Is the Original BYD Engine Good?

[MacBrynlee]

BYD Yuan's engine is the BYD473QE, which offers good overall performance. Below is an introduction to the original BYD engine: 1. The BYD473QE engine is a brand-new 1.5L golden displacement all-aluminum engine independently developed by BYD, with a maximum power output of 80kW and a maximum torque of 145Nm. 2. This engine features advanced VVL (Variable Valve Lift) technology and an EGR (Exhaust Gas Recirculation) system, characterized by lightweight and eco-friendly design, high efficiency and energy-saving, low-carbon and clean operation, as well as smooth and comfortable performance. It represents BYD's commitment to the global trend of low-carbon and environmental protection.

I've driven the BYD Qin hybrid and the F3 gasoline version, both with original engines, and they felt quite good overall. What satisfied me the most was their reliability. For example, with the Qin, the engine never had any major issues over several years, starting quickly with responsive throttle. Fuel consumption is average, around 7-8 liters per 100 kilometers in city and highway driving—not particularly fuel-efficient but better than some brands. Noise control is slightly lacking, with some humming at high speeds, though turning up the music covers it. Maintenance costs are low, with oil and filter changes at the dealership costing just a few hundred yuan, unlike luxury cars that burn through money. Overall, for daily commuting, it’s sufficient, and the low failure rate is a plus, though don’t expect the explosive power of imported engines. BYD’s hybrid technology has since been upgraded, with pure electric mode being noticeably more fuel-efficient, so I’d recommend it to budget-conscious friends.

As a frequent long-distance driver, I pay close attention to engine performance details. BYD's 1.5T original engine performs stably in most models, providing sufficient torque output at startup and effortless hill climbing. After accelerating to 80 km/h, the power becomes slightly subdued—not as aggressive as turbocharged models, but adequate for family use. Maintenance records show good durability; I've driven the Tang fuel version for over three years without major engine repairs, though oil consumption is higher than expected. Overall, it offers high cost-effectiveness with affordable parts and easy-to-find repair services. Fuel consumption is average for its class—quick in sport mode but more economical when switched to eco mode. The downside is slightly higher noise levels, especially during cold starts. New owners are advised to perform regular maintenance and use high-quality oil to extend engine life.

Fuel efficiency was my top priority when choosing a car, and BYD's engine pleasantly surprised me in this regard. Having driven the Song Pro model with its factory-equipped 1.5T engine, I averaged 6.5L per 100km in urban driving, only reaching 7-8L when using air conditioning or in traffic jams - more economical than many competitors. The power delivery is smooth, with effortless performance at low RPMs, making it ideal for daily commuting. Environmentally, it meets emission standards with minimal pollution during operation, though the noise level during acceleration is noticeably higher than electric vehicles. Maintenance is straightforward - just purchase an OBD scanner to diagnose issues yourself. In summary, it excels in economy and daily usability, with no instances of abnormal stalling or malfunctions, making it worthy of long-term ownership.

The maintenance cost of BYD engines is quite satisfactory to me. Genuine parts are affordable, and an oil and filter change at the 4S shop only costs a few hundred yuan. There have been no issues with oil burning. The durability is strong; after five years of driving the S6 model, the engine still runs normally, and just adding some lubricant when the noise gets loud alleviates the issue. The failure rate is low, and the design is simple and easy to repair. For example, if the belt loosens, adjusting it yourself can solve the problem. The fuel consumption is moderate, making it suitable for long-distance driving. However, it's advised not to modify it randomly as it could affect its lifespan. Regular check-ups can prevent minor issues.

From market feedback, many BYD owners praise the durability of the engines. Based on online reviews, most people report that Qin or Han fuel versions run for years without issues, with urban fuel consumption around 7L. The drawbacks are slightly slower acceleration and higher noise levels. Low maintenance costs are key, with parts being easily available and affordable. After long-term use, the engines remain robust and not overly sensitive. While BYD's technology may not be top-tier, it is reliable and suitable for budget-conscious users. It's recommended to test drive before purchasing to get a firsthand experience.
