Likes

Suitably refined on-road (for a 4WD wagon!)
Retains off-road capability
Eight-speed auto is good. (It should be in the 3.0-litre as well)

Affordability and equipment
Elegant outside, luxurious inside
Hugely quieter and more refined than before

Dislikes

Extra gruff
Laggy take-off
More power and torque wouldn't hurt

Driver-assist tech could use some Aussie road tuning
Hard to tell apart from previous design
NX 250 engine needs the open road to truly shine

2026 Isuzu MU-X Summary

Isuzu’s 3.0-litre MU-X has attracted plenty of fans over the years – and for good reason: it’s a seven-seat 4WD wagon packed with features, driver-assist tech and it has a decent 4WD set-up including a recalibrated rough terrain mode.

But the Japanese brand's 1.9-litre experiment has now officially ended – it’s a Gary-goner. So, for this test I’m driving its replacement: the 2.2L MU-X. This 4WD wagon has a, you guessed it, 2.2-litre engine – offering better claimed fuel consumption than the 3.0L, as well as an eight-speed automatic transmission and idle stop-start technology. And this MU-X has the same 3.5 tonne towing capacity as the 3.0-litre version, that’s 500kg more than the outgoing 1.9L MU-X.

So, how does this new 2.2L MU-X perform off-road? And does it make more sense as an adventure wagon than its 3.0L stablemate?

2023 Lexus NX250 Summary

As far as clichés go, attempting to make “a silk purse from a sow’s ear” couldn’t be more apt than when contemplating the original NX of 2014.

What was essentially the Lexus-fication of the vocal, fidgety and thirsty old Toyota RAV4 may have worked a treat sales-wise, but proved trickier when assessed against the lens of a BMW X3, Audi Q5 and Volvo XC60 rival.

The earliest NX just wasn’t refined enough.

This was especially true following the reborn RAV4 arrival in 2019, proving to be embarrassingly more competent – even compared to most luxury midsized SUV alternatives.

Now, finally, the NX redesign has followed suit, moving on to a variation of the Toyota’s stronger, quieter and more advanced TNGA architecture (dubbed GA-K) as a starting base.

Speaking of which, let’s dive straight into the least-expensive version, the NX 250 Luxury 2WD auto, to find out if the most popular Lexus model in Australia has finally found its mojo.

Verdict

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

Verdict

So, is the cheapest Lexus NX the grade you’d skip? Depends on where you live and drive.

If you’re urban based and bound, save up a bit more and go the petrol-electric hybrid; otherwise, out on country roads especially, the spirited and sporty NX 250 is more than up to the task.

Either way, though, the latest NX is finally fit to fight the other premium brands’ medium SUV efforts, head on and held up high. Welcome to big mid league, Lexus.

Ignore or underestimate at your own peril, everybody else.
