Yep, that's right, race cars are in the EPA's sights now:

While you can kind of see where they are coming from, I mean, if you're going to be serious about air pollution then why not cover all cars?, the motorsport industry undoubtedly has a lot of money so you can bet they will be opposing this with everything they have.
Can we get comparison data to see for example how much more do F1 cars pollute vs say a street legal car of similar engine size?

I'd say it's more about the aftermarket industry.

Think about all those parts that are sold as "not for high way use, off road only".

Everyone knows they end up on street cars regardless and increase the vehicles emissions.

It closes a loop hole that allows those parts to be sold at all.

SEMA will be up in arms as it's members stand to lose millions.

The restriction on converting road cars will be fought by many different groups, it'll be interesting to see what happens.

The emphasis here has been on using racecars to promote renewable energy sources, the V8 super cars all run e85 now. It would make more sense to mandate emissions levels and fuel sources.

...

That's my take on it as well.

I can see them mandating testing and compliance on all after market products. Ostensibly making competition compliant but also affecting SEMA's members. Will drive bolt on performance underground, or rely on products bought on the grey market from countries without similar legislation.

No doubt the Australian regulators (and lobby groups) will look on with interest.
