BYD Seal vs GWM Tank 300

What's the difference?

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.

There’s a lot to like here. The GWM Tank 300 in any of its forms is a competent vehicle from the helm and backs up its off-road claims with real ability. The ride quality, in particular, is a highlight, and it’s a good size for couples or young families. Its value for money is also quite brilliant.

Add this plug-in hybrid driveline to the mix and the performance is quite astounding, while the petrol engine and EV potential have arrived at a critical point in history where such things carry more weight than ever before. It remains to be seen what happens globally and what effect that has on fuel prices, specifically the price gap between petrol and diesel. There’s also the question of what happens electronically when you dunk the Tank into Nolan’s Brook on the track to Cape York. But for now, this is a car whose time appears to have come.

But while the overall concept deserves praise, there’s still some work required in terms of the way the car drives and in its attempts at keeping its occupants safe. The calibration of both the throttle response and some of the driver aids is, frankly, in need of some final polish. And though it sounds odd, the Tank 300 would be a better thing to live with if GWM ditched the contentious driver aids and took the points hit on its ANCAP rating. Even better would be to stick with the tech but refine it to the point where it works in the background and not as an irritant.

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.

Derivative is a strong word, but from most angles there’s a little bit of something else in the Tank 300’s exterior. We can easily see a bit of Suzuki Jimny in profile, and a dash of new Ford Bronco in the lights and grille. And if you squint there’s a blob of Jeep Wrangler in the wheel-arch extensions.

Which should mean it’s just a mash-up. Yet somehow, it isn’t, and the Tank has its own vibe.

Inside, that vibe suddenly becomes a bit overdone, and the plastic garnish above the glove box, in particular, looks like it will date pretty quickly (if it hasn't already). There's also a lot going on in here; this is a busy place and even the gear selector looks like a prop form the Star Wars franchise.

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.

While GWM is by no means the worst offender, we still reckon the Tank’s interior would be better without such a degree of reliance of touchscreens and menu-driven functionality. While it’s obvious that there’s a lot going on in the cabin, it still seems odd that important functions such as shifting from conventional hybrid mode to EV mode would require a dive through the on-screen menus when a simple switch would be faster, easier and simpler.

And even when GWM has provided switches, the end result is muddy. Take the volume controls for an example. There’s no central volume knob accessible by both front seat occupants, so you rely on the steering wheel mounted up and down buttons to change the volume. Except they’re not marked as volume controls in any specific way. Okay, if you know, you know. But if you don’t know, you’ve just missed the news headlines.

Overall, it's disappointing. And I resent the fact that GWM (or anybody else) thinks it’s okay for me to have to learn to operate a car all over again. The dashboard is also full of tiny symbols and lettering making things difficult to decipher if you normally wear glasses to read, but not to drive.

We’ll take issue with the indicator stalk, too, which has an indistinct feel when trying to discern whether you turned the indicators on for an intersection, or just tipped them on for three flashes for a lane change. And if you have accidentally gone too far and they’re still flashing away merrily after the lane change, turning them off manually is a lottery that might see you succeed, or mistakenly turn on the other side flashers.

The rest is better with proper buttons for the various off-road drive modes, diff locks and hill holder. There’s even an analogue clock for some real nostalgia. You’ll also find a single USB-A and USB-C charge port in the dash, and a pair of cupholders buried deep in the centre console which also has a lid and sliding drawer.

It’s obvious that this is a smaller vehicle than some, and the four-door layout dictates shorter doors. But that doesn’t alter the fact that the driver’s seat slides back a few centimetres every time you shut the car down. The trouble with that if you’re tall, is that the seat is now tucked back in behind the B-pillar, meaning you have to climb out and around it to exit the car. Perhaps you can switch off this slide-back function, but I didn’t have the spare hour to troll through the menus to do so. Oh, and there should be a driver’s grab handle on the A-pillar, too. There isn’t.

The rear seat is better with an adjustable backrest that provides proper comfort, and leg and knee room that hides the 300’s smaller dimensions well. There’s lots of glass and light and a pair of USB charge points. You also get a pair of rear reading lights and central vents, but no climate controls.

Even the cargo area is a decent size with the five seats in place (360 litres, up to 1520L with 60/40 rear seats lowered) but the under-floor storage space has been consumed by the hybrid battery, meaning the jack and tools and charging cable live in the cargo area and the spare tyre is bolted to the tailgate.

The single-piece tailgate is hinged at the side, and needs a fair bit of real estate to be swung open fully.

The Tank features vehicle-to-load capability, too, which means you can operate your power tools using the vehicle as the power source, and there’s a 220-volt socket in the luggage area to do just that. But when camping, too, this feature can also power induction cookers, microwaves, and all the other stuff you probably should have left at home. And if the hybrid battery runs out of charge, the Tank can run its petrol engine to act as a generator (your camping neighbours are going to love that).

The real gadget freaks out there can also download the Tank app which allows you to operate functions such as power windows, climate control, seat heaters, central locking and check your charging status all from the comfort of your smartphone. You can also use this functionality to flash the hazard lights to help spot your Tank from everybody else’s in the carpark.

The Tank 300 PHEV is available in two trim levels, starting with the Lux at $55,990 drive-away. That gets you 18-inch alloy wheels, roof rails and side steps and, perhaps a little surprisingly, a sunroof.

There’s also power folding mirrors, keyless entry and start, paddle shifters, adaptive cruise-control and a rear differential lock.

Inside, there are leather accents for the seats, a pair of 12.3-inch multimedia, ambient lighting, digital radio, wireless connectivity, wireless phone charging, wireless Apple CarPlay and Android Auto, automatic headlights, full LED lighting, and dual-zone climate control. That’s quite a bit of gear for the money.

But throw another four grand on the sales rep's desk, and you into the Ultra grade which adds heated, cooled and massaging front seats, eight-way power adjustment for the driver’s chair, Nappa leather inserts, underbody protection, a front differential lock and no less than 64 colour choices for the expanded ambient lighting package.

Fundamentally, then, your extra $4000 is buying the clever front seats and front diff lock, but that’s easily worth the money anyhow. That said, the entry-level variant is one of the better equipped at that price-point, so either way, you won’t be slumming it.

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.

The Tank’s plug-in driveline, starts with a petrol engine measuring 2.0-litres and contributing 180kW to the overall picture. But then there’s a single electric motor, sandwiched between the petrol engine and the nine-speed transmission. That means the Tank is still a mechanical four-wheel-drive platform, and when both powerplants are singing together, there’s an eye-opening 300kW and 750Nm of torque on tap.

The four-wheel-drive system operates as a rear-wheel drive on dry bitumen, and there’s the usual 4WD high range and 4WD low range. What there isn’t, is a 4WD-auto setting that allows you to use four-wheel drive in the dry on a paved road. That sounds minor, but for towing in particular, having all four wheels doing the driving is a major safety bonus.

All Tank 300s get a rear differential lock, but this version, the Ultra, also gets a locking front diff as well. Typically, the Tank also features a range of driving modes (no less than nine of them!) for the four-wheel-drive function, tailoring throttle, transmission and differential response according to the type of terrain being covered.

The Tank 300 is built the old fashioned way with a ladder-chassis upon which the body is bolted, and it still uses a live rear axle, too. But the front suspension is independent and the GWM uses coil springs rather than old-school leaf springs for much better ride quality.

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.

The headline number here is GWM’s official fuel consumption number of just 1.9 litres per 100km. Or it would be if it had anything to do with the real world. As it is, nobody is going to achieve that, and our mix of urban running netted an average of about 11.0 litres per 100km, with that dropping to 8.5 litres per 100km in country conditions.

The truth is, your consumption in this vehicle can go from zero to, say, 12 litres per 100km depending on how and where you drive and how much battery charge you have available.

Speaking of charging, the Tank 300 can use a commercial fast charger to absorb voltage at a rate of 50kW. At that rate, it can go from 30 to 80 per cent charged in about 24 minutes. A wall box (GWM offers one as a factory option) can take the 37.1kWh battery from 15 per cent to fully charged in 6.5 hours. And, of course, you can also charge the Tank from a domestic wall socket in a claimed 14.4 hours. We managed to add about 6km worth of charge per hour on such an outlet during our time with the car.

As far as range goes, GWM reckons there’s 115km (NEDC) of EV-only range, while starting a journey with a fully charged battery and a full 70-litre fuel tank should see you covering somewhere between 900 and 950km between top ups.

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.

GWM claims a 0-100km/h acceleration time of just 6.3 seconds for the Tank 300 PHEV, and that’s impressive. There are two caveats here. The first is that you need at least 40 per cent battery charge on board to extract maximum thrust. And, secondly, even in those circumstances, the Tank never feels that brisk. It’s more effortless than genuinely rapid, although the torque up hills is genuinely impressive.

There’s no getting around the refinement inherent in using volts for some of the time. And when the petrol engine does chime in, it’s all but imperceptible. You’ll eventually hear the engine if you wring it right out, but even then, vibrations are minimal.

All in all, the Tank’s relatively compact dimensions work in its favour in an urban setting, and the range of camera views (including an off-road one showing you the obstacles you’re about to encounter) make parking a lot easier than it might have been. Only a high degree of distortion in the birds-eye-view camera mode takes a bit of getting used to.

On the move the ride quality is quite exceptional, and those coil springs really do make a difference. Even the usual council speed bumps don’t bother the Tank and the short wheelbase pitching we’ve seen in some similar vehicles just never emerges. Well chosen damper rates help, too, and there has been some Australian input into the way the Tank handles. It shows.

Steering, too, feels light and natural, although the almost constant fidgeting at the helm by the lane-keeping assistance program is annoying. And switching it off is not only a multi-button job, it needs to be done every time you start the vehicle.

Far and away the biggest hurdle in living with the Tank, however, is a throttle calibration that is way off the mark. Pressing the accelerator pedal initially doesn’t seem to do much at all, and then suddenly, the power comes in and you discover you’ve input too much throttle as the Tank surges away down the road, threatening to actually spin its tyres if there’s any gravel about. But not until that initial hesitation has caused the driver behind you to wonder aloud (I can lip-read) if you’re ever going to move at all. This needs to be fixed as a running change.

The all-important off-road driving experience is pretty sharp and the Tank 300 is a genuine competitor in this discipline. It’s extremely stable and capable on unsealed roads and tracks and the front and rear diff locks make it a proper adventurer’s rig.

It’s relatively demure dimensions also mean that it fits down the tracks and trails that have been created by decades of vehicles of a similar size, unlike some of the bigger new off-roaders we’re seeing that simply don’t fit in to the terrain so neatly.

Ultimately, the Tank’s stock tyres will be the limiting factor, but there are plenty of alternatives out there for a bit more off-road bite.

The Tank has a strong safety story to tell, especially on paper.

Regardless of what specification you buy, you’ll get seven airbags including full-length side-curtain bags and a centre airbag to reduce head injuries in a side-impact crash.

There are rear parking sensors, a range of camera angles including an overhead view, tyre-pressure monitoring, Isofix child-restraint mounts, and the usual driver aids including autonomous emergency braking, rear cross-traffic alert and braking, blind-spot monitoring, traffic-sign recognition and rear collision warning.

But away from the brochure, features such as the lane-keeping assistance and the driver-fatigue monitor need work on their calibration. GWM is by no means on its own here, but it’s a fact that some other makers do a better job of making this tech transparent and vastly less intrusive.

The original Tank 300 launched in Australia in 2022 scored five safety stars in ANCAP testing, and that rating has been carried over to this car.

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.

GWM offers a seven year/unlimited kilometre warranty on the Tank 300, as well as eight years of cover for the hybrid battery (also with no kilometre limit). There’s also seven years of roadside assistance thrown in, too.

Capped-price servicing is available for the first seven years, with the first service due at 12 months or 10,000km and subsequent services every 12 months of 15,000km after that. Prices for each service (in order) are: $320, $460, $460, $685, $685, $1075, and $370.

GWM has a network of 123 new-car dealerships able to handle servicing, and the company tells us that regional centres have not been forgotten.
