It depends heavily on which year you buy at 3.5/5 — and the year you pick matters far more than the badge (best and worst years →).

GLS-Class generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the GLS-Class'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 GLS-Class that gives 2 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 2017-2019 | 513 cm | 308 cm | 2530 kg | - | - |
| 2020-2026 | 521 cm | 313 cm | 2545 kg | +8 cm | +15 kg |
Between 2017 and 2026 the GLS-Class gained 8 cm in length (+1.6%) and 15 kg in weight (+0.6%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the GLS-Class that is 15 kg against 8 cm. Full dimensions by year →
