Sonoma generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the Sonoma's length or wheelbase jumps between consecutive model years the platform changed: a facelift moves a bumper by centimetres, a new generation moves the whole car — for the Sonoma that gives 4 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 1991-1993 | 490 cm | 300 cm | 1372 kg | - | - |
| 1994-1999 | 515 cm | 300 cm | 1568 kg | +25 cm | +196 kg |
| 2000 | 520 cm | 306 cm | 1463 kg | +5 cm | -105 kg |
| 2001-2003 | 520 cm | 312 cm | 1471 kg | +0 cm | +8 kg |
Between 1991 and 2003 the Sonoma gained 30 cm in length (+6.1%) and 99 kg in weight (+7.2%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the Sonoma that is 99 kg against 30 cm. Full dimensions by year →

Can a GMC Sonoma tow? Towing & payload
As a pickup, the GMC Sonoma is built to tow and haul. The exact maximum towing capacity and payload depend on the engine, drivetrain and whether it has the factory tow package.
What sets your Sonoma's tow & payload rating:
- Engine — a larger or turbocharged engine tows more than the base unit.
- Drivetrain & axle — 4WD/AWD and the axle ratio shift the rating.
- Tow package — the factory towing package (hitch, wiring, transmission cooler) raises the max.
- Payload & GVWR — GVWR caps the combined load; more passengers and cargo lower how much you can tow.
Exact towing capacity, payload and GVWR are added per engine, drivetrain and trim — decode your VIN above, or check the driver's door-jamb and hitch labels. Curb weight from vehicle specifications.
