We're all aware of the delays bringing the Skyactiv-D to market in the Mazda6. It's now almost a year overdue from the originally-targeted on-sale date. The latest is we're being told is that the powertrain is not meeting drivability expectations for the U.S. market. I'm wondering if this is because Mazda so far is refusing on going to a urea SCR catalyst system. Aggressive EGR application in diesels is known to affect performance, whereas going to an SCR would theoretically improve performance and drivability, but would take away the Skyactiv-D's distinction of being the only diesel on sale that doesn't require SCR. The VW TDI in the Golf and Jetta don't have SCR for 2014, but will reportedly have it for 2015.
My question for you guys is, would it be a deal-killer if the Skyactiv-D were to get SCR for the U.S. market? Would you rather have increased performance with SCR, or slightly less performance and no SCR? Personally, I'd still be interested, because I've had a positive ownership experience with Mazda, and am generally interested in diesels. I would be slightly disappointed that Mazda wasn't able to figure out how to balance performance and emissions without SCR, but it wouldn't automatically disqualify it from my consideration. What are your guys' thoughts?
