The 2026 Acura MDX third row has 29.1 inches of legroom, making it the tightest row in the SUV. Every trim includes the walk-in access feature and the 50/50 split third row, but whether the space works for you comes down to your riders.
For Central Indiana families comparing three-row SUVs, we recommend starting with the dimensions and checking the fit together. Bring your riders along for a test drive.
The 2026 Acura MDX has the same interior dimensions across every trim.
| Measurement | First Row | Second Row | Third Row |
|---|---|---|---|
| Headroom | 38.5 in | 38.1 in | 36.2 in |
| Legroom | 41.6 in | 38.5 in | 29.1 in |
| Shoulder Room | 61.9 in | 60.3 in | 55.2 in |
| Hiproom | 59.3 in | 57.8 in | 40.6 in |
The third row has 9.4 inches less legroom and 17.2 inches less hiproom than the second row. The drop in legroom between the second and third rows is much larger than the 3.1-inch difference between the first and second rows.
The MDX includes 3rd-Row Access with One-Touch Smart Slide Walk-In as standard equipment on every trim. You do not need an Advance trim to get that access feature.
The MDX also includes 2nd-Row 4-Way Manual Seats and Multi-function 2nd-Row with Removable Middle Seat throughout the lineup.
Access and seated fit are separate questions. At your visit, have the people who will use the third row get in and sit there themselves. Looking back from the driver's seat does not answer either question.
The MDX has its least cargo space behind the third row, with larger volumes behind the second and first rows. These cargo measurements are the same across trims. Acura lists two cargo figures for each area, labeled Standard and Max.
| Cargo Area | Standard | Max |
|---|---|---|
| Behind Third Row | 16.3 cu ft | 18.1 cu ft |
| Behind Second Row | 39.1 cu ft | 48.4 cu ft |
| Behind First Row | 71.4 cu ft | 95.0 cu ft |
Every trim includes 3rd-Row Seats with 50/50 Split and Hidden Cargo Storage with Reversible Smart Lid. Choosing a different trim does not increase the cargo volumes in the table.
MDX trim choices change rear-seat equipment without changing the room dimensions. Third-row charging and second-row sunshades vary by trim.
| Trim | Third-Row USB-A Charging | 2nd-Row Side Sunshades (manual) |
|---|---|---|
| MDX | Not available | Not available |
| Technology | Not available | Standard |
| A-Spec | Not available | Standard |
| Advance | Standard | Standard |
| A-Spec Advance | Standard | Standard |
| Type S Advance | Standard | Standard |
As for which trim to pick, the room is identical on every MDX trim; if third-row charging matters, look at Advance, A-Spec Advance or Type S Advance. Second-row sunshades alone do not mean a trim includes third-row charging.
Every trim has second-row USB-C charging and 12-volt power outlets at the second-row console and in the cargo area.

If your riders need second-row-size legroom of 38.5 inches in the MDX third row on long daily drives, or need every seat in daily use, look at larger three-row vehicles. Moving to a different MDX trim will not add third-row room. Make the fit decision before choosing the extra equipment.
Bring the people who will ride in the MDX third row when you schedule a test drive. Have them check their fit in the back while the people using the other rows sit in their intended places. Let their fit check guide your choice.

The MDX has a walk-in access feature and 29.1 inches of legroom in the third row; its usefulness depends on your riders' fit. It is the tightest row in the vehicle, so a fit check with your riders is the practical next step. Bring them when you schedule a test drive rather than deciding from the front seats.
Third-row legroom in the MDX measures 29.1 inches versus 38.5 inches in the second row, a reduction of 9.4 inches. Hiproom is 40.6 inches in the third row and 57.8 inches in the second row.
No. The 2026 MDX has identical headroom, legroom, shoulder room and hiproom figures across its trims. Moving up the lineup changes equipment, including the availability of third-row charging, but it does not increase those dimensions.
The 2026 MDX has 16.3 cubic feet of Standard cargo volume and 18.1 cubic feet of Max cargo volume behind the third row. Both figures apply across trims.
Advance, A-Spec Advance and Type S Advance include third-row USB-A charging. MDX, Technology and A-Spec do not offer that feature. Second-row USB-C charging is standard throughout the lineup, so distinguish the charging location when comparing trims.
