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.

Jeep Trackhawk: 600 hp?

The Dodge Challenger and Charger both have Hellcat engine options, bringing 707 horsepower to the cars. The Jeep Grand Cherokee Trackhawk has long been rumored, and sources say it will indeed have the same engine, but without the same tuning.

There could be several reasons why it would be detuned somewhat:

Cooling is a major issue with this amount of power, and the Hellcats have goals of high consistency at full power. Competing cars from Chevrolet and Shelby have been slammed for throttling back on the power as they quickly heat up at the track.

The Jeep, unlike the others, is rumored to be all wheel drive, which could allow quicker launches — but would put more stress on the entire system. The engine may have to be tuned to put out the power that can reasonably and economically be handled by the drivetrain and suspension.The Grand Cherokee has a higher center of gravity and too much power could be dangerous.

Regardless, a Jeep Grand Cherokee Trackhawk packing even 580 horsepower would be a major boost over the current 485 horsepower SRT model, and would likely attract even more attention from those who would normally go for a German crossover.

FCA US has already applied for a trademark on the Trackhawk name. The application has passed all the legal hurdles and USPTO approval of registration is now waiting for the company to file a Statement Of Use (SOU) in commerce.

Get a Jeep Grand Cherokee SRT Before it’s too Late

Back in May Chrysler made some announcements about their enthusiast-focused SRT brand. They had spun it off as a separate division but that didn’t work out so well so they decided to reconsolidate it as part of Dodge.

But this move resulted in a lot of questions, chiefly what would happen to other high-performance vehicles in the company’s portfolio including SRT versions of the Jeep Grand Cherokee and Chrysler 300 sedan? Answering part of this query, it appears as though the big, bad Jeep is sticking around, for the time being at least.

Model year 2015 Grand Cherokee SRTs can be ordered by dealers, but for how long is anyone’s guess. A few months back the company filed to trademark the name “Trackhawk,” which is rumored to replace the SRT version and go on sale in 2016.

The introduction of this and other special-edition models could coincide with the Jeep brand’s 75th anniversary, which takes place in the same year. The SRT Jeep Grand Cherokee starts at around $65,000 and features a 475-hp, 6.4-liter V8 engine.
