I30 generations, and what changed

These boundaries are not copied from a brochure — they fall out of the measurements. Where the I30'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 I30 that gives 2 distinct generations below.

Between 1996 and 2001 the I30 gained 10 cm in length (+2.1%) and 85 kg in weight (+5.9%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the I30 that is 85 kg against 10 cm. Full dimensions by year →
