Why is Volkswagen’s engine not as powerful as Honda’s engine, but has higher torque than Honda’s?

First of all, Honda has been racing for decades. Many of its civilian technologies have evolved from racing, especially the engine. This is the DNA of the Honda brand, so its engine tuning is based on racing ideas. Come on, high power and low twist.

And from the perspective of engine technology, Honda has used the same set of power in China for a long time. Although the old set of power is still okay now, compared with the new generation of engines ( For example, Mazda's Chuangchi Blue Sky lags behind because of its low-torque characteristics. Honda's new Earth Dream engine data has been improved a lot, the torque has increased by more than 20% for the same displacement, and the power has also been further improved. Another reason is domestic fuel. Domestic fuel cannot meet foreign standards. When Honda engines entered the country, they made concessions on oil quality and weakened the engine performance. This also has a certain impact. The same type of Honda engine heads are sold abroad. The data is a little better.

The displacement of the engine is actually an input power, and the maximum power you mentioned is actually the output power. A large input power does not necessarily mean a large output power. We know that Volkswagen is a German car, and the car has a large weight, so it will lose part of its power. However, Honda is a Japanese car. On the one hand, the material of the body is different and the weight is relatively small. On the other hand, the Japanese have reduced the weight by removing the anti-collision steel plates on both sides of the body, so the output power is what you call the maximum power. Bigger than the public.

In addition to the body design, it also has a lot to do with its original power. The Fit and Jetta are also equipped with brand-new 1.5L engines. Let’s first compare the book data of the two cars. Among them, the Honda 1.5L engine has a maximum power of 96kw and a maximum horsepower of 131ps. Volkswagen’s new 1.5L engine has a maximum power of 81kw and a maximum horsepower of 110ps. Judging from the book data, Honda beats Volkswagen with an overwhelming advantage. In terms of actual driving experience, compared with the two manual transmission models, the Fit's acceleration time is 8.8 seconds, while the Jetta's acceleration time is 10.8 seconds. The difference in fuel consumption is negligible. With the same 1.5L displacement, why is there such a big difference? In fact, Honda still takes advantage of its advantages in the engine field and uses technology earlier than Volkswagen. For example, Earth Dream's in-cylinder direct injection technology took the lead in raising the banner of Japan. Volkswagen's EA211 currently still uses multi-point electronic injection technology.

In terms of fuel atomization and thermal efficiency, Honda has more advantages than Volkswagen's EA211. Of course, the compression ratio of this engine is also stronger than that of Volkswagen, and a higher compression ratio will greatly improve the fuel conversion rate. For the same displacement, the higher the compression ratio, the higher the engine efficiency. Of course, Honda's 1.5L Earth Dream is not perfect. In China, it has been criticized by consumers because of its inability to adapt to oil products, carbon deposits, shaking, and stalling problems. The Earth Dream made Honda a success, and also dragged the Honda engine down from the altar. In terms of reliability, Honda's 1.5L engine is even inferior to Volkswagen's EA211 to some extent. Some deep-rooted ideas should be changed long ago, such as the myth of Honda engines and the problem of Volkswagen engines burning oil. At this stage, everyone should change their thinking. In fact, the oil burning situation of Volkswagen's EA211 engine is negligible, especially the naturally aspirated engine. Honda is no longer the most reliable engine due to the carbon deposit problem of Earth Dream.
