BYD executives explain 2.9L fuel consumption: NEDC standards are more in line with China's actual driving environment

As of May 31, BYD’s recently launched Qin L and Dolphin i models claim that their 100-kilometer NEDC comprehensive cruising range reaches 2,100km. However, this claim has aroused doubts from some netizens, because they believe that BYD did not use the more stringent WLTC test standards to derive these data. Based on the WLTC test standard, the actual cruising range may be higher than the NEDC test standard to derive these data.

Faced with doubts, Yang Dongsheng, senior vice president of BYD Group and chief designer of DM technology, stood up and responded. He said that NEDC (European Endurance Test Standard) is more scientific in evaluating fuel consumption and is closer to actual driving conditions. He explained that the average vehicle speed under NEDC working conditions is 33km/h, which is consistent with the actual driving speed in major domestic cities. In Yang Dongsheng's view, in addition to fuel consumption, driving experience and vehicle configuration are equally important when judging the performance of a car.

According to our understanding, although some netizens and some industry observers have questioned BYD's fuel consumption data, a blogger named "Laigong Auto Review" even "reported with his real name" on Weibo that BYD is suspected of being false. Exaggerated propaganda, but these doubts have not shaken BYD's position. BYD insists that its data is based on the NEDC test standard and emphasizes that this standard is closer to the actual driving conditions of ordinary people. BYD said that the fuel consumption data is obtained through rigorous actual driving tests and has undergone extensive testing and verification in the Chinese market. BYD also stated that they have always been committed to providing reliable and authentic data to meet consumer needs and expectations. However, when it comes to vehicle fuel economy, consumers should make judgments and choices based on their actual usage and needs. In addition, consumption

In addition, BYD and Geely have also launched a secret war in terms of engine thermal efficiency. BYD claims that its fifth-generation DM hybrid system has achieved the world's highest engine thermal efficiency of 46.06%, while Geely has posted a certification from the China Automotive Center, showing that the thermal efficiency of one of its engines has reached 46.1%. However, this engine is not yet in series production. In response, Li Yunfei, general manager of the Brand and Public Relations Department of BYD Group, responded that BYD has an engine with higher thermal efficiency, but it has not been announced, and emphasized the importance.

This debate about fuel consumption and engine thermal efficiency has undoubtedly added fuel to the already bustling automotive industry. However, what is more important for consumers is to be able to see that car manufacturers are pursuing technological advancement while ensuring product authenticity and reliability.
