What engine does the BYD Song Pro use?

[VonOwen]

BYD Song Pro is equipped with a turbocharged engine with the model code BYD476ZQB, which has a displacement of 1.5 liters. This engine delivers a maximum horsepower of 160 hp, a maximum power of 118 kW, and a maximum torque of 245 N·m. The maximum power speed is 5200 rpm, and the maximum torque speed ranges from 1600 to 4000 rpm. Below is a brief introduction to the BYD Song Pro: (1) The BYD Song Pro is a compact SUV produced by BYD Auto. In terms of body dimensions, the BYD Song Pro measures 465018601700 mm in length, width, and height. (2) In terms of transmission, the BYD Song Pro uses a 6-speed dual-clutch transmission across all models. (3) In terms of drivetrain, the BYD Song Pro features front-engine, front-wheel drive.

I drove my friend's Song Pro, which is powered by BYD's own Xiaoyun 1.5T turbocharged engine. The power is quite impressive, with a maximum output of 136 kW, making overtaking in the city a breeze. The engine features high-pressure direct injection technology, and the official fuel consumption is around 7 liters per 100 kilometers. My friend's actual usage is about 8 liters, which is acceptable. The key is that the engine is well-matched with the 7-speed dual-clutch transmission, providing smooth gear shifts without noticeable jerks. I heard the new model also added a variable geometry turbocharger, delivering immediate response when you step on the gas, unlike the old turbos that took a few seconds to spool up. Maintenance isn't too expensive either, with minor services costing just over 400 yuan.

The Song Pro comes in both fuel-powered and hybrid versions. The fuel-powered version is equipped with the Xiaoyun 1.5T turbocharged engine across the entire lineup. During my test drive, I specifically noticed that the torque reaches 288 Nm at 1800 rpm, making it very responsive at traffic lights. Under the hood, you can see an all-aluminum cylinder block, which provides excellent heat dissipation—even on long drives, the coolant temperature gauge barely moves. Some people complain that turbocharged engines are prone to carbon buildup, but this one features intake tumble optimization technology; after 5,000 kilometers, my spark plugs still looked clean. The hybrid DM-i model swaps in a 1.5L naturally aspirated engine with a claimed thermal efficiency of 43%. It usually functions as a range extender, delivering impressive fuel economy, though the engine noise during hard acceleration is more noticeable compared to the fuel-powered version.

If you're interested in engine technology, the Song Pro's 1.5T model is quite impressive. I've disassembled the old cylinder head - its twin-scroll turbo design effectively separates exhaust pulses, showing virtually no lag at low RPM. The valves feature hollow sodium-filled construction, offering significantly faster heat dissipation than solid ones. The cylinder block uses low-pressure cast aluminum, saving over ten kilograms compared to cast iron. The oil pan even incorporates dedicated baffles to prevent oil sloshing during cornering. The hybrid version's 1.5L Atkinson-cycle engine is even more remarkable, boasting a 15.5:1 compression ratio with mirror-finish piston coatings to reduce friction. BYD has clearly put serious effort into these engineering details.

I've driven the Song Pro for three years, and what satisfies me most about this car is the engine's reliability. The 1.5T engine has now clocked over 60,000 kilometers, and apart from regular oil and filter changes, I haven't even needed to replace the spark plugs. I remember last winter at minus 15 degrees Celsius, it started right up with just a turn of the key. The cooling system is intelligently designed – even after half an hour of summer traffic jams, the water temperature never exceeded the midpoint. As for drawbacks, the noise is a bit loud during the first thirty seconds of a cold start, but it quiets down once the lubrication kicks in. I heard the new model has optimized the engine mounting brackets, significantly reducing vibrations. Maintenance costs are quite affordable too; replacing the timing belt out of pocket only costs around 800 yuan.

As a hybrid car owner, my Song Pro DM-i is equipped with a 1.5L naturally aspirated engine. This machine is fascinating—it primarily relies on electric motor drive, with the engine only kicking in when the battery is low or during high-speed cruising. The dashboard shows the engine RPM consistently maintained around 2000, its most efficient range, completely decoupled from the transmission. It drives like a pure electric car but can cover over 1,000 kilometers on a full tank and full charge. The most amazing part is its EGR cooling system, which precisely controls exhaust gas temperature, delivering quick warm air in winter. It’s much quieter than pure gasoline cars, with no steering wheel vibration even when the engine starts—truly impressive engineering calibration.
