What brand is the engine and transmission of the BYD Song MAX?

The engine of the BYD Song MAX is independently developed by BYD and is a domestically produced engine. The engine model of the BYD Song MAX is BYD476ZQA, with a maximum power of 118KW, maximum horsepower of 160, and maximum torque of 245Nm. For daily maintenance of the BYD Song MAX engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in 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 manufacturer's requirements; Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance will deteriorate, causing various problems for the engine. To avoid malfunctions, the oil should be changed regularly based on usage conditions, and the oil level should be kept moderate; When the oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, 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. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter 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 normal operation of the engine but also extends the overall lifespan of the radiator and engine.
I've researched the engine and transmission of the BYD Song MAX, which are both self-developed brands by BYD. In terms of the engine, the commonly used one is a 1.5T turbocharged engine, with models like the BYD476ZQB, delivering around 150 horsepower. It's relatively smooth and fuel-efficient, providing adequate acceleration for daily commuting. The transmission is a 6-speed wet dual-clutch (6DCT), also designed by BYD itself, with intelligent shift logic. There might be occasional slight jerks during city driving, but it's not a significant issue. Overall reliability is good, and BYD has strong technical expertise in the new energy sector. This vehicle also supports a hybrid version, with low maintenance costs, and it's generally convenient to service at authorized 4S shops. Remember to regularly check the transmission fluid to avoid minor faults caused by prolonged high temperatures. Maintain it well, and it can last for several years.
From an automotive enthusiast's perspective, the power units of the BYD Song MAX are all in-house branded. The engine is a 1.5T BYD turbocharged unit, commonly identified as the BYD476ZQB model, with reasonable performance parameters—delivering a maximum power output of around 110kW, which is well-suited for family needs. It's paired with a 6-speed wet dual-clutch transmission developed by BYD, known for its quick response and smooth gear shifts at highway speeds, though initial designs might exhibit slight feedback at low RPMs. As a leading domestic brand, BYD excels in electrification integration, offering a DM-i hybrid variant for this model that boasts excellent fuel efficiency and overall reliable quality. During maintenance, pay attention to air filter replacements to prevent minor issues from accumulating.
