Bill > S944

This bill, the Next Generation Fuels Act of 2023, aims to promote the use of low-carbon, high-octane fuels, protect public health, and improve vehicle efficiency and performance. Key provisions include: - Requiring automakers to design vehicles starting in model year 2028 to use gasoline with a minimum 95 research octane number, and starting in 2033 to use gasoline with a minimum 98 research octane number. Automakers and fuel retailers must install devices to ensure compatibility. - Prohibiting the sale of gasoline marketed as 95 or 98 research octane unless it meets those minimum standards. Requiring certain fuel retailers to offer 95 and 98 research octane fuel. - Directing the EPA to issue regulations to implement these requirements within 1-2 years of enactment. - Amending the Petroleum Marketing Practices Act to require labeling on vehicles and at fuel pumps about the minimum octane requirements and ethanol content limits for different model years. - Establishing an E40-compatible retail fuel infrastructure requirement and a clean octane standard limiting aromatic content and requiring low-carbon octane additives. - Updating vehicle emission testing procedures and the fuel economy calculation methodology for dual-fuel vehicles. The overall goal is to enable increased engine compression ratios and vehicle efficiency through the widespread availability of higher-octane, lower-carbon fuels.
