BYD Dolphin review
The BYD Dolphin is the car you buy when you've done the spreadsheet and stopped caring what the neighbors drive. It's a compact Chinese hatch with a Blade battery, a heat pump, vehicle-to-load, and a 5-star Euro NCAP rating — and a personality best described as a very diligent appliance that will not stop beeping at you.
Let's start with the beeping, because every owner does. The Dolphin's driver-assistance systems are the most complained-about feature in every source I found: traffic-sign recognition that nags, a driver monitor that scolds you for yawning, lane assist that owners describe as "vicious." The universal owner ritual is switching half of it off before every single drive — through an infotainment system with icons so small that one tester said adjusting the temperature "requires the dexterity of a heart surgeon." BYD keeps tweaking the ADAS with over-the-air updates, but as of 2026 the nannies are still the car's defining character flaw. If you test-drive one, do what the owners do: drive it first with everything on, then ask the salesperson to show you how to kill it all. You'll use that menu daily.
Underneath the nagging, though, the fundamentals are genuinely strong. The Blade LFP battery is the real deal — cobalt-free, famously abuse-tolerant, and showing no degradation drama in owner reports. Real-world efficiency regularly beats the official 15.9 kWh/100 km figure. The seats get unprompted love ("extremely comfortable," says a six-month Australian owner), the ride is compliant, the cabin is roomier than the footprint suggests, and the kit list embarrasses cars costing half as much again: 360° camera, V2L that powered one owner's fridge through an eight-hour blackout, rotating touchscreen. It's the sort of car where the spec sheet reads like a prank and then the car actually delivers.
The honest negatives, beyond the beeping: 88 kW DC charging is merely okay and AC charging is slow in some markets; there's no spare wheel, just repair goop; the factory LingLong tyres get called "substandard" by owners; the yearly service schedule is, in one owner's words, "ridiculous... for an EV"; motorway wind noise suggests insulation savings; the front wheels spin if you floor the 204 hp through them; and there's a new-plastic smell that one reviewer called "sickening." None of these are dealbreakers at the right price. All of them are reasons not to pay the wrong price.
Reliability-wise, the Dolphin is the cleanest sheet in this cluster. No drivetrain or battery failure waves. The one serious mark: in September 2024 BYD recalled 96,714 Dolphin and Yuan Plus cars in China — its largest recall ever at the time — over a steering-column controller defect that could cause short circuits and fires. No incidents were reported and the fix is insulation pads fitted free, but the build window (February to December 2023) overlaps the first European cars. If you're buying a 2023, check the recall status before anything else. Otherwise, the warranty is generous — six years basic, eight on the battery in the UK — and the dealer network, while young in Europe, hasn't generated the horror stories you'll find attached to some rivals in this roundup.
The social scene is telling in its quietness. There are no Dolphin war diaries, no viral vents, no cult. Facebook owner groups are thin and mostly Canadian brand chatter (the Dolphin isn't even sold in Canada). Owners read as pragmatic first-time EV buyers who ran the numbers: they praise the efficiency and the kit, they disable the nannies, they get on with their lives. The depreciation conversation is the liveliest topic — because it's brutal. A 2024 Comfort that cost over £30k new is £15k–£17.5k used in the UK. That's 40% gone in two years, which stings if you bought new and delights if you didn't.
Value call, and it's simple. The nearest rivals are the MG4 (sharper to drive, worse interior, similar depreciation cliff), the VW ID.3 (nicer badge, less kit, more money), and the Renault 5 (more charm, less space). Against all three, a used Dolphin is the rationalist's pick — maximum battery and kit per pound. The sweet-spot buy is a 2024 Comfort with the 60.48 kWh battery: big battery, post-recall-batch build, all the kit, at £15k–17.5k. Skip 2023 cars from the February–December 2023 build window unless the steering-controller recall is documented as done — it's a free fix, but you don't want to be the one discovering it wasn't. And skip buying new at £30,230+: BYD killed the cheap Active and Boost trims, so the configurator no longer sells the cheap Dolphin. The used market does.
The honest tradeoff: it's the best EV appliance money can buy at the used price, and it will beep at you about it. Owners who made peace with the off-switch seem genuinely happy. The spreadsheet says buy the 2024. The spreadsheet is right.
