According to EPA assistant administrator Gina McCarthy, the letter grades—from "A+" to "D"—will be assigned on a bell curve, with the median being a "B-." That means most cars will cluster around a "B-," while few will get an "A+" or "D."
Specifically, according to the joint notice of proposed rulemaking by the EPA and the National Highway Traffic Safety Administration (NHTSA), 697 of the 2012 model-year vehicles will get a "B-," while 14 will get an "A-." There will be a dozen vehicles that get the lowest mark, "D." (The EPA counts each drivetrain variation within a model separately.)
