BMW 128TI vs BYD Sealion 8

What's the difference?

It might not be rear-wheel drive, but the 128ti is a thoroughly enjoyable BMW to steer, proving the 'f' in front-wheel drive can stand for fun. It’s a very good hot hatch.

And given how expensive mainstream hot hatches have become, the 128ti is a bargain, giving would-be Golf GTI, Focus ST and i30 N buyers a thing or two to think about.

After all, the 128ti is a premium hot hatch by virtue of the BMW badges it wears and the higher quality of its parts, but not its price. And for that reason, it cannot be ignored.

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

You can count me among those who aren't fans of the 1 Series' version of BMW’s 'kidney' grille. It’s not just out of proportion, but arguably, misplaced.

In fact, it just spoils the front end, although I'm also not a fan of the bumper's 'smiling' centre air intake.

But, thankfully, that’s where my unfavourable opinion ends, as the angular headlights and hexagonal DRLs look the part, while the 128ti's red-trimmed side air intakes bring a sense of occasion.

And you better be a big fan of red trim, as the 128ti liberally applies it around the side, where the brake calipers have some presence behind the attractive 18-inch Y-spoke alloy wheels. And don’t forget the side skirt insert and 'ti' decal!

At the rear, aside from the obligatory '128ti' badge and the relatively subtle red-trimmed side air intakes, there isn’t much to separate the 128ti from a garden variety 1 Series, but that’s no bad thing as it's its best angle.

The sporty rear spoiler, sleek tail-lights, stupendous diffuser insert and scintillating dual exhaust tailpipes are gorgeous. And the 128ti is attractive in profile, thanks to its appealing silhouette and smoothly sculpted lines.

Inside, the 128ti stands out from the 1 Series crowd with the red stitching applied to the steering wheel, seats, armrests and dashboard, while the floor mats have – you guessed it – red piping.

The most interesting design flourish, though, is the red-stitched ti logo on the centre armrest. That's one way to make a statement, and it all combines to make the 128ti feel special.

And being a 1 Series is a leg-up in the first place, as high-quality materials are used throughout, in concert with a simple but effective design.

Mercifully, the centre stack features physical climate and audio controls, while the centre console has an appropriately sized gear selector and a rotary dial to control the multimedia system.

That's right, the 128ti has multiple input methods aside from the 10.25-inch central touchscreen and voice control, making it a relative breeze to operate, especially with Apple CarPlay and Android Auto support of the wireless variety.

That said, there's plenty of room for improvement for the 128ti's 10.25-inch digital instrument cluster, which lacks the breadth of functionality of its competitors.

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

Measuring 4319mm long (with a 2670mm wheelbase), 1799mm wide and 1434mm tall, the 128ti is a small hatchback in every sense of the term, but it makes the most of its size.

The boot's cargo capacity is competitive, at 380L, although it can be increased to a more accommodating 1200L by stowing the 60/40 split-fold rear bench.

Either way, there's a decent load lip to contend with, but four tie-down points, two bag hooks and a side storage net are on hand for securing loose items.

In the second row, there's a welcome four centimetres of legroom behind my 184cm driving position as well as a centimetre or two of headroom, even with our test car’s optional panoramic sunroof.

Three adults can sit on the rear seats on short journeys, but they will have next-to-no shoulder-room, plus a large central tunnel (necessary for AWD 1 Series variants) to deal with.

Young children are accommodated, though, with two ISOFIX and three top-tether anchorage points available for fitting child seats.

Amenities-wise, those in the back have access to the storage nets on the front seat backrests, clothes hooks, the centre console's directional air vents and two USB-C ports.

The door bins can take a regular bottle each, but there isn't a fold-down armrest with cupholders.

Up front, the glove box is surprisingly large, while the driver-side cubby is not only decently sized, but two-tiered. The central storage bin is also solid, and has a USB-C port hidden inside.

Ahead of that are a 12V power outlet, a pair of cupholders, a USB-A port and a narrow, open cubby that should house a wireless smartphone charger (but doesn't). And yes, the door bins are ready to swallow a regular bottle apiece. So, pretty damn good overall.

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

BYD will offer the Sealion 8 in three trim levels, starting with the front-drive Dynamic at $56,990, before on-road costs, then moving to a pair of all-wheel-drive variants, the first with the same Dynamic trim level at $63,990 and the range-topping Premium AWD at $70,990.

The Dynamic trim level on both the front-wheel drive and the all-wheel drive variant gets you three-zone climate-control, air vents in both rear rows, full connectivity including wireless Apple CarPlay and Android Auto. There’s also wireless phone charging. The Dynamic specification also takes on 20-inch alloy wheels and there’s full LED lighting as standard.

Pony up for the Premium trim and you make the switch to 21-inch alloys, a 21-speaker sound system and even a massage function for the first two rows of seats. The Premium also includes a head-up display for the driver.

Not as easy to quantify is the level of plush inside the cabin. There are lots of soft-touch surfaces and the whole interior design looks pretty fresh and modern and well put together. But more than that, there’s a bit of design flair that makes the BYD feel perhaps a bit more expensive than it really is. That’s not an easy thing to pull off. But it seems to work here, even in the entry-level Dynamic trim.

Against the competition, the Sealion 8 can't match the similarly specified Chery Tiggo 8 on price, even though on performance and EV range, the Tiggo 8 and the entry-level Sealion 8 are quite similar. The more expensive Sealion 8 Premium, meanwhile, lines up pretty neatly on price with the Kia Sorento S PHEV. But that vehicle can't get close to the epic straight-line performance of the BYD.

The 128ti is motivated by a familiar 2.0-litre turbo-petrol four-cylinder engine, with its version producing a promising 180kW of power at 6500rpm and 380Nm of torque from 1500-4400rpm.

Disappointingly, Australian examples are detuned relative to their European counterparts, which are 15kW/20Nm more potent due to their market-specific set-up.

Either way, drive is sent to the front wheels via a dependable ZF eight-speed torque-converter automatic transmission (with paddle-shifters) and a determined Torsen limited-slip differential.

This combination helps the 128ti sprint from a standstill to 100km/h in a brisk 6.3 seconds while on the way to a not-in-Australia top speed of 243km/h.

For reference, competitor outputs are: M135i xDrive (225kW/450Nm), Golf GTI (180kW/370Nm), i30 N Premium (206kW/392Nm), and Focus ST X (206kW/420Nm).

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

The 128ti's fuel consumption on the combined cycle test (ADR 81/02) is a promising 6.8L/100km, while its carbon dioxide (CO2) emissions are 156g/km.

However, in real-world testing, I averaged a reasonable 8.4L/100km over an even combination of urban and highway driving. Without my heavy right foot, an even better return could be had.

For reference, the 128ti's 50L fuel tank takes more expensive 98 RON premium petrol at minimum. Its claimed driving range is 735km, but in my experience, I got 595km.

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

So, can a FWD BMW be fun to drive? As far as the 128ti is concerned, the answer is a resounding yes.

Yes, you get the feeling you’re being pulled rather than pushed, but the 128ti attacks corners with entertaining vigour.

Of course, the 2.0-litre turbo-petrol four-cylinder engine’s 180kW/380Nm outputs can easily overwhelm the front wheels off the line, and torque steer is a threat, particularly when pushing hard around bends, but they’re welcome characteristics.

After all, corner exits are improved by the 128ti’s Torsen limited-slip differential, which works hard to optimise grip when you need it most.

When going for the jugular, understeer still rears its ugly head, but wrestling the 128ti into shape is half the fun.

That said, body control isn't quite as strong as hoped. Turn in sharply and the 1445kg 128ti generates a surprising amount of roll.

It’s worth noting the lowered sports suspension goes without adaptive dampers, its fixed-rate set-up attempting to find the delicate balance between comfort and dynamic response.

All in all, the 128ti's ride is firm but well judged, with short, sharp imperfections the only real bother. Needless to say, it’s capable of being a daily driver, and so it should be.

As mentioned, the electric power steering has a unique calibration, and it's nice and direct, with a good amount of feel. But if you prefer more heft, simply engage 'Sport' mode.

Speaking of which, the Sport drive mode also releases the full potential of the engine and the eight-speed auto, sharpening up the throttle and raising the shift points.

The 128ti engine is a gem, offering up plenty of punch, especially throughout the mid-range, where torque is at its fattest and power is about to peak. The accompanying soundtrack also has some presence, even if it is artificially 'enhanced.'

But the smooth yet relatively quick shifting automatic transmission can take plenty of credit for the brisk performance on offer.

That said, the 128ti's first and second ratios are surprisingly short, so pay attention if you take matters into your own hands via the steering wheel’s paddle shifters.

The first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

Any family car needs to be safe, so BYD has thrown the kitchen sink at the Sealion 8 in terms of its active and passive safety gear. That starts with nine air-bags including full-length curtain side bags and a centre-front airbag to help prevent head clashes.

There’s also a 360-degree camera on all grades, front and rear parking sensors, and the full line-up of current driver-assistance functions including autonomous emergency braking, lane-keeping assistant, rear-cross-traffic alert and assistance, blind-spot monitoring, driver attention monitoring and a tyre-pressure monitoring system.

To that lot, you can add adaptive cruise-control, traffic-sign recognition, adaptive headlights, front and rear collision warning, anti roll-over systems and hill-hold functions. It’s also worth mentioning that the overhead camera system is very, very good with a clear, crisp display and no processing delay.

The driver-attention monitoring seems to behave itself better than some of the over-active systems other makers specify, but the lane-keeping assistance function is still far form perfect. To be fair, it is less aggressive than some such systems and the intervention is more subtle, but the recued aggression seems to be packaged with lower sensitivity. As in, the cameras seem to sometimes miss a critical white line, particularly if its faded or less than freshly painted.

There are also ISOFIX child restraint tether points in both the second and third rows, as well as seat-belt warnings for every position and an electronic child-safety switch for the doors.

The Sealion 8 is yet to be crash tested locally, so no ANCAP star rating is available.

Like all BMW models, the 128ti comes with a three-year/unlimited-kilometre warranty, which is two years off the five years/unlimited km premium benchmark set by Audi, Genesis, Jaguar/Land Rover, Lexus, Mercedes-Benz, and Volvo.

The 128ti also comes with three years of roadside assistance, while its service intervals are average, at every 12 months or 15,000km, whichever comes first.

Capped-price servicing packages are available, with three years/40,000km starting from $1350, while five years/80,000km kicks off at $1700. The latter, in particular, offers great value.

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.
