Isuzu MU-X Towing Capacity (Australia)

Recent MU-X configurations are rated up to 3,500 kg braked. The table below breaks down towing capacity, GVM, GCM and ball limit by year and variant, because in Australia the headline number is only one of four limits that must all hold.

Notes by range

2021-2026: Requires the genuine tow bar kit and an electronic brake controller. 4x2 GVM: 2,700. From Oct 2025 the new 2.2L matches these figures, giving the whole range 3,500 kg.

2022-2025: Dropped from the range in Oct 2025 in favour of the 2.2L.

2013-2021: 4x2: GVM 2,650 / GCM 5,650. The 3,000 kg rating held for the entire first generation.

The GCM catch on the current model

At the full 3,500 kg tow, the GCM of 5,900 kg allows the loaded vehicle (including ball weight) to weigh at most 2,400 kg. That is 400 kg below its GVM: weight you must leave out of the vehicle to stay legal while towing the maximum.

Ratings vary by engine, transmission, body and build date, and some require genuine tow kits or a brake controller. Treat these as accurate ranges and confirm your exact vehicle's plate, owner's manual or VIN-specific documentation before towing. Check your combination in the caravan towing calculator.

How to read Australian tow ratings

Four numbers govern every legal combination: the braked rating caps the trailer's ATM, the ball limit caps static download on the tow ball, the GVM caps the loaded vehicle (ball weight included), and the GCM caps vehicle and trailer together. Manufacturers advertise the first number; roadworthiness, insurance and the weighbridge care about all four.

Frequently asked questions

Which Isuzu MU-X tows the most?

The 3.0 second generation (2021 on) at 3,500 kg braked with the genuine tow kit and brake controller, which made the MU-X one of the cheapest 3.5-tonne wagons in the country.

Can a Isuzu MU-X legally tow a 3,500 kg caravan?

Recent configurations are rated to 3,500 kg braked, so yes on paper. In practice the caravan's ATM, the 350 kg ball limit and the 5,900 kg GCM all have to check out at once. Run your exact numbers through our caravan towing calculator before committing.

Is the braked rating the same as what I can actually hook up?

Not quite. The trailer's ATM (its maximum loaded mass) must stay under the braked rating, the ball weight must stay under the ball limit, and the loaded vehicle plus loaded trailer must stay under GCM. Any one of the three can be the binding constraint.
