这份年度报告（“趋势报告”）是美国新个人车辆尾气二氧化碳（CO 2）排放、燃油经济性和动力总成技术趋势的权威参考。它自1975年以来每年出版一次，涵盖所有乘用汽车、运动型多用途车、小型货车以及除最大的皮卡和货车外的所有车型。支持本报告的详细数据由美国环境保护署（EPA）直接从汽车制造商处获得，以支持EPA的温室气体（GHG）排放和美国运输部国家公路交通安全管理局（NHTSA）公司平均燃油经济性（CAFE）计划的实施。这些数据自1975年以来一直由美国环保署收集和维护，构成了同类数据库中最全面的数据库。从2011年开始，今年新的替代燃料汽车（AFV）数据被整合到整个数据库中。这些车辆包括电动汽车、插电式混合动力汽车和压缩天然气汽车。此外，美国环保署和美国司法部宣布与现代和起亚达成和解，以解决涉嫌违反《清洁空气法》的问题。因此，美国环保署更新了趋势报告中包含的一些二氧化碳排放和燃油经济性数据，现代和起亚已被添加回所有制造商特定的表格。
This annual report (the “Trends report”) is the authoritative reference for tailpipe carbon dioxide (CO₂) emissions, fuel economy, and powertrain technology trends for new personal vehicles in the United States. It has been published annually since 1975 and covers all passenger cars, sport utility vehicles, minivans, and all but the largest pickup trucks and vans. The detailed data supporting this report were obtained by the U.S. Environmental Protection Agency (EPA), directly from automobile manufacturers, to support implementation of EPA’s greenhouse gas (GHG) emissions and the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) Corporate Average Fuel Economy (CAFE) programs. These data have been collected and maintained by EPA since 1975, and comprise the most comprehensive database of its kind. New this year data from alternative fuel vehicles (AFVs) are integrated into the overall database, beginning with model year 2011 data. These vehicles include electric vehicles, plug in hybrids, and compressed natural gas vehicles. In addition, the EPA and U.S. Department of Justice announced a settlement with Hyundai and Kia to resolve alleged Clean Air Act violations. Accordingly, EPA has updated some CO₂ emissions and fuel economy data contained in the Trends report, and Hyundai and Kia have been added back into all manufacturer specific tables.
