Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

Chrysler registers Trackhawk trademark

There may not be many ways to forecast what an automaker is planning for the future, but there are some. Trademark applications are one of them, and Chrysler has just applied with the US Patent and Trademark Office to protect the name "Trackhawk." The question is, what's it planning on using it for? We don't know for sure, but we can put together an educated guess or two. And one guess is that Jeep will use the name to replace the letters SRT on the performance version of the Grand Cherokee.
How do we figure, you ask? From a number of developments. For starters, the SRT division has been reintegrated into the Dodge brand. Those letters currently appear on only two vehicles from outside the Dodge lineup: one is the Grand Cherokee SRT, and the other is the Chrysler 300 SRT. We've heard ruminations (however unconfirmed) that the latter could be either discontinued or possibly relabeled, and if the same proves true of the GC, the Trackhawk name could serve as a on-road performance counterpart to the Trailhawk label applied to off-road versions of models like the Cherokee and Renegade.
Logical it may be, but it's hardly a foregone conclusion. The Trackhawk name could just as easily be used for a new concept (like the Trailhawk name was in 2007), for another kind of trim level or for something else entirely. In fact we don't even know for sure it'll be used by the Jeep brand specifically, or used at all for that matter. Automakers have been known, after all, to register names they don't end up using.

Jeep going bigger with new Grand Wagoneer, smaller with sub-Renegade?

The headlines are still rolling in for the new Renegade that Jeep unveiled at the Geneva Motor Show last week, but already reports are surfacing, citing sources within the company, about what Chrysler's iconic off-road brand will do next.
Speaking with Auto Express (whose reports we tend to take with a grain of salt or two), Jeep chief Mike Manley suggested that two courses of action are currently under consideration at Auburn Hills to develop two very different new models - one smaller and one larger than anything Jeep currently makes.
One plan would be to make an SUV or crossover even smaller than the new Renegade, although it isn't immediately clear what platform it would take. The Renegade (pictured above in Trailhawk spec) will be built in Italy alongside Fiat's upcoming 500X, but uses a heavily modified platform. We figure the smaller model, if approved, could base itself on the new Fiat Panda Cross.
