BYD Seal U Review & Prices

The BYD Seal U is a plug-in hybrid SUV with generous standard equipment and an appealing price, but lumpy suspension, underwhelming cabin materials and anonymous styling take off some of the shine.

In that sense, the Seal U is rather like something you discover in the middle aisle of Lidl. It looks useful for the money and has a few surprisingly impressive features, but you’ll soon begin to notice where savings have been made compared with more expensive products.

A Volkswagen Tiguan or Hyundai Tucson feels more upmarket, but either will cost considerably more. In fact, the Seal U is priced closer to a Volkswagen Golf or Toyota Corolla hatchback than many similarly sized SUVs. The excellent Citroen C5 Aircross, however, is available for only a little more.

The MG HS, Geely Starray and Chery Tiggo 7 also follow a similarly value-focused formula, while BYD itself now offers the newer Sealion 5 as another affordable plug-in hybrid SUV.

BYD has proved it can design distinctive cars, such as the sleek Seal saloon, but remove the badges from the forgettable Seal U and it could belong to almost any manufacturer. At least its detailed rear lights and pronounced bonnet give it some visual interest.

The dashboard has a smart design, with neatly incorporated air vents and a 15.6-inch touchscreen taking centre stage. It’s sharp and quick to respond, even though the menu structure takes some learning. Plenty of pricier European cars still offer less convincing infotainment systems.

Space is another strength. Six-foot adults will have no trouble getting comfortable in any seat although particularly tall passengers may find their hair brushing the headlining in the back. The 425-litre boot is wide and deep, but relatively shallow from floor to cover, and its overall capacity trails those of the Seal U’s main alternatives.

Every Seal U uses a 1.5-litre plug-in hybrid system, and it’s arguably the best part of the car. It’s efficient and provides plenty of flexibility on longer journeys. Models with the smaller battery can officially travel 50 miles on electric power, while ‘Comfort’ versions increase that figure to an excellent 78 miles.

Unfortunately, the Seal U struggles to settle around town, shuffling over broken surfaces and rocking through corners and across speed bumps. It becomes calmer on the motorway, but dips and crests still make it feel unsettled at speed. Country roads expose it further, with excessive body lean and very light steering making it difficult to drive with confidence.

Verdict

The BYD Seal U offers exceptional hybrid efficiency, generous passenger space and loads of equipment for sensible money. Its awkward ride, uninspiring handling, small boot and patchy cabin quality stop it feeling truly polished, but buyers prioritising value and electric range over driving enjoyment will find plenty to like here.

For all of its faults, there’s no denying that the BYD is cracking value if you’re most interested in practicality and equipment levels. The entry-level Boost comes fitted with a panoramic sunroof, 19-inch alloy wheels, leatherette interior and Infinity sound system - which means it’s better-appointed than the Citroen C5 Aircross and even the Volkswagen Tiguan, on paper.

The Comfort model is a couple thousand pounds more expensive but comes with a larger 26.6kWh battery (versus 18.3kWh in the Boost) which gives it more electric range. The top-spec Design model features all-wheel drive and more power, but strangely it’s fitted with the smaller battery from the Comfort model - yet costs £40,000.

The hybrid engine is impressively quiet and refined, but otherwise the BYD Seal U is disappointing to drive

In town

The BYD Seal U is easy to drive around town. The suspension is incredibly soft and the steering is light, so it’s little effort to nip about in traffic. However, that soft suspension means that the car never really settles and feels like it’s always wobbling around over undulations in the road. If you hit a pothole or a small speed bump it sends a shudder through the cabin.

Fortunately the hybrid system is excellent, and the Seal U drives like an electric car. If you've got a good amount of charge you’ll barely use the petrol engine, and when it does kick in, you can hardly hear a thing. Forward visibility is good, but the view over your shoulder is poor. At least front and rear parking sensors and a 360-degree camera making it easier to park in a tight spot.

On the motorway

The cabin is pretty hushed on the motorway. A bit of tyre noise is noticeable, it's not too intrusive, and when the petrol engine is called upon it is really quiet. The suspension is less annoying at higher speeds, but you still get that odd sensation that the car takes a while to settle after undulations in the road.

The steering gets a bit heavier at higher speeds, but it feels unnatural which can make smooth lane changes a bit of a challenge. Standard-fit adaptive cruise control maintains your speed and distance to the car in front, yet even this has its issues. The adaptive cruise control tends to pulse the power on and off, making for a sickness-inducing experience.

On a twisty road

If you want to enjoy taking the scenic route home on a twisty, then this is one SUV to avoid. The steering is so light that you have no idea what the front wheels are doing, meaning it’s difficult to judge where you are on the road, how much steering input is required, and how much grip you have. The body also leans a lot in corners, which is really unnerving. The Ford Kuga is considerably more expensive, but light years ahead in terms of driver enjoyment.

Cabin storage isn’t amazing, but the BYD Seal U has really roomy back seats and a decent-sized boot

The BYD Seal U is pretty roomy for those in the front, and there’s a decent amount of adjustability in the driver’s seat and steering wheel to get a comfortable driving position.

Storage is fine but it’s about the minimum you would expect – the door bins are okay but you’ll struggle to fit a big bottle inside, and the glovebox isn’t huge. The cubby under the armrest is really deep though, making it a great place to hide things out of sight. You get two cup holders with grips on the edge so your drink doesn’t fall over, and a pair of wireless phone charging pads beneath the screen.

Space in the back seats

Rear seat space is similarly impressive. If you’re over six -feet tall you might start to feel your head is brushing the headlining, but it’s fine for most, and even your lankiest friends will have no complaints about kneeroom. The upside is that you'll easily fit even the bulkiest of child seats in the back - with ISOFIX mounting points in the outer seats. As with the front, though, storage isn’t fantastic, thanks to small door bins and not a lot else.

Boot space

At 425 litres the Seal U’s boot is adequate. Similarly priced alternatives such as the Kia Niro (358 litres) generally have less space, though other bargain SUVs have more - such as the MG HS at 507 litres. The plug-in hybrid Hyundai Tucson gets a 558-litre boot and the Volkswagen Tiguan has a huge 652 litres on offer, but are more expensive.

The Seal U’s boot is a square space that’s easy to pack and there are small cubbies at each side to give you somewhere to hold smaller items, but no underfloor cable storage. You have to fold the seats from the cabin, at which point there’s 1,440 litres of space available - but a big lip makes it difficult to push long, heavy items through.

The infotainment system is excellent and most materials are decent for the price, but the design is pretty plain and cheap plastics are never far away

First impressions are pretty good inside. Sure, the design is pretty plain, with a simple panel across the centre of the dashboard that flows down in the central area between the seats, but the materials all look good quality. There aren’t many squishy plastics, but for the price it’s more than adequate quality inside.

That 15.6-inch central touchscreen is more than adequate. The graphics are sharp and it responds instantly to your touch. It’s not the most intuitive menu system to navigate around, but Apple CarPlay and Android Auto work seamlessly. You can also rotate the screen if you prefer it to be portrait-orientated, which is fun but gimmicky.

The BYD Seal uses a 1.5-litre petrol engine with a single electric motor in the Boost and Comfort trims, or two motors in the Design trim for all-wheel drive.

In Boost and Design trims, the motors are powered by an 18.2kWh battery that offers a range of up to 50 miles for Boost models or 43 miles in Design spec. If you want maximum choosing the Comfort model, because that has a 26.6kWh battery that increases the range to a hugely impressive 77 miles.

CO2 emissions figures are incredibly low, meaning cheap Benefit-in-Kind payments for company car drivers. For private buyers, even the most expensive model only just falls below £40,000, which means you don’t have to pay the extra road tax in years two to six for cars that cost over that threshold.

A maximum of just 18kW on public DC plugs means it’s not worth going to pricey fast chargers when out and about. However, a maximum AC rate of 11kW is useful if you have access to chargers that can achieve that.

BYD Seal U Euro NCAP score (2023):
Adult occupant: 90%
Child occupant: 86%
Vulnerable road users: 83%
Safety assist: 77%

The BYD Seal U scored the maximum five stars in Euro NCAP safety testing, with impressive ratings across the board. It achieved 90% for adult occupant protection, 86% for child occupants, 83% for vulnerable road users, and 77% for its safety assist systems.

You get loads of assistance kit as standard including adaptive cruise control, lane-keep assist, alerts for traffic passing in front or behind the car when manoeuvring and front and rear collision warning. You get the usual ISOFIX points in the outer rear seats, but there’s also another in the front passenger seat.

BYD came 16th out of 30 brands in the 2026 Driver Power owner satisfaction survey, which isn't a stunning result, but impressive given the brand's relative newness.

You do get an excellent six-year warranty though, with a limit of 93,750 miles if that comes up first. The battery gets a separate eight-year/125,000-mile warranty that guarantees it will retain 70% of its original capacity in that time.

Those are impressive figures, but still beaten by Toyota and Lexus which offer ten year/100,000 miles warranties with regular dealer servicing.

We spent six months living with the BYD Seal U to test its capabilities as a daily driver, giving us a thorough chance to assess everything from efficiency to real-world practicality, and any little tricks or quirks you may love or ultimately hate.

What we liked

We were left impressed with the BYD Seal U’s hybrid engine. Although it lacks a little in performance, its quiet operation and high amount of time spent in electric-only mode had us charmed, while an average fuel economy return of around 40mpg was welcome considering the size of this SUV

Another weapon in the Seal U’s arsenal is its clever tech. The high-definition surround-view camera made parking a breeze and has come in handy while dealing with tight London streets littered with width restrictors. Standard-fit adaptive cruise control takes some of the stress out of longer journeys, too.

We were really able to test the practicality of the SUV’s interior and boot, too, with the arrival of associate producer James Drujon’s firstborn son. Easy-access ISOFIX points came in handy, as did the numerous cubby holes to keep various bits and bobs in.

What we didn’t like

Although the high-def camera was a plus point of the BYD Seal U, its parking sensors proved repeatedly irritating. They show your supposed distance to an object on screen, which in theory would be incredibly useful, but more often than not, it proved inaccurate and untrustworthy.

In the pursuit of a sportier style, the rear end of the Seal U has a slight slope to it, which doesn’t help visibility and hinders boot space, two things we found grating by the end of our time with the car.

The overall driving experience left something to be desired, too. Although it doesn’t need to handle like a sports car, more composure and refinement in the way it drives would be welcome.

Our final thoughts

For its price, the BYD Seal U is an impressive package. Its strengths lie in its rear space, refined hybrid engine and levels of technology on offer.

It could be a bit better to drive, but that’s not often a concern with a car of this size and nature. Boot space is, however, and you’d be better served with something like a Skoda Karoq for sheer practicality.
