What is one of the main purposes of fuel-efficient driving techniques?

  1. Reduce environmental impact

  2. Increase engine power

  3. Enhance speed

  4. Reduce maintenance costs

The correct answer is: Reduce environmental impact

One of the main purposes of fuel-efficient driving techniques is to reduce environmental impact. By driving in a way that maximizes fuel efficiency, drivers can lower their vehicle's carbon emissions and the overall pollutants released into the atmosphere. Techniques such as maintaining a steady speed, avoiding rapid acceleration and hard braking, and reducing idling time contribute to more efficient fuel use, which in turn lessens the vehicle's contribution to air pollution and climate change. This approach not only benefits the environment but also encourages a more sustainable transportation system, making it a significant objective in modern driving practices. While increasing engine power, enhancing speed, and reducing maintenance costs are considerations in vehicle performance and economics, they do not specifically align with the primary goal of minimizing the ecological footprint associated with vehicle operation.
