The 3500kg towing capacity is available across the range and represents a 500kg increase over the earlier MU-X . However , it ’ s important to keep the Gross Combined Mass in mind when towing at or near its maximum capacity , and adjust your vehicle payload accordingly . For example , if you were to tow 3500kg with the LS-T 4WD , payload in the vehicle would be limited to 225kg .
If touring with the family , a better bet might be to limit the weight of the van to , say , 3300kg in order to increase in-vehicle payload .
Isuzu says the new MU-X owes its increased towing capacity to a new ladder-frame chassis with uprated coil-spring suspension .
While the previous MU-X was not warranted for use with a weight distribution hitch , it ’ s a different story with the new version . In fact , a genuine Isuzu WDH is available with this model .
ENGINE
The new 4JJ3-TCX 3L common-rail four-cylinder turbodiesel engine is an evolution of the 4JJ1-TC HI that powered the previous-generation MU-X . Delivering linear and progressive torque across the entire rev range , it is the same engine that debuted last year in the new D-MAX ; however , it further benefits from technology designed to reduce nitrogen oxide and hydrogen sulphide emissions .
It offers a 10kW and 20Nm increase in power and torque over the MU-X ’ s previous engine . Midrange torque has also been improved , generating 400Nm from 1400-3250rpm . An impressive 300Nm is produced from just 1000rpm ( just above idle ), according to Isuzu . This should be of particular benefit to 4WDers who need that low-down torque for crawling up hills in low range .
Isuzu has increased the size of the fuel tank from 65L to 80L – a welcome change that was the result of direct feedback from customers . The manufacturer claims fuel consumption of 7.8-8.3L / 100km when driving – we will report on some fuel figures when towing a reasonably heavy van as soon as possible .
