I opened the 2.0 Camry bought by a friend, and I felt a little fleshy. I think the power is greater than Volkswagen1.4t. Why?

This is not a feeling, but the Camry 2.0l model is really not as fast as the Volkswagen 1.4t model.

The zero acceleration time of Volkswagen 1.4t models is mostly around 8.6 seconds, while the zero acceleration time officially announced by Honda's 10th Civic is only 8.7 seconds, which can be seconds! 18 Camry's zero percent acceleration time is almost close to 12 second. 19 Camry's engine has been upgraded, and the acceleration is slightly faster, but the zero percent acceleration is also close to 10.5 second. So it's true that Volkswagen 1.4t is faster than Camry 2.0l

Friends who don't believe it can check online, and you will find that almost all websites don't mark Camry's zero-hundred acceleration time. Why? Because this is not Camry's selling point, Toyota is afraid of being laughed at, so Camry's zero-hundred acceleration time is not provided for all websites' reference. Otherwise, take Camry's engine thermal efficiency as an example, Toyota's related publicity has long been blown to the sky, I hope everyone on earth knows.

Is it fast? It's not just about power. For example, the maximum power of Camry 2.0l engine is 13 1kw, while the maximum power of Magotan 1.4t model is only 1 0kw, so many friends who don't know the truth will think that Camry 2.0l, Asian Dragon 2.0l and lexus es200 are all better than Magotan/. I've really seen someone say that lexus es200 is faster than Mercedes-Benz 1.5t! But this is not the case.

Looking further down, Camry 2.0l maximum horsepower 178, Magotan 1.4t maximum horsepower 150, Camry 2.0l maximum horsepower 2 10, Magotan 1.4t maximum horsepower 250. Although horsepower is not dominant, the maximum torque of Magotan 1.4t is larger than that of Camry 2.0l, but is it fast or not? The first thing to look at is torque.

And because it is a turbocharged engine, the maximum torque speed of Magotan 1.4t is 1750-3000 rpm. Within this engine speed range, Magotan 1.4t can exert the maximum torque. The maximum torque and speed of Camry should be 4400-5200 rpm. For example, if you start at the same time, Magotan 1.4t will go all out halfway, and Camry will have to wait for a while to reach the finish line before going all out, which is naturally not as fast as Magotan.

However, the Camry 2.0l will start faster than the Magotan 1.4t, because before the turbine intervention, the Magotan 1.4t is equivalent to the naturally aspirated car of 1.4l, but in a few seconds, the Magotan 1.4t can surpass the Camry 2.0l and keep ahead.

I'm half the owner of Camry 2.5, and I've also driven a 1.4T Magotan. Realistically speaking, in terms of extreme dynamics, let alone the Camry of 2.0. Even the Camry of 2.5 is not as strong as the Magotan of 1.4T. Looking at a home test, the Volkswagen1.4t high-power engine with a nominal horsepower of 150 is installed on a Magotan, and the acceleration is 8.58 seconds at 0- 100km/h, while the Camry 2 with a horsepower of 209. Camry still can't beat Magotan1.4t. This small-displacement dry dual clutch, even if the parameters are ahead, can suppress the speed ejection from the beginning, but it can't fully exert its strength from the beginning. It really surprised me. Why? I can only think that either Volkswagen is too conservative or Toyota is too grandiose. Anyway, according to the standard of 20 19, a self-priming medium-sized car version 2.0L 100 hours can't run 10 seconds, and version 2.5 can't run for 9 seconds, which is really not enough.

Some data parties may say, "Torque determines acceleration and power determines speed". Magotan 1.4T broke through the 100-speed, because the torque was 40Nm larger than Camry 2.0, and it lost in the final stage of the contest with the extremely fast Magotan. I can also fully refute this point: first of all, once again, the torque of Camry 2.5 is no worse than that of 1.4T Magotan, and the power is nearly 60 horsepower more. Isn't it still beating magotan? Secondly, let's compare the speeds: magotan 1.4T 2 10km/h, Camry 2.5 2 10km/h, Camry 2.0 205 km/h, so where do you think Camry's extra motivation went?

The problem of Toyota's high horsepower is also reflected in the 2.0T engine. Or home test, the same 220 horsepower, 350Nm 2.0T, Highlander only ran 8.85 seconds at the fastest, and the bigger Touran was 8.3 seconds at the slowest (8.03 seconds at the fastest). At least in the performance dimension, Toyota's engine is not as good as Volkswagen's, and Toyota is not here. I think it's almost enough. 6-8 generations of Camry, old Lei Ling and old Highlander, all of which I have been driving for a long time. Their driving experience is generally as light as water, but it is really difficult to control, which is very suitable for consumers who have no driving feeling and want to worry.

In addition, the old concept that "torque determines acceleration and power determines speed" is also inaccurate. In fact, it is power that determines acceleration and speed. Only the speed spell is the maximum power, while the 0- 100 accelerated time spell is the average power. Because the torque and speed (ignoring the constant) is the power, large torque, insufficient speed or high speed and small torque can not play the ultimate performance of an engine.

For the engine, torque, speed and power are equivalent to the stride, pace frequency and speed of human running. Can you stride and run? Not necessarily, it depends on your pace frequency. If the product of the two is large, it can really run very fast.

Of course, the above are the dynamic performance of floor oil. If you use the throttle depth of daily driving, Camry 2.5 will drive more calmly than Magotan 1.4T as long as the throttle does not exceed 2/3, and the latter will often feel overwhelmed. This is mainly caused by poor linearity of Magotan throttle, lazy shifting style of gearbox and slow dynamic response of engine.

In addition to the Japanese navy in China, it is recognized that German cars are better cars, including Japanese.

Because German cars are better positioned, German cars can be made at a higher cost, and the cars made are of course better.

For the parts that the car can see, the precision of sheet metal is higher than that of German cars, so German cars can use laser welding technology. From the outside, the gaps in the sheet metal of German cars are smaller, which means higher body rigidity is needed, otherwise, when the body is twisted, there will be interference between the plates. In addition, the gap is small and a little uneven, which can be seen by visual inspection. Therefore, the large gap actually covers up the lack of rigidity of the car body and the uneven gap, which are guaranteed by materials and technology.

It is said that the driving quality of German cars is better. In fact, this is also a cost pile. Japanese cars pay more attention to daily visible parts, such as chassis, which is much simpler than German cars. The Japanese must know that the Germans do that, and the quality is better, but they will definitely pay more.

As far as the honesty of some materials is concerned, Japanese cars are not only inferior to German cars, but also inferior to other European cars and American cars. You can't say this is unreasonable, because most consumers don't know the difference.

Coupled with the incomparably powerful Japanese navy, Lexus, whose sheet metal work is in a mess, can be blown as a representative of craftsman spirit, but how many people can know the gap in Japanese machinery manufacturing technology?

After reading several big coffee answers, they are all perfect; In fact, this is still a game of strength and torque. The power of the 2.0L Camry is indeed slightly higher, but it only refers to the limit power, and the power at a certain moment is not necessarily higher (instantaneous power)! The machine limit power of Volkswagen 1.4T is indeed slightly lower, but with the characteristics of turbocharging and low torque, it can generate instantaneous power greater than 2.0L self-priming at a certain moment!

First of all, the parameter that determines the acceleration can only be power, but please don't take the maximum power (that is, the data on the parameter table) as an example. What really determines the acceleration at a certain moment is the instantaneous power; But when it comes to instantaneous power, how can we not talk about instantaneous torque and speed? I have always opposed the separation of power and torque, in fact, power is torque multiplied by speed; It is true that the instantaneous power is high and the acceleration is strong, but at the same speed, the machine with high instantaneous torque can release more instantaneous power, so it is not too outrageous to say that the torque determines the acceleration. After all, high torque * speed = high power, and high power has strong acceleration. Now can you clarify the relationship between torque and power?

Power = torque speed (ratio constant not written)

In fact, through this standard formula, we can easily understand many problems. Of course, the maximum self-priming power of Camry 2.0L is higher than 1.4T, but the engine can't keep the maximum power at any time. The key to determine the instantaneous power is the speed and torque, which are either large, large or both. Only in this way can more instantaneous power be released and greater acceleration be obtained. This should be judged by combining our daily driving hours and common speed intervals; Daily driving is not a racing car, so it is impossible to run on the red line for a long time, so the maximum power is often just a signboard, which looks plump but invisible!

To give a simple example (the data is not carefully verified, just a general direction, please don't take it seriously), we all know that the torque of turbocharged engines is greater at low speeds, so we will set a speed, that is, 2000, which is commonly used in daily driving, to the standard; Assuming that the floor oil, 2000 rpm, Volkswagen 1.4T can release the peak torque of 250Nm, while the torque of Toyota 2.0L at 2000 rpm is definitely less than 250Nm (in fact, the maximum torque is only 2 10Nm), then we can get two equations. . .

1.4T power =250 nm 2000 rpm.

2.0 litres of power = less than 2 10 nm, 2000rpm.

So when the floor oil is at 2000 rpm, whose output power is greater? Of course, it is Volkswagen's 1.4T engine, which is the core meaning of low rotation and high torsion. Without the support of speed, it still releases instantaneous high power, and this instantaneous high power determines the acceleration! Therefore, it is not rigorous to say that torque determines acceleration, nor is it rigorous to say that maximum power determines acceleration, but that acceleration is determined by the product of torque and speed, which is the perfect answer. But then again, what is the result of torque and speed? Of course, it is still power, but it is not the maximum power, but the instantaneous power in a certain state! The maximum power of Camry 2.0L is large, but the instantaneous power released in the range of 2000 rpm is lower than 1.4T, and the acceleration feeling is not as good as 1.4T!

In fact, this is the helpless problem of natural inhalation. If my car's 3.7L speed is limited to less than 2500 rpm, I don't feel as strong as 2.0T, because the low-speed torque can't come up, so the low-speed power can't come out, and the acceleration performance is not ideal. Natural inhalation is very dependent on speed. If 2.0L and 1.4T both run on the red line, then theoretically, therefore, the biggest contribution of turbocharging is to make the power release more reasonable. For self-priming, you can't do it without speed and motivation. For turbocharged engines, even if the speed is not high, high power can still be released with high torque at low speed. Of course, we should also consider matching the dual clutch with better performance!

Camry's 2.0L is naturally aspirated, so the speed of self-priming engine can't be compared with that of turbocharged engine, even if it is a small displacement turbocharged engine.

Toyota M20C has a maximum horsepower 178Ps/6600rpm and a maximum torque of 210n m/4400-5200rpm.

Volkswagen EA2 1 1, maximum horsepower 150Ps/5000rpm,

The maximum torque is 250 n m/1750-3000 rpm.

As we know, the power of a car has two parameters: maximum horsepower and maximum torque. This is where car manufacturers are sloppy. Naturally aspirated engines with maximum horsepower and torque come later than turbocharging.

Torque is a parameter representing the acceleration performance of an automobile. For example, at 2000 rpm, the torque of Volkswagen EA2 1 1 is already 250 Nm, while the torque of Toyota M20C may be less than 130 Nm, and 2000 rpm is the general engine speed when we are driving normally.

Nowadays, cars like to have a performance of zero acceleration to show whether the engine power is good or not. Toyota's self-priming engine can be said to have no advantage in this respect. Self-priming engine has strong driving sense and linear speed increase. Engines have been contributing to fuel cut-off protection. You will feel that the car accelerates slowly at 1000-2000 rpm and speeds up a little at 2000-4000 rpm. The maximum torque does not come into play until the speed reaches 4000 rpm. At this time, a golf with Volkswagen EA211.4t engine has already thrown it away. . .

But don't worry, when the tail speed of golf exceeds 150, you will find that it starts to slow down, and Camry can continue to accelerate, but once it reaches this level, it will basically be a speeding ticket.

So if you drive a Toyota, you should believe in Buddhism and don't always think about breaking up with others. Heaven has reincarnation. When the public shakes their heads and sighs at the high price of No.95 gasoline, remember to shout: 92, fill it up!

Power is the product of torque and speed. The maximum power (13 1KW) and maximum torque (210n m) of Camry 2.0 engine are 6600 and 4400 ~ 5200 respectively. The maximum power (1 10KW) and maximum torque (250n·m) of Volkswagen 1.4T engine are 5000~6000 and 1750~3000 respectively. From this comparison, it can be seen that the power of Volkswagen 1.4T is actually high in the engine speed range commonly used by ordinary people to drive, and the power of Camry 2.0 engine is reflected in the high engine speed range, so it is difficult for ordinary people to use the high engine speed range when driving. So you will think that Camry's 2.0 engine is not as powerful as Volkswagen's 1.4T engine.

When driving daily, the Camry of 2.0 accelerates very fast or has the need to drive at high horsepower in an instant, which is really a bit overwhelming. Compared with Volkswagen's 1.4T turbocharged model, there are indeed some gaps in driving experience, mainly for the following reasons:

The self-priming engine can only output high power in the high speed range.

Toyota Camry adopts Toyota M20C 2.0L naturally aspirated engine. According to the book data, the maximum power 13 1KW, the maximum torque 2 10Nm, the maximum power rotation speed 6600 rpm and the maximum torque range 4400-5200 rpm. That is to say, the output power of naturally aspirated engine increases linearly, and high speed brings high speed. 0- 100 The measured acceleration is 10.35 second.

Take Volkswagen Magotan as an example, the low-equipped EA211.4t turbocharged engine has the maximum power 1 10KW, the maximum power is 250 Nm, the maximum power speed is 5500-6000, and the maximum torque range is/KLOC-0.

According to the actual acceleration results, Camry's 2.0L naturally aspirated engine has higher maximum power output, but its acceleration ability is not as good as that of 1.4T turbocharged engine. The reason is very simple, that is, when the car is speeding up, the sooner the maximum torque comes, the greater it is, and the better it is for speeding up. 1.4T turbocharged engine is not as powerful as 2.0L naturally aspirated engine, but it is not as powerful as 2.0L turbocharged engine. Moreover, Camry's maximum power is often obtained at a higher speed, while turbocharging is at its maximum torque only at 65,438+0,750 rpm. That is to say, in terms of effective torque, Volkswagen's 1.4T turbocharging is obviously earlier and larger. Relatively speaking, Camry needs to be pulled to a higher speed to output more power, which gives people the feeling of insufficient power.

When the small displacement turbocharged engine is supercharged, the power rises faster than that of the naturally aspirated engine.

In daily driving, once the turbocharged engine is supercharged, the power will increase faster than that of the naturally aspirated engine. This is because the turbo 1.4T turbocharger is in a positive pressure state, the intake pressure is large enough, and the intake air volume has far exceeded that of the 2.0L naturally aspirated engine. Therefore, its output power at low speed is much higher than that of naturally aspirated engine at the same speed, even though the maximum power ratio of 2.0L naturally aspirated engine is 65438+.

The CVT gearbox used in Camry 2.0 has poor sense of rapid acceleration.

Toyota Camry 2.0 adopts CVT gearbox, and its middle re-acceleration ability is relatively poor. When accelerating rapidly, the TCU of the gearbox needs to limit the engine speed and wait for the CVT bevel gear to change the transmission ratio before it can output power normally. In this process, the speed change of the car can only rely on the natural increase of the engine speed, and the engine speed rises rapidly, so it gives people a feeling of insufficient power.

Generally speaking, the power of an automobile refers to the power that the engine can provide to drive the vehicle forward, so theoretically, the greater the engine power, the better its power. But in fact, the maximum power of many turbines is not self-priming, but it feels that the power of turbines is better when driving, and the acceleration of turbines is often better. Does this mean that power cannot reflect power? Actually, it's not like this.

Reasons for Good Dynamic Performance of Turbine

Power is an abstract noun, which can be described by an easily quantifiable parameter, that is, power. Regardless of vehicle weight, gearbox, resistance and other factors, it can be considered that the greater the output power of the engine, the better the power sense. And power = torque speed 9550, the difference of engine speed in our daily driving is not particularly large, so the output power mainly depends on torque at this time. The advantage of the turbine is that it can output more torque in a lower speed range, so it can output more power in the speed range commonly used in daily driving.

The maximum torque output point of self-priming engine is basically after 3500 rpm, and the maximum power point is even higher, which is not used by most people in daily driving. In contrast, the power performance of self-priming engine in general range is not as good as that of turbine.

How to show the high power advantage of self-priming engine?

This is a very sad answer: if you just drive everyday, you basically don't need the high-power advantage of self-priming. The easiest way to realize its high power advantage is to accelerate it. At this point, it is estimated that everyone will laugh: the power is high, but the acceleration of 100 kilometers is not as good as the self-priming car of the turbine. Yes, but why limit yourself to 0- 100? The acceleration of 0- 100 mainly depends on the output power of the lower speed range, because now many cars can break through the second gear, and the first gear begins to pull to the red line, and the speed immediately drops to the lower speed range after the second gear is accelerated. The output power of the turbine car is greater in this range, while the output of the self-priming car is in the high speed range, which is naturally not cheaper than the self-priming car.

But let's change the rules and have a 400-meter acceleration race. At this time, I'm afraid the plot will be reversed, because there is enough distance for the engine to accelerate as much as possible. At this time, when the speed reaches 100, the turbine may lead temporarily, but the race is not over yet. You have to run 400 meters, so the engine will continue to accelerate. As the gear is higher and higher, the speed is higher and higher after each shift. This range is very uncomfortable for the turbine, because the supercharger does not have much squeezing space, and the self-priming engine is a large output range, so the self-priming car begins to overtake gradually. This is why many performance cars will choose 400 meters acceleration instead of 0- 100, and the more powerful engines in the 400 meters acceleration will basically overtake in the second half.

Therefore, to sum up, the turbine with lower power has a better power experience because its larger output is in a lower speed range during daily driving. Although the power of similar self-priming engine is slightly higher, its large output is in the high speed range, so it is difficult to use in daily driving, so the power sense is not as good as that of turbine. However, if the self-priming speed is pulled to the high output range with low gear, it is definitely better than the turbine experience. The most important point is that at high speed, re-acceleration is better than turbine. This is the difference between turbine self-priming and premature over-overdraft.

Toyota is a famous dummy king. Toyota engine is characterized by outdated technology and conservative training, so it has gained a solid and durable reputation. Suitable for short-distance shopping in cities with low performance requirements. At the same time, it is for the sake of selling points, so it has been punished many times in the American market since the 1980s. If Toyota really pays attention to engine performance and taps its output potential like the European and American departments, the failure rate is not low at all, and there is no advantage in fuel consumption, such as the recent burning of engine oil and the increase in engine emulsification. That is to say, Toyota has just begun to cross the hurdle that others have already crossed, and has fallen behind for nearly 20 years. Turbocharging and gearbox technology are the same. There is no way to overtake in corners, but new emission standards have been implemented. As a last resort, we can only find the low-performance short-lived CVT that has long been eliminated by the world and rush to the third cylinder. Predictably, Toyota's prognosis is very bad. As for Volkswagen 6AT, which Toyota powder has been blowing, Aisin gearbox is used to prove how awesome Toyota technology is. The truth is that the intellectual property rights and patented technology of Tiptronic 6AT are open to the public, and Aisin is only OEM. It is a truth that the mobile phone chips of Apple, Qualcomm, Hisilicon and MediaTek are all produced by TSMC. Whoever pays will do it. Even so, due to the consideration of emission requirements, the public is eliminating the popular 6AT and turning to DCT. Toyota 6AT has just been laid off from the mid-level car for a few years, and the double clutch is gone, so CVT can only be used to save the scene temporarily. The reason why Toyota is so embarrassed is that it started late compared with European and American cars, lacked technical accumulation and had a gap in production and processing technology. At the same time, it does not pay attention to the research and development, promotion and application of new technologies and lacks core competitiveness. It ponders how to expand market share by reducing costs and increasing efficiency, which can't keep up with consumption upgrading and policy change orientation. This is also a common means for backward countries to catch up with advanced countries, such as Korean cars. In just 20 years, there is a tendency to surpass Japan, just as Japan surpassed the American department at the beginning, because the threshold for meeting these basic needs is too low, and the horizon is four wheels and one sofa. Can we expect it to innovate and guide the development trend of automobiles?

For a car, the torque directly determines the strength. For example, in the initial stage, the greater the torque, the faster the start. The acceleration time of 0- 100 km depends entirely on the torque, so the torque is one of the important parameters to evaluate the performance of a car. Horsepower is just a manifestation of power. The higher the power, the faster the acceleration in the middle and rear section. Knowing the meaning of these nouns, we can easily understand the difference between Camry and Volkswagen. The maximum torque of Camry 2.0L is 2 10 Nm, while that of Volkswagen 1.4T is 250 Nm. Who is more explosive must be the public.

For example, driving in a congested urban area, we will start frequently. At this time, the high torque output advantage of Volkswagen 1.4T is reflected. On the other hand, Camry will be a little lazy and smooth, and the most direct feeling for our drivers is boredom. But once you run, the acceleration in the middle and late stages is still better than Camry. In fact, the focus of the two engines is different. Camry 2.0L focuses on stability and ride comfort, and toughness is not his orientation. Volkswagen 1.4T is a small displacement engine, and its large torque output can beat many 2.0L displacement vehicles, which is of great significance in daily driving, especially at low speed most of the time.

In addition, the maximum torque speed of Volkswagen 1.4T is much lower than that of Camry 2.0, which means that we can easily trigger large torque output to make up for the problem of insufficient displacement. For example, Volkswagen Passat, Magotan and other medium and large cars are all 1.4T engines. Literally, the displacement is too small. Will there be a small horse-drawn cart Actually, it is not. I hope my answer is helpful to you.
