New E63 gets worse MPG than outgoing model that has a bigger engine!!
EU has strict CO (Carbon Monoxide) & CO2 (CarbonDioxide) Standards. Whereas the US has very strict NOX (Nitrogen Oxides) & PM (Particulate Matter) Standards.
With higher NOX and PM numbers you can achieve higher efficiency - Which leads to Higher Gas Mileage.
In the US they focus more on NOX and PM as to reduce health impacts and SMOG levels - Which leads to Lower Gas Milage
I just had no idea that it's a 30% difference in milage!

That's why GM small block has huge displacement, gets good mileage, and has lots of torque.
Just checked. The excise tax is now 40% in China for cars with engines over 4.0 liters. That can put you at a pretty significant disadvantage if not conforming (compared to a 25% excise tax on cars with engines from 3.0 to 4.0 liters).

Actually, it was my understanding MB (and Audi/VAG) went to 4.0 liter engines because of the onerous excise taxes scheduled to be imposed in China on engines over 4.0 liters. They all see that as such an important emerging market that they felt it made more economical sense to just conform their whole line of engines globally. It is surprising that BMW has bucked the trend keeping its 4.4.
it makes crazy torque at lower rpm (3k rpm) and it’s a higher displacement v8 Biturbo
