The MDX is a better choice for larger families as a three-row midsize SUV. It also has slightly more front-row legroom (41.6 inches) and second-row legroom than the RX. The Lexus RX has more base trunk space than the Acura MDX (29.6 cubic feet).
Acura's MDX also has a larger standard infotainment system (12.3 inches) than the Lexus RX.
Ultimately, the Lexus RX is the best choice for families of five or fewer because it's more durable and reliable. The MDX is ideal for larger families, offering solid performance specs, great cabin and cargo space and tech features.
