The current Infiniti QX56 is 208.3″ long, 79.9″ wide, on a 121.3″ wheelbase, weighing 5,851 lb. At 17.4 feet it fits a standard garage and overhangs a street parking space.
Every Infiniti QX56 generation, measured
One row per generation. Watch the weight column — that is where most of the change happens, 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 |
QX56 year by year
Measured every model year, not just at generation changes — 10 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.

Will a QX56 fit
The practical question behind every dimensions search. A single-car garage in the US is typically 20 feet deep; a street parking space is about 18. 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. Lighter than typical for its size generally means better fuel economy and shorter stopping distances.

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.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and a table of forty near-identical rows helps nobody. Where a generation offered several body styles, the figures are the base measurements for that generation.
