2014 Jeep Grand Cherokee gets surprisingly comprehensive update, new diesel power

Traditionally, automotive journalists can be heard muttering something to the effect of "Geeze, it's about time!" whenever a vehicle's midcycle refresh is revealed. As we routinely see and drive new models many months before the public even claps eyes on them in showrooms - and then go on to tweeze apart their minutia in our daily writings - perhaps some impatience is to be expected. With so much exposure to a given vehicle, it's fair to say we tire of most cars and trucks far more quickly than the average consumer.
The alterations are handsome, if not subtle touches from the "If It Ain't Broke" school of design.
Which is why we're pleased to say "Oh, is it time for that already?" when it comes to the 2014 Jeep Grand Cherokee. The current WK2 Grand Cherokee hit the market in 2011 and climbed its way into our hearts with its rugged good looks, go-anywhere capability and surprising refinement. We're not yet tired of its appearance or performance, but even so, we're very glad to see Chrysler giving its flagship Jeep some attention, including a much-anticipated diesel powertrain option and some other economy-minded measures.

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:

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.
