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 recalls 2013 Ram pickups, 2014 Jeep Grand Cherokee

Chrysler's spate of successful products is about to be marred by a trio of recalls. The Pentastar is recalling 51,477 Ram trucks and Jeep SUVs. According to the National Highway Traffic Safety Administration, there have been no reported accidents, injuries or deaths related to the affected vehicles.
The largest action covers the Ram 1500, which is seeing 45,961 trucks being recalled. Models built between June 26, 2012 and February 5, 2013 are being recalled due to a potential software issue in the electronic stability control. Apparently, the system can be randomly deactivated upon vehicle startup.
Chrysler is also recalling 4,458 2014 Jeep Grand Cherokee models. Covering everything but the SRT models, the potentially defective SUVs were built between January 14 and March 20, 2013. This recall focuses on "premium headlights," which means cars equipped with LED running lights. During the switch from the bright daytime running lamp setting to the low-intensity parking light setting, an electrical spike can cause one of the Jeep's computers to go into a safe mode, turning off the LEDs. This violates Federal Motor Vehicle Safety Standards.

Chrysler recalling nearly 141k vehicles over electrical woes

Software glitches that randomly illuminate warning lights and cause instrument cluster blackouts are forcing Chrysler to recall 140,800 vehicles, The Detroit News reports. The automaker is recalling 132,000 2014 Jeep Grand Cherokees, 91,559 of which are in the US. In addition to the Jeep recalls, Chrysler is adding 10,800 2014 Ram 1500, 2500 and 3500 trucks to the list for similar problems.
Chrysler reportedly says, "Both events occurred infrequently and appeared to resolve themselves by tuning the vehicle's ignition off and then on."
Engineers discovered a problem with the anti-lock-braking system software that causes the instrument cluster display of the Grand Cherokee to illuminate warning lights and black out - even its ABS and electronic stability control systems are affected. To fix the Jeeps, Chrysler will update the vehicle's software.
