Bill > HR2434

This bill, the Next Generation Fuels Act of 2023, aims to promote the use of low-carbon, high-octane fuels and protect public health by improving vehicle efficiency and performance. Key provisions include: - Requiring new vehicles starting in model year 2028 to be designed to use gasoline with a minimum 95 research octane number, and model year 2033 and later vehicles to use 98 research octane or higher. This will enable increased engine compression ratios for improved efficiency. - Requiring fuel retailers to offer 95 research octane fuel by 2027 and 98 research octane fuel by 2032, with penalties for non-compliance. - Setting standards for the maximum allowable aromatic content and requiring low-carbon sources of octane enhancement in high-octane fuels. - Updating fuel economy and emissions testing procedures for dual-fuel vehicles to better account for use of alternative fuels. - Preempting state and local laws that conflict with the fuel and vehicle requirements in the bill. - Providing liability limitations for manufacturers and retailers who comply with the new requirements. Overall, the bill aims to enable continued improvements in vehicle efficiency and reduce carbon emissions through the widespread availability of high-octane, low-carbon transportation fuels.
