[QUOTE="4play, post: 2848004, member: 7223"] Strict emissions is most of it, it takes a ton of money just to get an engine certified, then they have to certify the rest of the vehicle for safety etc. Plus the majority of the US doesn't want diesel micro vehicles, they want trucks, SUV's, bigger and faster cars. Anyway, the EPA uses live exhaust emissions data, not "x" amount per volume or per gal emissions, they don't care if said engine/vehicle gets 10 MPG or 100 MPG for exhaust emissions, it must produce less than their set limits. Diesel engines are cleaner now than they were 10 or more years ago but they are using more fuel and/or DEF to provide the cleaner exhaust. So its possible a vehicle getting 100 MPG might fail to pass emissions for producing 0.1% more emissions vs a vehicle that gets 10MPG, even though it is by far more efficient in the real world.
