I say downwards:
With bargain gasoline prices putting more money in the pockets of Americans, owners of hybrids and electric vehicles are defecting to sport utility vehicles and other conventional models powered only by gasoline, according to Edmunds.com, an auto research firm.
There are limits, it appears, to how far consumers will go to own a car that became a rolling statement of environmental concern. In 2012, with gas prices soaring, an owner could expect a hybrid to pay back its higher upfront costs in as little as five years. Now, that oft-calculated payback period can extend to 10 years or more.
“We’d all like to save the environment, but maybe not when it costs hundreds of dollars per year,” said Jessica Caldwell, director of industry analysis for Edmunds.com.
It is a bigger shift than I would have thought:
In all, 55 percent of hybrid and electric vehicle owners are defecting to a gasoline-only model at trade-in time — the lowest level of hybrid loyalty since Edmunds.com began tracking such transactions in 2011. More than one in five are switching to a conventional sport utility vehicle, nearly double the rate of three years ago.
That one-and-done syndrome coincides with tumbling sales of electric and hybrid vehicles. Through April, sales of electrified models slid to 2.7 percent of the market, down from 3.4 percent over the same period last year, Edmunds.com said. At the same time, sport utility vehicles grabbed 34.4 percent of sales, up from 31.6 percent.
