The List: Best of proving grounds

Proving grounds are where automakers and enthusiasts alike go to push their vehicles to their mechanical limits. The Rubicon Trail, located in the Sierra Nevada, is the ultimate off-road test, while Germany's Nurburgring is a grueling 13 mile road and track course. Jessi and Patrick visit both iconic proving grounds in this "best of" compilation of The List.

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).

Final Toledo Jeep decision may have nothing to do with city's efforts

Toledo, OH is doing all that it can to keep production of the Jeep Wrangler in its boundaries, but the biggest issue facing the plant may be insurmountable, no matter how desperately the city wants to keep the Wrangler local. The Wrangler is built in a rather interesting manner at the Toledo Supplier Park: Fiat Chrysler only handles the very final assembly of each vehicle, while two other companies, Kuka, a German firm, and Hyundai-Mobis, a member of the sprawling Hyundai empire, produce the body and chassis, respectively. The vehicles are then transferred over to the FCA part of the park, where they're painted and completed. This was, as The Detroit News explains, a convenient arrangement back in 2006 when the supplier park opened. Chrysler, which was still owned by Daimler at the time, arranged for Kuka and Mobis to handle production, saving it a huge sum of money. Both suppliers own their own machinery and buildings and employ their own workers. Now that FCA is a relatively healthy entity, though, there's not a lot of need to be sharing profits with two other companies. "What [FCA boss Sergio Marchionne] would like is to have the advantages of high-capacity utilization, owning that capacity and taking advantage of that for himself versus having a supplier doing some of the things his competitors do internally," David Cole, chairman emeritus at the Ann Arbor, MI-based Center for Automotive Research, told The News. "It really adds another level of complexity to the situation." While Sergio Marchionne is a man that generally gets what he wants, it seems unlikely that either Mobis or Kuka would give up their role quietly. According to Jon Zapf, Mobis North America's chairperson for UAW Local 12, the company "definitely wants to maintain their part of this production process." According to The News, Jeep is likely to announce the location of next-generation Wrangler production in June. Expect to hear much more on this one in the coming months.
