Chery has developed a record engine: 48% efficiency and lower fuel consumption.

According to Korrespondent.net: At the 2025 International Users' Summit, Omoda & Jaecoo, part of Chery Group, presented a new internal combustion engine with an impressive efficiency coefficient of 48%. As reported by Motor1, this is one of the highest figures in the global automotive industry, where the average level usually fluctuates between 38-45%.

Despite the active development of electrification, the manufacturer is confident that hybrid technologies will remain the most effective way to reduce energy consumption in the coming years. Each additional percentage of thermal efficiency, as explained by the company, means about 2.5% savings on fuel, as well as a significant reduction in CO2 emissions.

Technical Innovations

Chery Group's engineers achieved these figures through a series of technical solutions: an ultra-high compression ratio of 26:1, a triple hyperbolic mechanism, 35% recirculation of exhaust gases, and special thermal insulation coatings that reduce heat loss during combustion.

Results of the SHS System

The summit also showcased the results of the cutting-edge SHS (Super Hybrid System), which combines a 1.5 TDGI engine with Miller cycle, two electric motors, and a smart DHT transmission. This combination ensures a thermal efficiency of 44.5% and a fuel consumption of only 6 liters per 100 km.

The hybrid system automatically adjusts driving modes depending on speed and load, while the battery withstands high temperatures, impacts, and immersion in water. In case of a collision, it disconnects instantly - in 2 milliseconds. Additionally, the SHS allows for up to 90 km of electric-only driving and supports V2L functionality, enabling the powering of external devices up to 3.3 kW.

It should be noted that earlier, it was reported that Chery presented a battery for electric vehicles that provides a range of 1300 km.
