Suburban generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the Suburban'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 Suburban that gives 2 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 1985-1987 | 557 cm | 329 cm | 2050 kg | - | - |
| 1994-1999 | 558 cm | 334 cm | 2338 kg | +1 cm | +288 kg |
Between 1985 and 1999 the Suburban gained 1 cm in length (+0.2%) and 288 kg in weight (+14.0%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the Suburban that is 288 kg against 1 cm. Full dimensions by year →
