Your car is equipped with an automatic start-stop system. What is the environmental protection benefit from using this vehicle system?

The automatic start-stop system is designed to enhance fuel efficiency and reduce emissions by shutting off the engine when the vehicle is stationary, such as at traffic lights. This directly contributes to lower fuel consumption, which is crucial for minimizing environmental impact. Additionally, it helps in reducing noise pollution, particularly in urban areas where traffic is often stopped.

While tyre wear can be a factor in overall vehicle efficiency, it is not significantly impacted by the start-stop system itself, which is why it is not included in the correct answer. Regulations in Germany emphasize reducing both fuel consumption and noise levels to improve air quality and promote sustainability in urban settings. Thus, selecting options that pertain to these key benefits is essential for understanding the system's full environmental advantages.
