BYD Sealion 6 vs Mahindra Scorpio-N

What's the difference?

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

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.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

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.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

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'.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

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).

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

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.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

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.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.

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

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