49 CFR Part 538

Automobile Fuel Economy Manufacturing Incentives for Alternative Fueled Vehicles

This final rule extends the incentive created by the Alternative Motor Fuels Act of 1988 (AMFA) to encourage the continued production of motor vehicles capable of operating on alternative fuels for four additional model years covering model years (MY) 2005 to MY 2008. Under the special procedures for calculating the fuel economy of those vehicles contained in AMFA, alternative and dual fueled vehicles are assigned a higher fuel economy value for CAFE purposes, which can result in manufacturers earning credits for their fleets. The final rule limits the maximum amount of credit that may be applied to any manufacturers' fleet to 0.9 mpg per fleet during MY 2005 - MY 2008.

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.
