Hybrid & electric vehicles

Argonne studies used to develop new SAE testing procedures for hybrid vehiclesJune 1, 2011

Plug-In Hybrid vehicles (PHEVs) are undergoing intense development and will be mass-produced within the next year. Federal regulators are struggling to come up with a definition of auto efficiency for this next generation of technology. Miles per gallon isn’t sophisticated enough; the onset of PHEVs requires new metrics to effectively convey information to consumers. The new metrics are expected to change the way fuel economy estimates are calculated and displayed.
