The biggest difference between the Acura MDX and Acura RDX is that the larger MDX has three rows of seating and seats 7 versus the smaller RDX which only seats 5. Both vehicles produce fairly similar power numbers, but in a different way. The MDX has a naturally-aspirated V6, while the RDX uses a more compact turbocharged I4. The smaller engine in the RDX allows for a few more MPG while the bigger V6 in the MDX is why you’ll receive a superior towing capacity. Another engine-related difference is that there is an MDX Type S, which comes with a more powerful engine.
Both models come with a 10-speed automatic transmission and all-wheel drive is available for both as well. Since they are produced by Acura, both are loaded with tons of desirable standard features like a panoramic moonroof and full-LED exterior lighting.

Here we can see some of the bigger differences between the Acura MDX and Acura RDX, namely that the MDX is clearly the bigger of the two. The additional length and width allow the MDX to have a third row of seats while the more compact RDX has just 2 rows. That said, the amount of space per individual seat is pretty similar, with both offering generous room to comfortably settle in.
The best way to fully appreciate either or both of these SUVs is to experience them in person. Let Joe Rizza Acura help you find which one is right for you.
