Why does the BMW 325 have high fuel consumption?

[MacIsaac]

Factors affecting fuel consumption include: 1. Engine displacement: Different vehicles inherently have different fuel consumption levels. Generally, SUVs consume more fuel than regular sedans. When purchasing a car, you can choose models with relatively lower fuel consumption. Fuel consumption is related to engine displacement. A 1.0L displacement car typically consumes around 5 liters per 100 kilometers; 1.5-1.6L displacement cars consume approximately 7 liters per 100 kilometers. These are just reference values, and actual consumption depends on specific vehicle conditions. 2. Road conditions: Stop-and-go traffic with frequent acceleration and braking increases fuel consumption. Generally, smooth roads are more fuel-efficient than bumpy ones, straight roads save fuel compared to winding ones, and clear roads are better than congested ones. 3. Weather: In hot summers, air conditioning cooling consumes extra fuel. In cold winters, low temperatures prevent gasoline from reaching optimal combustion temperature, resulting in incomplete combustion and additional fuel waste. 4. Driver habits: Vehicle load and improper driving techniques also affect fuel efficiency.
