BMW X5 vs Isuzu D-Max

What's the difference?

This is a luxurious prestige five-seater brimming with BMW’s latest design and technology that’s not only practical for weekly family duties but can also embrace spirited driving with the push of a button. A great all-rounder for families that like a sporty edge. 

The new engine makes the D-Max a much more likeable ute than it already was, which is high praise.

It’s smoother and quieter and makes for a more pleasant drive. The added efficiency is a bonus both for your wallet and Isuzu’s emissions credits.

The 3.0-litre engine will probably remain the favourite, but anyone who test drives a 2.2L might even be tempted to opt for the smaller unit. Isuzu sure hopes so.

The latest front-end design features subtle revisions to BMW’s signature 'kidney' grille theme, highlighted by slimmer matrix LED headlights with chevron-shaped DRLs that incorporate the turn indicators.

There’s also an ‘iconic glow’ function, which illuminates the twin-grilles at night in-sync with the external courtesy lights when approaching and departing the vehicle. Lower front air-intake and tail-light treatments have also been revised.

The dash features a new curved instrument panel. Based on BMW’s latest generation 'iDrive' operating system, it consists of a 12.3-inch driver’s info display and 14.9-inch control display presented across the same seamless glass surface.

The control display’s touchscreen functionality has allowed dash buttons and switches to be minimised.

This new design dash has a blend of synthetic leather trim and dark brown/high-gloss woodgrain surfaces, along with new LED ambient lighting and gear-selector design.

The rear seat is sumptuous and spacious, even for someone my height (186cm). There’s ample knee and headroom and it can seat three kids in comfort, but for adult passengers wanting that 'business class' feel it would be ideal for two.

My only criticism of the new instrument display is that with more than 30 applications displayed on the expansive control screen, it can be distracting at times trying to visually locate and operate these functions while driving.

And, depending on sun angle, there were also complaints from different front seat passengers on different days about blinding glare caused by the dash’s high-gloss woodgrain inserts. Fortunately, the driver is unaffected by these reflections.

The look of the D-Max depends on the grade you end up with, but the 2.2-litre SX and X-Rider variants down the lower end of the model-run are still pretty standard-looking utes. Inside and out.

You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated. 

The black trim (and extra features) that comes with the LSM X-Rider as opposed to the SX is worth it if you’re keen to get a 2.2-litre-powered D-Max for the family rather than one for a fleet as it just elevates things slightly.

Inside, it also means nicer cloth, and not having the vinyl flooring looks a little less ‘farm ute’.

With its 2165kg kerb weight and maximum allowable weight of 2885kg, our test vehicle can legally carry up to 720kg.

That should be ample for five adults (even better for kids) and their luggage, of which up to 100kg can be carried on the roof rails using a rack or roof box (both in BMW's accessory range).

Powered upper and lower tailgates provide good access to the luggage area, which is carpeted and equipped with a roll-out privacy screen, load securing hooks, a 12-volt accessory outlet and a first-aid kit stored behind a removable side panel.

The space-saver spare and tools are stored below the hinged load floor, so all luggage must be removed to access them.

Internal luggage space with the rear seat upright is 650 litres (0.65 cubic metres) which expands to 1870 litres (1.87 cubic metres) with the rear seat folded flat.

A useful load-carrying feature when the rear seat’s backrest is upright is a hinged centre section that folds forward and flat to carry long and narrow items.

These can stretch all the way from the tailgate to the dash if need be, which could be handy for carting anything from skis to home hardware purchases (firmly secured, of course).

It’s also rated to tow up to an impressive 3500kg of braked trailer, which matches the class benchmark for one-tonne utes.

However, given that tow-ball download (TBD) is usually around 10 per cent of trailer weight, the X5’s maximum TBD rating of only 140kg could be a challenge if 3500kg towing is required.

Front of cabin storage includes a big bottle-holder and bin in each front door, a glove box and on the right-hand side of the dash a pull-out driver’s bin, both of which are felt-lined.

The centre console, in addition to its wireless phone-charging pad, USB-A port and 12-volt outlet, has two small-bottle/cupholders up front and a large box at the rear, housing a USB-C port and topped by a padded dual 'brochure fold' lid that double as an elbow-rest for driver and front passenger.

Rear seat storage includes a large-bottle holder and bin in each door and pockets on each front seat backrest. The rear of the centre console has two storage nooks for small items in addition to its air-vents, two USB-C ports and a 12-volt outlet. There’s also a handy tablet-mount and USB-C port on each front seat backrest, which is great for long trips.

Folding down the rear seat’s centre armrest reveals two pop-out small-bottle/cupholders. And under its hinged lid is a hidden felt-lined compartment that’s ideal for storing slim screened devices away from prying eyes.

The D-Max remains straight-forward inside, given nothing has changed with the update aside from the 2.2-litre engine and the addition of stop-start - there’s a button for that now.

The interior and usability of the D-Max, especially in the lower-end variants where the 2.2L engine is available, is focused on the basics.

Tech remains at a relative entry point, where the 8.0-inch screen and its software feel outdated but do everything you need. Plus of course there’s the phone mirroring workaround.

The D-Max is comfortable and spacious enough, there’s also physical buttons for everything including media and climate settings, and adjustability in terms of the seating position means not needing to reach.

In dual-cab versions, there’s enough space for an adult to sit in the second row behind another adult, so the D-Max also holds its own as a family hauler. Tick.

Importantly, Isuzu is now able to claim a 3500kg braked towing capacity across the full D-Max range thanks to the new 2.2-litre engine.

Pricing is up across the board for D-Max (and its MU-X sibling) regardless of drivetrain, but we’ll stick to the 2.2-litre variants here to stay on track.

Most of the lower-level D-Max variants are $1500 more than the previous equivalent, and with the manual gearbox dropped, the cheapest grade is the 4x2 single-cab chassis SX with a 2.2L engine at $36,200 before on-roads.

You can get the SX in crew-cab with a chassis or ute back in either 4x2 or 4x4 with a 2.2L engine, which is also available in the LSM X-Rider 4x4. 

That one will set you back $59,500, which is still far from the most expensive D-Max around. That’s still the Blade, with a 3.0-litre engine and 4x4 only, but it’s now $80,900.

Back to the 2.2s, and the SX grade comes with the basics. Cloth upholstery, polyurethane steering wheel and gear selector, vinyl flooring and even halogen lights.

There’s basic air-conditioning, but it does have a HEPA filter, and rear vents for crew-cab models, plus there’s wireless Apple CarPlay and Android Auto, auto wipers, and USB-C power ports as well as a USB-A port.

The central multimedia touchscreen is 8.0 inches, but the driver display is a little 4.2-inch unit between physical dials.

Stepping up to the LSM X-Rider brings with it auto-levelling LED headlights and LED daytime running lights, black styling trim, nicer cloth trim upholstery and gloss black 17-inch alloy wheels.

The rest of the D-Max line-up is 3.0-litre-only, and remains as it was before.

The X5 xDrive40i is powered by BMW’s legendary 3.0-litre DOHC 24-valve in-line six with state-of-the-art technology.

This includes twin-scroll turbocharging, variable valve/camshaft timing and 48-volt mild hybrid technology (delivering up to 9.0kW and 200Nm) using an electric motor integrated with the transmission.

The combined effect is optimised power and throttle response (0-100km/h in 5.4 secs) with minimal fuel consumption and Euro 6d emissions.

It produces 280kW between 5200-6250rpm and 520Nm of torque (this can reach 540Nm with hybrid input) across a remarkably wide and flat peak torque band between 1850-5000rpm, which showcases its flexibility. There’s also auto start-stop and selectable drive modes.

This is paired with BMW’s smooth and sharp-shifting eight-speed torque converter automatic, which combines the best characteristics of a dual-clutch and traditional torque converter transmission.

There’s overdrive on the seventh and eighth gears to optimise fuel economy and the choice of rapid manual-shifting using the steering wheel paddles.

Power reaches its wide tyres through the xDrive intelligent all-wheel drive system, which actively varies the engine’s torque distribution between the front and rear wheels to optimise traction at all times.

BMW’s ‘Efficient Dynamics’ also includes brake energy regeneration with recuperation display and many other standard features to enhance driving safety and efficiency.

The new 2.2-litre turbo-diesel four-cylinder comes with 120kW and 400Nm, that’s 10kW and 50Nm more than before. Isuzu also says there’s 60 per cent more torque ready from near-idle at 1000rpm.

An eight-speed auto replaces the six-speed, but the brand has also culled the manual options that remained in the line-up.

As ever, that sends power and torque to a part-time 4WD system capable of 2H, 4H and 4L with a rear diff-lock.

BMW claims combined average (WLTP) fuel consumption of 9.9-8.5L/100km. Our 415km test comprised a mix of suburban and highway driving and when we stopped to refuel the dash display was showing 10.2L/100km which was line-ball with our own 10.6L/100km figure, calculated from fuel bowser and tripmeter readings.

So, based on our figures, you could expect a realistic driving range of around 780km from its 83-litre tank using standard 91-octane petrol.

The biggest advantage for the new drivetrain from Isuzu’s perspective is that it’s more fuel efficient.

The old engine’s 6.9 litres per 100km become 6.6L/100km in the new engine, in part thanks to a new stop-start system. That system is also now on the 3.0-litre engine, where 8.0L per 100km drops to 7.1L.

With its 76L diesel tank capacity, the D-Max should theoretically be able to travel more than 1000km on a single fill, although that comes down to a lot of variables - that 6.6L figure was achieved in almost lab-like conditions.

It’s supremely comfortable, with front bucket seats that offer powered-adjustment of height, reach and backrest angle along with side bolsters that can tighten their grip of your upper torso.

There’s also two-way lumbar support, that adjusts not only how far it pushes your spine forward but also allows that pressure point to be raised or lowered.

Combined with its power-adjustable leather-rimmed steering wheel, it would be hard not to find a comfortable driving position.

Eyelines to all mirrors are good and over-shoulder blind-spots are minimal. Front and rear occupants can talk without raised voices thanks to low engine, wind and tyre noise at highway speeds.

As you’d expect, it has high build quality and a tangibly solid feel as though it was machined from a single block of steel, from the satisfying thuds of its closing doors to the absence of shudders or rattles on a variety of roads.

It also has two personalities, which can be switched in an instant. In 'Comfort' mode it will happily cruise around city and suburbs as a mild-mannered family car, fulfilling daily duties like work commutes, school drop-offs and pick-ups, supermarket shopping and the like.

However, flick the drive mode to 'Sport Plus' and you awaken, well, if not ‘the ultimate driving machine’ then something close.

Its optimised drivetrain and handling settings feel more like a sports sedan than a family car, which can turn any winding mountain road into an engaging experience.

It has impressive reserves of cornering grip and braking force, combined with sparkling engine response and fast sequential manual-shifting at your fingertips.

It feels impressively agile, with all-round response that belies its 2.0-tonne-plus kerb weight, backed by a symphony of sounds from its sublime in-line six.

Let’s start with the most important part of the updated D-Max. The new 2.2L is smooth. 

It feels so much more refined physically, but it's also quieter. Paired with the new eight speed, it makes the D-Max a much more likeable ute than it was with the rattly 1.9L.

At the launch, Isuzu had a bunch of MU-Xs to drive (keep an eye on a review coming soon), and the new drivetrain actually suits that big family SUV down to a tee.

The power and efficiency changes are second to how much it changes the characteristics of the thing.

If anything, the D-Max sits in a slightly higher gear than necessary, probably to try and eke as much out of the diesel dual-cab as possible in terms of fuel efficiency, but put your foot down and a more appropriate gear is close-by, and without much fuss.

There's also a relatively good stop-start system. It's not seamless but it's better than some. You take your foot off the brake and the engine rattles back to life, rather than waiting for you to put your foot back down.

The rest of the D-Max’s behaviour is pretty standard ute stuff, as it was before.

The steering is on the light side, but accurate enough even though it has a slightly doughy spot dead-straight. It’s not anything you wouldn’t expect from a ute.

Similarly, the brakes are a bit spongy but predictable, and once you’re used to where the ‘bite’ point is it’s easy to live with.

The suspension is a bit busy, but easy to keep on top of and doesn’t jostle you around. 

Isuzu has done well to include pretty much the full range of safety features across all its variants, with the SX only missing out on rear parking sensors - it still has a camera though, obviously.

Key features like rear cross-traffic alert with braking and adaptive cruise control are standard, plus the D-Max achieved a five star crash safety rating from ANCAP, even though that was under slightly easier testing back in 2020.

The biggest (but only) gripe on-test with the D-Max’s safety gear was its lane-keep during adaptive cruise. There seemed to be a need for the ute to sit close to either the centre line or shoulder during cornering, which led to some discomfort on fast country roads.

BMW covers the X5 with a five year/unlimited km warranty and offers several service plans to suit different budgets and requirements.

For example, the 'Service Inclusive Basic' package covers all scheduled services over five years/80,000km for a total of $3450, or an average of $690 per year.

Isuzu’s six-year/150,000km warranty covers the D-Max, which could do without the limited distance, especially for a workhorse.

There’s also five years of flat-rate servicing every 12 months or 15,000km, costing $469 each time.

That’s gone up about $20 per visit since the update, with total cost over the five years at $2345.

There are 164 Isuzu dealers across the country, so finding somewhere to service shouldn’t be a challenge.
