Well, seeing is believing. We have been looking at TrackHawks all along. And Mike Manley, Jeep's CEO, wasn't selling the world a bill of goods when he said to expect the thing "by the end of 2017". As you can clearly see in the slightly noisy engine shot, that's a supercharger parked on top of FCA's 6.2-liter V8, just like in the Charger and Challenger Hell-twins. Chances are it'll make the same power as it does in those two – 707 hp, in case you're just waking up from cryo-stasis and aren't aware of the most famous power output figure on the planet.
There are some differences between this Grand Cherokee and ones we've previously pegged as TrackHawks. The fog lights in the lower grille vents are gone, and the rear fascia gets a bit more aggressive. Perhaps these will be the external details that separate the TrailHawk from the lowly non-supercharged SRT versions. We've also been hearing about quad exhaust tips, but haven't seen them on a prototype yet.
If Jeep wants to get this thing out on the road by the end of the year, we're likely to see it coming to an auto show soon. Keep your eyes peeled.
