Based on the standard calculation of 6 yuan per liter for 93-octane gasoline, 10 yuan per 100 kilometers would mean 100 yuan per 100 kilometers. Dividing by the unit price of 6 yuan, this equates to 16.6 units of fuel consumed per 100 kilometers, which generally translates to a fuel consumption of 16.7L/100km. Below are some methods to reduce fuel consumption in cars: Gentle Throttle Application at Startup: Flooring the accelerator (sudden acceleration) actually consumes quite a bit of fuel. During startup, drivers only need to lightly press the accelerator to control the fuel injection, achieving the startup purpose while also saving fuel. Shifting Gears Properly: Shifting gears should be timely—neither too early nor too late. Generally, you can listen to the engine sound and refer to the tachometer, ensuring the engine speed matches the vehicle speed. Excessive throttle or low engine speed can lead to higher fuel consumption.

Only 1 yuan for 100 kilometers? That depends on the fuel price. For example, with the current fuel price around 7 yuan per liter, 1 yuan can buy less than 0.2 liters of fuel, which works out to roughly 0.14 liters per 100 kilometers. Such fuel consumption is too exaggerated. Even the most fuel-efficient hybrid cars today consume at least 4 liters per 100 kilometers, and normal gasoline cars require at least five to six liters. In all my years of driving, the lowest I've ever achieved is just over 5 liters. Unless you're riding a bicycle, it's simply impossible. However, if fuel prices were to plummet to 1 yuan per liter someday, there might be a tiny possibility.

To calculate the fuel consumption corresponding to 1 yuan per 100 kilometers, the current fuel price must be considered. Currently, 92-octane gasoline in China costs about 7 to 8 yuan per liter. Based on this, 1 yuan's worth of fuel equates to approximately 0.12 to 0.15 liters per 100 kilometers. However, in reality, most household cars consume at least 6 liters per 100 kilometers. For example, my car consumes around 8 liters in urban driving, which translates to over 50 yuan per 100 kilometers. Therefore, such extreme fuel efficiency currently exists only in theoretical calculations. Perhaps future breakthroughs in new energy vehicle technology could achieve this, but it's not realistic at present.

The key to this issue lies in the fluctuation of oil prices. For example, when the oil price was 7.8 yuan per liter this year, 1 yuan of fuel cost per 100 kilometers means the fuel consumption was only about 0.13 liters; if it were during the low oil price period a few years ago at 5.5 yuan per liter, the fuel consumption figure would rise to about 0.18 liters. However, even this is far below the actual fuel consumption, as motorcycles typically consume around 2 liters. My family's 1.5L naturally aspirated engine car consumes at least 5.2 liters in the most fuel-efficient state. So no matter how you calculate it, this number seems like a fairy tale. It would be more practical to focus on actual fuel-saving techniques.

Seeing this calculation, I immediately did the math: at the current oil price of 7.5 yuan per liter, 1 yuan per 100 kilometers corresponds to a fuel consumption of only 0.13 liters, which is absurdly low. To put it in perspective, the lowest fuel consumption record for hybrid vehicles is 3.9 liters, equivalent to over 30 yuan per 100 kilometers. Under normal driving conditions, fuel consumption per 100 kilometers typically ranges from 5 to 10 liters, translating to fuel costs of around 40 to 50 yuan. Unless there's a revolutionary breakthrough in engine technology or gasoline prices plummet to a few cents per liter, such low fuel consumption will forever remain confined to mathematical formulas.

This question seems simple but actually hides complexities. Taking today's oil price as an example, gasoline at 7.3 yuan per liter means spending 1 yuan per 100 kilometers implies consuming only 0.14 liters of fuel. However, in reality, even the most fuel-efficient electronic fuel injection motorcycles consume 1.8 liters per 100 kilometers, and ordinary cars can't achieve such low consumption. I've checked automotive industry data, and the most fuel-efficient mass-produced hybrid models still consume just over 3 liters, and that's under specific test conditions. So, don't be misled by such figures when actually driving; focusing on the vehicle's real fuel consumption performance is what truly matters.
