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.

Jeep Chief and Wrangler Red Rock Responder teased ahead of Easter Jeep Safari

Jeep is being coy about it's lineup for the 2015 Moab Easter Jeep Safari, releasing just a pair of shots and an exceptionally brief press release on two of the seven concepts coming to the desert later this month. So, what can we glean from the limited assets that have been given to us? Well, as we said, we know Jeep is bringing seven vehicles to its big festival. We also know the names of two vehicles, shown above – there's the Chief and the Wrangler Red Rock Responder. Which is which? A fair question. We're betting the second image is the Wrangler-based Red Rock Responder. As for the Chief, well, we've absolutely no idea what to expect there. Jeep's Moab concepts generally include the model name on which their based – see the Grand Cherokee Trail Warrior and Cherokee Dakar from last year, or even the Wrangler Red Rock Responder, mentioned above. There's no such moniker on the Chief. As for the Chief's illustrated teaser image, as we said, it doesn't reveal much. The body is angular, and quite Jeep like, with squared-off wheel arches and decidedly old-school taillights. Beyond that, though, we don't have much to go on. Expect much more not just on the Chief and Red Rock Responder, but on all seven of the concepts Jeep is bringing to Moab. The party starts on March 28 and runs until April 5.

Daily Driver: Long-Term 2014 Jeep Cherokee

As a fan of the boxy Jeep styling of old, I was disappointed when photos first leaked of Jeep's revived Cherokee in early 2013. Then the midsize crossover arrived in Autoblog's longterm garage in May of 2014 and my opinion did a 180. I was prompted to rethink the exterior design of the vehicle after reading our reviewer's interview with head Jeep designer Mark Allen. "The previous, blocky Cherokee was so aerodynamically inefficient, it would be wrong to do it," Allen told Autoblog's Jonathon Ramsey. That made sense. After all, Jeep is a brand associated with the outdoors, so its only natural that they seek to produce efficient, yet capable vehicles. It was then I began reconsidering the sleek lines of the new Cherokee. What once seemed bland and rounded now appeared streamlined and purpose-built. I also give Jeep credit for the slim headlamp silhouette, which look like no other SUV on the market – a far cry from the distinct circular lamps on Wranglers or squared headlights of past XJs. As I drove our long-term Jeep Cherokee Trailhawk on a few road trips, my affinity for the vehicle's comfortable interior grew as well. The seats held up to a nine-hour trek to Montreal, and the Chrysler Uconnect system made navigating the roads and the radio a breeze. Above you'll hear my early impressions of the Cherokee, and below you'll find a previous long-term update featuring Autoblog's Steven Ewing and Chris McGraw. UPDATE: The video mistakingly indicates that the Jeep Cherokee features LED headlights. The Jeep Cherokee, in fact, has daytime running lamps with LED accent lighting. Related Video:
