BYD’s UK expansion has been relentless. In just a few years, the Chinese brand has gone from curiosity to common sight, helped by aggressive pricing and a growing appetite for electrified cars that don’t feel like luxury purchases.
Last year, it sold more than 50,000 cars in the UK — that’s more than Citroen, Honda, Mazda, or Tesla.
The Sealion 5 DM-i is the latest expression of that strategy. It’s a mid-size plug-in hybrid SUV, priced from £29,995, and aimed squarely at buyers who might otherwise be shopping for a petrol family SUV rather than a PHEV. In other words, it’s designed to tempt people into electrification without asking them to change how they live or, crucially, how much they spend.
Having driven it this week, the Sealion 5 feels like a car with a clear purpose. Whether it fully delivers on that purpose is a little more complicated.
All-too familiar design
In the metal, the BYD Sealion 5 is unlikely to provoke strong reactions. Or any reaction. The styling is clean but generic, with nothing that’s either bold or offensive. If you removed the badges, it would be mistaken for any number of modern SUVs from China, Korea or Europe.
Size-wise, it’s firmly family-friendly. There’s plenty of space up front and in the rear, a flat floor in the back that makes carrying three adults feasible, and a 463-litre boot that’s perfectly adequate for everyday use. It doesn’t feel especially clever or inventive inside, but it does feel usefully big, and for many buyers, that matters far more than visual flair.
The rest of the interior follows a familiar BYD template. There’s a large 12.8-inch central touchscreen (although it no longer rotates, apparently not to save money but because drivers just weren’t using it on other BYD models), a digital driver display, and a mix of soft-touch materials and artificial leather upholstery that gives the cabin a slightly more premium feel than the price tag might suggest.
There are also some welcome physical buttons around the centre console — something BYD hasn’t always prioritised — though too many everyday functions still require a dive into touchscreen menus. Seats are on the firm side, and the driving position won’t suit everyone, particularly taller drivers who may wish for a little more adjustment. Even at exactly average height, I found the seat only just went back far enough.
Rear passengers, however, are well catered for, with generous legroom, good headroom and a pair of USB ports. As a place to spend time, the Sealion 5 feels perfectly pleasant, just not especially memorable.
The DM-i hybrid system
Power comes from BYD’s DM-i plug-in hybrid system, which pairs a 1.5-litre petrol engine with an electric motor for a combined output of around 210hp. In normal driving, it behaves much more like an electric car than a conventional hybrid, pulling away smoothly and quietly with the petrol engine largely kept in reserve.
Two battery options are available. The Comfort model uses a smaller pack with a claimed electric-only range of around 38 miles, while the Design version increases that to roughly 53 miles. Either should be enough to cover most daily journeys without using petrol, provided you plug in regularly.
However, charging is limited to 3.3kW AC, which is slow by modern standards. Even someone with a home charger will see their rate limited from the 7.4kW expected, although with just 13 or 18kWh to top up, it’s workable for overnight home charging. It’s another reminder that this is a car built to a price, though.
On the road: competent, but unsettled
Driven on UK roads, the Sealion 5 quickly reveals its character and its main weakness. The biggest issue is ride quality. The suspension struggles to keep up with the car’s movements over imperfect surfaces, particularly on Britain’s patchy roads.
Longer, rolling undulations leave it gently lolling from one movement to the next, while shorter, sharper bumps and cracks thump through the structure more harshly than you’d expect from a family-focused SUV.
It’s not entirely uncomfortable, but it lacks composure, and you’re often aware that the car hasn’t fully settled before the next input arrives. Over time, that becomes tiring.
Beyond that, the driving experience is entirely benign. The Sealion 5 feels stable and predictable, with decent balance and no nasty surprises, but nothing to encourage enthusiastic driving. Steering is light and largely devoid of feel, body control is fine rather than engaging, and while grip levels are respectable, the car never invites you to explore them.
Performance is adequate. Slightly amusingly, BYD has fitted a built-in 0–62mph timer — an odd feature in a car so resolutely sensible — but it does at least appear honest. A recorded 7.8 seconds was just a tenth shy of the official figure, even if the presence of the timer itself feels faintly absurd.
Strong value, but with strong competition
Price remains the Sealion 5’s strongest selling point. At under £30,000, it undercuts many established plug-in hybrid rivals by a meaningful margin, offering a lot of space and equipment for the money.
However, it sits just £5 above the Geely Starray EM-i, a similarly sized and positioned family-friendly PHEV that offers claimed electric-only ranges of up to 84 miles depending on battery choice. That slightly blunts BYD’s pricing advantage.
Against more traditional rivals like the Hyundai Tucson or Ford Kuga in plug-in hybrid form, the Sealion 5 still looks like good value, but it doesn’t feel as uniquely compelling as it might have done even a year ago.
BYD Sealion 5 DM-i: The Average Joes first drive verdict
The BYD Sealion 5 DM-i is a rational, sensibly priced plug-in hybrid SUV that does most things reasonably well, and very few things brilliantly.
Its strengths are obvious: usable electric range, generous space, strong standard equipment and a price designed to tempt buyers out of petrol cars rather than premium PHEVs. Its weaknesses are just as clear: unsettled ride quality, an unrefined petrol engine when it’s working hard, and a driving experience that’s competent but forgettable.
If you’re looking for the most polished or enjoyable SUV in this class, there are better options elsewhere. But if value, everyday usability, and low-emission running matter more than finesse, the Sealion 5 will make a lot of sense to a lot of buyers.
Just don’t expect it to charm you. It’s here to make the numbers work.
