This question is really asked... As long as you run diligently and maintain properly, three or four hundred thousand kilometers is not a problem. At the current level of car manufacturing, the life of the engine is not worried at all, but the gearbox and other components are more delicate. You know, domestic family cars are not driven to scrap, but scrapped by emission standards.
The durability of the engine
Every car company has to carry out durability tests when developing engines, so the 100,000-kilometer mileage is not much pressure for a mature engine.
For example, Changan engine, each Changan engine must go through 25,000 kilometers of uninterrupted reliability test, each car needs to run at least 1.4 million kilometers to assess whether it is qualified.
GM's eighth-generation Ecotec 1.3T engine, with a cumulative test mileage of 4.65 million kilometers, has experienced 4,500 meters of alpine, plateau, high heat, high humidity, high corrosion road conditions, spanning different regions and different road conditions, in order to mass production.
Therefore, for an engine, it is necessary to complete a variety of extreme conditions of durability testing, ordinary household conditions for an engine is really nothing.
How about the Toyota 2.0T engine
Although Toyota does not have many turbocharged engines, the technical level of this 2.0T engine is not bad, first of all, it is "switchable dual-cycle technology", when strong power is needed, the system adopts the mode of Otto cycle to ensure sufficient power. At low loads, switch to the Atkinson cycle to maximize efficiency gains.
In addition, this engine also uses Toyota's very famous D-4S dual injection technology, which uses the current advanced in-cylinder direct injection technology to ensure output efficiency at normal output, and uses intake manifold injection at low output. For engine life, the 8AR-FTS engine is equipped with a water-cooled intercooler and an integrated exhaust manifold in the cylinder head, both technologies that achieve optimal intake air temperature and extend turbocharger life.
All in all, as long as you are properly maintained, running 200,000 kilometers is not a problem at all, many taxis can even travel 1 million kilometers, and what really determines the life of the vehicle is the policy.
