Cupra Leon vs BYD Sealion 6

What's the difference?

There's a lot to like about the updated Leon line-up, but probably not by lots of people. It won't be a best-seller, Cupra doesn't need or even want it to be. What it will do is offer something different, and in the case of the Sportstourer something very rare.

The S and VZx will face stiffer competition in the hatchback markets, primarily from Volkswagen, Audi and even Skoda, and it's hard to pick an area where they really stand out from the competition, apart from the unique styling. Not that they aren't pleasant cars to drive, it's just a crowded market.

Which is why the Sportstourer, especially with its plug-in hybrid powertrain, has a chance to be something that really sets Cupra apart from its rivals. Dynamic, efficient and different, it won’t fit in - and that’s exactly what the brand is hoping for.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

Design is a key tenet of Cupra’s ethos, because while it may share Volkswagen mechanical DNA, the Spanish brand wants to really stand apart when you look at or sit inside the Leon.

While it may be the same size as a VW Golf, it certainly doesn’t look or feel like one. Yes, there’s the typical Volkswagen build quality to the fit and finishes, but overall it has a unique Spanish style to it.

On the exterior, Cupra has given the Leon a major visual overhaul with the front end featuring a new-look grille, bumper and headlights. At the rear the tail-lights have been redesigned and now incorporate the logo into a single horizontal light bar that runs the width of the rear.

Inside there’s some new materials, but the most notable change is the introduction of a 12.9-inch multimedia screen. Ambient lightning available on all three models helps to highlight the cabin design.

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.

While we’re talking about two different bodystyles here - hatch and wagon - the front seats are the same. So you are treated to Cupra’s stylish but thoughtful layout, which looks nice but also has good practicality.

The seats themselves are comfortable, even after extended periods behind the wheel, while there’s cupholders, sizeable door pockets, a lidded centre console box and a wireless smartphone charging pad.

The previously mentioned 12.9-inch multimedia screen dominates the centre console, sitting proudly at the top of the fascia. Unfortunately, Cupra (like Volkswagen) has fallen to the modern trend of ‘touch controls’ rather than physical buttons.

Not to sound like an old man yelling at clouds, but these touch-sensitive sliders are simply not as user-friendly, especially in a moving vehicle, as a traditional physical button or dial. While the multimedia system is easy to use, especially with Android Auto or Apple CarPlay fully integrated, adding dials for the stereo (on/off and volume) and the climate control would have been great.

Otherwise, the 12-speaker Sennheiser sound system with subwoofer and 390W amplifier sounds great, offering a premium in-car entertainment experience to match the Cupra’s price and positioning.

As for space in the back, which is obviously where the hatch and Sportstourer vary. There isn’t a lot to split them in terms of passenger space. These are both small cars, so neither offer the kind of room you’d get from an equivalent-sized SUV. The real difference is the cargo capacity, the hatch pair offer 344L (or 888L with the rear seats down) whereas the Sportstourer has a more generous 470L/1045L.

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.

Price is key to BYD’s success in Australia. Quite simply, the Chinese brand has undercut its rivals and consumers have responded to that, unsurprisingly in these tough economic times. The Sealion 6 follows the same path blazed by the Atto 3, Dolphin and Seal, offering plenty of vehicle for your money.

BYD Australia has kept it really simple, offering just two models - Dynamic and Premium - with very similar specification and separated primarily by powertrains.

The Dynamic is a less powerful, two-wheel drive option, while the Premium gets more grunt and all-wheel drive; but we’ll detail that later.

Both the Dynamic and Premium come with 19-inch alloy wheels, power-operated tailgate, a panoramic sunroof, powered front seats that are heated and cooled, a 15.6-inch touchscreen, Infinity premium audio, two wireless phone chargers and wireless Apple CarPlay and Android Auto.

The only non-powertrain difference between Dynamic and Premium is a head-up display on the latter model.

One noticeable absence from the Sealion though is a spare tyre. There’s not even a space-saver, just a tyre repair kit, which is disappointing and out of touch with the unique demands of the Australian market.

The Dynamic is priced from $48,990 (all prices exclude on-road costs), while the Premium starts at $51,990.

To put that into context with its competition, the Toyota RAV4 Hybrid range begins at $42,250 for the GX and stretches to $51,410 for the range-topping $51,410.

While, if you’re looking at an electric alternative, the Tesla Model Y currently starts at $55,900. The most direct rival, however, is the Mitsubishi Outlander PHEV which is only available with all-wheel drive and stretches from $57,290 to $73,790 across five variants.

The three Leon models all feature a different powertrain, as each is targeting a distinctly different buyer.

The Leon S is powered by a 110kW/250Nm 1.5-litre turbocharged petrol engine with mild-hybrid assistance. 

The Leon VZx gets a more potent 2.0-litre four-cylinder turbo-petrol engine that makes 221kW/400Nm, to put it right at the heart of the hot hatch market.

The Leon VZe Sportstourer manages to combine efficiency with performance, with a 1.5-litre turbo-petrol engine paired to an electric motor to make an efficient 200kW and 400Nm.

The one thing all three have in common is a seven-speed dual-clutch transmission and front-wheel drive.

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.

Naturally, the three different powertrains provide three very different fuel economy numbers.

The mild-hybrid system in the Leon S allows it to use just 5.4L/100km, which provides a theoretical range of up to 833km thanks to its 45-litre fuel tank.

The VZx is the thirstiest member of the range, not surprisingly, using 7.6L/100km. With its 50-litres tank it has a theoretical driving range of approximately 650km.

Finally, the Sportstourer VZe manages a claimed 0.4L/100km on paper, thanks to its 20kWh battery providing up to 121km of electric-only driving range. Obviously achieving that claimed figure in the real world is incredibly difficult (as it is with any PHEV) but we still managed to use just 2.4L/100km on our mostly extra-urban test drive, which is still a good return.

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.

Obviously there are three very different variants in the Leon range, with three different powertrains and two different body styles, and yet there is a familiar feeling between all three when you’re behind the wheel.

This is arguably the ‘most Volkswagen-y’ element of the Cupras, with the solid, stable Volkswagen underpinnings coming through. This is, of course, not a criticism, but rather highlights the positive connections between Cupra and its parent company, which has allowed it to make an immediate impression on the Australian market.

However, it also means the Leons feel so familiar that they don’t leave you with a unique impression and driving character.

For example, the VZx is almost too good, too quick and too clinical. It lacks the excitement and engagement rival hot hatches offer, notably the Hyundai i30 N and Honda Civic Type R, but instead compensates by just being really capable.

Obviously, that may not be seen as a negative by everyone and for those who want that sort of engaging, dare I say ‘fun and edgy’, driving experience the Leon VZx may not be precisely what they are looking for. Still, the engine is potent and even the lack of all-wheel drive doesn’t dampen its performance abilities too significantly compared to the likes of a VW Golf R or Audi S3.

The Leon S offers a different proposition, a warmed up hatch, rather than something hot. On that front it delivers, providing a well-mannered drive but without the punch of the VZx.

The Sportstourer is arguably the pick of the range, with its combination of sharp driving dynamics and very efficient powertrain. At no point do you feel like Cupra compromised its sporty intent to make the Sportstourer save fuel. Instead, the PHEV powertrain offers plenty of performance when you need it but is otherwise quiet and efficient the rest of the time, helping it to sip fuel at a much lower rate than its Leon hatchback alternatives.

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. 

Both Sealion 6 variants come equipped with autonomous emergency braking, front and rear cross-traffic alert/braking, 'Forward Collision Warning', 'Rear Collision Warning', lane departure warning/prevention, blind-spot detection, traffic-sign recognition, door-opening warning, trailer stability control, auto high beam, a 360-degree monitor, adaptive cruise control as well as front and rear parking sensors. Plus, it can even detect if you’ve left a child or pet inside the car.

ANCAP had not crash-tested the Sealion 6 at the time of publication, but with its comprehensive list of safety items it should tick most of the boxes when it comes to protecting its occupants and pedestrians.

All three Leons are covered by Cupra Australia’s standard warranty, which covers the first five-years/unlimited kilometres. Which is good, especially for a new and more premium brand, even if it’s obviously short of the best-in-market.

Servicing is required every 12 months/15,000km, whichever comes first, and Cupra is offering a servicing pack special until the end of 2025, of $1990 for five years. That works out to an average of $398 per year.

Cupra is expanding its dealer network in Australia too. The Leon drive event we attended began at the newly-opened Cupra Macarther in Sydney’s growing west. There’s also a new dealership at Melbourne’s Essendon Fields.

Of course, one of the key advantages that Cupra has over many other new brands to Australia is its Volkswagen/Audi connections, which allows its models to be serviced at those dealerships as well. That provides a much larger footprint for customers to find somewhere convenient to service their car, which cannot be underestimated.

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.
