BYD's Fuel Consumption Data Questioned, and Responses from BYD and Geely
TapTechNews May 30th news, according to reports from EachDay Intenet, just two days after the listing of BYD Qin L and Seal 06 DM-i, which claimed a NEDC fuel consumption of 2.9 liters per 100 kilometers and a comprehensive driving range of 2100 kilometers, some netizens questioned whether BYD's fuel consumption data did not use the WLTC test standard.
Yang Dongsheng, senior vice president of BYD Group and the chief designer of DM technology, responded that NEDC (i.e. the European driving cycle test standard) is relatively more scientific to evaluate fuel consumption, and it is a working condition closer to the common people.
Specifically, the average speed in the NEDC condition is 33 kilometers per hour. When the Ministry of Industry and Information Technology required the condition to be upgraded to WLTC, the average speed was 47 kilometers per hour. Yang Dongsheng said that in major first-tier cities, the average speed is 25 kilometers per hour or even 23 kilometers per hour, and in second-tier cities it is also more than 30 kilometers per hour. In China, the normal driving speed under working conditions is below 30 kilometers. When evaluating the performance of a car, although fuel consumption is important, driving experience and vehicle configuration should not be ignored.
NEDC is the European driving cycle test standard, in which the urban condition consists of four ECE cycle units. In the test process, the maximum speed is 50 kilometers per hour, the average speed is 19 kilometers per hour, and each cycle time is 195 seconds, with a total travel distance of 4.052 kilometers.
In an interview, Geely Automobile said, Regarding the matter of netizens reporting BYD (2.9 liters of fuel consumption), we will not make any comments. But for Geely, it is definitely necessary to insist on doing the right thing and the real thing.
It is known that a blogger named Lai Gong Car Review declared on Weibo yesterday that he submitted a real-name report against BYD Qin L and Seal 06, believing that BYD was suspected of false and exaggerated publicity. (As of today, the original Weibo has been deleted.)
According to a previous report by TapTechNews, BYD's fifth-generation DM hybrid claimed to achieve three global bests, one of which is the world's highest engine thermal efficiency of 46.06%. However, Geely showed a certificate of authentication from the China Automobile Center: In 2023, Geely's Leishen engine has obtained authoritative certification from the China Automobile Center, with the highest thermal efficiency of 46.1%! The global highest is based on facts! However, this engine of Geely has not been mass-produced yet and is planned to go into mass production in 2025. Geely's new-generation Leishen electric-hybrid engine BHE15Plus, which went into mass production and off the line last February, has a thermal efficiency of 44.26%.
