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 Wrangler Copper Crawler is our idea of a restrained Mopar shopping spree

According to a recent report, the Jeep Wrangler is the most popular SUV for customization, and this is backed up by the fact that the iconic off-roader was just named the Hottest 4x4-SUV at SEMA for the fourth year in a row. Looking for ways to keep its customers in-house rather than going aftermarket, Jeep and Mopar are always teaming to offer exciting new parts and pieces for the JK Wrangler.
Compared to most other Wranglers on display at SEMA - as well as other Chrysler Mopar SEMA concepts - the Jeep Wrangler Copper Crawler is surprisingly reserved, but should be no less exciting for owners to give their Wrangler a distinctive look. Starting off with an eye-catching copper paint scheme, the Jeep then goes on a Mopar catalog shopping spree with its matte black grille, black beadlock wheels, two-inch lift, Rubicon bumper (with a winch and aero end caps up front) and rocker panel and taillight guards.
Jeep also upgraded the Wrangler's transfer case for low-speed rock crawling (hence the vehicle's name) and cold-air intake for extra measure.

Jeep Begins Fixing 1.56 Million Recalled Grand Cherokee, Liberty SUVs

Chrysler is just now beginning the big job of fixing 1.56 million older Jeep SUVs seven months after a recall was announced, according to The Detroit News. Jeep Grand Cherokees sold between 1992 and 1998 and Jeep Liberty models sold between 2002 and 2007 are being recalled because the gas tank can leak in the event of a rear-end collision, leading to a fire. The National Highway Traffic Safety Administration originally requested the recall of 2.7 million vehicles. Chrysler initially disputed NHTSA's findings and seemed willing to go through a court battle until an 11th-hour deal reduced the number of vehicles involved in the recall. The remaining vehicle owners left out of the recall will receive a "customer service action" notification and may not get fixed. Chrysler says the vehicles are safe and need no repairs. Fixing the 1.56 million Jeeps will cost Chrysler $151 million. NHTSA cited 51 deaths causes by such tank fires. Chrysler plans to install protective trailer hitches to protect the gas tanks, but even the automaker admits the hitches will only provide incremental protection in a low-to-moderate speed rear-end crash.
