The Acura MDX and RDX are the automaker’s flagship vehicles and are staples of the luxury midsize SUV category. But when it comes down to choosing between the MDX and RDX, it comes down to needs more than wants.

What do we mean by that? Well, both models offer sleek styling, spicy performance, luxurious interiors, and plenty of high-tech features—all your wants. But the MDX has a passenger capacity of seven, rather than the RDX’s five. So if you and your family need the extra capacity, your decision may already be made for you.

But if that’s not enough information to sway you one way or the other, this article will expand on how the MDX compares to the RDX—and even how these iconic luxury midsize SUVs stack up against the competition.

Does Acura have a midsize SUV?

Acura only has five vehicles in its 2022 lineup, two of which are luxury midsize SUVs: the

three-row MDX

and the

two-row RDX

. The other three vehicles in the lineup are either sedans or coupes.

What makes a midsize SUV?

The answer may change depending on who you ask, but the most reliable metric seems to be the eye test: a midsize SUV is bigger than a compact SUV and smaller than a full-size SUV.

The MDX and RDX measure out at 198.4 inches and 187.4 inches, respectively. Some will argue that the MDX is a full-size SUV and the RDX is a compact crossover. Subjectivity aside, one thing is true: the MDX isn’t the biggest vehicle in the luxury SUV category and the RDX isn’t the smallest, so we think midsize is fair game!

Is the Acura Integra a midsize SUV?

No, the Acura Integra is the luxury automaker’s entry-level sedan. If you’re looking for more midsize SUVs, you may want to turn to Acura’s parent company, Honda.

MDX vs. RDX: which is the best midsize Acura SUV?

While their names only differ by one letter, there are plenty of specifications and features that make these midsize SUVs uniquely different. Let’s take a look at a side-by-side comparison of the Acura MDX and RDX.

2022 Acura MDX

MSRP range: $48,000 to $72,050

MPG: 17–19 city / 21–26 hwy

Seating for: 7 passengers

The 2022 Acura MDX is the first model of the fourth generation. It’s been applauded for addressing the confusing infotainment system and clumsy transmission of the third generation.

This new chapter for the Acura MDX also introduces the Type S performance trim, which includes a 355-hp turbocharged V6 with air suspension, Brembo brakes, Sport+ drive mode, and more! But if you don’t want to pay upwards of $70,000 for this sporty trim, the standard trim offers a 290-hp V6 that can still reach 60mph in a brisk 6.4 seconds.

There are copious amounts of space for first and second-row passengers, but the third row is mostly only suitable for kids. So as long as everyone isn’t crammed in, the great contour and elegant leatherette upholstery of the seats make long car rides comfortable and relaxing. And if you’re carrying cargo instead of people, the MDX can offer a maximum of 95 cubic feet.

Lastly, it’s hard not to be mesmerized by the galaxy-like front grille, a highlight among many exterior and interior design features.

Highlights include:

Tons of features on base model (power-adjustable front seats with heating, tri-zone climate control, traffic sign recognition, and more)

12.3-inch infotainment display with center-console-mounted touchpad controller

Light Truck Platform makes it agile for its size

Handsome styling

Exciting add-on packages

Available AWD

Weaknesses include:

Poor fuel economy

Third row cramped for adults

Steering and braking are over-assisted

2022 Acura RDX

MSRP range: $40,600 to $53,300

MPG: 21–22 city / 26–28 hwy

Seating for: 5 passengers

Even though the Acura RDX is the 5-seat cousin of the 7-seat MDX, it holds its own regarding cargo space—offering almost 80 cubic feet. The RDX feels like you're getting a whole lot of SUV for not a ton of money, in more ways than just size!

There’s no need to open your wallet for extra power, either. Even the base model is equipped with a sporty 272 hp 2.0L Turbo Inline-4 engine! Partner that with engaging handling dynamics and you get a spirited driving experience across all trim levels. That said, the engine sound is piped into the cabin, which some performance enthusiasts may be opposed to.

The aerodynamic compact build and lighter body also help the Acura RDX achieve better fuel economy than the MDX. But after that, these two flagship midsize SUVs share a lot in common in regards to their premium features and luxurious design.

Highlights include:

Great value for a luxury vehicle

Long list of standard features (10.2-inch infotainment system, wireless connectivity, heated power-adjustable front seats, AcuraWatch safety suite, and more)

Exciting add-on packages

Entry-level engine doesn’t feel so entry-level

Better fuel economy than the MDX

Weaknesses include:

Low towing capacity for an SUV

Only one engine available

2022 Acura vs. 2022 Acura comparison

	2022 Acura MDX	2022 Acura RDX
Starting MSRP	$48,000	$40,600
Seating capacity	Seven	Five
Fuel economy	22 combined mpg	24 combined mpg
Base engine	3.5-liter V6 (290 hp, 267 lb-ft of torque)	2.0L Turbo Inline-4 (272 hp, 280 lb-ft of torque)
Total cargo volume	71.4 cubic feet	58.9 cubic feet
Maximum towing capacity	3,500 to 5,000 lbs	1,500 lbs
NHTSA safety rating	Five stars	Five stars
Reliability scores	77/100 (J.D. Power)	80/100 (J.D. Power)

The bottom line

Again, it comes down to wants and needs. If you need extra passenger space and more towing capacity, go with the MDX. If you want sportier performance and better fuel economy, the RDX will be a better option.

But regardless of your needs, both models have premium amenities and high-end design features that will not leave you wanting more. These are simply two of the best vehicles in the luxury midsize SUV category.
