Tesla Model S
According to the Consumer Federation Of America (CFA), carmakers in the U.S. are improving fuel economy numbers, with more and more models compliant with Corporate Average Fuel Economy (CAFE) and related emissions standards.
The range of fuel-efficient options has never been broader.
CFA notes that now 63% of all-new 2016 models are CAFE-compliant.
"In comparing the CAFE compliance of “all-new” models in 2015 and 2016, there was a significantly higher percentage of CAFE-compliant vehicles in 2016. In fact, 63 percent of the “all-new” 2016 vehicles were CAFE-compliant, compared to 41 percent of the “all-new” 2015 vehicles (see Figure 3)."
There are two manufacturers that are 100% compliant - Tesla Motors, which offers only zero-emission cars and Mazda, which by offering only passenger cars (no SUVs) was able to meet the requirements without a plug.
