What Are the Three Major Factors Affecting Car Fuel Consumption?

[Bentley]

There are three major factors affecting fuel consumption: 1. Rough roads increase fuel consumption: Poor road conditions or uneven surfaces force the vehicle to drive in low gear for extended periods, inevitably increasing fuel usage; 2. Using the trunk as storage increases fuel consumption: Loading the trunk with unnecessary items increases the car's weight. Many overlook that vehicle weight is directly proportional to fuel consumption. Reducing weight by 10% can lower fuel consumption by several percentage points; 3. Incorrect driving habits can double or triple fuel consumption: Poor driving practices have the most significant impact on fuel efficiency. During driving, especially in heavy traffic, at red lights, or when changing lanes, sudden acceleration and hard braking are the most common issues.
