The redesigned 2014 Mini Cooper Hardtop is one of those rare cars that puts a grin on your face and keeps it there even after refueling. The Cooper's window sticker lists highway fuel economy ratings near or above 40 mpg, depending on model, but it turns out that's not the case. According to the EPA, the frugal, fun 2014 Cooper isn't as frugal as Mini originally reported, and the agency is dinging both the Cooper's turbocharged three-cylinder engine and high-performance turbocharged four-cylinder Cooper S after auditing the cars in its own facility.

What happened? "This adjustment was made as the result of retesting models following notification by the EPA that road load testing for one model had delivered different results. Engineers worked closely with the EPA to incorporate these findings into Mini's computer simulation testing," Mini said in a statement.
Combined ratings are down 1 mpg across the board for the Cooper and Cooper S Hardtop. See a complete list of before and after ratings below.
