BMW, Mazda, M/B, Mini have had Euro Step VI diesel vehicles on sale for months, some at least 28 months ahead of requirements, 84 of them to date. I think Mazda was the first.
There were NO gasoline machines that were certified to meet that level of "cleanliness" until the the last 2 weeks. And to date there are only 38 as clean as the diesels ... all from BMW, M/B, Mini.
Even your "super clean" US gasoline exports can not meet Euro Step VI, at least not so far.
Further, I doudt more than a couple of current US powerfrain technologies even have a chance at meeting the 2015 EU CO2 requirents.
As for your "cancer scare", I hope you understand that the fine sub-PM2.5 particle matter and volatile hydrocarbons from advance gasoline enigines are generally a greater risk to environment and health than current advanced diesel emissions. You need to look at data later than pre-2000s coal mine studies...
And as kts350 also pointedout
Of course he is refering to an engine with a displacement in the 2 Liter range ... not 4~6 Liters which for obvious reasons are FAR more expensive ... if for no other reason than higher development costs spread over substantually lower volumes.Price difference between petrol and diesel models is $1000.
Edit: All diesels currently rated Euro Step VI are <3.0 Liters. Further, the gasoline Euro Step VI machines are equiped with engines <2.0 Liters.
What would that do to the US HP/torque game to be as clean as the EU machines?
As I see it ... the only thing keeping a FLOOD of non-US diesels out of the US is NOx ... and Euro Step VI (4Q2014) is getting VERY close.
