S4 generations, and what changed

These boundaries are not copied from a brochure — they fall out of the measurements. Where the S4'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 S4 that gives 6 distinct generations below.

Between 1993 and 2023 the S4 gained -12 cm in length (-2.5%) and 33 kg in weight (+1.9%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the S4 that is 33 kg against -12 cm. Full dimensions by year →
