BYD Song Pro uses a self-developed engine by BYD, with the model code BYD476ZQB, a displacement of 1.5 liters, and belongs to the turbocharged engine category. This engine has a maximum horsepower of 160ps, a maximum power of 118kw, a maximum torque of 245nm, a maximum power speed of 5200rpm, a maximum torque speed ranging from 1600 to 4000rpm, a direct injection fuel supply method, and the cylinder block and cylinder head are made of aluminum alloy. BYD Song Pro is a compact SUV produced by BYD Auto. In terms of body dimensions, its length, width, and height are 4650mm, 1860mm, and 1700mm respectively.

I've been quite interested in BYD's vehicles, especially the Song Pro model, which I've been using for a while. Its current engines are all BYD's in-house products, like the latest DM-i hybrid version's Xiaoyun 1.5L plug-in hybrid dedicated engine, which boasts ultra-high thermal efficiency and is extremely fuel-efficient on the road. I once drove a friend's Song Pro fuel version, also equipped with BYD's 1.5T turbocharged engine, and the acceleration was quite powerful. However, now it's mostly transitioning to new energy, with self-developed engines and motors perfectly matched, making the ride quiet and smooth. When stuck in traffic, using electricity doesn't make me worry about fuel costs at all, and the technological maturity is truly impeccable.

I just bought a Song Pro DM-i and have been driving it for about half a year. The engine is independently developed by BYD, which the salesperson called the Xiaoyun series, specifically designed for hybrids. For daily city commuting, it mostly relies on the electric motor, and you can hardly hear the engine. When driving on the highway, the engine intervention is also very smooth, with a fuel consumption of just over 4 liters. Last week, I went for maintenance, and the technician said the engine has a simple structure, making maintenance costs one-third cheaper than joint-venture cars. An oil and filter change only costs around two to three hundred yuan. What surprised me the most is the exceptionally tidy layout of the engine compartment; even adding windshield washer fluid is hassle-free without having to search around.

Recently, while helping a friend choose a car, I specifically researched BYD's technological roadmap. The engines used in the Song Pro are all based on in-house technology, from the early 1.5T turbocharged engines to the current Xiaoyun plug-in hybrid dedicated engine, achieving a globally leading thermal efficiency of 43%. This self-developed strategy has reduced the overall vehicle cost by 15%, making the final price more competitive. Last year, during a factory visit, I witnessed automated production lines where an engine rolls off the line every 90 seconds, with quality control stricter than some joint-venture brands. Most importantly, these engines can perfectly adapt to the DM-i hybrid system, unlike some brands that assemble foreign components and often encounter compatibility issues.
