Geely unveils the EM-i plug-in hybrid technology, with test results showing improved efficiency and longer range compared to BYD’s system.
Geely has officially introduced the EM-i plug-in hybrid system (NordThor 2.0), boasting superior specifications to BYD’s DM 5.0 engine. This system comprises an internal combustion engine (ICE) with the highest thermal efficiency globally and an 11-in-1 electric drive system.
The new setup pairs a 1.5-liter naturally aspirated gasoline engine with a thermal efficiency of 46.5%, which Geely claims is the best in the world. This engine is also capable of running on methanol and operating at temperatures as low as -35 degrees Celsius, coupled with a 214-horsepower electric motor.
Test results indicate that Geely’s EM-i technology consumes only 2.62 liters of gasoline per 100 kilometers, offering a combined gas-electric range of up to 2,390 kilometers. This surpasses BYD’s newly launched PHEV system from May 2024, which consumes 2.9 liters per 100 kilometers and has a range of 2,100 kilometers when fully charged and fueled.
In real-world testing, a Galaxy Starship 7 equipped with the EM-i powertrain achieved a fuel consumption rate of 3 liters per 100 kilometers.
Geely states that this new hybrid technology will also be implemented in Renault, Volvo, and Lotus vehicles. While Volvo and Lotus are subsidiaries of the group, Renault is currently a strategic partner of Geely.
Currently, BYD leads the plug-in hybrid and electric vehicle sales rankings in China, with a market share of 34.6% for the first three quarters of 2024. This is significantly higher than Geely’s 7.4% and Tesla’s 6.5%.
BYD broke quarterly sales records in Q3 of 2024, with a 76% increase in plug-in hybrid sales, amounting to 685,830 units.
