Seems like a crazy question, but I was wondering if anyone had worked out the CO2 emissions on a small block / big block E-body?

As the world is going green I was interested to find out how our cars compare to modern cars with EGR valves and catalytic converters.

I read the Hellcat does 456g/KM.  How much worst are our old cars?

You're gonna have to have your own car tested.   A bone stock restored to blueprint spec engine will be different than a worn out stock-ish engine will be different than a radical striker with ported beads huge duration cam with lots of lope/overlap. 

In other words... too many variables

"CO2 emissions directly correlate with the amount of fuel burned, which means a small car like a Mini or VW Beetle produces no more greenhouse gases than the average new car. Other pollutants are a different story.

There have been drastic improvements in emissions equipment since the first standards came into practice in 1973. For example, a new car can't produce more than 0.2 grams of NOx per mile. 1989 model cars, the most recent vehicles considered "classic," can produce a full gram per mile, while a car built in the mid-70s can produce three grams. Other pollutants like unburned hydrocarbons have seen major drops while formaldehyde wasn't addressed until 1994."

CO2 emissions and fuel consumption go hand in hand - it's actually a lot more straightforward than NOx, HC, and CO emissions where there are definite sweet spots that may or may not coincide with peak efficiency or power output.  The more fuel you burn, the more CO2 you generate.

Greenhouse Gas emissions reductions have been hitting the HD truck world since 2017, and the way to achieve them really revolves around increasing fuel efficiency.  Note:  the engine is only one portion of that equation -  the rolling resistance, final drive ratios ,transmission, weight, various friction losses, aerodynamics, and a whole slew of chassis related items play into how much CO2 a vehicle will produce.

So I guess no one has had their car measured then.

And so many variables as mentioned, everyone's car will be different.

As said CO2 doesn`t change by car, it is directly to how much gas is burned. Other emissions will vary but yes, your car would need to be tested. New Hampshire only tests cars and light duty trucks with OBDII so my Barracuda and `18 Ram 2500 are exempt.

I just figure I'll rate my old car by year instead of mile. That way my 440 Challenger will rate better than my wife's Subaru BRZ.
