G20 generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the G20'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 G20 that gives 2 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 1991-1996 | 445 cm | 255 cm | 1245 kg | - | - |
| 1999-2002 | 451 cm | 260 cm | 1332 kg | +6 cm | +87 kg |
Between 1991 and 2002 the G20 gained 6 cm in length (+1.3%) and 87 kg in weight (+7.0%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the G20 that is 87 kg against 6 cm. Full dimensions by year →
