AAA’s latest study shows extreme temperatures reduce efficiency, range, and increase operating costs for electric vehicles and hybrids.
Impact of hot temperatures (95°F): Hybrid vehicles experience a 12.0% decrease in fuel efficiency. EVs show a 10.4% reduction in efficiency and an 8.5% loss of driving range compared to moderate temperature (75°F).
Impact of cold temperatures (20°F): Hybrids lose 22.8% in fuel economy. EVs demonstrate a 35.6% drop in MPGe and a 39.0% decrease in calculated driving range.
