Isuzu MU-X vs Toyota RAV4

What's the difference?

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.

The Toyota RAV4 Cruiser Hybrid 2WD model reaffirms why the RAV4 is so popular in Australia. It offers families space, convenience and features in a well-priced and handsome package. The cabin noise might be an ick for some but for everything else this model offers it could be overlooked.

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

In anticipation of the next-gen model, there hasn't been any design changes for the RAV4 - it remains a good-looking family SUV despite being a little heavy-handed with its angles.

Some external design highlights include garage friendly dimensions and a host of black accents across the body, including 18-inch alloy wheels that help to create an edgy kerb-side appeal.

Head inside and the RAV4 Cruiser offers a premium cabin-feel with its leather upholstery and large tech screens that headline the dashboard.

As always, there is a sense that design is based on functionality rather than style, which is typical of Toyota, but the simplicity makes the cabin relaxing to be in.

You’re not overwhelmed by touchpads or gadgets as can be the case in other new cars and there is a certain charm about that.

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors. There are also cupholders either side of the third row.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume and access sat nav).

Seats are comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is back there.

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows stowed away.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall. The MU-X’s full-size spare (bravo!) is attached to its undercarriage.

The RAV4 continues to impress with its practicality.

Access and comfort for both rows is excellent. The heat and cool functions for the front seats are perfect for all seasons and the two-position memory function on the driver’s side is handy if you often share driving duties with your partner.  

The rear row seating is well-padded and middle seaters will love the legroom the lower transmission tunnel offers. Head- and legroom is good in both rows, even for taller adults.

Amenities and storage are also great throughout the car.

Front rowers enjoy a decently sized middle console which I can squeeze my small handbag into, a glove box, two cupholders, two drink bottle holders, a phone tray and two shelves in the dashboard. You also get a sunglasses holder!

In the rear you get a single map pocket, two cupholders and two drink bottle holders, which is enough for my little family of three.

In terms of technology, you get a bunch and the usability is great.

The 10.5-inch touchscreen multimedia system looks really nice and is now the same system that Lexus uses, which is a big plus as it’s much easier to use than the previous Toyota one. The next-gen model should see this upgraded to a 12.3-inch system, which is more in line with its rivals.

You also get built-in satellite navigation, wireless Apple CarPlay and wired Android Auto. CarPlay maintains a strong connection.

There's a multitude of charging options throughout, including a USB-A port, four USB-C ports, a 12-volt socket and a wireless charging pad.

Rounding out the cabin is a boot that offers plenty of space with its 580L capacity and you get a temporary spare tyre, as well as, a retractable cargo cover.

However, the quality of the cargo cover isn't the best and it would be easier to use if it had a handle to grip onto.

The Cruiser model comes with a powered tailgate, which is always handy but the 'warning' alert as it opens or descends is very loud. Truck-reversing-beeping loud. Everyone will know when you open the boot!

The model line-up for the RAV4 consists of five variants with each available in front- or all-wheel drive.

The model on test for this review is the Hybrid Cruiser 2WD, which sits second-from-the-top in the line-up and is priced from $51,410 MSRP.

This price tag nudges it to the top of its rivals, the GWM Haval H6 Ultra Hybrid ($45,990 MSRP) and Nissan X-Trail e-Power ST-L ($50,490 MSRP) but the standard equipment for the Cruiser highlights its overall good value.

Premium features include leather-appointed upholstery, electric front seats with heat and ventilation functions, two-position memory function for the driver's seat, a sunroof and carpet mats.

Technology has had a good look in recently with the 10.5-inch touchscreen multimedia system now powered by the Lexus system (much easier to use) and a customisable 12.3-inch digital instrument cluster.

Other tech includes built-in satellite navigation, a nine-speaker JBL sound system, USB-A port, four USB-C ports, a 12-volt socket, a wireless charging pad, digital radio, digital rear view mirror, and a 'Toyota Connect' app with over-the-air updates.

Practical items include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, dual-zone climate control, a powered tailgate and directional air-vents in the rear.

For the grade level and compared to its rivals, the Cruiser more than holds its own.

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

All RAV4 models have a continuously variable automatic transmission and the same hybrid combination of a 2.5L four-cylinder petrol engine and electric motor which combine to produce up to 160kW of power and 221Nm of torque for front-wheel-drive models. 

The combo delivers decent power for an SUV of this size.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

The Toyota hybrid powertrain produces the lowest official combined fuel cycle figure compared to its rivals at just 4.7L/100km and the best theoretical driving range of up to 1170km courtesy of its 55L fuel tank.

After covering a mix of open-road and urban driving this week, the on-test figure is 5.5L/100km, which proves Toyota does hybrids well.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

The RAV4 Hybrid Cruiser 2WD is stupidly easy to drive which is one of its best qualities.

The driver is front and centre for design, so you don’t have to take your eyes off the road to twiddle with climate controls or changing your music. That makes the driving feel… well, cruisy.

Power delivery is mostly smooth and offers decent punch when you need to put your foot down. However, it can be laggy off the mark from a cold-start, so take care when crossing traffic.

Suspension feels well-tuned for our Aussie roads, even the regional ones, but never feels floaty. This is well-grounded but you do get some roll in corners.

A drawback is the cabin is annoyingly loud once you hit the open-road and there is a wind-whistle near the driver that drove me nuts.

There are also a lot of squeaky/rubbing noises when you hit bumpy roads. However, it is a refined experience around town, when engine noise is all but nil. The urban environment is where it shines. 

The steering is direct with a tight 11.4m turning circle, which makes the RAV4 easy to park. It also helps that the 360-degree view camera set-up is top-notch, which is not always the case for Toyota, and you get front and rear parking sensors too. 

The RAV4 has a maximum five-star ANCAP rating from testing done in 2019 and has seven-airbags but doesn’t have a front-centre airbag yet. 

It has high individual scores for protection, scoring 93 per cent for adult, 89 per cent for child, 85 per cent for vulnerable road-user, and 83 per cent for its safety assist systems.

The RAV4 has AEB with car, pedestrian and cyclist functions, operational from 10-80km/h (180km/h for car) but it is usual to see the system operational from 5.0km/h.

Standard crash-avoidance safety kit includes blind-spot monitoring, an SOS call button, emergency steering assist, driver attention alert, a rear occupant alert, rear and forward collision warning, rear cross-traffic alert and lane departure alert.

There's also lane keeping aid, traffic sign recognition, an intelligent seatbelt warning, adaptive cruise control with stop/go functionality, a 360-degree view camera system as well as front and rear parking sensors.

You also get a digital rear view mirror, which is great when you have compromised vision out the back window.

There are ISOFIX child seat mounts and three top tethers in the rear row. You might be able to get three seats across but two will fit best.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped price servicing covers the first five scheduled services for MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.

The RAV4 is offered with a five-year/unlimited km warranty, but you add two more years if you service exclusively with Toyota and on schedule.

There is a five-year capped-priced servicing program and it costs just $260 per service, which is very competitive for the class.

Servicing intervals are reasonable at every 12-months or 15,000km whichever occurs first.
