|---|---|---|---|

IS generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the IS'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 IS that gives 4 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 2001-2005 | 449 cm | 267 cm | 1485 kg | - | - |
| 2008-2011 | 458 cm | 273 cm | 1656 kg | +9 cm | +171 kg |
| 2014-2020 | 467 cm | 280 cm | 1695 kg | +9 cm | +39 kg |
| 2023 | 471 cm | 280 cm | 1685 kg | +4 cm | -10 kg |
Between 2001 and 2023 the IS gained 22 cm in length (+4.9%) and 200 kg in weight (+13.5%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the IS that is 200 kg against 22 cm. Full dimensions by year →
