The engine is the most core technology in the car, without the engine technology, it is difficult for the car company to develop for a long time. As the world's number one car company, Toyota's engine technology has been recognized worldwide. In the two major auto markets in North America and China, Toyota motor vehicles are far ahead in sales.
But Toyota seems to have a fondness for naturally aspirated engines, and at a time when various car companies are switching to turbocharged engines, Toyota is still unmoved, and the engines used in mainstream models are still naturally aspirated engines. The exception is the Toyota Corolla, which is powered by a 1.2T turbocharged engine. Why doesn't Toyota install turbo engines on other models because the technology is not good?
Toyota is not without turbocharged engines, the old crown, Toyota Highlander have been equipped with 2.0T turbocharged engines. It's just that Toyota shinobi is not in the turbocharged engine, so this 2.0T turbocharged engine has not been updated for a long time, and the technology is relatively backward.
Toyota's reluctance to use turbocharged engines is also for some reason. If Toyota abandons self-priming engines and uses turbocharged engines, its proud hybrid technology will be zero.
Toyota has always taken hybrid technology as the core of its own development, some time ago, Japan announced that it will develop into the head of electric vehicle Toyota, Toyota Akio expressed opposition, believing that the development of pure electric vehicles will destroy Japan's economy.
Is his opposition to the development of pure electric vehicles really for this reason? Insiders feel that this is not. Toyota has been working on hybrid technology and has not had a layout in the field of pure electric power. Now abandon hybrid directly to develop pure electric vehicles, then his efforts for many years have been wasted.
Toyota is a profit-oriented enterprise, and its control of costs has reached the point of excellence. A mature naturally aspirated engine is put together with a turbocharged engine that it does not have much certainty about, and Toyota will never choose a turbocharged engine that it is not sure of.
So why did it give the Corolla a 1.2T turbocharged engine? The root cause is still to reduce costs.
The 1.2T turbocharged engine used on the Corolla is not Toyota's own technology, but the one it traded for hybrid technology and BMW. Although the power performance of the 1.2T turbocharged engine is not as good as that of the 1.5-liter naturally aspirated engine, its torque and maximum torque range are more dominant.
The maximum torque of the 1.2T turbocharged engine is 185 Nm and the maximum torque speed is 1500~4000rpm. The maximum torque of the 1.5-liter naturally aspirated engine is 148 Nm, and the maximum torque speed is 4600~5000rpm, and the fuel consumption of both is basically around 5.5L.
The use of turbocharged engines can make the vehicle get more power, while saving fuel consumption, which is very much in line with the needs of Chinese people. Toyota equipped the Corolla with a 1.2T turbocharged engine, also to cater to the preferences of the Chinese people, otherwise how did Toyota Corolla become the sales champion in the compact family car?
Comments:
Toyota's naturally aspirated engine technology is in full swing, but turbocharging technology is really not satisfactory. If you switch to a turbocharged engine, it will lead to an increase in the cost of building a car, which is obviously not Toyota's style.
