Key Takeaways
1. The government is considering eliminating the start-stop system due to mixed feelings from drivers.
2. The head of the EPA criticized the system as a way for manufacturers to enhance their eco-friendly image, stating that “everyone hates it.”
3. Start-stop technology can improve fuel efficiency by 4% to 26%, depending on driving conditions.
4. The EPA reports average fuel savings of 4% to 5%, while some tests showed up to 26% savings in specific scenarios.
5. Concerns about excessive wear on vehicle components from the start-stop system are often exaggerated, as it is designed for frequent restarts.
Drivers who feel mixed about the start-stop system, used by car makers to boost their eco-friendly image, will be pleased to learn that the government is considering getting rid of it entirely.
The head of the EPA recently stated that the start-stop technology exists mainly for manufacturers to earn a “climate participation trophy,” yet “everyone hates it.” This system is meant to turn off the engine during long periods of idling and then activate it again when the driver accelerates.
Fuel Efficiency Insights
According to various testing bodies, a start-stop system can reduce a vehicle’s fuel use by anywhere from 4% to 26%, depending on driving conditions and habits. The EPA claims an average fuel savings of 4% to 5%, while tests conducted by SAE with four different vehicles showed a reduction of up to 26% in fuel consumption when driven in the New York City Cycle (NYCC) scenario.
Valid Concerns
While some criticisms of the start-stop system can be argued against, many are entirely reasonable. Currently, approximately 65% of new vehicles come equipped with this technology right from the factory. Concerns about it causing excessive wear on the starter, battery, or engine are often exaggerated, as the system is specifically designed for frequent restarts.
