What engine is used in the BYD Surui?
3 Answers
The engine of the BYD Surui is independently developed and produced by BYD Auto Company, belonging to a domestically manufactured engine. The engine model of the BYD Surui is BYD476ZQA, with a maximum power of 80kW, maximum horsepower of 109, and maximum torque of 145 N·m. For daily maintenance of the BYD Surui engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices 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 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, the performance deteriorates, causing various problems for the engine. To avoid 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 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. A small amount remains suspended in the oil, while a large amount 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.
As a car enthusiast who has driven the BYD Surui several times, I must say its engine is quite reliable. It primarily uses a 1.5L naturally aspirated gasoline engine, typically the BYD473QE four-cylinder model, delivering around 80kW of power output. The driving experience is smooth, with decent acceleration from standstill. For daily city driving, fuel consumption is reasonable at approximately 6.5L per 100km, making it suitable for family trips or commuting. On long-distance drives, noise control is impressive at stable RPMs. Popping the hood reveals a compact engine layout that's relatively easy to maintain. If you're on a budget, this car offers exceptional value - the base engine proves durable, showing no major issues even after years of use. Just remember to maintain it regularly, using standard 92-octane fuel, and avoid unauthorized modifications that could affect its lifespan.
I usually drive my BYD Surui to take the kids to school, powered by the familiar 1.5L gasoline engine. It feels adequate for daily use—not particularly fast in acceleration but stable, and overtaking isn't too difficult. I've always been satisfied with its fuel consumption: around 7L per 100km in city driving, dropping to about 6L on the highway. A full tank can easily cover 500km. The engine's reliability has been decent; over three years of driving, I haven't encountered overheating or stalling issues. Routine maintenance like oil changes and air filter replacements is quite affordable and can be handled at local repair shops. Some owners complain about the engine being a bit noisy, but in my experience, it's not a major issue—installing good sound insulation helps. Overall, this engine is economical and practical, well-suited for cost-conscious families like mine.
