Less than one in four hybrids most recently reviewed by Vincentric generated lower ownership costs than their gas-powered counterparts. That's down from 32 percent in 2014 and from 44 percent in 2012. The Audi Q5 Hybrid, Ford Fusion Hybrid, Lexus CT 200h, Lexus ES 300h, Lincoln MKZ Hybrid, Toyota Avalon Hybrid, and Toyota Prius C were the models Vincentric deemed to have lower operating costs than conventional comparable models.
The narrowing gap is a result of lower gas prices and better overall fuel economy, both of which are great for the general public but not so great for those trying to sell hybrids. US gas prices currently average $2.20 a gallon, down from $2.58 a gallon a year ago, according to AAA. Meanwhile, average new-vehicle fuel economy has been hovering at about 25.5 miles per gallon for the past two years, up from 24.6 mpg for model-year 2014 and from 23.5 mpg for model-year 2013, according to the University of Michigan Transportation Research Institute.
Such factors appear to be impacting hybrid sales in the US. While plug-in vehicle sales through July are up about seven percent from a year earlier, total sales of hybrids, diesels and plug-ins have fallen about 22 percent this year. Notably, sales of four Toyota Prius hybrid variants have collectively declined 26 percent this year.
