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).

FCA recalls 1.1 million vehicles worldwide due to confusing shifter

Fiat Chrysler is recalling 1.1 million vehicles worldwide to address the problematic shifter used on cars with eight-speed automatic transmissions. The issue is that the console-mounted shifter acts like a rocker switch and always returns to the middle position after moved. This has been deemed confusing to drivers – confusing enough to cause some to exit their vehicles without first selecting Park and leading to the car rolling away. FCA says 41 injuries are related to the shifter problem, and no evidence of equipment failure has been found. The company will enhance warning chimes and alter the shift strategy, meaning alert messages will be displayed in case the driver door is opened while the engine is running. With the door open, the transmission will prevent the car from moving even if Park is not selected. The affected vehicles are certain model-year 2012–2014 Dodge Charger and Chrysler 300 sedans, as well as model-year 2014–2015 Jeep Grand Cherokee SUVs, an estimated 811,586 US vehicles in total. The recall also affects 52,144 vehicles in Canada, 16,805 in Mexico, and 248,667 vehicles elsewhere. The shifter is used with ZF-designed and ZF-built eight-speed automatic; Audi uses a similar shifter setup in some of its vehicles, including the current-generation, which predated Chrysler's use of it. Chrysler uses a different, a rotating-dial-type shifter on eight-speed-equipped Rams. The company moved away from the problem shifter design in 2015 for the Charger and 300, and the Grand Cherokee's shift lever was modified for 2016. Owners of affected vehicles will be notified of the recall when service is available. Fiat Chrysler urges customers to follow the instructions in the vehicle's owner's manual in the meantime.

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.
