KICK said:no it aint. a manufacturer can go forward, but cant go backwards when it comes to certification.
the Manufactuers wish it were a loophole.
when you call it an 07, they treat the whole thing as an 07, not just the body.
when it comes to auto emission equipment, its dead serious stuff and piles of money get spent validating equipment to meet those EPA specs.
I work on city transit buses, we cant even repower an old bus without upgrading to the newer engine that is certified to cleaner emissions. cant put back in what we had, its gotta be cleaner.
some of the heavy duty manufacturers, like Cummins didn't have to comply as soon as others because they earned EPA credits in the past, but everybody has to pass the 07 tests for their particular application.
OK............
Take a look at this link and tell me what engines are available for the '07 3/4ton truck.. Then, tell me it meets '07 emission requirements..
I dont mean to be combative, I'm just correcting a false statement.. There are loopholes and credits.. I guess it could possibly be that credits are used to avoid the emission requirements(for a time), but the fact is it happens..
