What engine is used in the BYD G3?
3 Answers
The BYD G3 is equipped with a 473QB engine, with a displacement of 1.5 liters and an output power of 79kW. Below is extended information about the BYD G3: 1. The BYD G3 features an all-aluminum engine, adopting a lightweight, high-compression ratio design that is compact in size, powerful in performance, fuel-efficient, and operates with low noise. 2. The engine has a long stroke, providing excellent low to mid-speed power, with torque exceeding 130N/m at 2400r/min and a peak torque of 140N/m. 3. The timing system uses a silent chain, which is quiet and maintenance-free, and the connecting rod employs advanced fracture splitting technology. 4. The engine exhibits the characteristic of high torque at low speeds. From the external characteristic curve, it reaches its first torque peak of 134N/m at 2800 rpm, while the 4G15S reaches its first torque peak of 124N/m at 3000 rpm, demonstrating the feature of high torque at low speeds.
We veteran BYD G3 owners all know this model mainly comes with two engine types: First is the 1.5L naturally aspirated version equipped with the BYD473QB engine - exceptionally fuel-efficient for city driving, a full tank can last nearly half a month. Second is the 1.8L version with BYD483QA engine, delivering stronger highway performance. Both feature aluminum cylinder blocks with chain drive systems, far more durable than timing belts and easier to maintain. Earlier base models occasionally used Mitsubishi's 4G15S engine, though these are rare. Maintenance tip: watch out for spark plug water intrusion - my neighbor learned this the hard way with a 2,000 RMB repair bill.
I remember researching this when helping a friend check out a used G3 before. The car's powertrain mainly features their self-developed 1.5L or 1.8L engines. The 1.5L is suitable for daily commuting, with 107 horsepower and VVL variable valve lift, fuel consumption stays around 7L/100km. The 1.8L has a larger displacement but more advanced technology, using Bosch electronic fuel injection system. The key point is its excellent noise insulation - with windows closed, you can barely hear the idle sound. However, older models need attention on throttle carbon buildup, especially for city driving with frequent traffic jams. A cleaning costs just 200-300 RMB and can save significant fuel expenses.
