The current Infiniti G20 is 177.6″ long, 66.9″ wide, on a 102.4″ wheelbase, weighing 2,937 lb. Since 1991 it has grown 1% in length and gained 7% in weight. At 14.8 feet it fits a standard garage and fits a street parking space.
Every Infiniti G20 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 |
|---|---|---|---|---|---|
| 1991–1996 | 175.2″ | 66.5″ | 54.7″ | 100.4″ | 2,745 lb |
| 1999–2002 | 177.6″ | 66.9″ | 55.1″ | 102.4″ | 2,937 lb |
From 1991 to today the G20 gained 2.4″ of length (1%) and 192 lb of weight (7%). A modern compact often outweighs the mid-size car of a generation before.
G20 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.
| Model year | Length | Width | Wheelbase | Curb weight | Body styles |
|---|---|---|---|---|---|
| 2002 | 177.6″ | 66.5″ | 102.4″ | 1 | |
| 2001 | 177.6″ | 66.5″ | 102.4″ | 1 | |
| 2000 | 177.6″ | 66.5″ | 102.4″ | 1 | |
| 1999 | 177.6″ | 66.9″ | 102.4″ | 1 | |
| 1996 | 175.2″ | 66.5″ | 100.4″ | 1 | |
| 1995 | 175.2″ | 66.5″ | 100.4″ | 1 | |
| 1994 | 175.2″ | 66.5″ | 100.4″ | 1 | |
| 1993 | 175.2″ | 66.5″ | 100.4″ | 1 | |
| 1992 | 175.2″ | 66.5″ | 100.4″ | 1 | |
| 1991 | 175.2″ | 66.5″ | 100.4″ | 1 |
Will a G20 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 | 14.8 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 14.8 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 5.6 ft | Room to open doors both sides |
Against cars of the same length
Compared with 890 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 | 66.9″ | 70.9″ | -4.0″ |
| Wheelbase | 102.4″ | 104.3″ | -1.9″ |
| Curb weight | 2,937 lb | 3,311 lb | -374 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.
