Cadillac Wagon.

A proper Cadillac wagon was just a crazy dream until Cadillac actually came up with one, in 2008.
It was part of the new, second-generation CTS sedan. The new CTS was available as a 4-door sedan of course, but also as a much more modern-looking 2-door fastback coupe. As well as an almost weird-looking Sport Wagon.
The new wagon model was introduced in 2010. And I think it looked great, and was quite a gutsy move from GM. It was mostly available with the smooth 3.6 Liter V6, with either RWD or even AWD. (Even the 2 door coupe was available with AWD!). I personally drove the crazy 556HP V version of the wagon for a week, and it was great.
The CTS wagon has developed a bit of a cult over the past years, as it is pretty rare these days.
Now all Cadillacs from the North American market will be based on the Ultium platform, at least for the next few years. Of course, so far the new models introduced area ll SUVs, Except the $340,000 Celestiq. And we know Cadillac has been working on 2 brand new EV sedans based on the platform. In China, a few manufacturers are already offering EV wagons. Audi just unveiled the great-looking Audi A6 e-Tron Avant, which is a fantastic-looking EV wagon… However, it will not be coming to the US.
I truly think that once the sedans are out, it wouldn’t cost GM a fortune to come up with a wagon body style.

It; ‘s almost there already, since they’ve already shown a Buick Concept wagon for the Chinese market that will probably end up as a production model sooner rather than later.
All I can say is, why not?
