Every Infiniti QX56 generation, measured
One row per generation. Watch the weight column — that is where most of the change happens for the Infiniti QX56, 220 lb of it since 2004, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.
| Generation | Length | Width | Height | Wheelbase | Curb weight |
|---|---|---|---|---|---|
| 2004–2010 | 207.5″ | 78.7″ | 78.7″ | 123.6″ | 5,631 lb |
| 2011–2013 | 208.3″ | 79.9″ | 76″ | 121.3″ | 5,851 lb |

Will a QX56 fit
The practical question behind every dimensions search, and for a 17.4-foot Infiniti QX56 it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the QX56 clears the garage by 1.6 ft. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 17.4 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 17.4 ft | Overhangs — expect a tight squeeze |
| Standard parking bay width | 8.5 ft wide | 6.7 ft | Room to open doors both sides |
Against cars of the same length
Compared with 406 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.
| Measure | This car | Typical car of this length | Difference |
|---|---|---|---|
| Width | 79.9″ | 75.6″ | +4.3″ |
| Wheelbase | 121.3″ | 119.7″ | +1.6″ |
| Curb weight | 5,851 lb | 4,433 lb | 1,418 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 5,851 lb the Infiniti QX56 is 1,418 lb heavier than typical for its size, which generally shows up as fuel economy and stopping distance.

How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 10 measured model years for the Infiniti QX56 between 2004 and 2013.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Infiniti QX56 fits into 2 rows instead of 10. Where a generation offered several body styles, the figures are the base measurements for that generation of the Infiniti QX56.
