BYD Dolphin, Atto 3 Impresses Green NCAP When It Comes To Range


BYD impresses when it comes to its “green” credentials. The Green New Car Assessment Program or Green NCAP recently awarded the two vehicles it sells in Europe, the Atto 3 and Dolphin, perfect 5-star ratings.

The Green NCAP is an independent initiative dedicated to promoting cars that are clean, energy-efficient, and environmentally friendly. It focuses on improving air quality, conserving resources in passenger transportation, and mitigating global warming.

Tests cover various scenarios such as energy efficiency in both cold and warm conditions, highway cycles, and real-world driving scenarios. The highest standard is attributed to a car that maximizes the reduction of its own pollutants and greenhouse gases and, at the same time, operates at minimized fossil fuel and/or electricity consumption under real-world conditions.

The Atto 3 EV SUV (read our review) scored 97 percent. Broken down, it scored 10 out of 10 in Clean Air Index, 9.5 out of 10 in Energy Efficiency Index, and 9.7 out of 10 in Greenhouse Gas Index.

Testers noted that test consumption values are close to their declared values. Of note, the Atto 3 had excellent cold weather range (3.98 km/kWh) thanks to a well-designed heating system, using different sources of waste heat to condition the battery.

At the battery capacity test the vehicle was charged with 11-kW charging power. With 59.3 kWh, the measured usable battery capacity matches closely the declared figure of 60 kWh. The full battery recharge takes 68.4 kWh from the electricity grid, which results in a rather moderate grid-to-battery output efficiency of 87 percent.

Meanwhile, the Dolphin EV hatchback (read our review) managed an even higher score: 98 out of 100. Broken down, it scored 10 out 10 in Clean Air Index, 9.6 out of 10 in Energy Efficiency Index, and 9.9 out of 10 in Greenhouse Gas Index.

According to the Green NCAP, the Dolphin obtains real-world figures close to its WLTC test (5.88 km/kWh). Because of this, it’s still capable of reaching up to 400 kilometers per charge despite its modest battery size. The Dolphin is also equipped with the same thermal management system found in the Atto 3.

Meanwhile, its grid-to-battery output efficiency is rated at 85 percent meaning it can top up to 100 percent by drawing 56 kWh from the electricity grid.
