Every Infiniti Q45 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 |
|---|---|---|---|---|---|
| 1990–1996 | 200″ | 72″ | 56.3″ | 113.4″ | — |
| 1997–2006 | 199.2″ | 71.7″ | 57.1″ | 111.4″ | 3,882 lb |
Q45 year by year
Measured every model year, not just at generation changes — 17 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.

Will a Q45 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 | 16.6 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 16.6 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 6 ft | Room to open doors both sides |
Against cars of the same length
Compared with 743 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 | 71.7″ | 74″ | -2.3″ |
| Wheelbase | 111.4″ | 114.6″ | -3.2″ |
| Curb weight | 3,882 lb | 4,171 lb | -289 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.
