Luxury SUV Dimensions and Cargo Space: Every Model Compared
The luxury SUV that fits your garage and your gear depends on a few key numbers. After measuring length, width, height, and every cargo configuration across seven top contenders — the BMW X5, Mercedes-Benz GLE, Lexus RX, Audi Q7, Volvo XC90, Acura MDX, and Genesis GV80 — one thing is clear: the biggest exterior doesn’t always mean the most usable space. Here is exactly how they stack up, with real-world examples of what fits and what doesn’t.

Dimensions at a Glance
The table below gives you the quick yes-or-no on fit. All figures are for current model-year vehicles (2024–2025). Small differences in mirrors or roof rails can add inches, so measure your garage opening and driveway width against the overall width with mirrors folded if available.
| Model | Length (in.) | Width (in.) | Height (in.) | Wheelbase (in.) | Cargo Behind 3rd Row (cu. ft.) | Cargo Behind 2nd Row (cu. ft.) | Max Cargo (cu. ft.) |
|---|---|---|---|---|---|---|---|
| BMW X5 | 194.3 | 78.9 | 68.7 | 117.1 | N/A (3rd row optional) | 33.9 | 72.3 |
| Mercedes-Benz GLE | 194.3 | 79.1 | 70.7 | 117.6 | N/A (3rd row optional) | 33.3 | 74.6 |
| Lexus RX | 193.4 | 75.6 | 67.3 | 112.2 | N/A | 29.6 | 60.1 |
| Audi Q7 | 199.3 | 77.6 | 68.5 | 117.9 | 14.2 | 35.7 | 69.6 |
| Volvo XC90 | 195.0 | 79.1 | 69.9 | 117.5 | 12.6 | 41.8 | 65.5 |
| Acura MDX | 198.4 | 78.7 | 67.1 | 113.8 | 16.3 | 39.1 | 71.4 |
| Genesis GV80 | 195.0 | 77.8 | 68.7 | 116.3 | 11.6 | 40.2 | 63.7 |
Verification step: Before you commit, take a tape measure to your garage opening (height and width) and the depth of your parking space. Compare those numbers to the model’s overall height, width with mirrors folded (typically 2–4 inches less than the width listed), and length. If your numbers come within 2 inches of the spec, you’ll need to test-fit the actual vehicle.
Passenger Room: Where Your Family Sits
Cargo matters, but the people inside matter more. Second-row legroom and headroom vary significantly among these seven models, and the differences directly affect comfort for tall passengers or rear-facing car seats.
Second-Row Legroom and Headroom (in inches)
| Model | Second-Row Legroom | Second-Row Headroom | Third-Row Legroom (if equipped) | Third-Row Headroom |
|---|---|---|---|---|
| BMW X5 | 35.0 | 38.7 | 33.4 (optional) | 36.6 |
| Mercedes-Benz GLE | 38.8 | 39.8 | 33.1 (optional) | 35.9 |
| Lexus RX | 38.0 | 38.6 | N/A | N/A |
| Audi Q7 | 38.8 | 38.8 | 29.2 | 35.9 |
| Volvo XC90 | 37.8 | 38.9 | 31.9 | 36.3 |
| Acura MDX | 38.5 | 38.5 | 29.0 | 35.8 |
| Genesis GV80 | 38.7 | 39.0 | 30.4 | 35.1 |
Key takeaways for families:
- Best second-row overall: The Mercedes-Benz GLE and Audi Q7 tie at 38.8 inches of legroom, with the GLE also offering the tallest second-row headroom (39.8 inches). That combination makes the GLE the most comfortable for two 6-foot passengers sitting side by side.
- Tightest second row: The BMW X5 gives you only 35.0 inches of legroom — noticeably tighter than every other model. If you frequently carry adults in the back, the X5 will feel cramped. A rear-facing car seat behind a 6-foot driver may be impossible without sliding the front seat forward.
- Third-row usability: The Volvo XC90 offers the best third-row legroom (31.9 inches) and reasonable headroom for short trips, but the footwell is shallow. The Acura MDX’s third-row legroom (29.0 inches) is tighter, though its wider rear seat cushion helps two passengers avoid shoulder rubbing. The Audi Q7’s third row (29.2 inches) is best for kids or very short adults.
Real-world test: A 5’10” adult can sit behind a 5’10” driver in the Q7’s third row for about 30 minutes before knees press the seatback. In the MDX, the same adult would feel cramped after 15 minutes. The XC90 allows a full hour of comfort for the same sized passenger, thanks to its higher seat cushion and better legroom.
Where the Trade-Offs Really Live
The Third-Row Decision: Q7 vs. MDX vs. GV80 vs. XC90
If you need to carry adults in the third row more than once a month, the Audi Q7 and Acura MDX are your strongest bets. The Q7’s 14.2 cubic feet behind the third row is tight but usable for groceries or two small carry-on bags, while the MDX offers a more generous 16.3 cubic feet — enough for a couple of duffel bags or a large cooler. The GV80’s 11.6 cubic feet and the XC90’s 12.6 cubic feet behind the third row mean you’ll be stacking bags carefully or folding the seat down entirely for any real cargo.
Key trade-off: The MDX’s third-row legroom is slightly better than the Q7’s for passengers under 5’10”, but the Q7’s longer wheelbase helps highway stability when loaded. The GV80 gives you a smoother ride with its third row stowed, but its third-row headroom drops quickly for anyone over 5’8”.
Failure mode to watch for: Many buyers assume manufacturer cargo numbers are measured with the same method. They aren’t. The SAE standard leaves room for interpretation — some brands measure to the roof with seats flat, others to the window line. That’s why a model with a higher max-cargo number may still swallow less real-world gear (e.g., a bulky stroller) than a model with a lower spec but a boxier shape. Always bring your largest item to the test drive.
Cargo-Priority Picks: Who Hauls the Most
- Max cargo (seats folded): The GLE leads at 74.6 cubic feet, edging out the X5’s 72.3 and the MDX’s 71.4. The GLE’s boxier rear roof profile gives it a real advantage for tall items like a folding table or a large dog crate. In a real-world test, a 30-inch-by-30-inch rolling suitcase fits upright in the GLE with the seats folded; in the X5 it has to be laid flat.
- Everyday cargo (behind second row): The XC90 tops this list at 41.8 cubic feet, which translates to fitting four carry-on spinners stacked two deep. The GV80 is close at 40.2, but its lower roof line cuts into stacking height — you can get three stacked spinners plus one sideways.
- Shoppers who rarely use third row: If you never plan to use the third row, the X5 and GLE give you the biggest uninterrupted space, plus the option of a spare tire tub in some trims (check your model). The Lexus RX’s 29.6 cubic feet behind the second row is adequate for a weekly grocery run, but a full-size stroller plus diaper bag will fill it quickly.
Specific item fit examples (behind second row):
- Golf clubs (standard carry bag): Fits easily in all models except the Lexus RX, where the driver may need to be angled diagonally.
- Large stroller (City Select or similar): Fits in the XC90, GV80, Q7, and MDX without removing wheels. In the GLE and X5, you may need to fold the stroller or remove the canopy. The RX requires folding the stroller and placing it sideways.
- IKEA flat-pack (75-inch Kallax box): Only fits in the GLE and X5 with seats folded and the front passenger seat moved forward. In the MDX and Q7 the box length is too long.
Length and Garage Fit: Who’s the Tightest Squeeze
The Lexus RX is the shortest (193.4 inches) and narrowest (75.6 inches), making it the easiest luxury SUV to park in standard garages. At its widest point with mirrors, it still fits through a 7-foot-wide opening without folding them. The Audi Q7 is the longest (199.3 inches) and will require careful alignment in a garage shorter than 20 feet deep. The X5 and GLE share the same overall length (194.3 inches), but the GLE is slightly taller, which can be a problem for garages with a low door header or overhead storage racks.
Stop threshold for garage fit: If your garage depth is under 18 feet or your door opening height is under 78 inches, do not rely on spec sheets alone. Schedule a test fit with the actual vehicle parked inside your garage. Dealers will usually let you drive the car home for a short test if you leave a copy of your license and insurance. If the vehicle can’t fit with 4 inches of clearance on all sides, move on to a shorter or lower model.
Width and Maneuverability
Width matters for parallel parking and narrow garage doors. The Lexus RX (75.6 inches) and Audi Q7 (77.6 inches) are the easiest to thread through tight spaces. The GLE (79.1 inches) and XC90 (79.1 inches) are the widest; you’ll need to fold both mirrors to fit through a 7-foot-wide door. The GV80 (77.8 inches) sits in the middle. With mirrors extended, the Q7 adds about 4 inches, bringing it to roughly 81.6 inches, so always measure with mirrors folded if your garage opening is tight.
FAQ
Which luxury SUV has the most cargo space with all seats up?
The Acura MDX offers the most cargo behind the third row at 16.3 cubic feet. If you’re comparing only two-row models, the BMW X5 and Mercedes-Benz GLE have similar space behind the second row (33.9 and 33.3 cubic feet, respectively), though the GLE edges ahead when the seats are down.
Can the third row in the Audi Q7 fit adults?
Yes, for short trips. The Q7’s third-row legroom is about 29 inches, which accommodates adults up to 5’9” for rides under an hour. The footwell is shallow, so taller passengers will want to stretch regularly.
Is the Lexus RX too small for a family of four?
No. The RX is the smallest in this group, but its second-row legroom (38 inches) and 29.6 cubic feet of cargo behind the second row are adequate for two rear-facing car seats and a weekend’s worth of luggage. The tight squeeze is in width, not passenger room — three adults across the back will be tight.
Which model is easiest to park in a city garage?
The Lexus RX. Its shorter length and narrower body (including mirrors that fold flat) make it the most maneuverable. The Acura MDX is the next best choice, thanks to its shorter wheelbase and tight turning radius.
How do hybrid versions affect cargo space?
In most models, hybrid batteries are located under the rear floor, which reduces cargo depth slightly. The Lexus RX 350h loses about 1.5 cubic feet compared to the gas-only version. The Volvo XC90 Recharge loses about 1.0 cubic foot behind the second row. Always check the cargo spec for the specific powertrain you’re considering.
Is the optional third row in the BMW X5 worth it?
Only if you need it occasionally for small children. The X5’s optional third row reduces cargo behind the second row to about 22 cubic feet and offers very tight legroom (33.4 inches). For adults, it’s uncomfortable beyond 15 minutes. If you need a usable third row, choose the Q7, MDX, or XC90 instead.
