There has been some confusion over Land Rover’s unusual, but not unheard of approach to GVM (Gross Vehicle Mass) for Australia. That’s because there’s different GVMs for different configurations. Today I checked with Land Rover, and they confirmed the GVMs for the Australian L663 Defender 110 are (direct copy-paste):
5 Seat – 3200kg
6 Seat – 3220kg
7 Seat – 3280kg
5 Seat 3230kg
Why the difference? This is where I make educated guesses, but of course 7 seat vehicles have to carry more human weight than 5 seaters so they need a greater payload or at least not reduced and the weight of the third-row seats eats into payload. The difference in GVM might be the chassis, or suspension tune, or electronics…all of the above are typically varied as GVM changes.
So, a good idea would be to buy a 7-seater and pull the rear seats out to gain an extra 80kg of payload over the 5-seater. And you don’t need engineering approval to reduce seats from 7 to 5 in Victoria!
The Defender’s GVM is used as an example in this video about 3500kg tow ratings:
