BMW X5 vs BYD Seal

What's the difference?

This is a luxurious prestige five-seater brimming with BMW’s latest design and technology that’s not only practical for weekly family duties but can also embrace spirited driving with the push of a button. A great all-rounder for families that like a sporty edge. 

Those big auto executives have good reason to be worried, because the Seal is yet another impressive offering from China’s most formidable EV player.

It’s not perfect. In some ways it’s trying too hard to be a luxury car, and I think the software in particular could use a little work, but the Seal just does so much right I think it will be hard to be disappointed with one, particularly given its keen entry price.

In fact, if we had to pick one from the range, it would probably be this mid-spec Premium. The range and power on offer are stellar, and all for less money than an entry-level Model 3 or Polestar 2.

The latest front-end design features subtle revisions to BMW’s signature 'kidney' grille theme, highlighted by slimmer matrix LED headlights with chevron-shaped DRLs that incorporate the turn indicators.

There’s also an ‘iconic glow’ function, which illuminates the twin-grilles at night in-sync with the external courtesy lights when approaching and departing the vehicle. Lower front air-intake and tail-light treatments have also been revised.

The dash features a new curved instrument panel. Based on BMW’s latest generation 'iDrive' operating system, it consists of a 12.3-inch driver’s info display and 14.9-inch control display presented across the same seamless glass surface.

The control display’s touchscreen functionality has allowed dash buttons and switches to be minimised.

This new design dash has a blend of synthetic leather trim and dark brown/high-gloss woodgrain surfaces, along with new LED ambient lighting and gear-selector design.

The rear seat is sumptuous and spacious, even for someone my height (186cm). There’s ample knee and headroom and it can seat three kids in comfort, but for adult passengers wanting that 'business class' feel it would be ideal for two.

My only criticism of the new instrument display is that with more than 30 applications displayed on the expansive control screen, it can be distracting at times trying to visually locate and operate these functions while driving.

And, depending on sun angle, there were also complaints from different front seat passengers on different days about blinding glare caused by the dash’s high-gloss woodgrain inserts. Fortunately, the driver is unaffected by these reflections.

The Seal looks great. It’s about as modern a take on the traditional three-box sedan as you can get. It’s low-slung with curvy lines and a sporty overall feel.

The design touches, like the headlight and DRL surrounds, side skirts, and wheels are maximalist compared to the minimalist vibes of the Model 3 and the Polestar 2. But I don’t necessarily think that's a bad thing as it offers buyers a genuine alternative.

I also like the way the brand has executed the LED lights and particularly the tail-light fittings. There’s also an admirable restraint when it comes to badging compared to a lot of this car’s Chinese rivals. It doesn’t give off the vibe of a cut-price product at all.

Inside there are elements which are appealing, and some things which fall short. First up, I do think the Seal wears its influences throughout the industry on its sleeve a bit.

The digital dash cluster theme, for example, seems to (poorly) emulate the Mercedes-Benz software, the little plastic crystal shifter piece on the inside seems to have been overtly influenced by a similar (actual crystal) piece available in Volvos, while the centre screen and dual wireless phone chargers are pretty obviously BYD’s take on the similar bits available in the Model 3.

Maybe in this sense, it’s trying a little too hard to be a luxury car and a tech-heavy electric vehicle, with items which aren’t quite up to the same quality (particularly the software). But then, it all works well enough, and can you complain at the price?

One thing I think BYD gets right though is the level of comfort on offer in the cabin and the clever little styling bits which remind you of its namesake.

The door handle pieces and integrated speaker bits are shaped like a Seal flipper. As are the dash-mounted air vents, and if you look closely even the plastic garnish on the steering wheel looks a bit like a top-down cross section of the animal.

I like it because its subtle rather than in-your-face as some of the Atto 3's design elements are.

The quality is also up to muster, big time. There wasn’t a creak, groan, or rattle from this car’s interior in my entire time with it, including on some of Sydney's worst roads. And the seats, which are designed like absolute thrones, are clad in lovely soft leather. You sink into them. Even the two-tone Alcantara finish through the doors and centre console is thoughtfully placed.

With its 2165kg kerb weight and maximum allowable weight of 2885kg, our test vehicle can legally carry up to 720kg.

That should be ample for five adults (even better for kids) and their luggage, of which up to 100kg can be carried on the roof rails using a rack or roof box (both in BMW's accessory range).

Powered upper and lower tailgates provide good access to the luggage area, which is carpeted and equipped with a roll-out privacy screen, load securing hooks, a 12-volt accessory outlet and a first-aid kit stored behind a removable side panel.

The space-saver spare and tools are stored below the hinged load floor, so all luggage must be removed to access them.

Internal luggage space with the rear seat upright is 650 litres (0.65 cubic metres) which expands to 1870 litres (1.87 cubic metres) with the rear seat folded flat.

A useful load-carrying feature when the rear seat’s backrest is upright is a hinged centre section that folds forward and flat to carry long and narrow items.

These can stretch all the way from the tailgate to the dash if need be, which could be handy for carting anything from skis to home hardware purchases (firmly secured, of course).

It’s also rated to tow up to an impressive 3500kg of braked trailer, which matches the class benchmark for one-tonne utes.

However, given that tow-ball download (TBD) is usually around 10 per cent of trailer weight, the X5’s maximum TBD rating of only 140kg could be a challenge if 3500kg towing is required.

Front of cabin storage includes a big bottle-holder and bin in each front door, a glove box and on the right-hand side of the dash a pull-out driver’s bin, both of which are felt-lined.

The centre console, in addition to its wireless phone-charging pad, USB-A port and 12-volt outlet, has two small-bottle/cupholders up front and a large box at the rear, housing a USB-C port and topped by a padded dual 'brochure fold' lid that double as an elbow-rest for driver and front passenger.

Rear seat storage includes a large-bottle holder and bin in each door and pockets on each front seat backrest. The rear of the centre console has two storage nooks for small items in addition to its air-vents, two USB-C ports and a 12-volt outlet. There’s also a handy tablet-mount and USB-C port on each front seat backrest, which is great for long trips.

Folding down the rear seat’s centre armrest reveals two pop-out small-bottle/cupholders. And under its hinged lid is a hidden felt-lined compartment that’s ideal for storing slim screened devices away from prying eyes.

The Seal has a huge cabin, and in a lot of ways it feels like the large sedans of old. You can sit nice and low in the cabin, and there’s heaps of knee and headroom thanks to its width.

Soft-clad materials for resting your knees and elbows on go a long way towards keeping this car comfortable on longer journeys, and the presence of a digital dash and a holographic head-up display is nice to have compared to the bare-bones dash of the Tesla Model 3.

The wacky rotating central touchscreen feature makes an appearance from other BYDs, but again, it’s a bit silly and I’m not sure how much use you’ll get out of it. Even Apple CarPlay only works in landscape mode, so I didn’t find it useful.

Practicality features are abundant, with a large bottle holder in the doors, and two more in the centre console. One even has a floating floor, so you can push it down to accommodate large bottles if need be.

Dual wireless chargers are always a nice touch, and the bridge-style console has a large pass-through storage area underneath, which also hides the USB-C, USB-A, and 12V outlets. The armrest console box is nice and deep, too.

The back seat is enormous. Possibly one of the largest spaces in this segment. It comes at a cost to boot capacity, but your rear passengers won’t want for space no matter how tall they are.

At 182cm tall I had leagues of airspace behind my own driving position, and the wide cabin, accommodating seats, and flat floor mean the centre position is even useful for a full-sized adult.

Storage comes in the form of three pockets on the back of each front seat, a large bottle holder in the doors, two cupholders in the drop-down armrests, a small tray on the back of the centre console, and a small flip-out cover which reveals a USB-C and USB-A charging port for rear passengers. The rear seat even gets dual adjustable air vents, but no third climate zone.

The massive fixed glass roof looks the business and keeps the cabin airy, just like in the Model 3 and Polestar 2, but I find these big glass fittings tend to cook interiors in the Australian sun.

BYD tells us the tint is so heavy it has a ‘solar transmittance’ of just 16 per cent, but 16 per cent is still a lot in Australian summer. Thankfully, unlike its two rivals, BYD ships the Seal with a fold-out cover screen as standard.

Remember how I said the massive rear seat comes at a cost to boot space? At 400 litres the Seal’s boot is a bit compact, made worse by the fact it’s a sedan and not a liftback, so the access area is a bit narrow.

It could only fit the largest CarsGuide luggage case alongside the smallest one, but not all three including the medium case. This could be a blow to family buyers who need to fit a pram alongside other things.

Under the floor there’s an extra space great for the storage of your V2L adapter and AC charging cable, but there’s also only a tyre repair kit and no spare.

Just like its Model 3 rival, the Seal arrives in Australia in three variants - the base Dynamic, top-spec Performance, and the one we’re looking at for this review, the mid-spec Premium.

Price is, of course, BYD’s forte, with this mid-spec Premium (equipped with a long-range battery) even managing to undercut the entry-level Model 3 RWD.

Before on-road costs and state-based incentives you can have one of these from $58,798, while (at the time of writing at least) the enormously popular Model 3 RWD weighed in at $61,900. Its next closes rival, the Polestar 2 Standard Range, costs from $67,400, so value here is obvious.

The Premium’s long-range battery allows a WLTP-certified driving range of 570km between charges which is even one of the longest cruising ranges available on any electric vehicle in Australia right now.

The list of standard features is exhaustive, including 19-inch alloy wheels, LED headlights, a massive 15.6-inch multimedia touchscreen with wired Apple CarPlay and wireless Android Auto, a 10.25-inch digital instrument cluster, a holographic head-up display, dual wireless phone charging bays, built-in navigation and connected services, ‘genuine’ leather seat and wheel trim (a blend of synthetic and real leather), an eight-way power-adjustable seat for the driver, ventilated and heated front seats, dual-zone climate control, a fixed panoramic glass roof and keyless entry with push-start ignition.

The Seal also gets an impressive array of standard safety kit. More on this later.

The only options are premium paints and an alternate light blue theme for the interior which cost $1500 each.

This list of kit would even be impressive on a combustion car at this price, so the fact it’s also electric and offers one of the longest driving ranges on the market is a bonus.

The one area where I think it lacks a little is the stock software. It looks okay and, to be fair, functions a lot better than its Chinese contemporaries and even some other brands, but once you dig into it a little there are some clumsy menus, and it becomes painfully obvious it’s a simple Android reskin. A swing and almost a miss for something so integral to a car like this.

Why is it called the Seal? Well, in BYD’s home market of China, its range is so expansive it has split it up into two model lines, the Dynasty series (named after historical Chinese kingdoms) of which the Atto 3 is a member (it is called the Yuan Plus in China), and the Ocean series which the Seal and Dolphin belong to. The next BYD to arrive in Australia, a mid-size SUV likely to be called the Seal U, also belongs to the Ocean series.

The X5 xDrive40i is powered by BMW’s legendary 3.0-litre DOHC 24-valve in-line six with state-of-the-art technology.

This includes twin-scroll turbocharging, variable valve/camshaft timing and 48-volt mild hybrid technology (delivering up to 9.0kW and 200Nm) using an electric motor integrated with the transmission.

The combined effect is optimised power and throttle response (0-100km/h in 5.4 secs) with minimal fuel consumption and Euro 6d emissions.

It produces 280kW between 5200-6250rpm and 520Nm of torque (this can reach 540Nm with hybrid input) across a remarkably wide and flat peak torque band between 1850-5000rpm, which showcases its flexibility. There’s also auto start-stop and selectable drive modes.

This is paired with BMW’s smooth and sharp-shifting eight-speed torque converter automatic, which combines the best characteristics of a dual-clutch and traditional torque converter transmission.

There’s overdrive on the seventh and eighth gears to optimise fuel economy and the choice of rapid manual-shifting using the steering wheel paddles.

Power reaches its wide tyres through the xDrive intelligent all-wheel drive system, which actively varies the engine’s torque distribution between the front and rear wheels to optimise traction at all times.

BMW’s ‘Efficient Dynamics’ also includes brake energy regeneration with recuperation display and many other standard features to enhance driving safety and efficiency.

Each Seal variant gets its own drivetrain outputs, and the mid-spec Premium drives the rear wheels with a 230kW/360Nm electric motor via a reduction gear.

On paper, it’s slightly more powerful than the Model 3 RWD, with more power and less torque than the Polestar 2 Standard Range.

BMW claims combined average (WLTP) fuel consumption of 9.9-8.5L/100km. Our 415km test comprised a mix of suburban and highway driving and when we stopped to refuel the dash display was showing 10.2L/100km which was line-ball with our own 10.6L/100km figure, calculated from fuel bowser and tripmeter readings.

So, based on our figures, you could expect a realistic driving range of around 780km from its 83-litre tank using standard 91-octane petrol.

Providing power is a sizable 82.56kWh lithium-ion battery pack, using BYD’s signature weight and space-saving ‘Blade’ form-factor, and the more affordable LFP (lithium iron ferrophosphate) chemistry.

On the charging front, the Seal Premium can top up at 150kW on a DC unit (using a Type 2 CCS connector) for a 10-80 per cent charge in roughly 40 minutes, while on AC its a disappointing 7.0kW.

The 7.0kW inverter means it’s hardly worth plugging the Seal in at a slow public charger when you visit the shops, as you’ll only get about 50km of range an hour. It’s for this reason most cars with batteries this size have 11kW inverters.

Unlike the Model 3 or Polestar 2, though, the Seal features a V2L system, allowing you to power household appliances from its Type 2 charging port.

Claimed energy consumption for the Seal is 14.6kWh/100km which is low, and about what we were seeing on test. It’s a little hard to tell because the trip computer only offers total consumption over the entire life of the vehicle, or for the last 50km, but not for a set trip interval. Weird.

It’s supremely comfortable, with front bucket seats that offer powered-adjustment of height, reach and backrest angle along with side bolsters that can tighten their grip of your upper torso.

There’s also two-way lumbar support, that adjusts not only how far it pushes your spine forward but also allows that pressure point to be raised or lowered.

Combined with its power-adjustable leather-rimmed steering wheel, it would be hard not to find a comfortable driving position.

Eyelines to all mirrors are good and over-shoulder blind-spots are minimal. Front and rear occupants can talk without raised voices thanks to low engine, wind and tyre noise at highway speeds.

As you’d expect, it has high build quality and a tangibly solid feel as though it was machined from a single block of steel, from the satisfying thuds of its closing doors to the absence of shudders or rattles on a variety of roads.

It also has two personalities, which can be switched in an instant. In 'Comfort' mode it will happily cruise around city and suburbs as a mild-mannered family car, fulfilling daily duties like work commutes, school drop-offs and pick-ups, supermarket shopping and the like.

However, flick the drive mode to 'Sport Plus' and you awaken, well, if not ‘the ultimate driving machine’ then something close.

Its optimised drivetrain and handling settings feel more like a sports sedan than a family car, which can turn any winding mountain road into an engaging experience.

It has impressive reserves of cornering grip and braking force, combined with sparkling engine response and fast sequential manual-shifting at your fingertips.

It feels impressively agile, with all-round response that belies its 2.0-tonne-plus kerb weight, backed by a symphony of sounds from its sublime in-line six.

I wasn’t expecting the Seal to impress me particularly. After all, it’s in this segment against tough competition, amongst recently updated versions of the Model 3 and Polestar 2, and while the previous BYDs I’ve driven have been a cut above their Chinese contemporaries, they also haven’t done a lot to stand out from the crowd.

Clearly, though, BYD has something to prove with its sporting sedan and the Seal is immediately impressive. The cabin is quiet and refined, the seating position is great it's smooth from take-off.

The steering has an artificial tinge to it removing a bit of feedback from the road, but proves at least quick and accurate at speed, and the handling is superb.

I kept pushing the Seal in my test drive, expecting gnarly characteristics to surface but they didn’t. This sedan grabs onto the road with excellent control and traction at the rear, spurred along by its long wheelbase, and improved tyre choice (Continental rather than the sub-par Chinese rubber worn by the Atto 3 and Dolphin).

While on paper it appears to have at least comparable motor output figures to the Polestar 2 and Model 3 - the Seal Premium doesn’t quite feel as rapid, its electric motor having a more relaxed vibe and responsiveness when you stomp on the go pedal.

This can be tweaked a little by dialling it up to Sport mode, and while it still doesn’t feel quite as breakneck fast as the Model 3, in particular, it’s plenty to be going on with.

The most impressive part of the Seal drive experience, though, is its ride. Ride is a constant problem for EVs as manufacturers go to lengths to tame the additional weight of batteries, but the Seal is the most impressive in its cohort, and by quite a margin.

It’s firm enough to be controlled, but has a lovely soft edge to it, so larger bumps, frequent corrugations, or sharper road imperfections don’t ruin your day.

The Model 3 and Polestar 2, even in their improved forms, are not this good. In a lot of ways the Seal’s suspension tune reminds me of the Mustang Mach-e. It has a soft edge, offset by a bit of secondary jiggle as the car settles, which is its only real blemish.

The Seal has no right being this good. It’s now not just matching its far more established rivals but doing some things significantly better.

The Seal has an extensive list of today’s active safety equipment, including auto emergency braking (front and rear), lane keeping aids, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, traffic sign recognition and driver attention alert.

For the most part, these systems aren’t invasively annoying, which can’t be said for many products from rival automakers.

However, the traffic sign recognition and overspeed warning system conspire to intrude with constant beeping.

Mercifully, and unlike the equivalent system in Hyundai products, it’s a distant beep, but a consistent one nonetheless, as the traffic sign system frequently picks the wrong speed for whatever reason, and then chastises you for going over it.

Also, the adaptive cruise control system can’t hold a candle to the Model 3's. The system in the Seal amounts to the usual sort of adaptive cruise in most other cars, whereas the one in the Model 3 (regardless of how you feel about the brand’s outrageous claims) is properly next-level in its lane keeping and distance controls.

The Seal is equipped with seven airbags and was rated a maximum five ANCAP stars to the 2023 standards.

BMW covers the X5 with a five year/unlimited km warranty and offers several service plans to suit different budgets and requirements.

For example, the 'Service Inclusive Basic' package covers all scheduled services over five years/80,000km for a total of $3450, or an average of $690 per year.

The long-term ownership aspect for a BYD product is still a bit of a mystery as the current crop of cars have only just landed in Australia in the last year or two, but if it offers you any peace of mind, the Seal is covered by a six-year/150,000km warranty with a separate eight-year/160,000km warranty for the battery pack.

In order to avoid having to have a traditional dealer network, BYD has partnered with MyCar to fulfil servicing. Visits to one of these locations is required once every 12 months or 20,000km whichever comes first, and pricing is fixed for the first eight years, working out to an annual average of $299.
