Per the auto research group Edmunds, "45 percent of this year's hybrid and EV trade-ins have gone toward the purchase of another alternative fuel vehicle." Lower gas prices have played a key role in reducing owner loyalty rates for such cars. When gas prices peaked in October 2012, it would take 5 years to recover the added price for a hybrid Toyota Camry versus a standard Camry. At today's gas prices, it will take 10.5 years.
