Honda Accord Hybrid Electric Vehicle Accelerated Reliability Testing – April 2008
Two Honda Accord hybrid electric vehicles (HEVs) entered accelerated reliability testing during January 2005 in one fleet in Arizona. After reaching 160,000 miles each, the two Accord HEVs will have their traction batteries tested before they are retired.
Fact sheets and maintenance logs for these vehicles give detailed information such as miles driven, fuel economy, operations and maintenance requirements, operating costs, and life-cycle costs.
The two Accord HEVs have been driven a total of 321,000 miles and the cumulative average fuel economy for the Accord HEVs is 28.1 miles per gallon. Note that one Accord was driven 300 miles in January without a fueling event, so the mpg for January is artificially high in the graph.
