How do Japanese cars achieve low fuel consumption? Are Japanese cars light in weight and therefore low in fuel consumption?

Many car enthusiasts know that Japanese cars are fuel-efficient. Fuel economy is an issue that car enthusiasts need to consider when buying and using cars. If you want to save fuel, it is recommended to buy Japanese cars. But why are Japanese cars fuel-efficient? What is the basis for Japanese cars to be fuel-efficient? Let’s read the article below to find out!

How do Japanese cars save fuel?

The idea that Japanese cars are fuel-efficient came from the United States. In fact, before the first oil crisis, the mainstream of the American car market was muscle cars (driven by rich people) and pony cars (working class cars). Both of these cars were powered by V8 engines. At that time, gasoline in the United States was very cheap (cheaper than Coke), so consumers were obsessed with large-displacement naturally aspirated cars, and people from all walks of life could afford them. Later, the oil crisis broke out, and the United States, which was extremely dependent on oil resources for survival, fell into a dilemma. Faced with soaring oil prices, V8 car owners were helpless because before that, the United States had never considered fuel economy when making cars!

Are Japanese cars lighter and less fuel-efficient?

The most advanced technology now is the development of car bodies towards lightweight. For example, the most advanced car body material now is carbon fiber, followed by aluminum alloy. Various high-end car models have begun to take the lightweight route, but are they fuel-efficient?

That's not necessarily the case. The positioning and direction are different, and the purpose of lightweighting is naturally different. However, for our family cars, being lighter can indeed save fuel consumption.

If you don't believe it, you can consider driving your car with four 200-pound friends for a week every day, and then driving it empty for another week to see which time you save more fuel.

The reduction in car body weight will directly affect fuel consumption. Some friends may talk about safety issues. In fact, the reduction in car body weight has little to do with safety. The car body structure is the most important factor in determining safety.

What are the characteristics of Japanese car gearboxes?

A gearbox with high transmission efficiency can play a good role in reducing fuel consumption. High transmission efficiency plus excellent matching and tuning can save 5%-10% of fuel consumption. Japanese cars mostly use CVT gearboxes, and CVT has good fuel economy, which reduces the average fuel consumption to a certain extent.

In terms of CVT technology, Japanese companies are the most representative. Many Japanese companies focus on CVT, and use CVT as their own advantageous technology to compete with German and American companies. Therefore, Japanese companies have also played their inherent advantages, and have continuously updated and developed them. CVT has been developing towards starting gears. A high thermal efficiency engine + a fuel-efficient gearbox will definitely significantly improve its fuel consumption.

In fact, fuel consumption is only a small part, and maintenance is the big part. For the same 200,000-level car, the Camry is serviced every 10,000 kilometers, and the price of replacing the oil and filter is generally around 500 yuan.

For Magotan, the maintenance period is 7500, but it costs about 1000 for each maintenance. Of course, maintenance at a repair shop is another matter.
