Volkswagen Tiguan vs Isuzu MU-X

What's the difference?

If there is a catch to the discounted price of the Tiguan R Grid Edition it's that you'll have to live without leather seats and a head-up display, which is fine in my books as long as the dynamics and engine are the same, which they are in this special SUV.

What isn't ideal is the Tiguan R Grid Edition not having blind-spot warning or rear cross-traffic alert, which are standard on the regular Tiguan R.

Volkswagen had to make a hard decision there, and to be fair, the lack of availability of semiconductors is the reason behind this, not cost reduction.

If you are able to accept this, you'll have a relatively affordable SUV that can do both beast mode and family mode with impressive skill.

So, engine aside, not much new for the 2024 MU-X, but I can confidently say this: if you’re not towing big loads all of the time, then the 1.9-litre turbo-diesel won’t just save you cash at the dealership, but at the service station, too.

Some carmakers would go overboard in coming up with the styling of a 300+ horsepower mid-sized SUV, but not Volkswagen which is the master of understated, yet cool, design.

Any model wearing that R badge is special. On first glance the Tiguan R Grid Edition looks ready for a boardroom meeting but look closer and you'll see it's ready for battle.

Check out the Tiguan R Grid Edition's quad exhaust, its aggro R front bumper, the 21-inch 'Estoril' alloy wheels and the blacked-out grille.

The cabin is a premium looking place but like the insides of all Volkswagens it seems very business class, functional but not too fancy.

Thankfully the sports seats, while not Nappa leather as in the Tiguan R, stop it from all being a bit serious and grown up in here.

If you like the look of the 2023 Isuzu MU-X, then boy have I got good news for you, because the changes to the 2024 model occur under the bonnet, and nowhere else, really. That means you get the same simple, boxy exterior design, which emphasises capability over fanciness.

Yes, the MU-X design is more dependable than daring, but I reckon it works, with the three-row SUV cutting a fairly handsome figure, even if it is yet to receive the design tweaks just rolled out on the updated Isuzu D-Max.

Inside, though, it definitely presents as a little utilitarian, with some plastics that feel like they could survive a nuclear blast, and the 7.0- and 9.0-inch central screens both feel a little underwhelming by modern standards.

It all feels very comfortable and hard-wearing though, which is probably every bit as important, given the MU-X’s target market.

The Tiguan R Grid Edition is a five-seater, mid-sized SUV, it's not a seven-seater like the Tiguan AllSpace and there isn't an R version of that larger Tiguan. There is an R-Line Allspace, however.

Still, the Tiguan R Grid Edition is spacious with excellent headroom and even at 191cm tall I could sit comfortably in the second row behind my driving position.

This sounds really nerdy, but I love the way Volkswagen does door pockets - they're gigantic and I tend to throw my wallet, house keys and the mobile clutter from the rest of my life in there.

There are four cupholders on board, too (two up front and two in the second row).

The cargo capacity of the boot is big for the class at 616 litres. There are two levels to the boot floor, along with cargo hooks.

You'd expect a $64K SUV to have a power tailgate but the Grid Edition doesn't have one and this is down to the global semiconductor shortage.

The manual tailgate is fine, just remember to close it yourself - embarrassingly, on the launch I pressed the 'blank' panel where the button should be only to almost drive off with it open.

Also missing is wireless phone charging, but there are three USB ports (two up front and one in the rear).

Dark tinted side windows in the rear and climate control with directional air vents in the second row are big ticks on my own checklist for a good family car - the kids will be protected from the Aussie sun and travelling in a comfortable temperature. Never had these luxuries in my day...

Practicality has always been a sizeable MU-X perk, regardless of the engine. 

That starts with seven seats, and a back row where actual full-size humans can spend time — and there are not many three-row SUVs you can say that about.

I’m 175cm tall and while I wouldn’t pick row three as my first choice, I’d happily sit back there for short hops.

The middle row, too, is pretty spacious, though it is lacking in a few creature comforts, with just the air-con vents (but no temp controls) and a couple of USB ports to keep you company.

And remember when I said the brand was promising the 1.9-litre engine wouldn’t cost much in terms of capability? Well, Isuzu says the braked towing capacity for models fitted with the smaller engine is 3000kg, while the payload figure increases — now up to 735kg — mostly because the new engine is about 70 kilos lighter. Models fitted with the 3.0-litre turbo-diesel are still rated to tow 3.5-tonne. 

The MU-X stretches 4850mm in length, 1870mm in width and 1815mm in height and it sits on a 2855mm wheelbase, which means while there’s plenty of cabin space it’s not too ridiculous to park.

You’ll find 311 litres of boot space with all three rows in place, growing to 1119 litres with the second row folded flat and 2138 litres with just the front two seats in action.

Every MU-X model will offer at least 800mm in wading depth and 230mm ground clearance, too.

It has always been a value-packed proposition, the MU-X, and nothing much has changed for 2024, especially if you’re shopping for the smaller engine option. Be warned, though, there are price jumps for the carryover 3.0-litre turbo-diesel in most grades.

As usual in the ute-based SUV space, the complexity of trims and powertrains can be a little confusing, but the short version is the MU-X can be had in three trim levels, with the 1.9-litre engine offered on two of them, the LS-M and LS-U.

The LS-M opens proceedings with 17-inch alloy wheels, LED headlights, black sidesteps, keyless entry, cloth trim inside, a 7.0-inch central screen with Apple CarPlay and Android Auto and air-conditioning.

The LS-U then adds 18-inch alloys, roof rails, a leather steering wheel, a bigger 9.0-inch central screen, dual-zone climate control and a powered tailgate.

Finally, the flagship LS-T gets 20-inch alloys, leather seats that are heated in the front and remote engine start. 

All 4x4 models are plenty capable, too, with '4x4 Terrain Command', '2-High', '4-High' and '4-Low', a rear-diff lock and a 'Rough Terrain' mode which helps with grip and traction on slippery surfaces.

In that nose is 2.0-litre turbo-petrol four-cylinder engine making 235kW and 400Nm, and it's driving all four wheels through a seven-speed dual-clutch automatic.

A superb engine, a great transmission with lighting quick changes and brilliant traction from the all-wheel drive system.

And exactly the same as found in a regular Tiguan R. Volkswagen hasn't taken anything out here.

That makes the Tiguan R Grid Edition a 235kW family SUV with a 0-100km/h time of 5.1 seconds. That is quick.

How much fuel does it use? Less than you probably think.

Let’s focus on the new engine option here, with the 1.9-litre turbo-diesel delivering 110kW and 350Nm. They don’t sound like massive numbers, but Isuzu makes the point that the torque delivery is wide, with maximum grunt available from 1800rpm to 2600rpm, and 300Nm available from 1550rpm to 3700rpm, meaning there’s power there when you need it.

The new engine pairs with a six-speed Aisin tramsission and delivers power to two or all four wheels.

You'll need to feed your Tiguan R Grid Edition premium unleaded petrol and Volkswagen says that over a combination of open and urban roads you'll use 8.8L/100km.

That's not overly high considering this SUV isn't small, but how much fuel you use will really depend on how you drive it and no there isn't a hybrid or electric version.

A 58-litre tank means the official consumption figure translates to a driving range of around 660km.

Another perk of the smaller engine is a smaller fuel bill, with the 1.9-litre turbo-diesel promising to drink 7.4L/100km on the combined cycle - almost a litre less than the 3.0-litre 4x4 model, which is more like 8.3L/100km. 

Emissions drop, too, with the smaller engine rated at 196g/km of C02 combined, compared with 220g/km on for the 3.0-litre 4x4 model.

Impact on the hip pocket? Well, fewer trips to the service station for one. Isuzu says the 80-litre fuel tank should deliver almost 1100km of driving between refills.

If it's possible to drive in every condition over the space of eight hours then you can do it in Victoria. From grid-locked Melbourne CBD traffic in the hot morning sun to an awesome mountain run with the temperature dropping and mist rolling in.

So, in the space of that day the Tiguan R Grid Edition showed what it could do in pretty much every situation you'll be in.

Traffic is traffic, no matter what car you're sitting in but the Tiguan R Grid Edition is a comfortable place to be with those supportive sports seats, good visibility and light steering.

So, a normal Tiguan in everyday driving, right down to the comfortable and composed ride, even if this Grid Edition rolls on impossibly thin 255/35 R21 Hankook Ventus Evo S1 tyres.

But as we left the suburbs behind and pushed into the countryside towards Lake Mountain in Victoria's Alpine region, the 235kW turbo-petrol engine cleared its throat and made itself known.

Overtaking proved to be quick and simple on the highway, and hills were squashed easily by the grunt of that engine.

There's a little blue 'R' button on the steering wheel which puts the Tiguan R Grid Edition into 'Race' mode - more like Beast mode. The dampers firm up for flatter handling and the exhaust note changes to a deep rumble.

The Tiguan R Grid Edition isn't just powerful, it turns into corners beautifully, the transmission downshifting like a pro, the grip from the tyres impressive and the traction from all-wheel drive reassuring.

That same day I drove the T-Roc R Grid Edition as well, the little brother of the Tiguan R Grid Edition. I found the mini-monster T-Roc to be more fun and agile, but it is smaller and lighter with only a fraction less grunt.

Still there are not many mid-sized family SUVs that could outperform the Tiguan R Grid Edition at this price.

First things first, you can absolutely tow with the smaller MU-X engine. In fact, we attached a load weighing close to its 3.0-tonne maximum and the Isuzu just hunkered down and got to work.

It must be said, though, it’s nowhere near as effortless as when you have the bigger 3.0-litre turbo-diesel engine up front, which dispatches heavy loads clinically and easily.

The smaller option has to try harder and rev higher, and while it’s easy enough on downhill runs or flats, it’s noticeably slower when heading up hill.

It does demand the question of how often you’ll be attaching close to its rated maximum on the towball, though. If it’s often, the bigger engine is definitely for you. But if it’s occasionally, or your tow loads are lighter, you can definitely make do with the 1.9-litre option.

On the road, the 1.9-litre engine’s power delivery is actually pretty well suited to the MU-X. It’s not fast, of course, but the width of the torque band helps deliver grunt when you need it (to a point) especially in the low-end, and I reckon the whole experience is a bit smoother and quieter than with the bigger engine, too.

You are missing some of that effortless grunt, of course, and you still can’t escape the usual diesel noise that permeates the cabin, but the lower fuel use for lower power feels like a fairly decent trade. 

It won’t be for everyone, and cross-country travellers and towers will no doubt go for the bigger unit, but for everyone else the 1.9-litre is a pretty sensible option.

Full credit to Isuzu here for fitting every MU-X model, including the cheapest option, with its full safety kit, which starts with eight airbags in the cabin. 

From there, the active stuff kicks in, with the MU-X featuring AEB, 'Forward Collision Warning', adaptive cruise control (with 'Stop and Go'), traffic sign recognition, lane departure warning, 'Lane Departure Prevention', lane keeping assist, 'Emergency Lane Keeping', blind spot monitoring, rear cross-traffic alert and 'Trailer Sway Control'.

The MU-X has a maximum five-star ANCAP score from testing in 2022.

The Tiguan Grid Edition is covered by Volkswagen's five-year, unlimited kilometre warranty.

A five-year servicing plan costs $3200 (annual average $640) and you'll need to get the car serviced every 12 months or 15,000km.

Expensive servicing and no standard capped prices lowers the score here.

Every Isuzu MU-X model gets a six-year, 150,000km warranty, as well as five years of capped price servicing, and up two seven years of roadside assistant. 

The service are 12 months or 15,000km, and each service costs $449 per year, or a total $2245 over five years.
