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).

Jeep rocks the Wrangler Red Rock concept in Vegas [w/video]

The SEMA show may have once been all about dropping rides to the floor, but these days it's at least as much about jacking them up on lifted suspensions. And few show cars – or trucks, we should say – managed to embody that spirit at this year's tuner exposition quite as well as the Jeep Wrangler Red Rock you see here. The concept started out life as a Wrangler Unlimited, but instead of four doors, it has none. Or any roof, for that matter. Just a roll cage and a windscreen. What it does have are 17-inch wheels wearing 35-inch BF Goodrich tires and fitted to a suspension lifted by two inches. It also has a reinforced tailgate, power winch, tow hooks... everything, in short, that you could want or need for off-roading, and little more. As you can see, it also looks the business, with a custom hood, body-color grille, matte-finish bumpers, and a brown leather interior. Handsome as it is, though, its rugged beauty runs more than skin deep: lift off the sheetmetal and you'd find electronic locking differentials, a transfer case, and solid axles fore and aft. A more extreme take on the existing Jeep Wrangler Unlimited Rubicon Hard Rock edition, the Red Rock show truck was done up to honor the organization behind the Easter Jeep Safari that's a favorite among the legions of the Jeep faithful. And while it remains a concept only for the time being, a production version is slated to follow in time to celebrate the event's 50th anniversary next year. Related Video:

Chrysler investing $20M in Toledo plant to support 9-speed auto production

In 2011, Chrysler announced a $72-million investment in its Toledo Machining Plant to modernize production of the eight- and nine-speed torque-converters for automatic transmissions made there. That upgrade work won't be finished until Q3 of this year, but Chrysler has already announced a further $19.6-million investment to increase production capacity for the nine-speeders.
The extra units will be necessary because the nine-speed transmission they'll be mated to is going into three popular models: it will debut on the 2014 Jeep Cherokee, then go into the Chrysler 200 and Dodge Dart. The company predicted that this year alone it would sell 200,000 units equipped with the nine-speed tranny, and it is spending some $374 million in addition to the investment in Toledo to upgrade production capacity for it.
The work attached to this new investment won't begin until Q3 of 2014, and it will be finished by the end of that year. There's a press release below with all the details.
