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.

The fascinating history of the Popemobile

Pope Francis will be arriving today in the US for a variety of stops, including the World Meeting of Families in Philadelphia, PA. While here, the Pontiff won't be riding in the usual Mercedes-Benz Popemobile, but instead will make a more American switch to a modified Jeep Wrangler, according to the Washington Post. It'll feature a protected front, top, and rear, but the sides will be open for His Holiness to see the throngs of people gathering for him. For hundreds of years, Popes were transported in horse-drawn carriages or sometimes carried in an enclosed chair by footmen, but His Holiness finally traded for some real horsepower in 1929. While his ride sometimes varied depending on the country being visited, a Mercedes-Benz was generally the common choice. However, the Pontiffs have ridden in everything from a modified GMC Sierra to a Ferrari Mondial over the past few decades. Pope Francis has definitely preferred more plebeian transportation, though, including a Renault 4 running on biofuel. A trip to South Korea even put him in a Kia Soul, and he opted for an Isuzu D-Max in the Philippines. The Post's whole list is quite a fun read, and it's fascinating to see how the Popemobiles evolve over time. Related Video:

Chrysler adding 200 jobs at Ohio Jeep Wrangler plant

Chrysler is betting that the Jeep Wrangler will continue its strong sales surge as it continues to push the legendary brand out across the globe. The Auburn Hills automaker is reportedly adding 200 workers at the Toledo, Ohio plant that builds the Wrangler. What's more, those new hires will be at their posts quickly - they'll be on the job by April 1. Of those 200 workers, 130 employees will be there to relieve those who need breaks.
Why do they need so many relief workers? The Toledo Jeep Complex is currently working at a torrid pace with two ten-hour shifts. A third shift has been ruled out for the moment because of a production botttleneck - the plant's paint shop is already maxed out. According to Reuters, Wrangler production in 2012 cleared 200,000 units, and US sales were up by 16 percent.
Another part of the Toledo plant is presently down as Chrysler retools the line to build Jeep's divisively styled Liberty replacement, the Cherokee (seen in our gallery below). Production for the new model is scheduled to begin toward the end of May.
