UPDATE 3/10/16: Members of the U.S. House of Representatives and the U.S. Senate have introduced a new bill (HR 4715 and S.2659) that will clarify the Clean Air Act to explain it has always been legal to modify a street vehicle into a race car.
What You Can Do: In order to help get the bill passed, you can write your Congressional Reps and Senators to Support the RPM Act at www.sema.org/rpmletter.
A new website has been created at www.sema.org/epa-news that provides the latest information regarding the EPA’s proposal to prohibit the conversion of vehicles into racecars.
The U.S. Environmental Protection Agency (EPA) has proposed a regulation to prohibit conversion of vehicles originally designed for on-road use into racecars. The regulation would also make the sale of certain products for use on such vehicles illegal. The proposed regulation was contained within a non-related proposed regulation entitled “Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles—Phase 2.”
The regulation would impact all vehicle types, including the sports cars, sedans and hatch-backs commonly converted strictly for use at the track. While the Clean Air Act prohibits certain modifications to motor vehicles, it is clear that vehicles built or modified for racing, and not used on the streets, are not the “motor vehicles” that Congress intended to regulate.
