What's the difference?
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?
Read on.
The march away from diesel power and towards a petrol-hybrid future in off-roaders continues. Okay, so it’s a full-sized Lexus we’re talking about, but the off-road credentials of the Toyota LandCruiser 300 Series-based Lexus LX have never been in question, have they?
The full-sized, super-lux Lexus LX might never see the Simpson Desert or the Old Telegraph Track, but that doesn’t mean it couldn’t tackle either with a fair degree of ease. So there’s no way Lexus would allow a new hybrid driveline to compromise any of that. Besides, this is the same driveline that will take the LandCruiser on its next step, so you better believe it’s the real deal.
Of course, the Lexus badge and somewhat frightening price tag also infer a high degree of plush and tech, and, let’s be honest, those elements are more likely to get a leading role in the LX’s day-to-day strut, as opposed to the walk-on part played by the off-road stuff.
So does all this make the LX one huge, high-tech mash up of conflicting priorities, then? That probably depends on how pragmatically you view motor vehicles generally, but one thing’s for sure, if the hybrid LX is paving the way for the next generation of LandCruiser powerplants and drivelines, then we’re all ears.
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.
Huge specification in terms of convenience and safety gear are matched by an equally huge range of abilities in this vehicle. As well as rock hopping with the best of them, this is also a phenomenal touring rig and a more-than-capable off-roader. Of course, whether you can see yourself clambering up the side of a muddy creek crossing in $202,000 worth of vehicle is a personal matter, but rest assured, the Lexus will do it if you ask it to.
In the case of the hybrid LX, however, the vehicle now has an extra dimension to cover off, and from what we can see, it does take the efficiency and running costs of the big wagon to a new, better place. Mind you, that may only be the case if diesel continues to cost a dollar-a-litre more than petrol at the bowser.
The shift to petrol power also brings with it a level of mechanical background noise that we’re not entirely sure fits the Lexus legend, while additions such as the camera-based rear-view mirror system seems to be a conversation starter rather than an actual improvement.
