Acura MDX or RDX: which SUV fits South Jersey drivers and families?
Choose the Acura RDX if you drive into Philadelphia alone or with one or two passengers, and choose the Acura MDX if your family needs a third row. The MDX seats seven and the RDX seats five, and that is the one difference that decides it.
Elite Acura sells both from Maple Shade, and most South Jersey households headed into Philadelphia know which side of that line they sit on before they walk in. Everything else, from fuel to towing to price, follows from the seat count.
Keep reading below, then schedule a test drive in Maple Shade. Bringing your own numbers to the lot settles this faster than any spec sheet.
The RDX fits a solo or couple’s daily drive into Philadelphia
If most of your miles are a commute over the river, the RDX wins on fuel. The EPA certifies the RDX at 23 mpg combined, against 19 to 22 for the MDX across its trims.
Those miles include a bridge. The Delaware River Port Authority charges passenger cars a 6.00 dollar toll, collected westbound into Pennsylvania (Delaware River Port Authority, 2024). Commuters who make 18 or more round trips in a month can earn an 18.00 dollar account credit, though they have to enroll in it (Delaware River Port Authority, 2026). A daily crosser repeats the fuel savings on every one of those trips.
The RDX also sits higher. Its ground clearance is 8.2 in, against 6.7 in to 7.3 in for the MDX. That matters in a part of New Jersey where NOAA puts average annual precipitation at 49.32 inches in Moorestown, next door to Maple Shade (NOAA National Centers for Environmental Information, 2020).
The RDX makes 272 hp. The MDX runs from 290 hp to 355 hp, so a buyer who wants more power has a reason to look at the MDX even without the family.
A family of five or more in Philadelphia needs the MDX third row
The MDX seats seven and the RDX seats five. If your household in Philadelphia, Cherry Hill or Maple Shade regularly carries more than five people, the choice is made and the RDX is out.
The extra seats come with extra room behind them. The MDX holds 39.1 cu ft of cargo behind the second row and 95 cu ft at its maximum. The RDX holds 29.5 cu ft behind the second row. Third-row legroom in the MDX is 29.1 in, which suits kids and shorter trips.
The second rows are close to even, at 38.5 in of legroom in the MDX and 38 in in the RDX. So a family of four does not need the bigger vehicle for the back seat. The MDX earns its place when the third row, or the 10.0 cu ft of extra space behind the second row, gets used every week.
The table puts the figures side by side, and it shows the MDX ahead on seats, power, cargo and towing, and the RDX ahead on fuel and ground clearance.
| Figure (2026 model year) | Acura MDX | Acura RDX |
|---|---|---|
| Seats | 7 seats | 5 seats |
| Cargo behind the second row | 39.1 cu ft | 29.5 cu ft |
| Maximum towing, properly equipped | 3,500 lbs to 5,000 lbs | 1,500 lbs |
| Horsepower | 290 hp to 355 hp | 272 hp |
| Ground clearance | 6.7 in to 7.3 in | 8.2 in |
| EPA combined mpg, gasoline | 19 to 22 | 23 |
| MSRP, manufacturer’s suggested price | $51,800 to $75,850 across 8 trims | $45,100 to $54,850 across 5 trims |
A weekend trailer from Maple Shade points to the MDX
If you tow, the MDX is the better choice for pricing between the two. The manufacturer rates the MDX at 3,500 lbs to 5,000 lbs, properly equipped, and the RDX at 1,500 lbs.
The range matters. The MDX’s 3,500 lbs belongs to its lower trims and its 5,000 lbs to the others, so a buyer with a specific trailer should match the trailer to the trim before choosing. The RDX’s 1,500 lbs covers a light utility trailer and little more.
If you tow a few times a year or never, this section does not decide your purchase, and the daily drive section above does. If you tow most weekends, nothing else in the comparison outweighs it.
What an MDX or RDX costs a Philadelphia buyer who registers in New Jersey
The RDX starts $6,700 below the MDX. The manufacturer’s suggested price is $45,100 for the RDX SH-AWD, the lowest of its five trims, and $51,800 for the MDX FWD, the lowest of its eight. The RDX tops out at $54,850, and the MDX climbs to $75,850. Those are the manufacturer’s suggested prices, not our prices.
A New Jersey registration adds a state charge on top of the sticker. New Jersey sets passenger vehicle registration by weight class and model year, and a car over 3,500 pounds pays $71.50 or $84.00 (New Jersey Motor Vehicle Commission, 2026). The state’s other costs depend on you and the vehicle you pick, so ask us to walk through them on the specific vehicle.
If the budget is the first question, the RDX answers it with a lower starting price and better fuel economy. If space is the first question, the MDX’s higher starting price buys the seats.

Owners tell us what the visit is like. In a September 2026 Google review of Elite Acura, Lorraine C. wrote: “I came in without an appointment when my MDX shut down on the road. The service agent that I dealt with gave me his complete attention throughout my experience. I really appreciated his honesty with me.”
Albert H. left a September 2026 Google review of Elite Acura about the other model: “Went in to look at the new 2020 RDX. Met Joe Inglima and he made the whole experience painless. Walked out with a car.”
A Google review of Elite Acura from August 2026 comes from Tamara M., an MDX owner: “My car buying experience was the BEST I’ve ever had at Elite Acura. Scott G., my car salesman couldn’t have been any more knowledgeable and helpful in my search for a car. He along with Jake A. of the service department were OUTSTANDING!! All of my questions were answered promptly, and the whole process went smoothly. Thank you, Scott, Jake, and Elite Acura!! I love my MDX!!”
Frequently asked questions
Do the MDX and RDX carry the same warranty?
Yes. Both come with a 4-year / 50,000-mile basic limited warranty and a 6-year / 70,000-mile powertrain limited warranty. The warranty will not tip the decision either way.
Is the second row different enough to matter?
Barely. Second-row legroom is 38.5 in in the MDX and 38 in in the RDX, so a family of four fits comfortably in either. The third row is what separates them.
Does a new MDX or RDX need an emissions inspection in New Jersey?
A car less than five model years old is eligible for a five-year exemption, and New Jersey inspects an ordinary passenger car for emissions every two years after that (New Jersey Motor Vehicle Commission, 2022). A new MDX or RDX sits inside that exemption, so you will not face one early in ownership.
Is a certified pre-owned MDX or RDX worth a look?
Acura Precision Certified covers 2021 to 2026 vehicles with fewer than 80,000 miles, and includes a 182 point inspection by an Acura Certified Technician and a $0 deductible for covered repairs (Acura Certified Pre-Owned program site, 2026). The same MDX-or-RDX question applies, so decide on seats first and then look at what is on the lot.
Which one has more power?
The MDX. It makes 290 hp to 355 hp depending on trim, and the RDX makes 272 hp. If you want the strongest MDX trim, ask us which trim reaches 355 hp.
The RDX fits the Philadelphia commute and the MDX fits the Philadelphia family
The RDX is the right Acura for the Philadelphia commuter, the couple and the household of up to five, because it costs less to buy and less to fuel. The MDX is the right Acura for the family that needs seven seats or tows on weekends, and the seats and the towing rating are what that extra money buys. If you are somewhere in between, count the people you carry in a normal month and let that number choose. A South Jersey buyer who wants the car serviced where it was bought can make either choice with us, and the service department that earned the reviews is the same one that will look after your SUV.
