Once the natural suction engine is almost the first choice of every car company, many brands are also because the natural suction engine for themselves to accumulate a lot of good reputation, in the early years of the family car point of view of natural suction and turbo engine compared, self-priming engine is to be more reliable than the turbo engine, durability is better, even if the turbine is the way today, the self-priming engine is still not losing the turbo engine, and these two engines do not have a clear good or bad point, the reason why today the turbine engine can become the main force, To say that it is because of energy saving and emission reduction, to the novel with the turbine technology more and more mature, especially small displacement engine, research and development costs "relatively" will be lower, and can be used in a machine and multiple vehicles, now most of the models we can buy are turbocharged engines, usually the urban driving power feeling is indeed better than the self-priming under the same displacement, but these are not absolute, some models use although the turbine engine, can belong to the "turbo decompression" these engines with turbines are even weaker than the self-priming power, Today to give you a few turbo decompression models, here to emphasize that it is not that these cars are not good, will be said in detail later.
Isn't 2.0T the golden power?
In the increasingly stringent emission standards, as well as energy saving and emission reduction environment, 2.0T has become a large displacement of this era, and 2.0T is also the golden power of many displacements, but not all 2.0T can be called golden power, as far as the following cars are concerned, they all belong to the turbo decompression model, BMW 320, Audi A4L 35, Volvo S60 B3.
It can be said that the power parameters of these three cars are not as strong as some 1.5T models, and these three cars are all luxury brands, in fact, as far as power is concerned, manufacturers want to improve as simple as we step on an ant. But why manufacturers still do this, let's talk about it specifically.
Why manufacturers deliberately reduce power
From the above table, it is not difficult to see that the power of these three cars is obviously deliberately adjusted by the manufacturer, there are several reasons, first from these three models, BMW 3 series, Audi A4L, Volvo S60, these three cars can be said to be the brand entry-level sedan, although there are also lower than them more entry-level cars, such as 1 series sedan, A3, etc., but comprehensively from the product point of view, these three cars are the mainstream entry models of the brand, since it is an entry-level model, it will definitely take into account the amount of walking, Want to go the price of the need to be tempting enough, in order to reduce the model entry price, the manufacturer will be through the adjustment of the power, displacement, configuration and other aspects to achieve the purpose, these three cars are basically through the power to achieve a price reduction entry price, like Audi A4L and Volvo S60 entry only one configuration, the purpose is not to sell the car car, even if you go to the 4S shop to ask most will not have a car, unless you really want this car, 4S shop and manufacturers book, waiting for the car time will be relatively long, There are very few people who can buy this most entry-level configuration, and its main role is to reduce the price and attract consumers through the entry price, especially the BMW 320 and Volvo S60, the lowest price has dropped to about 290,000, giving consumers an illusion that they can buy luxury brands without 300,000.
So some people may not believe, in reality I have met a lot of such people, only look at the lowest price, think that the guide price is the final landing price, in fact, people who really understand the car are not as many as imagined, most of them still only know a little fur. The manufacturer has captured the heart of everyone who thinks that the guidance price is the landing price, Secondly, the manufacturer does not want to adjust the 2.0T parameter so ugly, the reason is still in everyone's public opinion, like 18-19 between this section of A4L entry model is not 2.0T but 1.4T, the last generation of BMW 3 series, as the entry of the 318 uses a 1.5T three-cylinder engine, the previous generation of Volvo S60 is also 1.5T engine is good in a four-cylinder, it can be said that at that time these cars were often taken out on the Internet to ridicule, on the road to see not let go, the most powerful spray is still 318, it is no wonder that a car with a sports label uses a 1.5T three-cylinder engine So that the visibility of this car is even lower than the M3, the 1.4T Audi A4L is also not good to go there, even if it is a longitudinal engine, but many people will still say that the 1.4T A4L is a hardcover Sagittarius.
Reduce R&D costs
Cost reduction is the ultimate goal of the manufacturer, not by the production of entry-level engines to reduce costs, not to mention the 320 and 35 A4L to buy people are also relatively small, basically according to the order production, the cost reduction mentioned here is reflected in research and development, as an entry-level power, the simplest way is to adjust the engine hardware, if the development of a new engine to match, not only the cost is not saved, but will pull up the overall price of the model, in the sales volume slowly amortized the cost of the vehicle, Obviously, most car companies will choose to modify the engine hardware to achieve their goals.
Low-power engines can be brushed into high-power parameters
At first, my idea was the same, thinking of buying a model with the same engine at a lower price, just a low point of power, and later by brushing the ECU you can achieve high-power parameters, may be greater than high-power horsepower, in fact, it is not so simple on the surface, take the 3 series, 320 and 325 use B48 engines, but there is still a big difference in the periphery and parts, the piston of the high-power engine, the crankshaft can withstand more torque, and the turbo pressure will be different. Even if the engine horsepower is adjusted to the same parameters as high power through the ECU in the later stage, but the engine will have hidden dangers such as cylinder bursting, if the budget can not reach the high-power model, either honestly choose to drive low power, or give up vanity to choose a more in line with the needs of the model.
brief summary
Although these three cars belong to the turbo decompression engine, the power parameters are not advantageous, but there is no discount on the displacement, but also to maintain the dignity, for consumers, buy a car, especially luxury brands, turbo decompression methods, compared to reducing the displacement is easier to be accepted by everyone, but Mercedes-Benz, even if this method consumers also do not buy it, each model, in each consumer's mind has a positioning of their own, most people will not choose the lowest match because of the entry price reduction, Buying a car is ultimately combined with the actual use, especially horsepower, which everyone cares about, vehicle horsepower is like the storage space we look at when buying a mobile phone, everyone knows that the more the better, but the more money that needs to be paid, the more money that needs to be paid, writing this article is not to let everyone buy this car, but in the face of the manufacturer's use of turbine pressure reduction and displacement methods You will choose which, but the vast majority of people should not choose both, because the budget of 300,000 why give up more things for a brand.
