The Next Generation Fuels Act is being introduced in the U.S. Senate.
A House version of the bill was introduced last August, and Senate sponsor Chuck Grassley says both versions require automakers to optimize vehicles for 95-octane with E20 by model year 2026.
“And 98-octane with E30 by model year 2031. Higher octane fuels improve engine efficiency as well as performance, and by doing that you lower emissions.”
During a call with reporters Tuesday, the Iowa Republican says the legislation also requires low-carbon sources for the added octane.
