Description
The EPA has released its long-awaited proposal to revise the 2027 heavy-duty diesel emissions rules, but does it mean diesel owners can finally delete their trucks?
In this episode, Tim Esterdahl breaks down what the proposal actually changes, including the plan to eliminate many DEF-related engine derates, reduce warranty requirements and delay some emissions durability standards. He also explains what didn't change, why DEF systems and emissions deletes remain a hot topic, and why many diesel enthusiasts may still be disappointed.
If you've been following the diesel delete debate, this episode separates the headlines from the facts and explains what the EPA's proposal could mean for current and future diesel truck owners.
