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.

Chrysler investing $20M in Toledo plant to support 9-speed auto production

In 2011, Chrysler announced a $72-million investment in its Toledo Machining Plant to modernize production of the eight- and nine-speed torque-converters for automatic transmissions made there. That upgrade work won't be finished until Q3 of this year, but Chrysler has already announced a further $19.6-million investment to increase production capacity for the nine-speeders.
The extra units will be necessary because the nine-speed transmission they'll be mated to is going into three popular models: it will debut on the 2014 Jeep Cherokee, then go into the Chrysler 200 and Dodge Dart. The company predicted that this year alone it would sell 200,000 units equipped with the nine-speed tranny, and it is spending some $374 million in addition to the investment in Toledo to upgrade production capacity for it.
The work attached to this new investment won't begin until Q3 of 2014, and it will be finished by the end of that year. There's a press release below with all the details.

NHTSA upgrading Jeep Grand Cherokee, Dodge Durango headliner fire probe

The National Highway Traffic Safety Administration investigation into headliner fires experienced by a small number of Jeep Grand Cherokee and Dodge Durango owners has been upgraded to an engineering analysis, the step before the initiation of a recall. In August last year the investigation began with 146,000 Grand Cherokees from 2012 after three complaints were received, but a report on Edmunds says it has been expanded to include 593,299 vehicles covering the 2011-2013 model years for the Jeep and the Dodge Durango, which uses the same headliner assembly, because of possibly 52 incidents of fire.
In some of those incidents drivers have reported a burning odor, smoke or open flames that were contained to the headliner or migrated to another area of the passenger compartment. The culprit has apparently been found: NHTSA blaming an electrical short in the sun visor vanity light wiring, which is routed under the headliner and held in place by three screws. Chrysler began its own probe into the issue when it was first reported and is still looking into the situation while, "fully supporting the National Highway Traffic Safety Administration's investigation."
