Chinese giant's latest EV is meant to allow buyers on a budget to go electric without making any compromises

The new BYD Dolphin Surf is billed as the car that'll bring mass electrification to the small car market.

While a large percentage of big cars are electrified (or part electrified), with small, affordable cars, the proportion is much lower. The BYD Dolphin Surf is one of a raft of recent vehicles (alongside vehicles like the the Dacia Spring, Hyundai Inster and Renault 5) that sets out to change that.

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...

While BYD is a lesser known brand than its rivals, it has more credentials in this area than any one else: it already makes more electric cars than anyone else in the world, while Dolphin Surf prices start at £18,650.

You might recognise the Dolphin Surf as the BYD Seagull – an electric car that recorded almost half a million sales in its first year on sale.

The resemblance of its ‘face’ to that of a seagull dive-bombing to steal your chips is no coincidence – and us making that negative association is why the name has been changed over here. As for the new one? The first half draws an obvious link to the larger electric hatchback that BYD sells; the second half is intended to give the car a fun, zesty, youthful image.

DESIGN & STYLING

BYD Dolphin Surf review 2025 02 tracking

The few previous attempts at an affordable A-segment EV have produced acceptable enough but rather cheap-feeling results in the Dacia Spring and Leapmotor T03.

The Surf is intended to feel entirely like a ‘proper’ car while being no more expensive than those rivals. As such, it’s based on the same e-Platform 3.0 that underpins the impressive BYD Seal electric saloon, which incorporates BYD’s cutting-edge Blade Battery technology (it’s said to be safer and more durable than rival batteries and features no rare cobalt), and uses BYD’s ‘eight-in-one’ electric powertrain, which improves efficiency and saves space by combining the motor, reducer, charger, DC converter, power distribution box, battery management controller, vehicle control unit and motor controller.

At 3990mm long, 1720mm wide and 1590mm tall, the Surf is the same length as the Renault 5 but narrower and taller.

There are two variations of the lithium-iron-phosphate (LFP) battery on offer in the Surf, with usable capacities of 30kWh and 43.2kWh and maximum rapid-charging rates of 65kW and 85kW. That's from the fastest on the market, but then they’re also far from the biggest.

The smaller battery is paired with an 87bhp motor in the Active £18,650 model for a 137-mile range and an 11.1sec 0-62mph time.

The larger battery is teamed with the same motor for a 200-mile range and a 12.1sec time in the £21,950 Boost model; or with a 154bhp motor for a 193-mile range and a 9.1sec model in the rather confusingly named Comfort model, which we’re driving here. It costs £23,950.

This puts the Surf far ahead of the Spring (140 miles) and T03 (165 miles) and roughly on par with the Citroën ë-C3 – despite its pricing being in line with the Spring and T03, rather than the ë-C3.

Standard equipment is generous as well: the T03 feels quite basic inside in comparison to the Surf and its large, Apple CarPlay-equipped touchscreen, array of attractive, soft-feeling materials and faux-leather sports seats. 

You can then add 15in alloy wheels, rear parking sensors, a parking camera, keyless entry and adaptive cruise control to the count.

Step up to the Boost for larger (16in) alloys, electric seat adjustment and automatic wipers; and to the Comfort for a 360deg camera, LED headlights, tinted rear windows, heated front seats and a wireless phone charging pad.

INTERIOR

The practicality of this interior also impresses. Two above average-sized adults can fit in the rear (albeit strictly two; as in the T03, there is no middle seat), the boot capacity matches that of the ë-C3 almost exactly (308 litres versus 310 litres) and there’s plenty of oddment storage.

Perceived material quality, which is common across all trim levels, feels much higher than, say, a Dacia. Spring's. But at the Surf's higher end the Renault 5 gives it stiffer competition. 

The boss of the steering wheel is a large disc of shiny black plastic, which daylight turns into a kind of smoky make-up mirror.

The touchscreen infotainment system has BYD's trademark capacity to rotate between landscape and portrait orientation, although we suspect you'll pick one and go with it. It's relatively easy to navigate but perhaps a little too demanding of someone who is meant to be driving; not that there's too much surprising in that these days.

Commendably, especially for a Chinese car, there is a row of physical buttons on the dashboard to complement those on the steering wheel (which control the adaptive cruise control and media). These silver plastic dials control the gears (tap the left side to engage park, air conditioning and ventilation). You can drag three fingers across the screen to change the temperature or fan speed.

 

ENGINES & PERFORMANCE

You might fairly wonder whether this is a case of BYD chucking in all the goodies in an attempt to compensate for a fundamentally underwhelming product. After all, the driving experiences offered by the company’s UK-market cars have been curiously hit-and-miss: whereas the Seal is supple and engaging, the Seal U suffers from vague steering and overly soft suspension.

Well, the Surf falls somewhere in the middle of those two descriptions.

Floor the accelerator with a little bit of lock on and you can get punished with some scrabbly torque steer.

In urban environments, where it will spend most of its time, it’s very good. 

The powertrain is smooth. We've yet to try the lower models' power output, but the 154bhp offered by the Comfort makes it very sprightly on the road, especially given that a motor does its best work from low speeds. At higher speeds the Comfort model retains strong response and acceleration even at higher speeds

The regenerative braking has two strengths, but isn't that strong even in its more powerful setting (as with the steering, changed via a sub-menu on the touchscreen), meaning that one-pedal driving is a near impossibility. Whether that’s a good or bad thing will be a matter of taste.

Brake feel is a weak point, with a mushy, not linearly-responsive pedal feel. You'd get used to it, but rivals do it better.

RIDE & HANDLING

The Surf is marketed as an urban-friendly car and its eide comfort is absorbent at low speeds. The turning circle is good and the steering has a nice medium weighting to it in Normal mode (there’s also a Sport mode, but the difference is hardly noticeable) and the springy self-centring is useful enough around town.

Get onto faster roads, however, and the dynamic appeal of the Surf diminishes notably. The body heaves over crests and bumps, and the steering takes on a certain stickiness. That the brake feel is also non-linear makes it an underwhelming car to drive on tougher roads. 

Try and hustle the Surf down a good road and you will pretty quickly think better of the endeavour.

Still, for a car that is centered on being at its best in urban areas, it doesn’t feel out of depth on a motorway, where it will cruise along in comfort and admirable quietness and, with the Comfort model's level of power at least, enough oomph in reserve for overtakes. Whether that's also the case in the lower output models we'll have to see.

MPG & RUNNING COSTS

At the time of writing we've driven the Surf in Italy and in the UK on mixed, but relatively brief routes, but according to the trip computer returned well over 4mpkWh both times, enough to almost match the car's WLTP combined range. It's worth noting that conditions were warm both times and there was a decent amount of urban driving, which is kinder to EV's ranges than, say, motorways. We'll be able to tell you more when we fully road test the car in the UK.

BYD says that trusted components are one of its selling points. It's too early to see many BYDs, or any Surfs of course, in running cost or customer satisfaction surveys, and residual values are just estimates at the moment too, so there's also more to come later on those fronts.

My day of driving around Rome and the surrounding countryside used only 35% of the battery. Just shows how well an EV can work for many people.

 

VERDICT

BYD boss Stella Li described the Surf to us as “the car for everyone” and there's no question that because of its range, pricing and perceived interior quality, it offers a blend of attractive qualities in the rarefied small car market.

Being one of relatively few cars available at this price, with full electrification, makes its features stand out even more. When, or if, more cars arrive at this size and price, its appeal may diminish.

Meanwhile, it may be no dynamic wonder, and it may lack the retro chic of the Renault 5, but it is an attractive, generously equipped, practical EV that offers an agreeable range at a keen price – an amount of money that will otherwise only get you something that feels significantly less mature.
