Holden Commodore vs Mahindra Scorpio-N

What's the difference?

So will the new Commodore become Australia's favourite car? I strongly doubt it, but it's not the car's fault, and it wouldn't be any different if it was a rear-wheel drive, V8, Australian-built sedan. Australian buying habits have just moved on, and diversified into a range of SUVs, small hatches and dual-cab utes. 

Taken as an all-new entry in Holden's revitalised line-up though, the new Commodore ticks all the important boxes required of a mid-size to large passenger car these days. It may not be anywhere near as exciting as a 6.2-litre Redline sedan, ute or wagon, but it’s objectively a far better car overall, and you should definitely give it a drive before dismissing it. 

The pick of the bunch in my eyes is the $39,490 RS Sportwagon with the 2.0-litre petrol engine. Yep, the best new Commodore is now a four-cylinder station wagon.   

Be sure to check out what James Cleary thought of the new Commodore in prototype guise here:

It might seem like I’ve been harsh on the Scorpio but I actually reckon this vehicle is in fact a step in the right direction for Mahindra.

It’s nice enough to drive on-road – refined and comfortable – and it’s also a capable 4WD, with a few issues though…

It’s a good value-for-money prospect but it’s lacking a lot of driver-assist tech that should be onboard every modern vehicle, especially one that will serve as a family mover.

Aside from the move to a front-drive basis, the other key difference between the new Commodore and those of the past is its shift from a classic three-box sedan shape to a sleek, five-door Liftback. Even the Sportwagon has an elegant arc to its roofline, which is arguably their most appealing design element. There are no Ute or Caprice bodystyles, and there never will be. 

The European-designed look is less macho than the bulging wheelarches of the VE and VF, but more in line with its European rivals like the Ford Mondeo, Volkswagen Passat and Skoda Superb. 

The best way to identify specific models is by their wheels, with the trim levels split between a more elegant body trim on the entry, Calais, Calais-V and Tourer variants, and sportier body kits with side skirts and a rear spoiler on the RS, RS-V and VXR flagship.

The interior look is also best described as elegant, with fresh shapes that flow cohesively into the door trims and centre console. There’s a general air of quality about it, but it’s let down by some cheap-feeling controls and switches, particularly the climate control knobs. 

The ZB’s overall size is bigger than you might think, with most dimensions fitting neatly between the VE/VF and the VT-VZ generation that preceded it. 

You might be surprised to learn it’s no lightweight either, with the heaviest Calais-V Tourer actually outweighing the portliest VF by 31kg. 

Interior dimensions are comparable with its predecessor, with the most significant differences being a narrower back seat thanks to its 36mm thinner body and 13mm less rear headroom in the Liftback (but 3mm more in the wagon).  

Before the decision was made to source the new car from Germany, Holden was planning a longer wheelbase for Australia. One specific requirement that did reach fruition is the availability of a V6 engine, which isn’t fitted to European versions.

Under the skin it rides on GM’s E2XX platform, which is a significant evolution of the chassis that underpinned the previous Insignia and the now-defunct Holden Malibu. 

Aside from having a say in every step of its design process, Holden engineers covered more than 200,000 kilometres of testing on Australian roads and at the Lang Lang proving ground.

This has been to fine tune the drivetrain calibrations, the steering, suspension, and even details like the sat nav and radio reception to suit our tastes and unique demands. 

Specific suspension tunes have been developed for four cylinder models, the V6 Calais, V6 RS-V and the Tourer, with unique setups between Liftback and Sportwagon bodies. 

The only version not to score an Australian suspension tune is the VXR, which was treated to a performance-focused setup at the Nürburgring in Germany. 

The Scorpion reminds me a bit of the early-generation Hyundai Terrcan – long bonnet, generic cabin, and it appears to sit quite low.

The Mahindra SUV has 18-inch alloy wheels, side steps, roof rails and sunroof.

It all looks fine and, anyway, the more interesting stuff on the Scorpion is under the skin – the fact that it is a body-on-frame 4WD.

Another traditional Commodore trait to have taken a step backwards is its ability to carry three adults across the back seat. Admittedly only really an issue for taxi use, the ZB will certainly still swallow three, and likely three child seats, but less comfortably and more like the similarly sized Camry.

The Liftback’s reduced headroom didn’t matter for this 172cm tester, but if you were marginal in a VF you’d probably want to avoid spiking your hair.  

The cabin ticks all the other important boxes for a modern family car, including twin cupholders front and rear, bottleholders in each door and two ISOFIX child seat mounts in the rear. 

All get a good cluster of USB and 12V charge points, while the RS-V models upwards get a big bonus with wireless phone charging. 

The Liftback's boot space is only slightly down on before at 490 litres, but the huge opening created by the five-door design is so much more useful in the real world. It also brings a split-fold back seat for the first time in a non-wagon Commodore. 

The Sportwagon has lost around 100 litres in capacity though, but is still a very useful 560 litres to seat height or 793 litres to the roof. 

Holden’s local team has also developed a range of optional accessories for the Commodore, which includes a bonnet protector, weather shield, towbar, boot liner, floor mats, headlight protectors, sill guards, locking wheel nuts, roof racks and a cargo net, but there’s no sign of a cargo barrier, nudge bar or bullbar at this stage.

The cabin is tidy and functional. The 8.0-inch touchscreen multimedia system is easy enough to operate without strife and the screen is clear, although it’d be great if it was bigger.

The tan synthetic leather interior trim looks good and superficially the whole interior looks nice, but if you inspect a little more closely the Scorpio’s cabin is missing the storage spaces, USB charge points and build quality of rival SUVs.

There’s one cupholder (between driver and front passenger), the door pockets are narrow and there are few other storage spaces.

With the third-row seats in use, there’s a very small rear cargo area, and those seats don’t fold flat so when they’re not in use they seriously impact the storage space.

As a result, the Scorpio is one of the few modern 4WDs that I’d consider taking out the third row every time long-distance loaded-up travel was on the cards – just so it’s a more practical touring vehicle.

Some features, such as the directional air vents, feel flimsy. Otherwise, the Scorpio’s cabin is suitably practical, rather than overly impressive.

The Scorpio is available in two grades: the Z8 with a drive-away price of $41,990 (at time of writing) and the Z8L at $45,990 drive-away (at time of writing), which we tested.

Standard features in the Z8L include an 8.0-inch touchscreen multimedia system (with wireless Apple CarPlay & Android Auto), wireless phone charger, a 12-speaker Sony stereo, dual-zone climate control, front camera (intended for off-road use), front and rear parking sensors, and a six-way power-adjustable driver’s seat.

It has a leather wrapped steering wheel and gearshifter, tan- and 'rich coffee'-coloured synthetic leather interior trim, a cooled glove box, sunroof, and six-seat layout (with two captain's chairs in the second row).

It has 18-inch alloy wheels, automatic wipers and projector LED headlights, push-button start, keyless entry and a tyre pressure monitoring system.

Our test vehicle also had floor mats ($200) and side steps (approximately $1250 fitted) as the only accessories.

Exterior paint choices include 'Deep Forest', 'Everest White', 'Napoli Black' (on our test vehicle), Dazzling Silver' and 'Red Rage'.

No, there’s no more V8, manual transmission or rear wheel drive, but the ZB’s options are more in sync with its newer rivals. 

For the first time since the VH, or 1984, the base engine is a four-cylinder petrol unit, but uses modern tech like direct injection and a turbo to boost power statistics to more than triple that of the infamous Starfire engine. Also seen in the Equinox, the new turbo motor’s 191kW is also notably 6kW more than the 5.0-litre V8 in the VL Group A SS (Walkinshaw), and 1kW more than the 3.6-litre V6 was making in top-spec VZ Commodores – so pretty good horsepower for its engine size.

MORE: If any Commodore engine problems or automatic transmission problems crop up, you’ll likely find them here.

The real story is its healthy 350Nm of torque, which is also more than what the same VZs were making, but on tap from a useful 3000-4000rpm.

The latest version of the 3.6-litre Alloytec V6 that’s seen duty in VZ, VE and VF models makes a reappearance as the new performance leader, but mounted sideways and turning all four wheels this time. In ZB trim, it produces 235kW and 381Nm, the latter from 5200rpm.

For the first time, you can also choose a diesel option with LT and Calais trims, which is a version of the engine used in the previous Opel Insignia. You’ll also find it under the bonnet of the Jeep Cherokee and Compass, and its applications spread as wide as the Alfa Romeo 159 that ended production in 2011. In Commodore guise, the turbo 2.0-litre engine specs are 125kW and 400Nm (available from 1750-2500rpm), and therefore taking out the torque trophy for the ZB range. 

Both petrol engines are paired with a nine-speed torque converter automatic transmission, while the diesel has an eight-speed gearbox. Both four-cylinder engines are front-wheel drive, while all V6 variants are all-wheel drive. 

MORE: What’s the difference between 4X4, 4WD and AWD

The all-wheel drive system is actually quite clever, using what’s called a Twinster twin-clutch rear differential for finite torque vectoring, or sending the just the right amount of power to each wheel. The system varies torque distribution between 100 per cent front and a 50/50 split. 

If you think the Commodore has gone soft, its towing capacity ratings also suggest otherwise, with a 2100kg maximum braked rating for V6 models matching the best offered previously. The four cylinder models are rated at 1800kg, which is 200kg better than what the previous 3.0-litre V6 and LPG models carried.

The Scorpio has 2.2-litre four-cylinder turbo-diesel engine, which produces 129kW at 3500rpm and 400Nm at 1750-2750rpm.

It has a six-speed automatic transmission, an auto-locking rear diff, and a part-time 4WD system with a dual-range transfer case incorporating low range.

Note: the Scorpio must be in neutral and stationary for the driver to shift into 4WD low-range, but the driver is able to shift between 2WD and 4WD High on the move, up to 80km/h.

Its '4Explor' system’s drive modes include 'Normal' (2WD for sealed surfaces), 'Grass/Snow' (4WD), 'Mud & Ruts' (4WD), and 'Sand' (4WD).

As you’d hope, the ZB sets a new Commodore benchmark for fuel consumption, with the diesel models managing a best official combined figure of 5.6L/100km. The petrol four-cylinder models also pip the VF’s best combined fuel economy figure of 8.3L/100km with 7.4 and 7.6L/100km for the LT, RS and Calais Liftbacks respectively. The Sportwagon versions wear 7.7 and 7.9L/100km figures, while V6 versions span 8.9-9.3L/100km combined ratings. 

It’s worth noting that the petrol four-cylinder engine needs premium 95RON unleaded to do its best, while the V6 is happy to run on regular 91RON unleaded. All versions have a 61.7-litre fuel tank. 

Official fuel use is listed as 7.2L/100km on a combined cycle.

Fuel consumption on this test was 9.6L/100km, which is impressive, especially in light of the fact that we spent the lion’s share of two days during the test period in 4WD low-range.

It has a 57-litre fuel tank, so, going by those fuel figures, you could reasonably expect a driving range of about 593km out of a full tank. 

Note: That 593km is a best-case scenario figure and has not had a 30-50km safe-distance buffer subtracted from it, and it also does not take into account the fact that, when being used for touring, the vehicle will be loaded with people, pets, camping gear and more.

The Commodore we know and most of us love is just as famous for its quality driving experience as its local production and motorsport successes. So, the ZB has some big shoes to fill in this area. 

At the ZB’s media launch, we drove everything aside from the base LT or any diesel variant, over several hundred kilometres of pretty much every road condition. 

I’ll cut to the chase. There’s a genuine quality to the way they handle Australian road conditions. We drove them back to back with a UK-spec model at Lang Lang, and while you’d expect the local car to excel at its own test facility, the rear and front suspension work in harmony to handle mid-corner bumps with far greater stability than the alternative. The electric power steering weighting was also lighter, but it didn’t seem to lose any precision. 

You probably wouldn’t notice it driving to the shops every day or cruising on the highway, but this on-limit controllability could easily be the difference between life and death in an emergency. 

The turbo four is a surprisingly capable and refined package, and would honestly be my pick if I were in the market. It’s smoother and more tractable than the V6, so feels like it would deliver speed more readily than the bigger engine unless you were going flat out. 

Holden isn’t quoting official 0-100km/h acceleration figures, but we hear the petrol four is good for a 7.0 second-ish time, and the V6 will manage just over 6.0sec. So there’s really not much in it outright. 

Therefore it’s a shame you can’t get the Tourer with the petrol four, but because the combination is available in Europe, Holden could shift the line-up if there’s enough demand. 

The nine-speed auto does a pretty good job with either engine, and its electronic brain does a slick job of seamlessly adjusting its shift behaviour to your driving style. 

Holden isn’t quoting ground clearance figures, but all have enough to handle dirt roads, and while the 17-inch wheel equipped models match the VF II’s 11.4m turning circle, be aware that the 18-inch wheel variants blow out to 11.7m, the 19s are 12.7m, and Holden doesn’t quote a figure for the 20-inch equipped Calais-V Liftback and VXR.   

The only other surprise among the group we drove is the Calais-V Liftback, which is likely to be a bit too sharp in its ride for some luxury buyers on its big 20-inch alloy wheels. The Calais or one of the Tourers would be your best bet for comfort.  

The VXR performance flagship is a completely different personality to the SS models of the past. It’s nowhere near as fast, but is more of a grownup package that’s easier to get the best out of. 

Its more demure than the brash final VF IIs, and the V6 does make a pretty sweet note, even if half of it is coming from the speakers.

Nothing was ever going to replicate the romance and pride of the last SS, but all is not lost for fans of fast Holdens.

The Scorpio is a 4WD with a body-on-frame chassis. For those of you who don’t know (no shame in that) a body-on-frame chassis denotes a chassis onto which the vehicle’s separate body is attached, and the engine, wheels, and suspension are fitted.

The set-up is well suited to towing and/or carrying heavy loads, and 4WDing.

It’s 4662mm long (with a 2750mm wheelbase), 1917mm wide and 1857mm high. It has a listed kerb weight of 2100kg and a 12.6m turning circle.

Right, that’s enough (boring?) measurements for now.

This Mahindra 4WD is surprisingly refined on-road: quiet inside, comfortable and with a no-stress engine and a low-key workmanlike Aisin-sourced auto delivering a relaxed, almost lethargic combination on the road.

Steering has a nice weight to it, ride quality is okay, erring on the side of spongy rather than too firm, and some body roll creeps in on more energetic bends.

Overall, however, the Scorpio does satisfactorily well on sealed surfaces. But how does it perform off-road?

The Scorpio handled the undulating dirt track leading to our off-road test site with ease, riding nicely over the light to medium corrugations, and was only ever minimally unsettled by the bumpy terrain.

This Mahindra is able to be shifted between 2WD and high-range 4WD (4H on the dial) so you can keep moving even when the road/track surface changes all of sudden.

The Scorpio has plenty of old-school foundational 4WD mechanicals onboard – low-range and a rear diff-lock (albeit an automatic one) – and it also benefits from off-roading-oriented tech such as its 4Explor system with selectable terrain modes, each of which adjusts engine output, transmission settings and traction control to best suit the terrain, conditions and driving style. 

It also has hill descent control and hill hold control.

Even its forward-facing camera comes in handy. I still think of these as more a novelty – I prefer to get out and check the track ahead or get a spotter to do the work for me – but I can see the inherent value of this tech in helping the driver to maintain vision, especially if forward visibility is compromised, say for instance up and over the crest of a steep rocky hill, or edging towards a steep drop into a creek bed.

While the Scorpio’s 400Nm may seem a bit lowly, that torque is on tap across a good spread of revs, and this 4WD does well with what it has. The engine keeps everything moving along nicely.

In terms of off-road-relevant measures, the Scorpio has 227mm of ground clearance, a guesstimated wading depth of 500mm or so (it’s not listed), and approach, departure and ramp-over angles of 27.2 (good), 21.3 (not so good), and 23.5 (okay) degrees, respectively.

The Scorpio is quite an effective off-road wagon and it tackled every obstacle it faced without fail, but it has to be driven with extreme care and laser-focused concentration.

No harm in that, I hear you cry. In response, I say, sure, but it’s bloody exhausting work having to nurse a vehicle through even innocuous terrain in order to avoid nudges, bumps and scrapes to its underbody and side steps.

Not to mention how tiring it is having to anticipate if/when off-road traction control and/or the auto diff-lock will engage – or not – at crucial moments.

Not a major concern on flat ground, but think about the auto rear diff-lock cutting out on you while driving up a rocky 32-degree hill. Yep, I’m old.

Now for some more of the Scorpio’s less-than-ideal characteristics.

1. I hinted at this in the previous paragraph: off-road traction control doesn’t seem as well calibrated as it should be. It’s a bit patchy in its application, and certainly not as seamless as the tech in something like the GWM Tank 300 (yes, I know – the Tank costs about $15,000 more.)

2. The automatic rear diff lock is on the wrong side of clunky, abruptly engaging as it senses wheel-spin then disengaging just as abruptly when it deems the problem over ... even if it isn’t quite over yet.

3. The Scorpio feels low: a lot of underbody components are vulnerable to rocks, tree stumps, track debris, and the AdBlue tank sits low behind the rear left-hand wheel.

4. The side-steps seem very flimsy. The right-hand side-step took a soft knock going over an exposed tree root early on one test day, which I thought nothing of. But when I looked at it soon afterwards, the fasteners had popped out at the front and middle of the sidestep.

I didn't think the bump had been anywhere near enough to result in that.

5. The Scorpio’s standard tyres – MRF Wanderer SUV tyres (255/60R18 “All-Season”) – are not great for hard 4WDing.

They don’t offer anywhere near the degree of grip you need in difficult 4WDing and they quickly became gummed up with mud. The Scorpio does have an underslung full-size steel wheel spare.

The Mahindra Scorpio Z8L has a listed payload of 510kg, and can legally tow 750kg (unbraked), and 2500kg (braked). Gross vehicle mass (GVM) is a listed 2610kg; gross combined mass (GCM) is 5155kg.

I experienced a bit of an issue on a drive home after a few hours of tough 4WDing: 4H kept trying to engage during a 100km stretch of highway.

A dot kept flashing above 4H near the shifter, and terrain modes (other than Normal) kept flashing on the centre console and driver info display and I was being prompted to drop below 80km/h to shift into 4H.

Of course, I’d earlier switched from 4H to 2WD at the end of our filming day (at the 4WD location) and made sure I'd engaged Normal mode before I left the dirt and drove onto a sealed surface.

When the 4H-related issues kept happening on the highway I was able to fix the problem by stopping, switching the Scorpio off and back on again – but I had to do this every 5.0km or so four times before it finally sorted itself out.

To Mahindra’s credit, technical staff members are looking into the issue.

The Mahindra Scorpio Z8L does not have an ANCAP rating because it has not been tested.

As standard, it has six airbags (front, front side and curtain), electronic stability control, front and rear parking sensors, a tyre pressure monitoring system, as well as trailer sway and roll over mitigation, hill hold control and hill descent control.

It lacks a lot of driver-assist safety tech that’s onboard a lot of other vehicles at this price-point, and even cheaper.

Holden is currently offering a seven-year, unlimited kilometre warranty with roadside assistance to help boost sales, but be on the lookout for the return of this deal if you miss out this time. Normally, the Commodore carries the standard three year/100,000km warranty. 

Service intervals are now 12month/12,000km, which have shifted from the previous 9month/15,000km terms.

Service costs are capped for the first seven trips to the workshop, with petrol models costing $259, $299, $259, $359, $359, $359 and $259, or a total of $2153 over seven years or 84,000km. The diesel is actually slightly better value at $259, $359, $259, $399, $359 and $399, or $2134 over the same period.

The Mahindra Scorpio Z8L has a seven-year/150,000km warranty.

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