A4 generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements.

|---|---|---|---|---|---|
| 1996-1999 | 452 cm | 262 cm | 1350 kg | - | - |

| 2005 | 458 cm | 265 cm | 1580 kg | +0 cm | -154 kg |
| 2008 | 459 cm | 265 cm | 1665 kg | +1 cm | +85 kg |

Between 1996 and 2023 the A4 gained 24 cm in length (+5.3%) and 298 kg in weight (+22.1%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the A4 that is 298 kg against 24 cm. Full dimensions by year →
