Where is the MG car engine from?

MG car engines are jointly developed by SAIC Motor and General Motors and are produced in SAIC's engine factories. Most MG cars use the "Blue Core" SGE20T engine. For example, the MG MG6 is equipped with a 1.5-liter turbocharged engine, delivering a maximum power of 124 kW, a maximum torque of 250 Nm, a maximum power speed of 5500 rpm, and a maximum torque speed of 170 Nm. For the daily maintenance of MG car engines, the following methods can be applied: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD-SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB-CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will degrade over time. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures the engine operates smoothly but also extends the overall lifespan of the radiator and engine.
I've been researching MG Motors for quite some time, and this issue needs to be viewed from its development history. Early British MG models used Rover engines, and after being acquired by Nanjing Automobile, they continued using this technology. When SAIC took over in 2007, the localization process began. Currently, the best-selling MG5 and MG6 models are powered by SAIC's self-developed Blue Core engines, with the 1.5T version showing particularly impressive specifications. In fact, SAIC has technical cooperation with General Motors - the 1.3T engine in the MG ZS uses GM technology, though the entire production line is domestic. The recently launched electric model MG4 uses motors from SAIC's Nebula pure electric platform, demonstrating increasingly strong independent R&D capabilities. It's fair to say MG engines have long been Sinicized, retaining only British design elements.
As a frequent MG owner, I've found that engine origins depend on the specific model. The older MG7 indeed carries the technological legacy of British Rover, but current models all use engines produced at domestic manufacturing bases. My 2021 MG6 clearly states on its nameplate that it's manufactured by SAIC Motor Passenger Vehicle Company, with its 1.5T Blue Core engine achieving 40% thermal efficiency. During maintenance, technicians mentioned that MG's current engine control systems are jointly developed by SAIC and United Automotive Electronic Systems. The new MG ONE even features advanced technologies like a 1.5T high-pressure direct injection engine with variable displacement oil pump. While the brand originated in Britain, its core components have long been Made in China.
