| 2026 Acura ADX | 2026 Acura RDX | 2026 Acura MDX | |
|---|---|---|---|
| Length (in.) | 185.8 | 187.4 | 198.4 |
| Width (in.) | 72.5 | 74.8 | 78.8 |
| Height (in.) | 63.8 | 65.7 | 67.9 |
| Wheelbase (in.) | 104.5 | 108.3 | 113.8 |
| Ground Clearance (in.) | 7.3 | 8.2 | 7.3 |
As you can see, the difference between the Acura ADX and RDX isn’t huge. However, there are still some important differences. The difference in wheelbase is greater than the difference in overall length, meaning the wheels are pushed out closer to the corners. On top of this, the RDX is wider and has almost an inch more ground clearance. These characteristics give it better handling in light off-road conditions if that’s important to you. The MDX is noticeably larger, which makes sense as the only three-row in the lineup. Which brings us to the interior dimensions that we’ll cover in the next section.

The Acura MDX is obviously the largest of the three Acura SUVs. Things like more cargo space and more passenger volume as a whole are exactly what you would expect. It’s also specifically wider than the other SUVs, so more shoulder room and hiproom also don’t come as a surprise. It’s also important to note that both of the smaller models (ADX and RDX) offer more front-row legroom. It’s not enough of a difference that you’ll really notice, but it does highlight that people who don’t often need a lot of cargo space or seating for seven might be just as comfortable in a smaller model. That’s the beauty of the Acura SUV lineup! You’ll have plenty of options to match your personal tastes, lifestyle, and driving preferences.
