2024 Isuzu MU-X to get smaller capacity 1.9L turbo-diesel engine

By Evan Spence 5 Min Read

Australian Isuzu 4×4 dealerships will see the arrival of the 2024 Isuzu MU-X, from the second of April 2024. And there are some big updates this time around it seems. Namely, that the 2024 MU-X range will be offered with the choice of two turbo-diesel engines. We know what you’re thinking, don’t take our 3.0L Turbo-diesel engine! And you are right, Isuzu aren’t coming for the 4JJ3, yet. Nope, we are getting more options, not less.  

What’s the other engine?

The Australian 4×4 market will now also receive the RZ4E-TC 1.9-litre motor, which produces a claimed 110kW/350Nm. Both four-cylinder engines are bolted to an Aisin six-speed automatic transmission, with 4×2 or 4×4 drivetrain options available. 


The RZ4E-TC generates its 350Nm maximum torque output over a quarter (26.6 percent) of its available torque band, between 1,800-2,600rpm. Impressively, 85.7 percent of the maximum torque output (300Nm) is available across 71.6 percent of the torque band—from only 1,550rpm through to 3,700rpm— delivering strong mid-range torque across a 2,150rpm range in the middle of the band. The result is a wide and linear delivery of torque and strong mid-range response. We look forward to testing this new combo out in the following days, and as always, we’ll report our findings.

How much fuel will the 1.9L use? 

Return combined cycle fuel economy claims of just 7.4L/100km have been made by Isuzu, for the 1.9L engine. It will be available in three variants: LS-M 4×2, LS-M 4×4, and LS-U 4×4, positioning this more affordable and efficient engine option in the lower end of the variant list.

Towing with the 2024 Isuzu MU-X

The maximum braked towing capacity of an MU-X with the 1.9-litre engine is 3,000kg, with the Gross Combination Mass (GCM) coming in at 5,500kg. Gross Vehicle Mass (GVM) is dependent on drivetrain, with 4×4 models coming in at 2,800kg. 1.9-litre models have increased payload capacities, with the MU-X LS-M 1.9L 4×4 able to carry up to 735kg.

What Isuzu has to say 

“Value for money has always been at the core of our vehicles, and our team has worked hard behind the scenes to continue to offer that – regardless of the pressures from increased production and transportation costs that society has endured recently,” said Junta Matsui, Isuzu UTE Australia Managing Director. 

“Increasing the price of the 24MY MU-X range was a decision not taken lightly, with all options deeply considered.”

“We’re confident that value for money has been maintained across the 24MY MU-X range and the addition of the 1.9-litre turbo-diesel engine gives customers a more affordable option; not just at the showroom, but down the track, as it is up to 10 per cent more fuel-efficient than our 3.0-litre engine.” 

Would you buy the 1.9L MU-X?

While Isuzu says the new 1.9L motor is 10% more fuel efficient, saving you dollars over the 3.0L throughout your ownership period – is the $2000 savings over buying the proven 3.0L worth it to you? I can’t comment yet, as I haven’t driven the 1.9L (booked in for the 9th of April). But for me, $2000 is not enough of an incentive to buy the new motor over the much-loved 4JJ3. I’d love to know your thoughts on the topic. Would you pocket $2000 and better fuel economy (in theory) and take the 1.9L, or stay with the proven 4JJ3? Let us know in the comments section.
