BYD and Geely's Engine Thermal Efficiency Battle

TapTechNews on May 29th reported that BYD released the fifth-generation DM hybrid last night, and the official claimed to have achieved three 'world records', one of which is the highest engine thermal efficiency of 46.06% globally.

However, this morning, Xu Dongwei, General Manager of the Brand User Communication Center of Geely Automobile Group and Deputy General Manager of Geely Automobile Sales Company, released a China Automobile Technology and Research Center certification certificate and said, 'In 2023, Geely's Thor engine has obtained the authoritative certification of the China Automobile Technology and Research Center, with the highest thermal efficiency of 46.1%! The global highest is determined by facts!' After that, the official Geely Automobile account forwarded this Weibo, and at the same time said 'The global highest is determined by facts'.

However, this engine of Geely has not been mass-produced yet, and it is planned to be mass-produced in 2025. The new-generation Thor electric hybrid engine BHE15Plus of Geely that was mass-produced and offline last February has a thermal efficiency of 44.26%.

TapTechNews noticed that Li Yunfei, General Manager of BYD Group's Brand and Public Relations Department, just seemed to respond to this matter and said, 'Mass production, mass production, mass production! Three times for important things. No false play, release means mass production! Listing means delivery!'
