They are different terms, but I don't think the difference has much to do with power or CO2 emissions. An entry level Rolls-Royce has emissions of about 343g/k

They are different terms, but I don't think the difference has much to do with power or CO2 emissions.
An entry level Rolls-Royce has emissions of about 343g/km, and the Veneno supposedly 499g/km.
They both have V-12 engines of broadly similar size and power.
For comparison one of the most efficient hybrids (I looked up my car) with a gas engine emits about 115 g/km.
