Autotrader's Mark Strand told AutoblogGreen that even though the number of green model offerings went up in the last year, market share has flattened out. This is especially notable since last summer was, "the hottest period for vehicle sales since the last recession," Strand said. Despite the overall healthy auto industry, the share of green vehicle registrations actually, "started trending down when gas prices were still increasing and continued to decline with gas prices above or near the $3.50 gallon mark." You can dig into the Autotrader data in the charts above.
"All of this suggests to that green vehicles had reached something of plateau before gas prices plummeted," Strand said. "Even with the doubling of available models since 2012, market share trended sideways at best and actually began to slide. The buzz around the dramatic drop in gasoline prices might obscure the fact that green vehicles were already challenged to break into the mainstream even in a high gas price environment."
What we take away from this is that the appeal of high-mileage and plug-in vehicles cannot be measured by those numbers at gas stations. Instead, we know that EVs won't die because of low gas prices and a good deal increases EV sales.
