Cold start emissions and preheating: A minimal impact

Published on October 12, 2023

Just like how wearing a jacket in the morning might not make a huge difference in your day, a new study shows that preheating your car during winter has minimal impact on fuel consumption and emissions. The researchers examined the effects of preheating on vehicle fuel consumption and emissions, specifically focusing on cold start emissions. They found that even with preheating, the benefits for both fuel economy and emissions were minimal under cold winter conditions. So, while preheating might give you a warm and cozy feeling inside your car, it doesn’t seem to have a significant impact on the environment. This study adds to our understanding of how to reduce vehicle emissions and improve fuel efficiency during cold weather. To learn more about this fascinating research, check out the full article!
