Geely overtakes BYD with the EM-i plug-in hybrid system
Geely officially revealed the EM-i (NordThor 2.0) plug-in hybrid system with better specs than the BYD’s DM 5.0 powertrain. It comprises an ICE with the world’s highest thermal efficiency rate and an 11-in-1 electric drive. The NordThor 2.0 offers a mixed range of 2,390 km and a fuel consumption of 2.67 L/100km.

Plug-in hybrid vehicles are gaining momentum in China, with BYD as the leading company. However, other Chinese car makers are slowly catching up with the Shenzhen-headquartered company. For example, the SAIC-owned Roewe has recently set a Guinness World Record for the longest distance covered by a PHEV with their sedan D7 DMH (see specs). The Chery Fulwin T10 made the world’s record as the plug-in hybrid SUV with the longest mixed range.
On October 30, Geely revealed the latest variant of its NordThor PHEV platform that will allow it to rival the BYD’s DM 5.0 powertrain. The first car with this system on board is the Geely Starship 7. It will enter the market on November 4 this year.

More about Geely’s NordThor 2.0 system
The Geely’s NordThor powertrain has two different modifications. The first one is a performance-focused EM-P system. It is currently adopted by Lynk & Co branded cars. Another variant of the NordThor system is DM-i. This version is also referred to as the NordThor 2.0 powertrain.
The Geely’s EM-i plug-in hybrid comprises a 1.5-liter naturally aspirated engine with the world’s highest thermal efficiency of 46.5%. Previously, the BYD’s 1.5-liter ICE had the highest thermal efficiency rate. The Geely’s engine can also use methanol and work at -35°C.
Back to Geely’s EM-i system, it integrates an 11-in-1 electric drive (E-DHT). It comprises P1 and P3 electric motors, a control system, a SiC module, a VCU (vehicle control unit), a TCU (transmission control unit), a PDU (power distribution unit), a transmission, and an active G-TCS system.

The NordThor 2.0 system’s P3 electric motor has a peak power output of 160 W (214 hp). The motor boasts an efficiency of 98.02%. The electric drive’s overall efficiency is 92.5%, 0.5% higher than that of the BYD DM 5.0.
The EM-i system also comprises the patented backup technology for ICE and P1 & P3 e-motors. If any of the components fail, the car will still be able to drive normally. Geely officials underlined that they have tested the Galaxy Starship 7 crossover for 2 hours at a high speed of 155 km/h. During the test, the car had no signs of performance degradation. The EM-i system also has a thermal management system with an energy consumption decreased by 30%.
Speaking about specs, the Geely EM-i system has a mixed range of 2390 km. The ICE fuel consumption is 2.67 liters per 100 km. The Geely Galaxy Starship 7 will become the first car to adopt the EM-i system. It will enter the Chinese market on November 4.
