I actually think this is pretty cool. But I would want a regular GC Trackhawk and a GC Trackhawk Pickup side-by-side. This looks like something that would be production already, very clean, the lines work, it's seamless and looks normal.
Doesn't seem like the link wants to embed. But anyhow, it does look good, and I think that's something they could actually produce and make money off of. The pickup market in NA is booming, has been booming, it's great. I think it would fair very well. That being said, It would be very different than your regular F-series and Ram1500, etc. Which could pose to be a good thing. However, with the Wrangler pickup coming out soon, it may not be a smart decision to bring em' both out.
Best thing for Jeep to do if they want to kick it up a notch is to offer a trim that has some level of luxury going on. Can't be hard to do that and do it incrementally. With the luxury SUV/Truck segment growing it just shows how strong the market is out there. Jeep can do it.
I highly doubt we'll be seeing a trackhawk pickup anytime soon as Jeep is coming out with the Wrangler based pickup first. A Hellcat powered pickup would be great in straight lines but if it's based on the Trackhawk, then it'll probably be good for "track" only.
It'll be a pickup that you can use on the 1/4 along with daily street driving. I can't imagine throwing a trackhawk pickup on a circuit of any sort lol. But you're right, we won't be seeing it for a long time anyhow if it even comes to light.
