Isuzu MU-X VS Mazda CX-9

Not a lot separates these two vehicles in terms of functionality or comfort because they share essentially the same interior with only a few differences.

The X-Terrain does, however, pip the LS-T overall with a slightly more premium look and feel to the cabin. Subtle touches such as red stitching in the cabin trim enhance the interior’s quiet charm.

Both cabins have a pleasant, familiar feel about them and are easy spaces in which to swiftly get comfortable and to quickly figure out where all controls are. And it’s easy to use those controls.

The X-Terrain has a black leather-accented trim, but there are plenty of durable plastic surfaces to cope with the messiness of real life.

The MU-X also has a leather-accented trim, but the same, practical plastic surfaces are present.

Charging options are numerous throughout the cabins of both vehicles – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places (in both vehicles) include recesses for your everyday carry gear, a suitably deep 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 in the MU-X for passengers riding back there.

There’s one seemingly minor but noticeable difference between the operation of the 9.0-inch multimedia touchscreen systems.

The MU-X has physical button options to activate some functions (including to switch on the audio system, to adjust volume, access sat nav etc), while those functions and others are activated/adjusted via on-screen buttons in the D-Max. No big deal, but you may prefer one of those approaches.

The load spaces on offer are obviously also a big point of difference in these vehicles.

The D-Max has a tub and it is shielded by a manually-operated roller-shutter cover that can be partially or fully opened or closed.

The tub is 1495mm long, 1530mm wide (1122mm between the wheel arches) and 490mm deep.

It is a double-walled tub, with an under-rail tub liner, two cargo tie-down points and it has tailgate assist.

The roller cover offers at least some degree of security from thieves, and protection from the elements (rain, mud, snow etc), but the drum (in which the cover is stored when it is rolled open) does impact the packability of the load space. 

Another option for D-Max owners is to get an Isuzu or aftermarket canopy, although that impacts the versatility of the load space because once it’s an enclosed area it makes it a bit more difficult to carry long and/or large loads in the tub.

The MU-X has the advantage here in terms of security and protection from the elements because its load space is fully enclosed from the factory.

The MU-X’s cargo area is 311 litres with all three rows in use; 1119 litres with the third row flat; and it’s 2138 litres with the second and third rows folded.

The rear cargo area has a cargo cover (so any potential crooks who look through your windows are unable to see your valuables), tie-down points and a 12V power outlet. There is a storage space under the rear cargo area floor and a tool storage space inside the driver’s side rear cargo wall.

Being an SUV that’s 5075mm long, 1969mm wide and 1747mm tall, practicality is arguably the most important thing for the CX-9, and with the option of six seats for the first time with the new Azami LE, it’s even more versatile.

All seven-seat grades have a 60/40 split-fold second row that manually slides and reclines the same as before, with only the Sport missing out on one-touch tumble operation, which makes accessing the 50/50 split-fold third row even easier, even if it’s still not graceful.

But the six-seat Azami LE is configured differently, given its second row has two captain’s chairs instead of a bench. That said, it operates in a very similar manner, just with power adjustment.

I still had around eight centimetres of legroom and four of legroom behind my 184cm (6'0") driving position, while the large transmission tunnel that’s a foot-space issue in seven-seat versions... isn’t.

One key difference with the very roomy and comfortable Azami LE is it only has four top-tether child-seat anchorage points, while all other grades have five thanks to their extra seat. Either way, four ISOFIX child-set anchorage points are split across the second and third rows.

Alternatively, the third row can be used by adults on shorter journeys, although they won’t have a lot of space to enjoy. Again, I'm 184cm tall and it’s tight back there, with no headroom or legroom on offer, but children will, of course, fare much better.

The CX-9’s boot is still pretty usable with all three rows in action, with 230L of cargo capacity available, but you can stow the two rear seats to get 810L in total.

And if you want maximum cargo capacity, the middle seats can also be folded, but not in the Azami LE, annoyingly.

Either way, the CX-9 doesn’t have a load lip but does have a flat floor, so loading bulkier items is a cinch, while two bag hooks and four tie-down points are on hand for securing loose items if they can’t fit in the double map pockets on the front seat backrests.

There are two cupholders in the third row, another two in the second row’s fold-down armrest (seven-seater versions) or large centre console (Azami LE), and another two in the first row’s larger centre console, while the front and rear door bins can also take bottles – and other knick-knacks.

All grades get USB ports in the first row, while the Touring and above also have them in the second row, and the GT and above also feature them in the third row. It’d be nice if there was no differentiation, though.
