The BYD Dolphin (Chinese: 比亚迪海豚; pinyin: Bǐyǎdí Hǎitún) is a battery electric hatchback produced by the Chinese manufacturer BYD Auto since 2021. A subcompact (B-segment) hatchback, the Dolphin is positioned above the Seagull in the Chinese market and part of BYD's Ocean Series.[11]

The Dolphin has been exported to overseas markets such as Europe, Australia and Southeast Asia since 2023 with lengthened dimensions to satisfy more stringent crash safety standards, and placing it in the compact or C-segment space.[12]

Overview

During Auto Shanghai in April 2021, BYD presented a pre-production prototype of the Dolphin called BYD EA1 Concept, while also announcing a modernized design language and company logo.[13] The company also introduced presented a new generation of electric car platform called the e-Platform 3.0, which offer more efficient performance and range.[13]

The production model was presented three months later as the BYD Dolphin, and became available in August 2021.[14] The Dolphin adopts BYD's Marine Aesthetics design language that is also used in other Ocean Series models, a one-box side silhouette devised by head of BYD design team Wolfgang Egger.[13] The Dolphin was the first production model to feature the new BYD logo.[15]

The interior of the Dolphin features a rotatable 12.8-inch infotainment screen, and a full 5-inch LCD instrument panel. It comes standard with the LFP blade battery in varying capacities.[16]

The modified version destined for the global market was introduced in 2023. For most export markets, the Dolphin was lengthened by approximately 20 cm (7.9 in) in order to accommodate a new front-end crash structure, which was designed to achieve a five-star Australian ANCAP safety rating. The global model received different front and rear bumpers, front hood and wing fenders that extended its overhang, which increased its length to 4,290 mm (168.9 in) and placing it as a C-segment car.[17]

On 22 September 2023, the 500,000th Dolphin rolled off the assembly line after 25 months in production.[18]

2025 facelift

The Dolphin received a major update in March 2025 for the Chinese market.[19] The model received a redesigned front and rear design which increased its length by 130 mm (5.1 in), revised dashboard design, and a steering-mounted gear selector. It is also equipped with BYD's latest advanced driver assistance system marketed as God's Eye C and DiPilot 100 as standard.[20]

Recall

When the tool cover is closed, it may press against internal components, causing tiny cracks. Over time, these cracks may expand and lead to short circuits, overheating, or fires. BYD dealers would install insulation pads on the controllers to eliminate the safety risk.[53][54]
