Warrendale, Pennsylvania – Vehicle standards association SAE International has introduced a new, revised standard to accurately measure the exhaust emissions and fuel economy of hybrid and plug-in hybrid electric vehicles.

The revised standard provides test procedures that recognize the expanded design diversity of such vehicles, and more consistently rates them under a wider range of evaluation cycles, realistically evaluating their potential fuel savings.

“Until now, the fuel economy claims for plug-in hybrids were not calculated according to similar procedures, making car-to-car comparisons virtually impossible,” said Michael Duoba, chair of the SAE International hybrid task force. “What makes this procedure, and other SAE-developed recommended practices significant, is that EPA (U.S. Environmental Protection Agency) typically considers them as the basis for the automotive regulations it promulgates. Ultimately, the consumer benefits with valuable vehicle information that can help guide a purchase decision.”
