Will Trackhawk make 700 hp?

Even before the first Hellcat-equipped Dodge Challenger was shown to the public, there has been speculation on what a Jeep Grand Cherokee Trackhawk with a Hellcat would be like.

(Grand Cherokee SRT shown.) At first, we were told that the Trackhawk might not even be produced, because the Grand Cherokee is an upscale car and the engine was just too noisy; but the Hellcat is quieter than it was when in development trim, and that’s no longer a major issue. Nor is the supply of key parts.

At first, we assumed that the engine was have to be downrated rather dramatically to make all wheel drive possible. How tough can you make the transfer case and still have it fit under the car? We speculated that it would end up at around 640 horsepower, based on the capacity of existing components from various parts makers.

Now, though, reliable sources have posted that the system will make a full 700 horsepower. That means either they’ve found tougher transfer cases (and other parts) that still fit in the Grand Cherokee and aren’t far too pricey; or that they’ve gone the “heavy-handed torque management” route.

Keep in mind, though, that the official rated horsepower might be lower, e.g. 680. That 700 might be an estimate, or a “roughly,” or even gross power (before accessories). Regardless, as we’ve said before, even the low-end estimate we originally had — 640 hp — would be far, far above the current, highly regarded 6.4 horsepower Grand Cherokee’s power.

There’s little sure information about the Hellcat Trackhawk for the moment. We are fairly sure that it will debut in New York City, taking its place alongside the Demon for the most powerful launch in automotive history; but we’ve seen nothing concrete yet.

Does the TRX presage a Jeep Trackhawk Hellcat?

The Ram TRX is the first publicly-shown vehicle that hooks up the Hellcat engine to a four wheel drive system. It dropped down to 575 hp, but that’s a hundred horsepower more than the 6.4 Hemi and even further above the Ford Raptor.

A Hellcat-powered Jeep Grand Cherokee Trackhawk has been rumored since before the Hellcat was even shown to the public. Insiders said that FCA leaders were concerned the engine be too loud or uncouth for the refined Grand Cherokee, and that the cost would be too high.

The supercharged Hemi turned out to be relatively quiet, and easily controllable — surprisingly so, in fact. It might be hard to whip it around corners at speed in the big Jeep, but at least it’ll be possible to drive it gently.

That left durability, and the TRX is our first look at how that’s being handled. Dialed down to 575 horsepower, it seems to be compatible with many factory parts. The differentials are possible issues; so is the full time AWD transfer case. The TRX uses a part-time Borg-Warner 44-45; there is a full-time B-W 44-44, but Jeep already uses the formerly-New-Venture-now-Magna MP3010 on its SRT. Can full time four wheel drive work with 575 horsepower, while still fitting into the Grand Cherokee?

There are still many questions, but sources have told Allpar that there are Grand Cherokee Hellcat mules running around, and that the Hellcat would be detuned for the purpose. Whether they turn out to be “commercial” — practical for commercial sale — is still up in the air. See the Ram 1500 Rebel TRX.
