Chinese auto giants have clashed in their quest to call their internal combustion engine the best in the world. An unusual criterion was chosen: thermal efficiency in the hybrid composition. BYD claims its fifth-generation DM-i powertrain uses a 46.06% efficient petrol unit, while Geely insists its NordThor PHEV system boasts a 46.1% efficient engine.

Both automakers provide certificates from the China Automotive Technology and Research Center, but it turned out funny. Geely provided data that the BHE15-CFZ engine actually produces an efficiency of 46.1%, but there is a nuance: the power plant with this engine did not go into production. In response, BYD showed a similar document with an efficiency of 46.5%, stating that it has many non-production engines with even greater efficiency.

The Americans dismantled the cheapest BYD and admitted that the United States was lagging behind. The sedan and crossover of the new Geely Galaxy sub-brand were presented. Mold and quality problems: BYD electric cars under fire

Further differences between Geely and BYD concern the range of hybrids. On this issue, achieving consensus is even more difficult, because everything depends on the measurement methodology. The WLTC standard produces representative, but not as impressive data, while the NEDC data makes it easier to set records. A striking example is the autonomy of up to 2,100 kilometers in the BYD Qin L sedan. This result is achievable with a fuel consumption of 2.9 liters per 100 kilometers, but according to the WLTC cycle the car is much more voracious – consumption is 3.8 liters per 100 kilometers.

Competition in the domestic market means that the “arms race” among Chinese electric vehicles and hybrids shows no sign of ending. Automakers from other countries are lagging behind: now in Japan and the USA they are dismantling BYD’s new products to get acquainted with the technologies and try to figure out the secret of low cost.
