The current GMC Sonoma is 204.7″ long, 68.1″ wide, on a 122.8″ wheelbase, weighing 3,243 lb. Since 1991 it has grown 6% in length and gained 7% in weight. At 17.1 feet it fits a standard garage and overhangs a street parking space.
Every GMC Sonoma 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 |
|---|---|---|---|---|---|
| 1991–1993 | 192.9″ | 65″ | 62.6″ | 118.1″ | 3,025 lb |
| 1994–1999 | 202.8″ | 68.1″ | 61.4″ | 118.1″ | 3,457 lb |
| 2000 | 204.7″ | 68.1″ | 63″ | 120.5″ | 3,225 lb |
| 2001–2003 | 204.7″ | 68.1″ | 62.6″ | 122.8″ | 3,243 lb |
From 1991 to today the Sonoma gained 11.8″ of length (6%) and 218 lb of weight (7%). A modern compact often outweighs the mid-size car of a generation before.
Sonoma year by year
Measured every model year, not just at generation changes — 13 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.
| Model year | Length | Width | Wheelbase | Curb weight | Body styles |
|---|---|---|---|---|---|
| 2003 | 202.4″ | 68.1″ | 118.9″ | 5 | |
| 2002 | 201.6″ | 68.1″ | 118.9″ | 9 | |
| 2001 | 201.2″ | 68.1″ | 118.5″ | 8 | |
| 2000 | 199.2″ | 68.1″ | 116.5″ | 10 | |
| 1999 | 198.8″ | 68.1″ | 116.1″ | 12 | |
| 1998 | 198.8″ | 68.1″ | 116.1″ | 12 | |
| 1997 | 200″ | 68.1″ | 117.7″ | 12 | |
| 1996 | 198″ | 68.1″ | 116.1″ | 8 | |
| 1995 | 198″ | 68.1″ | 116.1″ | 8 | |
| 1994 | 197.2″ | 68.1″ | 115.4″ | 7 | |
| 1993 | 188.6″ | 65″ | 116.5″ | 6 | |
| 1992 | 188.6″ | 65″ | 116.5″ | 6 | |
| 1991 | 188.6″ | 65″ | 116.5″ | 6 |
Will a Sonoma 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 | 17.1 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 17.1 ft | Overhangs — expect a tight squeeze |
| Standard parking bay width | 8.5 ft wide | 5.7 ft | Room to open doors both sides |
Against cars of the same length
Compared with 533 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 | 68.1″ | 75.2″ | -7.1″ |
| Wheelbase | 122.8″ | 118.1″ | +4.7″ |
| Curb weight | 3,243 lb | 4,381 lb | -1,138 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.
