What engine does the BYD M6 use?

[Jeanette]

The engine of the BYD M6 is a domestically produced engine, manufactured by Shenyang Aerospace Mitsubishi Automobile Engine Manufacturing Co., Ltd. The 2.0L version of the BYD M6 uses the BYD483QB engine model, with a maximum power of 103 kW and a maximum torque of 186 Nm; The 2.4L version uses the 4G69 engine model, with a maximum power of 118 kW and a maximum torque of 215 Nm. For daily maintenance of the BYD M6 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, with the selection standard not lower than the requirements specified by the manufacturer; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine problems. To avoid malfunctions, the oil should be changed regularly according to usage conditions, with an appropriate oil level maintained; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve 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, mixing with metal powder from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

During my years driving the BYD M6, I found it mostly equipped with a 2.4L naturally aspirated gasoline engine, especially in earlier models around 2015. That was a Mitsubishi-technology-based engine called the 4G69 model, delivering quite smooth power output with moderate acceleration—perfect for family trips like mine. In city driving, it averages around 10L per 100km, not the most fuel-efficient but acceptable. On highways, the engine noise is relatively low, and reliability is decent, handling occasional uphill drives without much effort. If fuel costs are a concern, you could opt for the later turbocharged 1.5T version, which offers more horsepower but slightly higher maintenance costs. Overall, the M6’s engine design emphasizes practicality, and its spaciousness makes it a cost-effective family car. However, BYD now focuses on new energy vehicles, so this older engine falls short in emissions compared to newer hybrid models.

I've driven the BYD M6 as a commuter car several times, and its engine is quite powerful. It mainly uses a 2.4-liter gasoline engine, with the base models equipped with BYD's self-developed system, like the BYD487ZQA code, outputting over 150 horsepower. The acceleration is responsive, especially when stepping on the gas pedal on the highway, with an average fuel consumption of around 11 liters per 100 kilometers. As a young person, I like that it has sufficient power without being expensive, and maintenance costs just a few hundred yuan each time. However, I'm more envious of the newly released 1.5T version—the turbocharger makes starting off more vigorous, and overtaking during daily commutes is effortless. Although pure gasoline can't match the energy efficiency of BYD's DM-i hybrid, it's more affordable, and the M6's engines have fewer faults in the second-hand market. I suggest checking the owner's manual to confirm the model first, rather than just relying on advertisements.

In my daily experience of car repairs, the BYD M6 is mostly equipped with a 2.4L gasoline engine, such as the BYD487ZQA model. This is a veteran engine with good durability. Common issues are mostly caused by carbon buildup or aging spark plugs leading to increased fuel consumption. With proper maintenance, it can easily last 100,000 kilometers without major issues. Changing the oil and air filter is simple, but the belt tensioner needs regular attention, especially since the M6 is an older model. Some second-hand owners complain about unstable idling, which can be resolved by cleaning the throttle body. Compared to the turbocharged 1.5T version, the basic engine is cheaper to repair, and parts are easier to find. Overall reliability is decent, with regular maintenance being the key.
