Celebrate the engines you love, but check the actual model announcement. EPA’s greenhouse-gas rollback does not lift exhaust-noise laws.
What to know
On February 12, 2026, EPA finalized the rescission of its 2009 greenhouse-gas endangerment finding and associated federal highway-vehicle greenhouse-gas standards. EPA explicitly distinguishes this action from standards covering traditional air pollutants.
For enthusiasts, that opens a discussion about future gasoline-engine choices. It does not itself announce a new V8, V10, or V12, and it does not erase separate noise requirements. Florida, for example, still requires functioning exhaust equipment to prevent excessive or unusual noise and prohibits highway use of muffler cutouts or bypasses.
Our take: our ears have every reason to rejoice when a great engine gets another chapter. A rich V8 rumble or a soaring V12 can be part of the appeal without treating deregulation as a guarantee of new models. Watch confirmed product plans, rather than comeback rumors.
