Is it possible for Japanese cars to save fuel because they are light?

Are Japanese cars fuel-efficient because they are lightweight?

Personally, I think there are reasons for this, of course, it may be that the fuel utilization rate of Japanese cars is higher, which leads to less fuel consumption and more fuel economy.

This is partly due to this, most notably his CVT gearbox, which is more fuel-efficient because of its continuously variable mode, especially during acceleration, with no power loss.

The light weight and fuel saving of the whole vehicle is only one aspect, and it is also determined by the factor of the engine, and the engine of Japanese cars generally has a higher fuel saving rate, which is also the reason why many people admire. On the basis of ensuring the strength of the body structure, Japanese cars continue to optimize and reduce the weight of the car. Of course, many consumers still think that Japanese cars are not strong.

The fuel economy of Japanese cars is really not as simple as "light car"! You'll understand after reading it.

The engine is efficient and has low power.

Yes, so it's not as secure. And under the current technology, other brands of models are also very fuel-efficient, and it is not necessary to identify the Japanese as fuel-efficient at the macro level.

Japanese cars are famous for breaking when touched, so it is recommended to take a look at domestic and German cars; If the person is gone, you can't enjoy the quality of life no matter what, and the safety of life is related to several families, which needs to be carefully considered!!

1.The quality of the vehicle equipment is low and very light, which makes use of the relationship between self-weight and fuel saving.

2.Engine technology, CVVT VVT is Honda and Toyota's fuel-saving technology. Japanese cars mostly use high-speed engines, and the bore is generally small relative to the piston stroke, which has the consequence that the power is high at high speeds but the torque is relatively small, especially at low speeds.

3.The transmission ratio of the gearbox, the general Japanese car 5 gears 2500 rpm to run to 100km h, other cars need 3000 rpm, so that the Japanese car naturally saves fuel at high speed.

The safety factor does not look at the weight of the car, the light that the car can do is the effort, the engine is also a strength, and the transmission has always been the strength of the Japanese system, many European and American cars have purchased Japanese transmissions, as well as the current popular turbocharging, all of which are Japanese.

Or technology first.

This is one of the factors, as well as its engine and gearbox. It is a combination of reasons

Not exactly.

From my driving experience, the light weight of Japanese cars is one aspect; And it's almost outrageous in terms of weight loss. For example, the Honda Fengfan, the places that can be seen and touched in the cockpit of this car are relatively good, but when you open the engine cover and tail box, you will be very depressed to find how frugal Honda is: the engine compartment sound insulation and heat insulation cotton only gives 50% of the coverage area, and there is no sound absorbing cotton on one side (I heard that the 2017 model directly canceled the heat insulation cotton ......).Even the most fierce Civic, hundreds of thousands of cars are made of insulated cotton!

The metal was directly seen in the tail box, and the carpet was not covered! The engine compartment is empty, and the gap between the water tank and the engine can be 30 centimeters! The lower guard plate of the engine is only half, and the other side is directly a big hole, and the material is still plastic ......Everyone is spraying the rear impact beam, and if there is no rear impact beam, I won't complain......

The gearbox settings of Japanese cars are also very distinctive. The characteristic of ordinary Japanese passenger cars (non-performance cars) is that they are very active in upshifting, and when driving, the throttle is slightly loosened and the gear goes up, but you want it to downshift and overtake? When you press the accelerator pedal halfway, it won't back down, and you have to press two-thirds of the way before you reluctantly back out of gear; But as soon as the foot loosened, it rubbed and went into gear again!

This is extremely speechless. Overtaking on mountain curves is not in the limit gear, and it is basically impossible to overtake.

On the other hand, Japanese cars also have a characteristic of accelerating rapidly in the early stage, but the acceleration ability in the rear is relatively weak. According to the research and development calculations of the island engineers, most of the fuel consumption is used in the low-speed stage at the start, so simply set the transmission ratio of the gearbox to 1-3 gears The transmission ratio is very large, so just give some oil, and the vehicle speed will go up, first of all, it can shorten the early acceleration time, and secondly, after the speed is raised, you can better use the inertia of the vehicle to coast and save fuel, and the third is to fool the novice: you see how fierce my car is speeding up!

It's not a matter of killing other cars of the same displacement and class at all! Let you win directly at the starting line......In fact, in the middle and rear sections, you can only look at the taillights. Of course, professional and semi-professional players such as STI, EVO and Z, as well as God of War, are not included.

At the same speed, the higher the gear, the lower the engine speed, the crankshaft is injected once every two revolutions, according to this calculation, the engine speed is of course the lower the more fuel-efficient, so it is not difficult to understand the design concept of Japan's resource-poor island country: every drop of oil must be carefully calculated, squeezing out the potential of every drop of oil, which is incomparable with the old United States that can not be compared with the V8V10 engine at every turn, the displacement starts, and the local tyrant behavior that cannot be capped, and the United States burns the cheapest and cleanest fuel in the world. Whoever dares to raise the price will beat whom, what the hell is fuel consumption? When have you ever seen an American car tell you about fuel consumption per 100 kilometers?

Lao Mei will only tell you coaxingly: you who care about fuel consumption are not the potential customers ......of our productsTherefore, an upstart like Lao Mei and a stingy ghost like an island country are not on the same starting line at all, and the design concept and R&D route are naturally very different.

There are factors in this regard, and this is not entirely the case, the engines of Japanese cars are more advanced, such as the Earth Dream engine, which has its own advantages. After comparison, it can be found that the Japanese cars of the same level are only about 40 kg lighter than other cars of the same level, which is not enough to save so much fuel.

Hello Part of the reason for Japanese cars is because the body is light and fuel-efficient, and the engine of Japanese cars is very mature, the engine is very fuel-efficient, and the technology is more advanced.

The main reason is the engine, the engine technology is more advanced, and there are also the reasons you mentioned in this regard.

Hello Japanese vehicles pay attention to engine technology, relatively speaking, the engine technology is more advanced, and the overall fuel consumption of the vehicle is lower.

Hello, this is not necessarily, their engines themselves are more fuel-efficient, because Japan's resources are relatively small, so they will pay more attention to energy in this regard, of course, the wagon is soft, light weight is also because of less resources.

The fuel economy of Japanese models is not entirely due to the light weight of the car, which is inseparable from the engine technology and gearbox, and the main technology is more advanced!

This is just one reason, the most important thing is the Japanese engine, the engine technology maturity is very good, so the fuel consumption is economical.

The light weight of the car is one thing, the most important thing is that the technology of the engine and gearbox is good, so it is fuel-efficient.

The light weight of the car has a certain impact, and the most important thing is that the Japanese car has advanced technology, especially the engine and gearbox technology, so it is fuel-efficient.

Hello, the engine technology of Japanese cars is still relatively advanced, and the fuel consumption performance is really good, but the light body is also one thing.

The reason for the fuel saving of Japanese cars has a certain relationship with weight, but the most important relationship is related to advanced technology and good engine technology.

It is true that the wagon of the car is also relatively thin, for the sake of safety, it is recommended that you still consider the European and American cars, the frame is heavy, and the safety performance is high.

Light weight is only one aspect, the quality of the engine and gearbox is the most important, and the design match is also important.

Hello, this car has little to do with the weight of the body, mainly with the engine he designed, the principle is directly related.

Not only this one reason, can only be said to be one of the reasons, not the main reason, the biggest reason is the advanced engine technology.

This has nothing to do with the weight of the body, mainly related to its engine, generally speaking, Japanese cars are still very good, and fuel consumption is not high.

The bigger reason why Nissan cars are fuel-efficient is the matching of the engine and gearbox. Nissan's development is family-owned. If you open the engine compartment, you can barely see a single stray part.

Its family-style development is destined for the Nissan family to have engines, gearboxes and other core technologies. The matching between these core technologies is very important, and the gearbox will always ensure that the engine is in a suitable operating range, ensuring a balance between power and fuel consumption. The core advantage of Dongfeng Nissan is not only that it is fuel-efficient and has a good engine, but that the overall cost of the car is relatively low.

For the same 200,000 car, it is more economical to drive a Dongfeng Nissan car than to drive a German car, including: fuel consumption, maintenance, failure rate and other aspects.

The most fundamental reason for the fuel saving of Japanese cars is that the power system design is very reasonable, and the weight of the whole vehicle is now public information, you can go to the Internet to compare the Japanese and German American cars of the same level, and many Japanese cars are heavier than the German and American cars.

No, because the car is not just because it is light, the most important thing is that the configuration, the engine and the gearbox are matched appropriately, which can ensure the balance of power and fuel consumption. Hope it helps.

Only leeks who don't know how to drive will think so!! One of the simplest questions, is F1 cars fuel-efficient? It's less than 1 ton!

No, the Sylphy is heavier than the Lavida, but the fuel consumption is low, and the CVT gearbox and the low ** motor workmanship characteristics determine the low fuel consumption.

This Japanese car because of the light weight and fuel saving of the vehicle, this is on the one hand, the most important fuel saving is its good gearbox performance, its high transmission efficiency, and low natural fuel consumption.

It can't be absolutely said that because of light mining and fuel saving, Korean cars are also relatively light; I think it's mainly about the engine manufacturing process.

It's true, some people say that Japanese cars have thin skin, no crash beams, etc., I don't object to these, but at the same time, it depends on the collision results of IIHS and NCAP, and everything else is! At the same time, let's not forget Japan's world-leading engine technology, fuel saving is not just about omitting the crash beam.

Hello not quite, the engine design is also reasonable.

This is one of them, the main thing is technology.

The seventy-sixth episode: The flute of the convex hall is poignant, and the poems of the concave crystal hall are sad and lonely.

2.What to think about the weight of the body. First of all, as far as the car itself is concerned, the most advanced technology is now developing in the direction of lightweight, such as the current highest-grade body material is carbon fiber, such as various sports cars, and then aluminum alloy, BMW 7 Series, Audi A8 and the like.

So if you still think that the heavier the car, the more advanced it is, then you are wrong. Secondly, the weight of the body has little to do with safety. People with a little common sense know that the body structure is the most important factor in determining safety, which is what we usually call the body-in-white.

Other padding has little to do with crash safety, but it does determine the weight of the vehicle. The Japanese are usually light on top of the outer padding. The most typical is the door filler, why many people think that the door closing sound of European and American cars is very heavy, it is actually just a relatively thick filling plastic, which strengthens the impression of heaviness.

Moreover, low-priced Japanese cars are indeed lighter, and in the field of daily family cars of more than 100,000 or 200,000 yuan, Japanese cars are indeed lighter than European and American cars of the same level. This also has disadvantages, mainly low-speed collision repairs will be expensive, and daily small hanging wipes are more obvious. So many people see that at the scene of a general scratch car accident, the loss of Japanese cars looks a little more serious.

This is not the case with high-end Japanese cars. But the positioning of low-priced Japanese cars is cheap, fuel-efficient and easy to use, and nothing else is his mission.

Japanese cars have been touted as having their engines technologically advanced and fuel-efficient, what VVT

i, VTEC, etc., to put it bluntly, is the variable timing valve adjustment technology, that is, according to the driving state by adjusting the intake volume of the valve to control the fuel consumption. Is this really a huge saving on fuel consumption?! Definitely!

In fact, this can only blind the layman. Just think about it. Nowadays, social energy is becoming more and more tight, and the standard of a good engine is to exert as much power as possible with as little fuel consumption as possible.

Torque distance, this is the goal pursued by any manufacturer. In today's world, several famous large companies that produce automobiles, such as BMW, Mercedes-Benz, Volkswagen, General Motors, Ford, Toyota, etc., have basically the same level of engine research and development, that is to say, the level of several brands of engines is relatively close, and the fuel consumption level of engines with the same displacement and power is also comparable. Among them, German brands such as BMW and Mercedes-Benz are slightly ahead.

Every year, European and American brands account for almost the vast majority of the world's top ten engines selected by international automotive magazines. It can be seen that the argument advocated by the Japanese that the engine technology is advanced and fuel-efficient is not valid.

How can the same displacement, close power be more fuel-efficient? According to the laws of physics, the only way is to reduce the weight of the body. The chassis and assembly can not be less but more, so we can only make a fuss from the steel used in the body.

Japanese cars save fuel by thinning the thickness of the steel on the body and reducing the weight of the vehicle. This is easy for those who have driven a Japanese car to understand, driving at high speed is easy to drift, the higher the speed of the steering, the lighter it is, and it is not as stable as European and American cars. Some people will ask, if the thickness of the steel is reduced, how can the hard standard of the crash test be passed?

Quite simply, the crash test is not about the hardness of the steel, but about the absorption of the vehicle.

The ability to impulse. The front of a Japanese car collapses and breaks quickly in the event of a collision, and the damage to the front of the car protects the integrity of the cab and allows it to pass the crash test. In reality, in accidents where Japanese cars collide with European and American cars, the damage to the body of Japanese cars is often much more serious.

In normal driving, especially at high speeds, this collapse and fracture is fatal. That is, a veritable tofu truck.

Therefore, if you don't think you have a long life, it is recommended not to buy a Japanese car. Since you can afford to buy a car, don't save those few gas dollars, or life is the most important.
