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.

Fiat 500X poised for Paris catwalk

We've known for some time that the new, Fiat-based baby Jeep (which may or may not be called the Jeepster) is set to arrive at the 2014 Geneva Motor Show. What we weren't sure of was whether its platform mate, the so-called Fiat 500X, would be doing so alongside or at a later date. Well, according to Reuters, we'll get to see the first all-wheel-drive 500 later this year in the City of Lights.
Yes, we can expect the 500X to arrive at the 2014 Paris Motor Show, according to an official with an Italian trade union. The unnamed source cited retooling at Fiat's Melfi factory, in southern Italy, which currently produces the Grande Punto. It's expected that the newest member of the growing 500 family will replace the Suzuki SX4-based Fiat Sedici, although when the X will go on sale remains an open question.
According to Reuters, both the Jeepster and 500X will be built alongside each other in Italy. Whether the 500X will cross the pond with it's slat-grilled cousin, though, remains to be seen (we're leaning towards yes).

Jeep Liberty under investigation for door fires

The Jeep Liberty has already had plenty of attention for possible fires thanks to the first-gen model's fuel tank, but now the midsize Jeep is under the microscope of the National Highway Traffic Safety Administration for another fire-related concern. NHTSA has opened an investigation for the 2012 Liberty after receiving two reports of electrical fires in the driver's door.
According to the investigation summary, around 80,000 vehicles could potentially be affected by this problem. In both reported fires, the drivers noticed smoke and then flames from the master power window switch, and they had to pull to a stop and exit through the passenger side of the SUV. According to Autoguide, there was one injury to a motorist who suffered burned fingers while trying to open the driver's door.
Interestingly, the Dodge Nitro is not yet involved in this investigation, even though it was still around for the 2012 model year; the Nitro ended production in 2011 about a year before the final Liberty rolled off the line for the 2013 model year.
