Extreme Heat and Freezing Cold Drain Efficiency from Hybrids and EVs, Study Finds.

How Temperature Affects Vehicle Fuel Economy

According to Novyny.live: New research from the American Automobile Association (AAA) reveals that both hybrid and all-electric vehicles experience significant drops in fuel efficiency when exposed to extreme temperatures. The study highlights how weather conditions directly impact the performance of these eco-friendly cars.

During hot weather, hybrid models see a 12% reduction in fuel efficiency at 35 °C. Meanwhile, electric vehicles under the same conditions lose 10.4% of their efficiency. These findings show that while high temperatures hurt both types, hybrids are more affected by the heat.

Winter Testing and Its Outcomes

Cold weather proved even more challenging. At -7 °C, hybrid fuel efficiency falls by 22.8%, while electric vehicles suffer a steeper 35.6% drop. This means freezing temperatures severely cut into an EV’s real-world range, reducing it by 39%. For instance, a Tesla Model Y’s range shrinks from 479 km to just 253 km in winter conditions.

The data makes clear that both hybrids and EVs have distinct weaknesses in extreme temperatures, which could influence consumer choices based on local climate. Buyers in colder regions, for example, may need to plan for greater range loss in winter.

Understanding these temperature effects is crucial for consumers, as efficiency differences can substantially impact fuel or electricity costs. As global climate patterns shift, this information becomes increasingly relevant for anyone considering a hybrid or electric vehicle purchase. The study underscores the need for shoppers to factor in their local weather when making a decision.
