Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

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.

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.
