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 Cherokee won't get diesel until sales of oil-burning Grand Cherokee improve

Okay Jeep fans, you want more diesel options? Time to step up and prove it. The only way Jeep will offer a diesel powerplant in the Cherokee, according to brand head Mike Manley, is if sales of the Grand Cherokee EcoDiesel nearly double.
Currently, about eight percent of the Grand Cherokees sold feature the 3.0-liter, EcoDiesel V6. That's simply not enough to warrant the bringing an oil-burning Cherokee to the US market, despite the vehicle's presence in Europe, where it's sold with a 2.8-liter diesel V6.
"Cherokee is slightly different because of its weight and size. When I think about bringing Cherokee diesel here, I would like to see Grand Cherokee diesel get much higher than eight percent," Manley told Automotive News. "It would have to be in mid-double digits."

Chrysler recalls 350k vehicles over ignition switches

Chrysler has announced a recall covering 349,442 vehicles due to ignition switches that can either become stuck or move without warning. All of the affected vehicles are from the 2008 model year, and were built before May 12, 2008.
The automaker has learned that ignition keys on some vehicles "may not fully return to the 'ON' position after rotation to the 'START' position during engine-startup," the company said in a statement. Additionally, "an ignition key may not fully return to the 'ON' position after rotation to the 'START' position and may inadvertently move through the 'ON' position to 'ACCESSORY' or 'OFF.'"
Chrysler says it is unaware of any related injuries, and notes that while reduced braking, engine or steering power is possible in such instances, the airbags are not affected. The later stands in contrast to General Motors' recent rash of high-profile recalls, and it's an important distinction that Chrysler (understandably) felt necessary to call out in bold print in its press release.
