What is the fuel tank capacity of the BMW 740?

BMW 740 fuel tank capacity is 78 liters, which is the officially announced data. The fuel grade for the BMW 740 is 95, with a fuel consumption of 7.5-7.9L per 100 kilometers. A full tank can cover a distance of 987-1040km. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safety level, and there is still some space from the safety level to the tank opening. This space is designed to ensure that the fuel in the tank can expand when the temperature rises without overflowing the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the calibrated tank capacity.
I remember the BMW 740 has a pretty sizable fuel tank, with official data showing 74 liters. Last time I filled up my friend's car with 95-octane gas, it cost nearly 600 yuan. But the tank capacity depends on the specific model year – what I checked was the G12 chassis version after the 2020 model year. For highway driving, estimating 8-9 liters per 100 km, it can cover over 800 km. In city driving, it might be just over 600 km since frequent traffic lights consume more fuel. The fuel filler is located on the right side near the B-pillar, and remember to use at least 95-octane fuel. Some older models have a 68-liter tank, so used car buyers should keep an eye out for that.
