BYD Sealion 8 vs BMW 228i

What's the difference?

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.

The BMW 2 Series coupes and convertibles combine understated good looks with great dynamics and top-shelf quality. Extra equipment, especially the iDrive6 multimedia system, has brought it up to speed in terms of tech and value, while the M240i sets the compact performance benchmark. And if you really want to push the envelope, the M2 is right there at the top of the under $100k performance pyramid.

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.

The biggest visual clue to the revised 2 Series is the circular design bi-LED headlights, now standard on the 2 Series entry 220i, and mid-range 230i models, while hexagonal adaptive LEDs are standard on the top-shelf M240i.

But BMW couldn't leave those little light-emitting diodes alone, with LED front fog lights joining one-piece L-shaped LED tail-lights across the range.

Luxury Line-equipped cars feature a subtly revised nose treatment with larger intakes and a reshaped 'kidney' grille. There are also four new alloy wheel designs – a 17-inch alloy fitted standard to the 220i Luxury Line, and three optional M alloys for M Sport models (all no-cost options on the M240i).

The 230i M Sport features black, high-gloss bars in its kidney grille, as well as a black chrome finish for the exhaust finishers.

On the inside, there's the addition of a 'Black Panel' digital instrument cluster, which remains matt with the ignition off, and lights up with sharp graphics, configurable across conventional speed and rev readouts, as well as gear position, engine-efficiency data, vehicle settings and nav guidance.

There are also high-gloss finishes across the centre stack and front console, and even greater attention to detail around panel joins, trim stitching and switchgear.

But the hero is the latest iDrive6 multimedia system, run through an 8.8-inch colour touchscreen (6.5-inch on 220i), providing access to live content, radio and audio, navigation and maps, phone functionality, and vehicle settings through a simple and customisable app-style interface. The iPhone really as inspired car companies.

The M2 boasts M-specific instrument display content and a go-fast red needle on the tachometer.

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.

Surprisingly, at a little over 4.4 metres long, the 2 Series (Coupe) is around 10cm longer than its 1 Series hatch stablemate (M240i +15cm), but aligns with its just under 1.8m width, and 1.4m height.

It seats four, with plenty of room up front and multiple storage options, including two cupholders in the console with an oddments tray behind, a 12-volt outlet, a lidded storage box between the seats with USB connection, a reasonably sized glove box, and segmented bins in the doors big enough for large water bottles.

While it was coupes only on the launch drive, we know the convertible has a pair of cupholders in the back, but not so in the coupe, and while headroom in the soft-top is okay (especially with the roof down) it's a squeeze in the hardtop.

More a 2+2 than a full four-seater, getting into the rear is an athletic exercise, and once installed, leg and headroom for this 183cm tester is tight. That said, kids up to teenager-size would be fine.

Boot volume is 390 litres (a 3 Series Coupe is 480 litres), with run-flat tyres on the 220i and 230i meaning there's no spare (or repair kit) under the floor, but the performance-focused M240i and M2, pack a 'BMW Mobility Kit' (compressor and tyre sealant to cover minor damage) in line with their high-performance (non-run-flat rubber).

A 60/40 split-folding rear backrest liberates extra load space, and a 'Through Loading System' with luggage compartment dividing net, and 40/20/40 split-folding rear seat is optionally available (220i & M2 Pure - $350 / 230i - $385 / M240i & M2 - $500).

And if you're keen on towing the 220i can pull 680kg of unbraked trailer, and 1500kg braked, with the minimum number stepping up to 715kg for the 230i. The M240i and M2 are no-tow zones.

The 2 Series coupe and convertible line-up ranges across four-cylinder, turbo-petrol models, in 220i Luxury Line, and 230i M Sport grades, with the six-cylinder M240i sitting at the top of the main line-up. Then for the more single-minded enthusiast, there's the hardcore M2; after a year on-sale it's now BMW Australia's best-selling M car (and it's easy to see why; it's fantastic).

Depending on the model, prices have risen by between $1100 and $1900 across the main range, largely because of the extra equipment, especially the tricky iDrive6 multimedia system.

At $52,990 for the coupe and $59,900 for the convertible version, the 220i Luxury Line is the entry-point to the 2 Series range. Equipment highlights include 17-inch light-alloy wheels, the previously mentioned LED headlights and fog lights, 'Driving Assistant' functionality (combines camera-based 'Lane Departure Warning and Approach' and 'Pedestrian Warning with the City Brake Activation'), digital radio, 'Navigation System Business' with 'iDrive6' accessed via a 6.5-inch display, dual-zone climate control air, reversing camera, a leather sports steering wheel, sports front seats, 'Dakota' leather upholstery, plus front and rear parking sensors.

Next rung on the 2 Series ladder is the 230i M Sport in Coupe ($63,000) and Convertible ($73,000) form, which adds M Sport suspension, aero, and brakes, 'Variable Sport Steering', 18-inch alloy rims, high-gloss 'Shadow line' exterior trim, a BMW Individual anthracite roofliner, a leather-wrapped M Sport steering wheel, cloth/Alcantara upholstery in the coupe, 'Dakota' leather and front seat heating in the convertible, electric (front) seat adjustment, plus 'Navigation System Professional' with iDrive6 and a customisable 8.8-inch touchscreen.

As its name implies, the M2 Pure ($93,300) makes spec sacrifices in the name of light weight.

Opt for the M240i as a Coupe ($76,800) or Convertible ($85,800), and you're getting more than extra performance from the 3.0-litre turbo six. On top of the lengthy equipment list detailed above, you'll also pick up 18-inch alloys in 'Bicolour Jet Black', 12-speaker, 360W harman/kardon surround sound audio, 'Adaptive M Suspension', 'Adaptive LED Headlights', the Dakota leather trim, and front-seat heating.

As its name implies, the M2 Pure ($93,300) makes spec sacrifices in the name of light weight, including manual seat adjustment and a base (yet, still seven-speaker) audio package, but one of the biggest pay-offs is a standard six-speed manual gearbox. Save the manuals!

It also features 19-inch BMW M light alloy wheels, an M rear spoiler, quad exhaust pipes in high-gloss chrome, bi-LED headlights (with variable light distribution, including cornering lights), 'Dakota' leather upholstery, carbon fibre trim finishers, an M leather multi-function steering wheel, cruise control (with braking function), 'Driving Assistant', 'Rear Park Distance Control', and a reversing camera.

The full-fat M2 Coupe ($99,900) reinstates electric seat adjustment, plugs in the 12-speaker, 360W harman/kardon sound system, and adds 'Comfort access' (keyless entry and start), 'Adaptive LED Headlights' (with variable light distribution), and 'Selective Beam with anti-glare High-Beam Assistant'.

A vast array of individual options and packages covers everything from steering-wheel heating to a smoker's kit (naughty), and (amazingly, given it's standard on the Hyundai Accent) Apple CarPlay (220i & M2 Pure - $436 / 230i - $479 / M240i & M2 - $623).

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 220i is powered by a 2.0-litre 'TwinScroll' turbo-petrol four, featuring 'Valvetronic' variable valve control and 'Double-VANOS' variable camshaft control, and developing 135kW at 5000rpm, and 270Nm between 1350-4600rpm.

Using a retuned version of the same engine (lower compression ratio, more turbo boost), the 230i pumps out a solid 185kW at 5200rpm, and a grunty 350Nm from just 1450-4800rpm.

The same (8HP50) eight-speed auto transmission is used across the board, pushing drive to the rear wheels only.

Then, the M240i is powered by a 3.0-litre, six-cylinder, turbo-petrol, pushing out no less than 250kW at 5500rpm, and a thumping 500Nm between 1520-4500rpm.

The same (8HP50) eight-speed auto transmission is used across the board, pushing drive to the rear wheels only, and happily, a six-speed manual gearbox is a no-cost option on the M240i.

The full-house M2's 3.0-litre turbo six produces 272kW at 6500rpm, and 465Nm from just 1400-5650rpm (500Nm from 1450-4750rpm on overboost), driving the rear wheels through a seven-speed dual-clutch auto, although a six speed-manual is a no-cost option (and standard on the M2 Pure).

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.

Claimed fuel consumption for the 220i Coupe, on the combined (ADR 81/02 - urban, extra-urban) cycle, is 5.9L/100km, emitting 135g/km of C02 in the process. The 220i Convertible rates 6.1L/100km (140g/km).

The 230i Coupe is line-ball with that at 5.9L/100km (134g/km), and the the 230i Convertible at 6.2L/100km (142g/km).

The price of performance starts to bite with the M240i consuming 7.1L/100km (163g/km) in coupe form, and 7.4L/100km (169g/km) as a convertible.

Then, as you might expect, the M2 is thirstiest of all, the dual-clutch auto consuming 7.9L/100km (185g/km), while the six-speed manual version slurps 8.5L/100km (199g/km).

Auto start-stop is standard, fuel tank capacity is 52 litres across the board, and although technically these engines can run on anything from 91-98RON unleaded, BMW recommends 95RON premium as a minimum.

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.

Four 2 Series variants were offered for the launch drive program, a 230i Coupe (which BMW nominates as the most popular model in the range), M240i Coupe, M2, and M2 Pure.

Claimed 0-100km/h acceleration of 5.6sec for the 230i M Sport Coupe is quick, with the convertible stopping the clocks three tenths later.

Peak torque of 350Nm is plenty, and with that number available from 1450-4800rpm the mid-spec 2 Series is an entertaining drive.

It's M Sport (strut front, five-link rear) suspension keeps the body well buttoned down in quick going, while the beefier M brakes provide strong and progressive stopping power.

Even a firm squeeze of the throttle can't side-step some hesitation as the turbo spools up before right foot pressure translates into forward momentum, but despite the sporty tune, ride quality is good (even riding on notoriously harsh 18-inch run-flat rubber), while response and road feel from the variable-ratio steering are excellent.

The eight-speed auto is beautifully slick, with manual changes, via wheel-mounted paddles, sharp and positive.

Add the grippy leather sports wheel, snug sports front seats, and racy cloth/Alcantara trim (leather in the convertible), and you have a comfortable, nicely balanced and fun-to-drive package.

Accelerating from 0-100km/h in 4.6sec (convertible 4.7sec), the M240i effortlessly achieves 'genuinely rapid' status. Yes, it's fast, but never furious, in the sense that even under the pressure of enthusiastic peddling it remains civilised and composed.

Maximum torque of 500Nm is not to be sneezed at, and when you realise that mountainous maximum is actually a flat-top plateau stretching from only 1520rpm up to 4500rpm, satisfying urge is never far away. And the flexible 3.0-litre turbo-six is an aural treat as it howls its way towards a 7000rpm rev ceiling.

The standard 'Adaptive M Suspension' offers settings from 'Comfort' through to 'Sport+', but even in the most forgiving mode the car remains taut and communicative.

The 18-inch rims, shod with Michelin Pilot Super Sport rubber (225/40 front / 245/35 rear) don't upset the ride as much as you'd expect, although coarse-chip surfaces send rumble through to the cabin.

In terms of ergonomics and general function, the new iDrive6 system is simple and intuitive to use, the current BMW dash and console layout is a model of efficiency, but the two-stage (depress small button on stubby lever, then shift) process to select drive or reverse can be a frustratingly hit-and-miss affair if you need to get going quickly.

Then, the M2 is all business, with a properly focused feel, and the ability to accelerate from 0-100km/h in a claimed 4.5sec for the six-speed manual, and just 4.3sec for the seven-speed dual-clutch. Try not to smile as that g-force shoves you back in your seat. You won't succeed.

Although peak power arrives at a relatively high 6500rpm, maximum torque of 465Nm (500Nm for limited periods on overboost) is ready for action across a broad spread from 1400-5650rpm, so the M2 has adrenalin flowing through its veins at all times.

An electronically controlled 'Active M Differential' manages torque distribution across the rear axle to optimise power down, with the ability to send anywhere from zero to 100 percent of drive to either back wheel.

The 'M Servotronic' steering, switchable through comfort and sport modes, is feelsome and linear in its response, the mega 'M Compound Brake' package (borrowed from big-brother M4) is professional grade, and while the seven-speed dual-clutch may shift faster, snicking up and down the manual's six ratios is a rare pleasure.

Rolling on 19-inch, ultra-high-performance Michelin semi-slick rubber (255/35 front / 275/35 rear) the M2 is never going to waft like a limousine, but if you're signing on for this kind of performance and dynamic ability, some ride harshness over less than perfect surfaces goes with the territory.

Across the mainstream 2 Series line-up (220i to M240i) driver-assistance tech including AEB, forward-collision warning, pedestrian-detection and lane-departure warning is standard.

There are also 'Approach Control Warning', 'Attentiveness Assistant', and 'Pedestrian warning' systems, plus 'Dynamic braking lights, DSC, ABS, 'Braking Assistant', 'Cornering Brake Control' (CBC), 'Dynamic Traction Control' (DTC), cruise control with braking function, a reversing camera, 'Park Distance Control' (PDC) rear (front and rear on 120i and up), and run-flat safety tyres (including a run-flat indicator) for the 220i and 230i. Tyre pressure monitoring is standard on the M240i and M2.

There are two child restraint top tethers across the back seat, with ISOFIX anchor points in each position.

On the passive safety side, all 2 Series models feature airbags for the front, side and head, as well as 'Intelligent Emergency Call' assistance.

The current BMW 2 Series Coupe/Convertible hasn't been tested by ANCAP or EuroNCAP.

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.

BMW uses 'condition-based' servicing, with the car effectively telling you when it's time to visit the workshop, but the 'BMW Service Inclusive' program offers distance and time options to fix maintenance costs (on a 'Basic' or 'Plus' plan) for up to 10 years/200,00km.

For example, a five year/80,000km service package for the 2 Series costs $1340 for the Basic option (oil service/top-up, annual vehicle check, microfilter, air filter, fuel filter, brake fluid, spark plugs), and $3550 for the Plus pack (adds brake pads and discs, wipers rubbers, and clutch disc and plate).

The standard BMW warranty covers three years/unlimited km.
