BMW M235i vs BYD Sealion 5

What's the difference?

The badge might say one thing, but the 2 Series Gran Coupe sticks to the time-honoured template of being a compact yet comparatively practical three-box, four-door sedan, complete with a big boot.

More importantly, it drives and behaves like a BMW – which means sufficient-to-strident performance depending on grade, athletic dynamics and pleasing refinement on one hand, as well as a stiff price and a hard ride on the other.

A true BMW in name and nature, then..

Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.

The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.

BMW is calling the F74 a new-generation 2 Series Gran Coupe, and there have been obvious and even profound changes throughout and underneath, including to some of the sheetmetal.

But this is not an all-new car by any stretch, with the glasshouse, doors and roof amongst many other body items carrying over from the F44.

That now remarkably Kia Cerato-esque nose ushers in new LED lighting motifs and an updated kidney grille, but whether they sit easily with the rest of the car is debatable. Redesigned tail-lights, different colours and new alloys make up the majority of the exterior changes.

Betraying the latest 2 Series Gran Coupe’s newness claims are near-identical dimensions, with that redesigned front end and bumpers contributing to a 20mm increase in the F74’s 4546mm length, while revised suspension and damper settings help account for the 25mm boost in height (to 1445mm). The BMW’s 1800mm width and 2670mm wheelbase remain the same.

There’s a higher level of newness to be found inside.

The interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.

Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.

During the media presentation at its launch, BMW described the 2 Series Gran Coupe as being almost as large as a 1990s E46 3 Series, and it is in all major dimensions except wheelbase.

Plus, being a front-drive-biased/transverse engine proposition instead of rear-wheel drive should make it roomier than the F74’s iconic ancestor.

The sense getting in is that this is certainly not too low or cramped as per a more-traditional coupe, with plenty of space for legs and shoulders, while even the optional sunroof fitted to our 218 left us with headroom to spare.

The redesigned dash is a visual and operational treat, with crisp, clear instruments, a logically presented and intuitive centre display screen offering fast and easy operation, excellent ventilation and ample storage. Full marks here.

Better still, attaining the perfect driving position is possible for most people, on brilliantly supportive front seats. This is the stuff BMW does right.

Improvement suggestions for the next update? Some people may complain about the somewhat less-than-premium feel of some of the lower-lying plastic trim; not everybody will love the swatches of colour stitching (we love it); why does the steering wheel have to be so wide-of-rim? Side and rear vision is restricted by fat pillars, rising shoulder lines and a shallow rear window; and there is quite a bit of road noise that enters the cabin at speed.

Still, even the back seat is sufficiently spacious for most users, with the sole exception of taller folk having to negotiate a sloping rear roofline. If you’re below 180cm, this should be fine. Most amenities minus overhead grab handles are also fitted.

Further back, the boot is surprisingly accommodating, with 430 litres of cargo capacity that’s enhanced by a 40:20:40 split-fold backrest, and the aperture should be big enough for bulkier loads, but the lack of a spare wheel will be bad news for many buyers. The supplied tyre-repair kit is just not good enough.

But, you know what is good enough? The engines BMW builds, that’s what.

Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.

The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.

The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.

With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.

Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.

As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.

The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.

The plug-in hybrid in question is the BYD Sealion 5. It has a claimed EV-only range of better than 100km, relatively quick charging, a decent sized battery, adequate performance, enough interior space for a family, good safety and lots of equipment. Oh, and it costs just $33,990, before on-road costs, in its entry-level Essential form. Incoming!

Equipment-wise, that sub-34K sticker gets you a 10.1-inch central info-screen, an 8.8-inch driver display, digital radio, a six-speaker stereo, wireless connectivity for Android Auto and Apple CarPlay and dual-zone climate control.

Throw another four grand on the table and you move up to the Premium version which adds plenty of kit for the $37,990 ask. That includes a panoramic sunroof, automatic tailgate, roof rails, heated and electrically folding mirrors, one-touch power windows, a six-way powered drivers seat and four-way powered co-pilot’s chair, a heated and ventilated driver’s seat and wireless charging.

The step up from Essential to Premium also includes a battery upgrade, and we’ll cover that off in the Under the Bonnet section below.

Three F74 powertrain choices are available for Australia in 2025. And none even remotely reflect what their respective badges imply on the boot.

The 218, for instance, is not powered by a 1.8-litre engine, but BMW’s long-lived B38 1.5-litre three-cylinder turbo petrol unit. Making 115kW of power at 6500rpm and 230Nm of torque between 1500rpm and 4600rpm, drive is channelled to the front wheels via a seven-speed dual-clutch transmission (7DCT).

With a kerb weight of 1420kg, the 218 has a power-to-weight ratio of 81kW per tonne, helping it achieve the 0-100km/h sprint time of 8.6 seconds, on the way to a 230km/h top speed.

Not enough? The 220 features the ubiquitous B48 2.0-litre (not a 2.2-litre) four-cylinder turbo petrol engine/7DCT combo, pumping out 150kW at 6500rpm and 300Nm from 1450-4500rpm. Tipping the scales at 1525kg for 98.4kW/tonne, its 0-100km/h time is 7.3s and top speed is 250km/h.

Want more? Stretching to the M235 xDrive sadly doesn’t mean a 3.5-litre in-line six, but a modified B48 2.0L/7DCT duo, delivering 233kW at 6500rpm and 400Nm from 2000-4500rpm to all four wheels. Result? Weighing just 50kg more than the 220, it boasts a heady 148kW/tonne, for a 0-100km/h of just 4.9s and a 250km/h v-max.

As with all of the UKL2/FAAR transverse-engine front-to-AWD platform models from non-electric Minis through to sub-X3/3 Series BMWs, you’ll find MacPherson-style struts up front and a multi-link independent rear end out back.

If you’re reading this outside of Australia, you may notice that none of the current F74 models offer mild-hybrid tech, in contrast to their European counterparts. And don’t go expecting any manual gearboxes either, unfortunately.

Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.

Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.

The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.

A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.

OK, so is the 2 Series Gran Coupe cheap to run?

BMW reckons the 218 and 220 will average 6.3 and 6.7 litres per 100km, which means combined average carbon dioxide emissions ratings of 143 and 152 grams/km respectively.

Filling the 49L fuel tank with 95 RON premium unleaded, that translates to around 775km in the 218, and 730km in the 220 between refills.

Predictably, the M235 xDrive uses more, at 7.7L/100km for a CO2 rating of 176g/km. That’s a distance of about 635km.

Over our launch run, which took us from Sydney’s Circular Quay to Wollongong, the 218’s trip meter was reading in the high 8s and about 10 for the M235.

The Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.

There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.

Earlier, we mentioned that the 2 Series Gran Coupe is way more expensive than fine alternative sedans like the Mazda3 and Toyota Corolla.

And while that still stands, there is a remarkable solidity and refinement difference between those and the BMW that helps justify the premium. And nowhere is this more evident than from behind the wheel.

Sat on body-hugging seats and clutching that (too chunky) steering wheel, there is a sense of sporty occasion, backed up by quality trim and an aroma of expensiveness.

For a turbo three-cylinder car weighing 1.5 tonnes, the 218 does a lot with a little, offering spirited off-the-line acceleration and pleasingly lag-free throttle responses at lower speeds. You’d never call it fast, but it is a quick point-to-point urban mover. Only the unavoidable three-pot thrum lets you know you’re in the lowest mechanical spec. And, also, the delay at freeway speeds in building momentum when overtaking.

Which is why, for less than five per cent extra, the 220 with the 2.0-litre four-cylinder turbo would probably make a better buy. Sadly, that isn’t on sale yet in Australia, so we missed out on driving it during the Sydney launch. But in the scores of other BMWs and Minis we’ve tested this in, it’s a cracking little powertrain.

Whether the big leap (nearly $25K worth) to the M235 is worth it depends on how fast you drive and how much you value/need AWD. This is a terrifically muscular machine, since it provides rapid performance via a tidal wave of power, even with the lightest flex of your right foot. On-point and on-brand, this fun and fiery flagship possesses the grand-touring spirit that the rakish design and tech-heavy engineering promise.

To that end, in both the 218 and M235, the steering makes the driver feel connected to the car, resulting in precise and controlled handling. The driver-assist safety tech is beautifully calibrated and nuanced in its intervention, and the brakes are second-to-none.

What is also on-topic for a BMW is the firm suspension, despite the adaptive dampers fitted as standard equipment.

It isn’t stiff or overly uncomfortable, but bumps are certainly always felt, and they’re accompanied by fairly constant road-noise drone over some surfaces.

As such, you’re constantly reminded that dynamic athleticism is the priority here, rather than sumptuous comfort. We’ve experienced much worse from BMW, but a magic-carpet ride isn’t what’s in store for the 2 Series Gran Coupe owner.

So, what’s our verdict then? The 218 is a rorty little tryer that never fails to involve the driver, while the M235 ushers in an elevated level of acceleration, grunt and grip. We suspect that the 220 will be the Goldilocks-zone happy medium.

For (largely) better as well as for (occasionally) worse, these drive and feel like a BMW should.

You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.

Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.

In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.

Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.

Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.

On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.

The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.

Passive safety in the Sealion 5 starts with no fewer than seven airbags including full-length side-curtain bags. 

There’s also a front-centre airbag, something we’d like to see in more cars, particularly at this price-point. Child restraint points in the rear seat are the ISOFIX type.

The BYD gets pretty much the full suite of driver aids, including autonomous emergency braking, blind-spot monitoring, rear-cross traffic alert with active assistance, stability control, active cruise-control, traffic-sign recognition, front and rear collision warning and tyre pressure monitoring.

The Sealion 5 also incorporates a driver-attention monitor which seems better calibrated than some earlier efforts from some of the Chinese carmakers. Also improved in calibration terms is the lane-keeping assistance which is still too violent for our tastes, but more subtle than some of the competition’s systems. But while the savagery of this system has been toned down, it appears to have been at the expense of sensitivity and, time and time again, the cameras missed road markings that were faded or dirty.

The major safety benefit in paying more for the Premium variant is the addition of front parking sensors and a 360-degree camera instead of the Essential’s simple reversing camera.

The Sealion 5 has not been ANCAP tested as yet, although BYD says this is largely down to ANCAP’s scheduling rather than any hesitance on BYD’s part.

Here, however, is where BMW can do a bit better.

While the five-year/unlimited-kilometre warranty is where most premium brands are, it falls short of several Asian alternatives. Roadside assistance is for just three years and there is no capped-price servicing.

Service scheduling is also condition-based, meaning the vehicle will alert the driver when a service is imminent. This may not suit everybody, and we always recommend at least every 12 months or 10,000km, just to be on the safe side.

BMW does offer pre-paid service packs that take in basic maintenance for the first five years at $2369 or $3782, including brake-pad replacement, which works out to be about $475 and nearly $760 annually respectively. There is also a cap on mileage during that time frame: 80,000km.

Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.

The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.

BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.

Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.
