Corolla has a history of 50 years since it was listed in 1966, and has undergone 10 changes. From the first generation of 1.1L, it gradually upgraded to 1.2L, 1.3L, 1.4L, 1.5L, 1.6L, 1.8L, 2.0L and even 2.4L in the North American market.
As the latest domestic model, the 11th generation Corolla has four displacement options, 1.2T, 1.6L, 1.8L and 1.8L hybrid engines. Then, the maintenance cost of these four models in the later period must be the most concerned by users when buying a car. Is the turbine the most expensive to maintain? Dual-engine hybrid has the lowest fuel consumption? After reading the article, I believe you have your own decision. (Because the attention of 1.8L model is low, it is not discussed in this article.)
● Warranty/maintenance cycle
Corolla’s entire vehicle is guaranteed for 3 years or 100,000 kilometers (whichever comes first). In addition, the warranty period of Corolla Twin Engine is 8 years or 200,000 kilometers (whichever comes first). In addition, since 2014, the maintenance cycle of Corolla has been extended from 5,000 km to 10,000 km.
The maintenance cycle of naturally aspirated engine, hybrid engine and supercharged engine are all 10,000 kilometers. In actual maintenance, some 4S shops may recommend shortening the maintenance interval on the grounds of poor road conditions in China, but I think it is no problem to use fully synthetic 10,000 kilometers for maintenance once for general road conditions.
● Maintenance price
It is rumored that the maintenance price of supercharged models is much more expensive than that of naturally aspirated models. This is not wrong, but it is not rigorous. Because supercharged vehicles usually have higher requirements for engine oil, at least semi-synthetic or all-synthetic engine oil should be used. Naturally aspirated vehicles have lower requirements for engine oil, and mineral oil can meet normal driving needs. But if you use the same synthetic engine oil, the maintenance price is almost the same.
There is little difference in maintenance price among the three displacement models. The maintenance accessories of the 1.2T and twin-engine models are exactly the same (the oil consumption is slightly different, which can be ignored), and the 1.6L model is only different in the air filter, which is cheaper than the other two models in 32 yuan. Because the air filter element only needs to be replaced once every 40,000 kilometers within 60,000 kilometers, the total maintenance cost within 60,000 kilometers is only cheaper than that of supercharged and twin-engine models in 32 yuan.
There is another detail. Because of the kinetic energy recovery system, the dual-engine model will have the function of lightly stepping on the brakes when driving at low speed. Therefore, the frequency of disc replacement is longer than other models.
● Fuel consumption
According to the data of car home netizens’ word of mouth, the fuel consumption of the 1.2T model is.7.3L/100km, and the fuel consumption of 1.6L vehicle is8.1L/100km, the fuel consumption of twin-engine models is4.7L/100km (all comprehensive fuel consumption). It is worth mentioning that the motor operation of the twin engines can save a lot of fuel when driving under urban congested roads, while the fuel consumption is similar to that of ordinary gasoline vehicles when driving at high speed.
From the above data, the annual fuel cost difference between the 1.6L model with the highest fuel consumption and the twin-engine model with the lowest fuel consumption is about 4,000 yuan, and the 1.2T model is about 1000 yuan cheaper than the 1.6L model (calculated by driving 20,000 kilometers a year). The more kilometers you drive, the greater the fuel cost difference.
The higher the oil price, the more obvious the advantages of dual-engine. Before the problems of short battery life and difficult charging of most pure electric vehicles are solved, the hybrid electric vehicle is the best "returning weapon".
● Summary
Compared with the most concerned 1.2T GL (priced at 119,800 yuan) and the twin-engine 1.8L CVT Pioneer Edition (priced at 139,800 yuan), the twin-engine car is 20,000 yuan more expensive, and the configuration of engine anti-theft, head airbag, heat insulation glass,, and shift paddles is more fuel-efficient and quite cost-effective.
I believe that after reading the article, everyone has a steelyard in mind. If your mileage exceeds 20,000 kilometers a year and your budget is sufficient, then the double engine is undoubtedly the best choice, and the low fuel consumption in the later period will make you return to your original position quickly. As for how to choose 1.2T and 1.6L, different people have different opinions. The advantage of 1.6L engine is that it has a large number of vehicles, and the later maintenance is convenient and easy, while the advantage of 1.2T engine is fuel economy and lower emissions. However, small-displacement turbines are the current trend. If I were you, I would choose the latter, because compared with the 1.6L model, it is only 2,000 yuan more expensive, and I enjoy the updated technology and environmentally-friendly low-carbon life.
