The headline is slightly misleading. The range estimations are lowered for these two reasons instead (buried in the article): > First, are “comfort and functionality improvements” made by Tesla that require more energy, and second is the implementation of revised EPA testing requirements that result in a “higher consumption and a slight decrease in overall range.” Personally I think the second reason is the main one. EPA gave automakers way too much leeway to tune the tests and report an inflated figure. It's good that they are tightening the procedures. However, it's quite possible that without the exaggeration attempts there wouldn't be any changes to EPA testing requiments.
