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.

Marchionne may stay with FCA until 2020

We might get to see Sergio Marchionne and his vast array of sweaters in the auto industry for even longer than expected. The FCA CEO suggested last year that he would retire from the automaker when its current five-year plan was complete in 2018. Now, he has tentatively extended that point out to at least 2020. "I can do this for another five years if you push me, right? Beyond that, I ain't gonna do it, and I don't want to," he said to Automotive News. That would give Marchionne a 16-year career at the top from joining Fiat in 2004 to possibly leaving FCA in 2020. Although, take the CEO's statement with a grain of salt because he has made multiple statements about the timing for his retirement. In 2012, Marchionne said he would only remain in charge until 2015, which is, well, now. Those five years might also go quite quickly because Marchionne is a busy guy with the Ferrari IPO, the attempted merger with General Motors, implementing FCA's five-year plan, and many other projects. He's already considering the next CEO, though. "My purpose in life is to find the Kuniskises of the world, the Manleys, the Biglands, the Palmers," Marchionne said to Automotive News, referencing the heads at Dodge, Jeep, FCA North America, and the company's chief financial officer, respectively. "I told them, 'One of you is going to do what I do one day. I don't know who that is, but one of you is going to do it.'"

Jeep Cherokee appears in Chrysler's second Super Bowl spot

The second of three spots produced by Fiat Chrysler Automobiles for this year's Super Bowl featured the all-new 2014 Jeep Cherokee. Aired during the game's half time show, the minute-long ad didn't strike as anything new or innovative from an automaker with a reputation for above average Super Bowl spots, but it did show the controversially styled Cherokee in the best light possible.
