Toyota is running a global fleet of 500 Prius plug-in demonstration vehicles.

SAE International has approved a revised standard for measuring emissions and fuel economy from hybrid and plug-in hybrid vehicles. "J1711 – Recommended Practice for Measuring the Exhaust Emissions and Fuel Economy of Hybrid Electric Vehicles, including Plug-in Hybrid” spells out test procedures designed to allow engineers to more consistently and accurately evaluate these types of vehicles under a wider range of evaluation cycles. The procedures will result in consistent information to the consumer, according to Michael Duoba, an automotive engineer with the U.S. Department of Energy's Argonne National Laboratory who serves as Chair of the SAE International Hybrid J1711 Task Force, which wrote the revised standard. “Until now, the fuel-economy claims for plug-in hybrids were not calculated according to similar procedures, making car-to-car comparisons virtually impossible," he explained. "What makes this procedure—and other SAE-developed recommended practices—significant is that EPA 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.” The EPA has yet to decide how to calculate fuel economy for plug-in hybrids.
