Under 49 CFR Part 538, Automotive Fuel Economy Manufacturing Incentives for Alternative Fuel Vehicles

To provide an incentive for the production of vehicles that can operate on certain alternative fuels as well as on regular petroleum fuels, Congress established a special procedure for calculating the fuel economy of those vehicles for determining compliance with the Corporate Average Fuel Economy standards.

Rear Visibility NCAP Request for Comment

This document requests public comment on the agency’s planned update to the U.S. New Car Assessment Program (NCAP). This update would enhance the program’s ability to recommend to motor vehicle consumers various vehicle models that contain rearview video systems that would substantially enhance the driver’s ability to avoid backover crashes.

Occupant Crash Protection

This document adopts NHTSA’s proposal to require all designated seating positions in rear seats, other than side-facing seats, be equipped with Type 2 integral lap/shoulder safety belts. Side-facing seats may be equipped with either a Type 1 lap belt or a Type 2 belt. This final rule responds to a Congressional mandate that the agency begin to phase-in requirements for lap/shoulder belts for all rear seating positions, wherever practicable, not later than September 1, 2005.

Draft Environmental Assessment

The draft environmental assessment evaluates the potential environmental impacts associated with NHTSA’s proposed action to set Corporate Average Fuel Economy Standards for model year 2008-2011 light trucks. This document describes the environment and resources that might be affected by the proposed light truck CAFE standards for model years 2008-2011, and assesses estimated impacts of alternative actions.

NHTSA: 49 CFR Parts 531, 533, and 537; EPA: 40 CFR Parts 86 and 600 Establish Light-Duty Vehicle Greenhouse Gas Emission Standards and CAFE Standards

EPA and NHTSA are issuing this joint proposal to establish a National Program consisting of new standards for light-duty vehicles that will reduce greenhouse gas emissions and improve fuel economy. EPA is proposing greenhouse gas emissions standards under the Clean Air Act, and NHTSA is proposing Corporate Average Fuel Economy standards under the Energy Policy and Conservation Act, as amended. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016, and represent a harmonized and consistent National Program. Under the National Program, automobile manufacturers would be able to build a single light-duty national fleet that satisfies all requirements under both programs while ensuring that consumers still have a full range of vehicle choices.
