The 2014 Mazda 6 diesel has reportedly been delayed until April 2014 due to emissions testing delays. I'm wondering if Mazda is actually having a tough time meeting emissions standards without the use of DEF. How committed do you think the company is to bringing it to market without having to rely on an external aftertreatment? What would be a bigger failure for Mazda: If they ultimately have to use DEF to meet emissions, or cancelling the 6 diesel for North America because they can't meet emissions without DEF? Do you think the 6 will ultimately come to market in North America without needing DEF?
