From £18,6408

In China this miniature hatchback costs £7500, but can BYD’s export-market value EV cut it here?

The BYD Seagull is the car that made waves when it arrived in its maker’s domestic market in 2023 as one of the very cheapest EVs in the world.

As far as British and European buyers are concerned, the ‘export’ version will be known as the BYD Dolphin Surf – but it is nonetheless essentially the same car, and it stands ready to add to the burgeoning value EV ranks.

In South America, the Dolphin Surf is called the Dolphin Mini. You can guess why BYD didn't try to use that suffix over here.

It brings with it BYD’s expertise on battery and motor technology and an entry price that undercuts most of its European competitors. So, can China’s renowned global ‘new energy’ specialist use all of that experience to do more with less?

DESIGN & STYLING

BYD Dolphin Surf RT 2025 Review 25 C pillar detail 0108

At 3990mm long, the Dolphin Surf is sized like the Citroën ë-C3 and Renault 5. What muddies the water – although not in any bad way as far as its buyers will be concerned – is the car’s sub-£19k entry price, which positions it just as close to A- and B-segment EVs such as the Dacia Spring and Leapmotor T03

It comes with a choice of two lithium-iron-phosphate (LFP) batteries: 30kWh in the case of the Active base model or 43.2kWh in either of the others. Both are BYD’s own Blade pack, which it says add torsional rigidity to the chassis under the cabin and are among the safest and most impact-resistant designs on the market.

I quite like the Surf’s obviously avian stare, but the styling from the B-pillar back is a bit of a hotchpotch. Neither the upward-kinked beltline nor the fussy C-pillar detailing seem to add much.

A choice of either of two permanent synchronous magnet motors, with 87bhp or 154bhp, sits transversely on the front axle, drives the front wheels and is packaged in what is described as an efficient ‘eight-in-one’ unit (incorporating the motor, transmission, charger, current inverter and all of the key battery, motor and vehicle control units).

We tested the mid-range Boost model, which combines the less powerful motor with the bigger battery for the greatest-available WLTP lab-test range, at 200 miles.

Suspension is class-typical: struts at the front and a torsion beam at the rear. Braking is via steel discs at all four corners. And kerb weight is, by EV standards, fairly modest: 1385kg on the scales (ë-C3, 1479kg; 5 Comfort Range, 1461kg).

INTERIOR

BYD Dolphin Surf RT 2025 Review 25 dash 0096

The Surf is both narrower and taller in the body than the average supermini. Interestingly, it has slightly less head room than the ë-C3, but leg room enough to beat it in both rows – and enough of each for a couple of adults of at least average height to travel happily in the back seats.

Space for the driver is more than adequate: our mid-spec test car had fully electric seat adjustment and plenty of scope to adjust the steering column. A 20mm outboard offset to the position of that column, however, obliges you to sit slightly towards the outboard side of the driver’s seat, which compromises comfort a little.

The physical switches adjacent to the drive selector have a strange action: you flick the buttons up or down rather than pushing in. The selection of functions here is a bit odd also: two of the six buttons control drive mode, but there's nothing here for either ADAS or regen control.

More widely, the Surf’s cabin seems to be particularly well-appointed and well equipped for this price point. There’s a small but useful digital instrument display, while BYD’s familiar rotating, free-standing multimedia display sits on the centre of the fascia.

Drive and audio controls are arranged in a row of rotating knobs and buttons just below the multimedia screen. The action of some of these feels unintuitive at first, but their placement is convenient enough. There are notes of solidity about their tactile feel, too, which matches that of the car’s window switches, door releases and other fixtures.

Just as it has with its other recent model introductions, BYD is delivering plenty of tangible, perceptible material quality with the Surf’s interior – perhaps even more so in this segment than elsewhere. That should stand it in good stead with buyers who don’t see why a £20,000 new car need look or feel cheap.

Multimedia - 3.5 stars

BYD’s 10.1in rotating touchscreen infotainment system is standard fit here, even on an £18k Active model. And that swivelling function isn’t solely for wow factor: if you like a ‘bird’s eye view’ style of sat-nav mapping, for instance, a portrait-oriented screen makes a lot of sense.

Just know that as soon as you switch to the system’s smartphone mirroring mode (wireless Apple CarPlay and Android Auto come as standard; wireless charging only on top-tier models), the screen automatically motors back to its landscape orientation. Also note that BYD’s factory sat-nav isn’t really good enough to make you inclined to use it over your smartphone’s Google Maps app.

There’s no physical cursor controller with which to navigate the display, and while you can configure the content of the screen’s bottom shortcut bar, it only displays icons at a very fiddly, annoyingly small size. The system’s layout is otherwise a little protracted, but it’s usable enough with practice.

ENGINES & PERFORMANCE

The Dolphin Surf as we tested it isn’t a particularly energetic or fun little EV – but BYD has an answer to that. Go for the slightly unintuitively titled Comfort model instead and you get more power than any rival for similar money. The Boost model, by contrast, is a compromise of performance against efficiency and range – but a worthwhile one, in our view.

It’s certainly not especially slow, at least not by the broader standards of the value supermini class. A 12.0sec 0-60mph showing looks sedate on paper, but there’s enough oomph and responsiveness here for the car to feel fairly zippy up to and around urban speeds, and for it to cope out of town well enough up to about 60mph. The car does seem a little out of its depth beyond that speed, but not by enough to make it feel vulnerable or to cause alarm. In short, it’s fairly basic transport – but of an agreeable enough kind.

Brake energy regen control is a bit simplistic: you simply choose between ‘standard’ and ‘high’ settings via a touchscreen display menu that’s not quite accessible enough to adjust it at will. Quite why the car needs two physical buttons to adjust its drive mode while it gets none for regen control seems strange.

The car’s 16in wheels and fairly skinny Hankook tyres create enough traction to convey its performance in the dry, and they’re electronically well governed in the wet. Outright stopping power is a little meek but acceptable enough.

RIDE & HANDLING

BYD Dolphin Surf RT 2025 Review 25 front corner 0115

There may be only marginally more to be interested about by the Dolphin Surf’s chassis than its powertrain. But, driver ‘assistance’ systems notwithstanding (we will come to that shortly), there’s also little here about which to be annoyed or disappointed. As small, keenly priced electric cars go, this one hits a perfectly competent and consistent dynamic standard.

The car’s grip level may be modest, but it doesn’t seem to run up against the limits of it very often. While the steering is a little numb-feeling and quite gently geared, there is some balance to the car’s handling, along with the kind of agility that small cars almost always conjure as a default, plus an affable simplicity of dynamic character that isn’t troubled by corrupting levels of power and torque or an excess of weight or size.

Out of town, the Surf’s ride is typically a shade more settled and better-isolated than in some bargain-bucket superminis. Find a complex road surface and the car will pitch and bumble fore and a little on its springs, while the secondary ride becomes just a little busy and castor-like as it pings and fusses over a broken road.

Generally, though, this car does a very competent job of town motoring while avoiding making a meal out of quicker miles – which is about all you can reasonably expect of it.

Assisted Driving - 2.5 stars

The Dolphin Surf comes with six airbags and a suite of ADAS functions as standard across the range, among which is adaptive cruise control with lane keeping assistance. Are they worth having? Some, perhaps - but not all.

The driver monitoring system is quick to temper and nannyish; the AEB and lane departure warning systems are less intrusive. But the ‘intelligent’ cruise control really is quite poor: it battles with you for fine control of lane positioning on a motorway, and it’s slow and sudden to regulate speed to that of traffic ahead.

More annoying still is that BYD doesn’t even see fit to put deactivation controls for all of these systems on the same touchscreen menu page, so your ‘pre-flight check’ routine is longer and more convoluted than it need be.

MPG & RUNNING COSTS

BYD Dolphin Surf RT 2025 Review 25 front corner 0122

The Dolphin Surf’s UK entry price of £18,650 gives it a clear advantage over European rivals. Even in as-tested mid-spec trim it’s compelling value, especially given the generous tally of standard equipment.

While the car doesn’t have the biggest battery capacity in its class, it is efficient. The Boost model uses the same motor as the Comfort but in restricted form, so it can provide 87bhp yet regenerate at up to 121bhp. That may help to explain how our test car recorded 3.9mpkWh in our motorway touring efficiency test and 5.6mpkWh on our ‘everyday’ route, while the ë-C3 managed only 2.8 and 4.0mpkWh.

The drive computer relays plenty of useful info, but lacks a conventional trip meter for efficiency. Instead it gives a rolling ‘kWh/50 mile’ average. This can be ‘cleared’ but not properly reset - so you can make the number disappear momentarily, only to reappear exactly as it was previously. Moreover, our testing would suggest it's actually an average over 50km, not 50 miles as stated. Does that matter? Not a great deal - but a proper, resettable efficiency indication would be preferable, and can't be difficult to code for.

The difference that makes turns the Dolphin Surf into a car capable of more than 160 motorway miles per charge, or one that could cover close to 250 miles in exclusively urban use. Impressive for the price. 

Verified DC rapid charging performance was less impressive but far from deal-breaking; most encouraging, interestingly, for users who will regularly rapid-charge to 100%, with the car maintaining better charging speeds than rivals at higher states of charge.

VERDICT

BYD Dolphin Surf RT 2025 Review 25 static 0113

The BYD Dolphin Surf is a good recruit to the electric supermini ranks because, despite appearances, it’s quite a rational proposition. It’s spacious, efficient and well-equipped, with an apparent sense of cabin quality. It’s competent and pleasant to drive, but for its slightly overbearing ADAS and fiddly infotainment. It’s great value, too, and a better car than you would expect at this price.

The kerb appeal to bear comparison with the Fiat Grande Panda Elettrica or Renault 5 may be missing, but those who prefer harder-headed qualities will find plenty of them of which to approve here – and we expect plenty will.
