Mitsubishi ASX vs BYD Sealion 5

What's the difference?

There is no question the new ASX is a much better car to drive than the model it replaces. This one is actually fun behind the wheel. The tech represents a massive upgrade, so too does the interior design and practicality. The fact is, it’s a much more expensive car than the old ASX. It is a European built and designed small SUV with loads more tech and features so when you consider that, the pricing makes more sense.

Regardless of the previous model, this new ASX impresses. It’s not perfect - the LS is missing too many items, no hybrid, slightly firm ride - but it’s now a genuine rival for higher quality rivals in the small SUV segment. If the ASX is in your price bracket, it might be time to add it to the consideration list.

While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.

BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.

The look of the new ASX is not a huge surprise given it’s based on the second-generation Renault Captur that launched in 2021. Actually the ASX we get is the mid-life facelift for the ASX/Captur twins in Europe, so the design has been refreshed.

At 4238mm long, 1797mm wide, 1585mm tall and with a 2639mm wheelbase, the new ASX is 127mm shorter, 13mm narrower, and 55mm lower than the original, but the wheelbase is only 31mm shorter.

It has a round almost bubble like quality to the exterior design, and not in a bad way. The redesigned front end has Mitsubishi flavour thanks to the ‘Dynamic Shield’ front-end signature, while the sleek headlights and black and chrome grille give off an almost menacing look.

C-shaped tail-lights at the rear flank a massive ‘Mitsubishi’ badge and the lower cladding ensure there’s no doubt this is an SUV.

It’s a handsome car and should get some attention on the road.

Inside, it’s not the last word on interior design, but it’s well laid out and functional. It’s definitely another massive leap over the old model.

At the launch there were no LS grades to drive, but the Aspire comes with cool grey cloth trim and roofliner that adds a nice contrast to the darker plastics and finishes. It’s more vibrant than the top-spec Exceed which has an all-black interior with leather-appointed seats.

The top two grades feature a floating console where the gear shifter is housed (a standard shifter in LS, and notch-like ‘eShifter’ in Aspire and Exceed), while the big multimedia screen dominates the dash.

The BYD Sealion 5, from the outside, is inoffensive but also uninspiring. That’s likely not such a bad thing for a mid-size SUV – it’s rare you’re hearing someone talk about how beautiful the Mazda CX-5 or Toyota RAV4 is. 

Its quartet of colour palette options comes in on the safe side, too. Aurora White is standard, Atlantis Grey, Harbour Grey and Cosmos Black are cost-options.

Our test car is Atlantis Grey, which is interestingly quite blue. 

The relatively upright shape is a slight departure from the more ‘aquatic’ silhouettes of BYD’s line-up, but the front grille and light layout are decidedly in step with the brand’s oceanic design language. There’s a bit going on, you could say.

The slimline tail-lights are the rear, especially from a three-quarter angle to the side, look attractive and help break up the rear without looking messy.

The Sealion 5’s design is overall net-good, but it’s inside where the mid-sizer feels like you’re getting plenty for your dollar.

The seats, despite the leather fakery, feel like decent material, and the layout uses buttons and physical controls cleverly without feeling outdated.

This is an area the ASX excels in.

Up front there are loads of storage options. Multiple nooks for mobile phones, keys and other items, and the Aspire and Exceed get a wireless charging pad and extra storage under the shifter.

The central bin isn’t massive but doesn’t need to be with all the other cubbies, and there is ample room for large and tall bottles in the door bins.

A pair of USB-C ports and a 12V port up front handle electronics.

Thankfully there are physical controls for climate control at the base of the multimedia screen. The other functions housed in the screen like vehicle information and connectivity options are logically laid out and the system is not overly complicated.

Opting for the Aspire or Exceed means you get the brilliant Google Built-in, which is exactly what it sounds like. It’s essentially the Google operating system but for your multimedia screen so you have in-built Google Maps, Play and Assistant. Log in to your Google account and all your favourite places show up on Maps, and you can also log into Spotify and the like. It's a great set-up.

The seats are supportive and well bolstered. Much nicer than the old ASX’s overly cushioned seats.

The second row has more space than you’d expect looking at the car. It’s not cavernous by any stretch, but clever touches like scalloped out front seatbacks and roofliner ensure decent leg, toe and headroom, even with the sunroof in the Exceed. However, three adults in the rear isn’t super comfortable - we tried. Kids should be fine.

Amenities include more USB-C ports, rear air vents (very rare in this category), storage for small bottles in the door, phone holders in the door arm rests, dual map pockets, but no central armrest, which is no great loss.

That rear pew is comfy and more supportive than the old ASX. And it has a neat party trick. You can slide the entire row (via the base) forwards by up to 16cm, making for more cargo space in the boot. It also folds 60/40 split and when the boot floor is in its highest setting the seats fold flat, aiding loading.

Yet another clever feature is the split level boot. It features under-floor storage that adds a handy 183 litres to the cargo capacity.

With all seats in place Mitsubishi says the cargo space is 484 litres, which is 23 per cent more than the old model. If you slide the rear seat forward as far as it goes that increases that figure to 616L. And if the second row is folded flat the capacity is 1596L.

Interestingly, despite having space for one under the bottom boot floor, a spare wheel (even a temporary one) is not a standard feature. Instead the ASX comes with a tyre repair kit and offers a temporary spare wheel as part of its accessories offering for $750. If you’ve got the space for a spare wheel, why not make it standard? Especially when Mitsubishi is a popular brand in regional and rural areas.

To actually interact with the interior is, at times, another story. BYD’s tech interface is generally easy to manage, but could be simpler when it comes to navigating menus for the sake of driver distraction.

While larger text and buttons would be welcome, the multimedia system is easy to use when parked, and the functionality is impressive for the price point.

Winning more points for the Sealion 5, though, are the physical controls – buttons and the traditional gear selector – which make the cockpit much more intuitive while on the move.

Ergonomically, though, the adjustment between the steering wheel and driver’s seat could do with some work, as I found it difficult to find a truly comfortable driving position. This is coming from someone 178cm tall, a very normal height in Australia.

Better adjustability on the steering column would be helpful, as it’s something I’m not sure I’d ever get totally used to.

Visibility and physical space inside the Sealion 5 is impressive, though. The car is 4738mm long, 1869mm wide and 1710mm tall, and the roof and window lines don’t swoop too aggressively towards the rear.

There are low window shoulders even into the rear, so light isn’t at a premium, though under-leg support could be better on the pew.

It’s otherwise un-cramped. The 2712mm wheelbase means decent legroom for second-row folk, plus behind the 60/40 split-fold seats there’s 463 litres of space for luggage. That becomes 1410L with the seats folded.

There’s unfortunately no spare tyre, just a tyre repair kit.

The BYD Sealion 5 Essential kicks off from $33,990 before on-road costs, four big ones less than the Premium ($37,990). We’re focusing on the Essential today, but don’t think that means a shallow list of features.

As you’d expect from BYD if you’ve been paying attention to the Chinese brand in its emergent years, the Sealion 5 comes with more than $34K would normally get you – a 10.1-inch central multimedia touchscreen, an 8.8-inch driver display, synthetic leather upholstery, dual-zone climate, a six-speaker sound system, wireless Android Auto and Apple CarPlay, USB-A and -C ports front and rear, digital radio and keyless entry.

On the outside, LED headlights and tail-lights are the same for both variants.

Both also have 18-inch wheels, not unwelcome for the benefits of on-road comfort.

Consider that the most popular SUV in the country, the Toyota RAV4, costs at least $45,990 without the benefit of a plug-in drivetrain (yet) and comes with, on paper, a more sparse list of features.

The closest PHEV competitors are still more pricey, including the Geely Starray ($37,490) and Chery Tiggo 7 ($39,990), and arguably lack the brand power BYD has come to enjoy.

For now, all grades of the new ASX use the same 1.3-litre four-cylinder turbocharged petrol engine offering up 113kW of power and 270Nm of torque. That’s up on the old 2.0-litre naturally aspirated unit’s 110kW/197Nm.

This is paired with a seven-speed dual-clutch transmission driving the front wheels only, so there’s no all-wheel-drive version.

Mitsubishi is looking into the mild hybrid and full hybrid versions that are offered in Europe but not confirmation on those as yet.

The Sealion 5’s front wheels are driven by a combined maximum of 156kW thanks to a 1.5-litre four-cylinder petrol engine (145kW/300Nm) and a permanent magnet synchronous motor (72kW/122Nm).

BYD claims a 0-100km/h sprint of 7.7 seconds for the Sealion 5 Essential, four tenths faster than the Premium despite only a 61kg difference in kerb weight.

The new ASX consumes 6.4 litres of fuel per 100 kilometres on the combined cycle and emits 142 grams per kilometre of CO2.

That’s a decent figure for sure, but not quite as frugal as the 1.3-litre Nissan Qashqai, which manages 5.8-6.1L/100km.

The ASX drinks 91 RON fuel and has a 48-litre tank which makes for a theoretical driving range of about 750km.

With a charged 12.9kWh lithium iron phosphate (LFP) battery and a full 52-litre (95 RON minimum) fuel tank, BYD reckons the Sealion 5 Essential can cover 1001km under NEDC testing, which is optimistic. It claims 71km can be done on EV power alone.

Not only due to the lenient nature of NEDC testing (WLTP is more common and usually results in lower ranges), but the reality is that once the battery is flat, the engine is doing a lot more work.

Charging is slow, limited to 3.3kW (AC only), which should take between 4 and 5 hours to charge from the lower end of the gauge for the battery size. Given most PHEV owners will do this overnight at home, that’s certainly not the end of the world.

Claimed consumption figures are 1.2L/100km with more than 25 per cent battery charge, or 4.5L/100km when it dips below that.

Realistically you could do sub-50km trips and use no fuel, or never plug your Sealion 5 in and see fuel consumption soar. In any case, anything close to 1001km in a single run is extremely unlikely.

Look, it’s fair to say the original ASX was not a driver’s car. Reliable? Yes. Spacious? Absolutely. Great value? You bet. But fun to drive? Not so much.

So it’s good news then that the new-gen ASX is much more engaging to drive. I quite enjoyed the current-gen Renault Captur the last time I drove it, and the underpinnings of the ASX are the facelifted version of that Captur.

The 1.3-litre turbo-petrol unit might not be ultra quick off the mark, but it is sprightly and really comes alive when you’re at speed. It also has a decent engine note.

I've recently driven another Renault model with basically the same powertrain but it suffered from dreadful lag - a combination of a turbocharger and a dual-clutch transmission.

I had expected the same of the ASX, but there’s little lag to speak of. And the transmission is much smoother in this application. It doesn’t hold gears or do anything DCTs are known for, which is a lovely surprise.

Steering is sharp enough and the feel can be adjusted in the settings. Aspire and Exceed grades come with Comfort, Sport and Perso mode, which is for personalisation.

Ride quality is fine on smooth roads but big pot holes and other bumps are felt in the cabin. It is a European car, so no surprise that it’s been tuned for a more European experience. It’s not so firm it’ll dampen the drive experience, but it could be a touch more supple.

On that, the ASX has not undergone a local ride and handling tuning program like the one its larger Outlander stablemate has benefited from.

That doesn’t mean you can’t have fun in the ASX - you can. It handles high-speed bends on country roads surprisingly well, with more grip than you’d expect. There’s a little body roll but nothing dramatic.

More time behind the wheel is needed, but the tight chassis means the ASX likes a corner.

The cabin has better insulation than the outgoing model but it’s still not the most hushed small SUV money can buy. But it’s another element that’s far from a dealbreaker.

You might expect a car at this price, regardless of its drivetrain, to be underwhelming from behind the wheel.

That, then, makes it even more pleasantly surprising that the BYD Sealion 5 is actually rather competent. Not massively exciting or dynamic, but certainly not a disappointment.

The Sealion 5 is, save for a couple of arguably minor annoyances, quite easy to get used to and drive.

Firstly, when making proper use of its electric power, the drivetrain provides enough shove for its intended use. It’s not overly powerful, but you won’t have trouble overtaking. It’s the same with most of the inputs, the steering is light but not completely numb – again about right for how the Sealion 5 will be driven.

Perhaps its biggest departure from expectations based on other cars from China is its suspension is on the stiffer side of things, but again it’s not unruly or too rugged. In fact, it does provide a better sense of control than many of its compatriots.

Again, the biggest issue with the Sealion 5 day-to-day is its driving position, the steering column adjustment isn’t up to scratch and there’s not really a perfectly comfortable seating position (I’m a very standard 178cm).

On long trips, you might also find the engine gets quite noisy once the battery power is gone as it works hard to pull the mid-size SUV along under acceleration.

Its driver-assist systems are, you might be pleased to hear, on the calmer side of things – BYD is getting better at calibrating its safety features and I didn’t find myself rushing to switch it all off as quickly as usual.

It can still be a bit too persistent in its lane-keeping, but it’s a big improvement on the way things were.

There’s no ANCAP rating for the Sealion 5, but the list of safety kit isn’t lacking on paper.

BYD lists seven airbags ,including full-length side-curtain bags and an important centre airbag, plus there’s a whole suite of tech that’s, as noted, better behaved than past driver-assist systems from BYD.

The Essential only misses out on a surround-view parking camera and front parking sensors, both arguably important safety features for parents, but the rest of the list is the same as the Premium including adaptive cruise control, lane-keep and lane departure assist, traffic sign recognition, blind-spot monitoring, rear cross-traffic alert with rear AEB (as well as front AEB, of course) and tyre pressure monitoring.

Mitsubishi's standard warranty is five years or 100,000km, but if you service your car exclusively at a Mitsubishi dealer, it extends to an impressive 10 years or 200,000km.

You’ll also get 10 years of roadside assistance and capped-price servicing. The servicing schedule is every 12 months or 15,000km.

Service pricing starts from $349, but bigger services every four years or 60,000km will cost circa-$1000. The average price of a service across the 10 years is $568, or the total overall is $5686.

Mitsubishi has an extensive network of 185 dealers across Australia and many in regional areas. So service coverage is among the best in the country.

BYD has a six-year/150,000km warranty, which is probably more than you’d need in terms of distance but is behind many competitor brands’ timelines – seven to 10 years is becoming the norm, even if it’s conditional.

An eight-year/160,000km warranty covers the battery, which is about par for the industry.

Servicing for the first five proper services ranges from between $285 and $930, plus there's a free check-up six months into ownership and a total cost over the span of $2355 – an average of $471 per service.

BYD has just over 100 dealerships in Australia, so finding one for servicing shouldn’t be too challenging.
