They aren't replacing SRT with Trackhawk, they are moving SRT to only be a Dodge brand thing, and making Trackhawk the equivalent for Jeep. So for Jeep its a replacement, but in the larger picture SRT still exists.

A Jeep retuned for high performance on roads and tracks could perhaps more sensibly be called a Trackhawk than an SRT, with Dodge having three SRTs now (and due to get two more), and Chrysler and Jeep having just one each.

Where did this information come from? I read about a Hellcat engine going into the Grand Cherokee, but I haven't rad about his anywhere but here.Renegade Trackhawk
