Wasn't there an EPA or Crash test data that showed an AWD Mazda6 was tested... I am still thinking we might see a Mazda 6 AWD wagon variant to compete with the new Buick Regal TourX Wagon.

There was crash test data for a 2018 AWD Mazda6, but it has since been taken off the website. I'll be really surprised if they unveil the wagon tomorrow, but with the recent arrivals of wagons to North America (there's also the beautiful Jag wagon), this might be a possibility. I just hope they will find a way to combine the AWD with the turbo on a Mazda6, regardless if it is in wagon form or not.
