BMW 1 Series vs BYD Sealion 5

What's the difference?

A brief dalliance with the 1 Series has left me impressed, if wanting to spend more time with it to get a better assessment of the day-to-day liveability of BMW’s entry-level model.

It’s a compelling offering if you’re after a premium small car, and even without the performance of the M135, the 118 is feature-packed.

Keeping pricing competitive should help the 1 Series buck the trend of buyers opting for small SUVs, but ultimately it’s just refreshing to see BMW putting effort into keeping a hatchback relevant (and up-to-date).

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

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.

The 1 Series has worn many faces over the generations and, like a lot of BMW designs that depart from tradition, this one might need to grow on some people.

That’s not to say there’s not a lot to like about the F70, but as BMW evolves its design language some changes might ruffle feathers - a lack of the iconic ‘angel eye’ headlight style being one.

But there’s still a kidney grille up front, with new design elements, plus those headlights that have a new vertical light signature are now sleeker than before, giving the new 1 a different ‘character’.

But from the rear, there are baby 3 Series Touring vibes, and it’s hard to find anything that might upset purists - there’s even the 'Hoffmeister kink' at the c-pillar. That’s the way the window angles back towards the front at the bottom.

Inside, the 1 Series has some proper sporty elements, even in the 118, that reference the M development that went into it.

There’s M-coloured stitching up over the dash fabric, for example, and illuminated aluminium panels with M-coloured lighting.

The steering wheel, wrapped in leather, is also an M feature, plus sporty seats are even present in the 118.

The interior is an overall cleaner look, in part thanks to the proliferation of features accessible by touchscreen, but BMW is refraining from going full ‘Tesla’ and removing all the buttons from the cabin.

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.

Yes, a brand like BMW would probably find it hard to do away with buttons for things like drive modes and things like volume controls or car settings.

Even though a lot of them are shortcuts to a touchscreen menu, it means not needing to scroll or hunt for important driving-based features and options on the 10.25-inch screen.

Even the climate controls are permanently available on the screen so that there’s minimal distraction.

For most non-essential features, however, BMW’s Operating System 9 is a far cry from the easy-to-use iDrive system of just a few years ago, the media control wheel that fell easily to hand and navigated a simple multimedia system of only a few sub-menus.

Fortunately, the screen and everything in the cabin is within reach of the driver, so there’s no awkward leaning or stretching to do anything mid-drive.

The cabin’s physical space is otherwise nicely laid-out, the phone charger pad is out of the way, cupholders fit most receptacles nicely and the door card can hold two regular water bottles plus other small items.

There’s even a small storage ‘shelf’ under the central vents, and near the wireless charger are two USB-C ports and a 12-volt plug.

The ergonomics of the driving position and steering wheel are well-sorted, and seat adjustment and height feels good for both engaged or relaxed driving positions.

Behind that, the second row could be more spacious, even though I managed to fit my 178cm frame behind my own seating position just fine.

There’s not a lot of room to move or stretch out, so most adults will probably find the back seat suitable for short trips only.

Behind that, there’s 380 litres of boot space, or 1200L with the seats folded down.

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.

The two 1 Series variants have rather different running gear.

The 118 comes with a 1.5-litre three-cylinder turbo petrol engine that drives the front wheels via a seven-speed dual-clutch transmission (DCT).

It makes 115kW and 230Nm, and BMW says it’ll hit 100km/h in 8.5 seconds.

That’s in comparison to the beefier 2.0-litre four-cylinder unit in the M135, also turbocharged, but driving all four wheels via a similar seven-speed DCT.

It makes 233kW and 400Nm, and it’ll crack 100km/h in 4.9 seconds according to the Bavarian brand.

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.

BMW says the 118 will sip 6.4 litres of recommended 95 RON fuel for every 100km covered, with its 49-litre tank the same as the M135’s.

In that variant, fuel use increases to 7.8L/100km, as does recommended fuel quality to 98 RON.

We didn’t get a chance to test fuel consumption properly on the launch, so keep an eye on a future review for that, but given the relatively high claim even for the 118, we’d expect the 1 Series isn’t the most frugal drinker.

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.

The launch drive for the 1 Series included some outer-suburban Melbourne traffic, a stint of highway driving down towards the Mornington Peninsula, and a semi-rural road loop for each variant before the return journey.

So, noting that we didn’t quite get the chance to really work out what it might be like to live with the 1 Series day-to-day, first impressions showed good signs.

Both variants still drive much like you’d expect from even a front-drive BMW, let alone the AWD M135, but the chassis and suspension seem like they’d be good counterparts on a daily drive.

In the M135, communication and compliance seemed well-balanced with each other for even some particularly rough surfaces, and after torrential rain there were some potholes that would properly upset most cars that didn’t faze the 1 Series too much.

The 118 seemed to let a little more road noise into the cabin, but that might have been a symptom of different road surfaces.

The steering is accurate, but the feel in both is a little heavier than needed, especially with the thick-rimmed BMW steering wheel that you’ll know about if you’ve driven anything from Munich in recent years.

It’s a very easy car to drive fast, especially with the combination of 233kW, 400Nm, and all-wheel drive at the M135’s disposal.

The chassis and tyres work quite well together to not only hold a corner at impressive speed, but also keep the car stable so that traction isn’t an issue when launching out.

There’s also the joy of hearing a turbo spool and flutter under load, which is hard to deny as a draw for petrolheads.

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.

BMW’s got a fairly standard five-year/unlimited kilometre warranty.

The brand also uses a condition-based servicing system, which uses the multimedia to alert the owner when maintenance is required.

There are servicing packages which remove some of that uncertainty, in the 1 Series’ case a five-year, 80,000km pack costs $2210.

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.
