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.

Chrysler recalling 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.

2014 Jeep Patriot and Compass ditch CVT for six-speed auto

It was reported in Automotive News a few months ago, but a new report on Allpar.com adds some details to news that the 2014 Jeep Compass and Patriot will get a six-speed automatic to replace the CVTs they currently use. According to a tip provided to Allpar, the 2014 models will begin production in March and be on sale sometime in the summer. The Jatco-sourced CVT in use until now - Jatco is owned by Nissan and Mitsubishi - has been often criticized, and many won't be sad to see it go.
The incoming six-speed automatic is said to be an all-wheel-drive cog-swapper that's the work of Hyundai and Magna and has been paired with the DynaMax AWD system used in the Hyundai ix35 and Kia Sportage. It won't be the only Chrysler product using a transmission with ties to Hyundai: the six-speed automatic in the Dodge Dart comes from Powertech, which is a wholly-owned subsidiary of Hyundai. With the Patriot and Compass said to be driving down the trail for the last time this year, it will be a short run for the new tranny and the rumored addition of a backup camera and power rear liftgate on the Compass.
