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 teases upcoming outlay of SEMA cars

Fiat Chrysler Automobiles is hauling a multitude of modified models to the annual SEMA show in Las Vegas this November, and the company is releasing the first teasing sketches of many of them.
Unfortunately, FCA isn't giving many solid details on any of the concepts other than saying the vehicles from Chrysler, Jeep, Dodge, Ram and Fiat all benefit from tuning from its Mopar performance brand. The teaser photos include a sinister-looking Chrysler 200S, Fiat 500 Abarth with two-tone paint and a scorpion on the hood, a red and black 500L, seemingly two different takes on the Jeep Renegade, a green Dodge Challenger wearing the T/A badge, an orange and black Dart, a very neon Charger, just the outline of a red and black Viper, a Ram ProMaster in Mopar livery and a Ram pickup called the Outdoorsman.
Take a look through the gallery to see what you think of the sketches for these concepts, and scroll down for the full announcement from FCA.

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.
