I'm not sure what you're saying about mpg, Richard. On both sides of the pond,
emissions regs are based on stuff spewed out of the exhaust pipe *per unit
distance driven*, no matter what the engine displacement is, or the fuel
economy.
As a matter of fact, the whole deal about grams of carbon emitted, that
Europeans have started using as a new standard, is in fact 1:1 related to fuel
economy anyway, for any given fuel type. So the US CAFÉ (ignore the idiotic
accent that doesn't apply here) mandates accomplish the same thing.
The sulfur content in diesel sold in Europe today might be lower, at least
temporarily, but the particulates regs are more stringent here. So it's a mixed
bag.
