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 Grand Cherokee redesign delayed

The launch of the next-gen Jeep Grand Cherokee is being now being pushed back until late 2018 or even into 2019, Jeep CEO Mike Manley indicated Friday, according to Automotive News citing a Reuters report. Under the original five-year plan, the SUV was supposed to be replaced in the third quarter of 2017. That would have made for a big year for Jeep with a refreshed Renegade and new Wrangler also slated for 2017. A delayed Grand Cherokee could send ripples through Jeep's product plans. The three-row Grand Wagoneer is meant to give the brand a vehicle to take on the Land Rover Range Rover, but it's supposed to use the same platform as the Grand Cherokee. This change is rumored to push that important model's launch further back. There's less uncertainty when it comes to the next-gen Wrangler. Manley said that the model was "broadly on track," according to Automotive News. The five-year plan aimed for a launch in the second quarter of 2017. Controversy, however, has swirled over possible plans to move the Wrangler from its longtime Toledo, OH, factory. One problem Jeep doesn't have to worry about right now is sales. According to Automotive News, Manley said volume was up 20 percent globally and could reach 1.2 million by the end of the year. He also indicated the brand was "on pace" to reach its 1.9-million-vehicle goal for 2018. The Grand Cherokee delay comes in the wake of rumors that FCA US is shuffling around its previous five-year vehicle launch plan to postpone several models. Related Video:

Chrysler defies NHTSA, says it won't recall 2.7M Jeep Grand Cherokee, Liberty models

Facing a possible recall totaling around 2.7 million of its most popular SUVs, Chrysler remains insistent that the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty are safe vehicles. This comes on the heels of a recall request from the National Highway Traffic Safety Administration for these two models due to fuel tanks mounted behind the rear axle, which could possibly be ruptured during severe rear-end collisions, leading to an increased risk of fire. In response to the allegations, Chrysler says that it does not agree with NHTSA nor does it plan on recalling either vehicle.
Chrysler said both SUVs "met and exceeded" the requirements for fuel-system integrity, and cooperated fully with NHTSA since the investigation was opened in 2010. While 15 deaths and 46 injuries have been reported from fires caused by rear-end collisions on these models, Chrysler is claiming that the vast majority of incidents cited by NHTSA were "high-energy crashes," including one where a stopped Grand Cherokee was rear-ended by a tractor trailer going 65 miles per hour.
The automaker wraps up by saying "NHTSA seems to be holding Chrysler Group to a new standard for fuel tank integrity that does not exist now and did not exist when the Jeep vehicles were manufactured." Scroll down for Chrysler's official response to NHTSA, but we're pretty sure this isn't the last we've heard on this issue.
