Are the A25A and A25B engines imported?

[LaKai]

The Camry A25A engine and A25B engine are imported. The A25A engine is used in fuel-powered models, while the A25B engine is used in hybrid models. The Camry A25A engine has a maximum power of 154KW, a maximum torque of 250Nm, and a maximum horsepower of 209Ps. The A25B engine has a maximum power of 131KW, a maximum torque of 221Nm, and a maximum horsepower of 178Ps. For daily maintenance of the Camry A25A and A25B engines, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine problems. To avoid malfunctions, the oil should be changed regularly based on usage conditions, and the oil level should be kept moderate. When the 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 the oil cannot pass through, the filter may burst or the safety valve may open, allowing the oil to bypass the filter 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 particles from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it 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 properly but also extends the overall lifespan of the radiator and engine.

This issue depends on the situation. As someone with over 20 years of experience in car repairs, I've seen many cases. The A25B engine used in imported Lexus models is definitely originally imported, but domestically produced Toyota models like the Camry mostly use the domestically manufactured A25A engine. Domestic engine parts are cheaper and easier to find, making repairs much more convenient. Just the other day, I encountered a Camry owner needing spark plugs, and we had them in stock right in the warehouse. Repairing imported engines is more troublesome, as waiting for parts can take up to half a month. In reality, the quality of domestic engines isn't bad—they're all manufactured to Toyota's standards. We've disassembled and compared them, and the precision of core components is basically the same. If you particularly care about the imported status, choosing a Lexus is definitely the right choice.

I'm in the parallel import car business and am particularly sensitive about engine origins. The A25B hybrid engine is indeed all imported from Japan, mainly fitted in imported cars like the Lexus UX. The A25A is more complicated—those used in domestically produced Toyota models are mostly assembled at the Tianjin engine plant, but some Middle East-spec Prados also come with Japan-made A25As. The key is to check the first three digits of the VIN: JT means Japan-made, while LV indicates domestic production. Last year, I helped a client check an Avalon—clearly a domestically produced car, but someone insisted it had an imported engine. Turned out the engine number started with LFM, confirming it was domestic. Honestly, Toyota's localization level is very high now—there's really no need to obsess over the origin.

When I first bought a hybrid car, I researched this topic. My Lexus UX250h uses the A25B engine, and the mechanic said it's purely imported during maintenance. However, a friend who bought a Camry Hybrid was explicitly told by the 4S dealership that it uses the domestically produced A25A engine. There isn't much difference in driving experience between the two—both have smooth hybrid transitions. In fact, the domestic engine has an advantage. Last time I went for maintenance, the oil filter for the imported engine had to be ordered, while parts for the domestic model were readily available in stock. I recommend checking the "Certificate of Conformity" in the vehicle documents—the engine's production origin is clearly stated. Don’t be misled by dealers claiming "imported technology"; the actual production location matters most.
