A wagon version of the North American Passat will be an all new undertaking. Unless development has already started, my guess is that it will be a MINIMUM of two model years before we see it rolling off the assembly line. So, 2014 at the earliest, more likely 2015. And the longer VW waits to green light a Passat NMS wagon variant, the longer it will take to show up for sale.
One thought I had recently was a way for VW to bring us the European Passat Wagon. Market it as a CC wagon, or CC Sportwagen if you want. That way, its price (and Euro chic) would fit in with the rest of the true Euro lineup. Of course, that means we will be paying mid to upper 30's for a nicely equipped Passat Wagon with the TDI motor. But it will be the real deal--Euro all the way--and we could have it within one model year.
I think I would recalibrate my finances in order to buy one. In a heartbeat.
As for the TDI Tiguan, well go figure. The excuse has always been that to put the 2.0TDI in the Tiguan, VW would have to go to different emissions setup (read: Urea injection) because of the higher loading on the engine. Well gee, they have had to do that in the NA Passat for pretty much the same reason. So now that they have the exact powertrain they would need for a TDI Tiguan, in production in the NA Passat, (and the rest of the parts running around Europe in TDI equipped Tiguans), VW's excuse is...what? :ugh
