Look down on "micro power"? This article will tell you the truth!

The previous article "Reducing emissions and reducing cylinders, eating ugly? Three musketeers screwed up! "has become a new slot. Let's recall that when BMW, Audi, Volvo and other manufacturers launched the 2.0T "micro-power" engine of the B-class car, we began to face it with a joking attitude. But now, they are really not jokes. Because of the current mass production cars, with the arrival of environmental protection laws and policies, the number of four-cylinder cars began to decrease slowly, and three-cylinder cars gradually occupied the market because of compactness and low maintenance cost, and A-class cars began to be used. However, we returned to the period of "inadaptability" and began to loathe to give up four cylinders ... Although the technology is improving, the engine has entered the era of small displacement and high energy. With the help of turbocharging, the hardware strength of the engine itself is getting stronger and stronger, and the lightweight design of the car body makes the current car more and more energy efficient and fuel consumption lower and lower. But ... here comes the problem! The natural disadvantage of the three cylinders-jitter, has become a slot for many people. Coupled with a higher-level B-class car, if three cylinders are used, it will not only lower the brand level, but also lead to consumer dissatisfaction with the brand.

▲? BMW? B48TU

▲? BMW? G20？ 3? series

Take the B-class BMW 3 Series as an example. When the low-power B48B20D turbocharged 2.0T four-cylinder direct injection engine went on the market, the digital maximum power output was only 1 15. kW( 156？ PS), the maximum torque is 250? Not to mention Nano Volvo, Volvo S60 has a minimum of 2.0T? Drive-E？ Maximum power of T3 engine 120? kW( 163？ PS), the maximum torque is 265? Nano. Maybe we want to laugh at people who buy cars because of such low motivation.

▲? F30？ 3? series

However, as we all know, we were wrong. Due to environmental regulations, manufacturers have to control costs, so the small displacement machine was changed to three-cylinder turbocharging. Why F30? 3 series 3 18 sales are bleak? The reason is that the three cylinders 1.5T of the B-class car, even if the horsepower performance is excellent, is "one cylinder missing", just like this fishbone stuck in the throat of consumers. Coupled with the poor user experience, a word "shake"! It is good to reduce the price while affecting the ride experience, but it reduces the brand image of BMW B. What if the book figures look good? What's more, BMW's 320 has always been the main force in terms of volume. What will happen if BMW 320 is replaced by 1.5T? B38 will inevitably have the same consequences as BMW 3 18i. In this way, consumers will choose cars with larger displacement, and no matter how poor they are, they will not buy such compulsory three-cylinder cars. That's the truth.

In addition, why do I say this is also a cost-saving approach? As mentioned above, the consumer's wish is at least 4 cylinders. If the 3 series is made into 3 cylinders, the manufacturer will definitely invest a lot of money to allocate the best driving state. Will consume a lot of manpower and material resources. Many things have to be optimized to match the characteristics of the whole vehicle. The development cost of vehicle weight, gearbox logic and ECU is very high. If we don't learn the painful lesson of 3 18i market failure, why will BMW develop?

▲? Volvo? Drive-E？ T3？ 3 cylinders

▲? Volvo? Drive-E？ T3？ 4 cylinders

Even for two turbocharged engines with the same power, the engine with large basic displacement often has better torque and better maximum torque output platform. If the small displacement engine will trigger the condition of mixture enrichment for various reasons, then the higher maximum torque and wider maximum torque output platform compared with the large displacement engine can minimize the conditions that trigger the protection of mixture enrichment. If B38 engine with displacement of 1.5 liter is used on the brand-new BMW 320, even if the maximum power of 156 horsepower is reached, it is not difficult for BMW. Considering the whole vehicle working condition, the relatively low torque of 1.5T engine will inevitably trigger the air-fuel mixture enrichment condition frequently. So, it seems unreasonable power output, but BMW gives you four cylinders instead of three. This is something to be happy about. Mature technology, mass production, through optimization and adjustment of the engine, increase the displacement. We still need to worry about people giving us 3 cylinders, 5 series and 3 cylinders, 7 series? So this is why Audi A4L does not give 1.5T, but gives 150 horses a low power of 2.0T. Similarly, Volvo S60' s 163 horsepower is 2.0t? Drive-E？ T3 is also a good example. In addition, the power of the mature 2.0T four-cylinder engine is not enough. Of course, we can optimize the working condition by rewriting ECU after sale! We can naturally remove the conservative power output seal of the engine. The machine is powerful, what are we afraid of?

▲? Huh? Polo？ GTI uses 2.0T? EA888

Another example about VAG can also be related to the description in the previous paragraph. Brand-new type? Why does AW's Volkswagen Pineapple GTI use low-power 200-horse 2.0T? Gen3？ EA888？ R4？ TSI engine. For EA888, everyone will definitely say that this is a great machine. However, why not go to China? The reason is simple: emissions. With such a large displacement of A0, the price difference will widen. Some netizens will take the problem of "golf GTI can't be sold well" one-sidedly. In fact, let's recall that Typ was changed as early as the late European version. 6C pineapple GTI adopts the same 1.8T as Ling Du? EA888？ R4？ TSI, 6R precedes 6C itself? Polo？ GTI this 1.4T? EA2 1 1？ R4？ TSI twin turbocharging (domestic single turbocharging) is very expensive, and it is really meaningless to continue, so Volkswagen's previous generation pineapple GTI was redesigned and sold in Ling Du1.8t.

Then cash pineapple GTI, Volkswagen "reversed" and increased the displacement to 1984? Cc, replacing the previous 1.8T? EA888. It is also like BMW to optimize EA888 by optimizing machine and mass production. In this way, not only the cost is well controlled, but also the demand of automobile players for engine strength is met, which is not a bad thing. However, due to the large displacement of EA888, it is difficult to compete at A0 level in China, so even if the displacement is increased in Europe, the price will not be increased. The x cost of climbing in China is naturally indispensable to AW's 2.0T pineapple GTI.

Seeing this, I hope to pay attention to everyone in the commune and take good care of them to buy micro-power 2.0T? For riders of B-class cars and C-class cars, the horsepower book data is really not as good as our previous cars. However, with more and more strict environmental protection laws and regulations, the large displacement is less and less. The manufacturer seems to have played a joke on us, but in fact, the manufacturer is forced to give us such an answer. We should accept this answer with a smile. For those riders who mention micro-power luxury cars, as long as they are unobtrusive, low-key and restrained, we can properly care about them and make friends with them. In the past, we always looked forward to the future. Now, the future has arrived. We must cherish what kind of car we have and what kind of friends we have. Because next second, we can't predict what will happen.
