The BYD Dolphin 2025 Intelligent Driving 420KM Freedom Edition is a compact all-electric hatchback positioned as the entry model of the Ocean Series, sitting between the Seagull and the Seal 06. It is designed for young buyers and family users, combining affordability with smart features to provide a practical choice in the small EV segment.
Within the lineup, the Dolphin stands out against rivals such as the Wuling Bingo PLUS and Leapmotor T03, offering stronger range and faster charging capability. This makes it especially competitive among entry-level urban EVs.
Powered by a 70 kW front motor, the Dolphin accelerates from 0–50 km/h in just 4.3 seconds, making it responsive for stop-and-go city driving. On a full charge, it delivers around 420 km of range, sufficient for daily commuting and urban errands.
Fast-charging support further enhances convenience. Recharging from 30% to 80% takes about 25 minutes, which eases charging concerns during weekend getaways or short intercity trips.
The exterior follows a youthful, dynamic design. A short-overhang hatchback body is paired with dual-tone roof options, such as black with white or black with blue. Together with through-type tail lights and sporty alloy wheels, the Dolphin presents a stylish, modern look that resonates with younger drivers.
Interior space is well considered. A 2,700 mm wheelbase, rare for this class, ensures rear-seat comfort. The trunk offers 345 L of cargo space, expanding to 1,320 L with the rear seats folded, making it versatile for daily needs as well as family outings.
Balancing long range, low running costs, and intelligent driving assistance, the Dolphin 420KM Freedom Edition is both an agile city commuter and a flexible companion for family travel or ride-sharing. It makes EV ownership more practical and accessible for everyday life.
