As reported earlier, the Environmental Protection Agency is planning to put automakers through real-world testing of their MPG claims. However, the agency is asking this be done on the track instead of the highway.
Edmunds reports the plans are in the “consideration phase,” with the aim of bringing claims in line with what drivers experience on the road, according to an unnamed EPA spokeswoman:
EPA is considering requiring automakers to perform supplemental test-track audits of production vehicles to validate the values for aerodynamic drag and tire friction, which are important data inputs for our laboratory fuel economy testing. Augmenting EPA’s existing pre-production procedures with post-production audits of real-world factors will help further ensure that the data used in EPA labels accurately reflect the vehicles consumers find on dealer lots.
She goes on to clarify that the testing should occur on the track, and that the agency is “not considering creating public roadway test procedures” to replace the results currently gained in the lab.
