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 for the GMC Sonoma, 218 lb of it since 1991, 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 for the GMC Sonoma. Small moves inside a generation are facelifts; the jumps are the 4 new platforms below.

Will a Sonoma fit
The practical question behind every dimensions search, and for a 17.1-foot GMC Sonoma it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the Sonoma clears the garage by 1.9 ft. 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. At 3,243 lb the GMC Sonoma is 1,138 lb lighter than typical for its size, which generally shows up as fuel economy and stopping distance.

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, 13 measured model years for the GMC Sonoma between 1991 and 2003.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the GMC Sonoma fits into 4 rows instead of 13. Where a generation offered several body styles, the figures are the base measurements for that generation of the GMC Sonoma.
