I don't think there would of been that many diesel variants ordered as thjey would of known the uptake would of been slow. Plants can changes their production plans. Look at Holdens Adelaide plant. It produced the Chevy SS all December 2016 so they could make sure the first MY17 Australian vehicles were actually built in 2017. My Redline came off on day 2 in 2017. The Chevrolet SS started MY17 in 2016 while the AU version was actually 2017.
