The Corolla 1.2t engine is a four-cylinder engine produced by Tianjin FAW Toyota Engine Co., Ltd., and is classified as a domestically manufactured engine. The Corolla 1.2t engine model is 9nr-fts, with a maximum power output of 85 kilowatts, a maximum torque of 185 Newton-meters, and a maximum horsepower of 116. For daily maintenance of the Corolla 1.2t engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard being no lower than the requirements specified by the manufacturer. Regularly replace 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 issues. To prevent malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve 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. A small amount of sludge remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

I've been driving a Corolla 1.2T for over two years now, and it's been extremely reliable for my daily commute. The three-cylinder engine delivers smooth acceleration in city driving, with an average fuel consumption of just 5.7L/100km. The turbocharger responds quickly even in traffic jams, and the auto start-stop system helps save fuel at red lights. In terms of vibration, Toyota's new technology makes it barely noticeable. Occasionally, it lacks a bit of power when overtaking on highways, but it's perfectly adequate for daily use. Maintenance costs are reasonable—I just change the spark plugs and engine oil every 10,000 kilometers. The spacious interior is great for families, and the overall value for money is excellent. As someone who commutes frequently, I really love it.

As a car enthusiast, the Corolla 1.2T's three-cylinder engine is cleverly designed. It uses turbocharging to compensate for the small displacement, offering agile city acceleration and low fuel consumption, averaging 6L/100km. Strong low-end torque makes it suitable for short-distance driving, paired with a smooth and quiet CVT transmission. Although inherent three-cylinder characteristics may cause slight vibrations, Toyota's balancing system controls it well. Compared to four-cylinder engines, it's lighter, improving fuel efficiency but slightly weaker in high-speed performance. Regular air filter checks are recommended to maintain performance. The compact engine layout enhances practicality, making it cost-effective and reliable for long-term use.

I prioritized environmental protection and chose the Corolla 1.2T. Its three-cylinder engine is fuel-efficient with low emissions, reducing fuel consumption to 5.5L/100km. The turbocharger provides sufficient starting power despite the small displacement. It operates quietly in urban areas with quick response, minimizing carbon footprint. The drawback is slightly louder noise during cold starts, which improves after warming up. Easy to maintain and suitable for eco-conscious individuals, it's perfectly adequate for daily commuting.

For beginners, the Corolla 1.2T is a great choice with its easy-to-handle three-cylinder engine and fuel efficiency. The automatic transmission makes city driving effortless. Its spacious interior and easy parking are beginner-friendly. The downside is slower acceleration when fully loaded, but it's fine for solo driving. Maintenance is affordable—I service it every six months at Toyota, where service is prompt and cost-effective. Overall, it's a reliable pick for new drivers.
