Who says Japanese cars save fuel?Why did my Accord get 10.6 liters of gas mileage?Are all false

Lift car fuel consumption, it is estimated that most of the owners of the “Japanese” thumbs up, everyone says “fuel-efficient Japanese economy”, it was also confused by all comments, so, in 2019, I had a Honda accord, 1.5 T + CVT powertrain wireless version, the other is not much said, give everyone a bright light of the vehicle fuel consumption,The fuel consumption reaches 10.6L per 100km. Does this car save fuel?Accord really does not save fuel compared to the same level of 2.0t +8AT version of sonata ten, people match is 2.0T engine, the maximum torque is 353Nm, the maximum power is 176.5KW, the vehicle certification fuel consumption of 6.8L/100km, the actual driving fuel consumption of less than 10 oil;Volkswagen Magotan 2.0T+7DSG version, high power 2.0T engine, maximum torque of 350Nm, maximum power of 220Ps, its 100km fuel consumption is about 9 more oil.A contrast with the other people’s car, only to find that my Accord is really not fuel-efficient!You may say that the fuel consumption of a car is closely related to the driving habits, road conditions and external environment of the car owner. There is no denying that, after all, I drive in urban conditions and sometimes encounter traffic jams. However, through searching relevant information, the economy and fuel economy of Japanese cars may have become a thing of the past.First of all, why are Japanese cars considered “fuel economy”?As we all know, although Japan is a big country in science and technology, it is a small country in resources. Japan is short of domestic oil, and all the gasoline burned by domestic cars depends on imports. Due to the shortage of energy, Japanese cars have to devote themselves to creating economical and fuel-efficient models.Japanese car fuel economy strategy is simple, reduce vehicle weight, while improving the thermal efficiency of the engine.Due to the reduction of vehicle weight, Japanese cars are “light” to drive, owners of Japanese cars are very accurate evaluation — “thin skin car light”, “poor safety”;To improve the thermal efficiency of engine, it is an effective measures to reduce fuel consumption, but the engine technology has been very mature, the thermal efficiency of engine is difficult to get significant optimization, for now the skill level of the engine, engine thermal efficiency and Korea cars, Volkswagen, general motors car is not big difference, in addition to Mazda compression ignition engine,The thermal efficiency reaches more than 50% of abnormal condition, but it has not been applied yet.As for the weight of cars, Volkswagen, GM and Korean cars have also started to reduce their vehicles, and the vehicle repair quality has also declined significantly. As a result, compared with other joint-venture cars, Japanese cars have no significant advantage in fuel economy.Other car companies also have a very good performance in terms of fuel consumption with the development of economy, the global environment worsening, in order to improve environmental quality, governments began to strengthen control in the automobile emissions, in terms of China’s auto market, the ministry pioneered the six emission regulations, the regulation is history’s most severe, in addition, the ministry also launched a corporate average fuel economy,Let all car enterprises as far as possible to develop fuel vehicles with low fuel consumption, at the same time to the new energy vehicle field.Under the inducement of this policy, the car enterprises of various countries also exert all efforts to reduce the fuel consumption of vehicles.German cars developed turbocharged engines and dual clutch transmissions to reduce fuel consumption, while Korean cars developed new powertrains to reduce fuel consumption as well as reduce the vehicle’s spare quality. Gm even introduced three-cylinder engines to reduce fuel consumption.Therefore, in today’s automobile era, the advantage of low fuel consumption of Japanese cars no longer exists, and everyone’s overall level is almost the same.To sum up, low fuel consumption is no longer the patent of Japanese cars, and the fuel consumption of other joint ventures is also very low.
