EUROPE, October 29, 2026 — The fully electric BYD Dolphin Surf has received a five-star Green NCAP Sustainability Rating, with an overall score of 96% in assessment results published on October 29, 2026.
Green NCAP assessed the front-wheel-drive BYD Dolphin Surf Boost, equipped with a nominal 43 kWh battery. The rating evaluates environmental performance, including energy consumption and greenhouse-gas impact, and is separate from the vehicle’s five-star Euro NCAP crash-safety rating awarded in 2025.
Green NCAP scores for the BYD Dolphin Surf
The assessment gave the Dolphin Surf a score of 9.7 out of 10 for Clean Air, 9.5 out of 10 for Energy Efficiency and 9.9 out of 10 for Greenhouse Gases. Its combined Sustainability Rating was 96%, corresponding to five Green NCAP stars.
The organisation said the car’s compact size, relatively low vehicle weight, small battery and energy recuperation contributed to its performance. As a fully electric vehicle, it produces no tailpipe exhaust emissions, although lifecycle emissions remain part of the environmental assessment.
Measured electricity consumption and lifecycle emissions
Energy consumption varied between 11.2 and 17.2 kWh per 100 km in the road and urban measurements described in the assessment. In the more demanding highway laboratory test, electricity use reached 27.9 kWh per 100 km.
Green NCAP calculated lifecycle greenhouse-gas emissions of 112.5 grams of CO2-equivalent per kilometre for the assessed vehicle, including approximately 61 grams per kilometre attributable to its production in China. The organisation noted that generic production data, rather than model-specific manufacturer-verified production data, were used for this assessment.
Charging performance and vehicle-to-load function
The assessment reported a DC fast-charging time of approximately 33 minutes for a 10–80% battery-charge increase. Home-charging efficiency, measured from the electricity grid to battery output, was 86.8%.
The Dolphin Surf Boost also offers vehicle-to-load functionality, allowing it to supply external electrical equipment with up to 3.3 kW at 230 volts. Green NCAP included this capability in its evaluation of the car’s everyday charging and energy functions.
Cold-weather observations and vehicle range
Green NCAP found that the 43 kWh battery and compact vehicle size limit the car’s potential driving range, particularly on longer journeys. It also recommended preheating the car while connected to a charger before driving in cold conditions to help preserve available range.
During cabin-heating tests, the organisation reported that the rear footwell did not reach the 16°C target temperature. It described the cabin’s thermal insulation as adequate and noted that the tested version had manual climate control.
The five-star result refers specifically to Green NCAP’s environmental Sustainability Rating for the tested Dolphin Surf Boost configuration. It should not be confused with the independent Euro NCAP safety assessment.
