BYD, the world's largest EV manufacturer, sold over 4.27 million electric and plug-in hybrid vehicles in 2024 alone — a 41% increase over 2023. The Dolphin, the most affordable model in BYD's “Ocean Series,” is at the heart of this global push: an electric hatchback under $30,000 with over 250 miles of range.
Trims & Specs
The 2025 BYD Dolphin comes in four trims, all built on BYD's LFP Blade Battery — a cobalt-free lithium-iron-phosphate pack known for exceptional durability and safety.
| Trim | Battery | Range (WLTP) | Power | Price (UK) |
|---|---|---|---|---|
| Active | 44.9 kWh | 211 mi | 94 hp | £26,195 |
| Boost | 44.9 kWh | 195 mi | 174 hp | £27,195 |
| Comfort | 60.4 kWh | 265 mi | 201 hp | £30,195 |
| Design | 60.4 kWh | 265 mi | 201 hp | £31,695 |
* In China, the 2025 Dolphin starts at just $13,700 (RMB 99,800). The 700,000th unit rolled off the line in July 2024.
Blade Battery: The Secret Weapon
BYD's Blade Battery technology is one of the Dolphin's most impressive features. Instead of traditional cylindrical cells, it uses flat “blade” cells arranged lengthwise across the platform. The result:
- Cobalt-free (LFP) — Safer chemistry, temperature resistant, with an enormous cycle life
- 8-year / 125,000-mile warranty — Guaranteed to retain at least 70% capacity
- Nail penetration test — The Blade Battery passed puncture testing without catching fire — something very few batteries achieve
- Lower center of gravity — The flat layout improves stability and handling

"The Blade Battery, being an LFP chemistry, means that the body will rot out from around the battery long before the battery goes bad. People will literally be able to drive these things for decades with virtually no thought to maintenance." — CMG30, electrek.co
Interior & Space
At 4,290 mm long, 1,770 mm wide, and 1,570 mm tall, the Dolphin sits between a supermini and a hatchback — roughly similar to the VW ID.3. Despite the compact footprint, interior space is impressive:
- 345-liter trunk — Impressive for the class, with adjustable floor
- Rear space for adults — Comfortably fits passengers over 6 feet tall
- Rotating 12.8″ screen — Switches between landscape and portrait, though the interface takes getting used to
- USB-C ports — Well-placed below the screen
- 360° camera — Standard across all trims
According to Autocar UK (7/10 rating), the interior feels noticeably better than the MG4 in material quality, though the touchscreen interface remains overly complex while driving. Icons are tiny, sub-menus plentiful — but the screen responds quickly to touch inputs.
Driving Experience
The Dolphin doesn't aspire to be sporty — it's designed for comfortable daily use. The suspension is soft, offering an almost “floating” feel on the highway. The Comfort trim (201 hp) does 0-62 mph in 7.0 seconds, plenty quick for everyday driving.
On the downside: steering feels light and numb, and rough roads can unsettle the ride. DC fast charging tops out at 65 kW (small battery) or 88 kW (large battery) — meaning a 10-80% charge takes about 38-40 minutes. Respectable, but slower than competitors like the Peugeot e-208 (100 kW).
Standard Equipment
One of the Dolphin's strong suits is that all trims share a generous standard equipment list:
- Heat pump — improves winter range
- V2L (Vehicle-to-Load) — power external devices from the car
- 360° camera — excellent image quality per testers
- Adaptive cruise control
- Full ADAS suite (Lane Keep, Emergency Braking, etc.)
- Rotating 12.8″ infotainment screen
Dolphin vs the Competition
The main competitor is the MG4, which starts at a similar price but offers slightly more range in its Long Range trim (281 vs 265 miles). However, the Dolphin excels in:
- Interior quality — Softer materials, more premium feel
- Warranty — 6 years/93,750 mi + 8 years/125,000 mi battery
- Battery safety — The Blade LFP is considered one of the safest on the market
- Color palette — Pink, purple, orange — rare choices in the EV market
Compared to European rivals like the Peugeot e-208 or Vauxhall Corsa Electric, the difference is striking: the Dolphin offers significantly more space and more range at a lower price.

BYD & the European Market
BYD has become the fastest-growing EV manufacturer in Europe. In 2025, the Dolphin Mini (Seagull) won the World Urban Car Award — making BYD the first Chinese brand ever to win a World Car Awards title. EU tariffs (17.4% additional for BYD) have slightly impacted pricing, but BYD has absorbed much of the cost increase to remain competitive. In Europe, the Dolphin comes with an official service network and a 6-year/150,000 km vehicle warranty plus 8 years for the Blade Battery. Compared to European rivals, such as the Renault 5 E-Tech (52 kWh, 255 miles) and Citroën ë-C3 (44 kWh, 199 miles), the Dolphin clearly leads in range and battery capacity, while also offering a superior heat pump system for efficient winter heating. The only notable weakness remains DC fast charging: 88 kW max power, well behind the 150+ kW offered by newer competitors.
Verdict
The BYD Dolphin isn't perfect — fast-charging needs improvement and the infotainment could use work. But under $30,000, it offers what no European EV can match: 265 miles of range, generous interior space, a Blade Battery with 8-year warranty, and rich standard equipment. The Dolphin also supports V2L (vehicle-to-load) for powering appliances up to 3.3 kW — handy for camping trips or emergency power. If you're looking for an everyday EV without compromising on range, the Dolphin is one of the best values on the market in 2026.
