Every Infiniti J30 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 |
|---|---|---|---|---|---|
| 1992–1997 | 191.3″ | 69.7″ | 54.3″ | 108.7″ | 3,527 lb |
J30 year by year
Measured every model year, not just at generation changes — 6 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.
| Model year | Length | Width | Wheelbase | Curb weight | Body styles |
|---|---|---|---|---|---|
| 1997 | 191.3″ | 69.7″ | 108.7″ | 1 | |
| 1996 | 191.3″ | 69.7″ | 108.7″ | 1 | |
| 1995 | 191.3″ | 69.7″ | 108.7″ | 1 | |
| 1994 | 191.3″ | 69.7″ | 108.7″ | 1 | |
| 1993 | 191.3″ | 69.7″ | 108.7″ | 1 | |
| 1992 | 191.3″ | 69.7″ | 108.7″ | 1 |
Will a J30 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 | 15.9 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 15.9 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 5.8 ft | Room to open doors both sides |
Against cars of the same length
Compared with 971 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 | 69.7″ | 73.2″ | -3.5″ |
| Wheelbase | 108.7″ | 111″ | -2.3″ |
| Curb weight | 3,527 lb | 3,918 lb | -391 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.
