Yuan 2017 offers 5 models with a fuel tank capacity of 50 liters. The vehicle is equipped with a 5-speed manual transmission or a 6-speed dry dual-clutch transmission, and features front-wheel drive. Among vehicles in the same class, the Baojun RS-3 2022 has a fuel tank capacity of 45 liters, the Soueast DX3 2022 also has a 45-liter tank, while the KAMIQ 2022 comes with a 52.8-liter fuel tank. During actual refueling, the amount of fuel may exceed the nominal capacity. This is because the fuel tank capacity specified by automakers is measured from the bottom of the tank to the safety level, leaving some space between the safety level and the tank opening. This space ensures that fuel expansion due to temperature increases does not cause overflow. If fuel is filled up to the tank opening during refueling, the actual amount may exceed the nominal capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with E (empty) and F (full). When the needle is close to E, it indicates low fuel, while nearing F means the tank is nearly full.

Well, I've been driving the Yuan Pro for a while now. It has a 45-liter fuel tank, and a full tank gets me about 800 kilometers because I drive gently, with fuel consumption around 5.5L/100km. In the city, I only need to refuel every two weeks—it’s both convenient and cost-effective. For long trips, a full tank lets me drive from Shanghai to Anhui without stopping for gas. Compared to other compact SUVs like the Haval H6, which has a 60L tank, the BYD Yuan’s tank is smaller but more fuel-efficient, making it better for daily commutes. I’ve also noticed the fuel tank design is quite safe, with minimal risk of leaks, though I recommend checking the fuel cap seal regularly to prevent contaminants from getting in.

As a tech enthusiast, I've researched that the Yuan has a fuel tank capacity of 45L, utilizing lightweight materials to reduce vehicle weight and improve fuel efficiency. With an average fuel consumption of 6L/100km, it can achieve a range of over 700km. Coupled with BYD's DM-i hybrid system, it becomes even more energy-efficient. Although the fuel tank is compact in size, its layout is well-designed, making it suitable for congested urban driving conditions and reducing evaporative emissions. For long-term use, it's important to avoid using lower-grade gasoline to prevent carbon buildup. Compared to other brands, like the Toyota RAV4 which has a 55L tank but higher fuel consumption, the Yuan offers a more balanced approach.

I value environmental protection, and the Yuan's 45-liter fuel tank is considered moderate. A full tank can run for 750 kilometers but produces carbon emissions, reminding me to choose the hybrid or electric version for a greener option. During daily driving, reducing sudden acceleration and idling lowers the fuel consumption to 5.8L, saving money and reducing emissions. Compared to other new energy vehicles, the pure electric version offers longer battery range, while the fuel version's tank capacity can be upgraded. However, it's advisable to fill up moderately, not exceeding 90%, to avoid resource waste. It's recommended to use the BYD APP to track fuel consumption, ensuring sustainable travel.

From a cost-saving perspective, a 45-liter fuel tank costs about 270 yuan to fill up (at current fuel prices) and can cover 800 kilometers, costing less than 0.4 yuan per kilometer. For office workers like me, refueling only twice a month is enough, saving money for several meals. Compared to large SUVs like the Boyue with a 60L fuel tank, which incurs higher fuel costs, the BYD Yuan stands out for its affordability. It's important to avoid misjudgment due to fuel gauge malfunctions by having technicians check the fuel pump and wiring during maintenance. Using cruise control to maintain a steady speed while driving also helps save fuel.

During long-distance travel, the 45-liter fuel tank of the Yuan gives me peace of mind. A full tank provides a range of 700 kilometers, covering most highways and reducing the need for frequent stops. I plan my route to refuel every 600 kilometers, while also checking the tires and coolant to ensure safety. Compared to other models, the Honda CR-V has a 57-liter fuel tank but higher fuel consumption, making the BYD Yuan more balanced. It is recommended to use high-quality fuel to protect the engine. Carry basic tools such as an oil pump emergency kit in case of any issues with the fuel system.
