Dirt Every Day tries to find the best 4x4 for under $4k

If you want to build a cheap truck that can still do dirty deeds off the beaten path, it's best to start with solid axles and a solid V8 engine. That sums up the lessons learned after watching the 2014 Cheap Truck Challenge from the Dirt Every Day video crew, who took to the deserts and surrounding areas near Reno, NV, in an attempt to find the best 4x4 for under $4,000. Fortunately for us, the whole sordid journey was captured on video.
This isn't the first time the boys from DED filmed a Cheap Truck Challenge, and this year's festivities pitted together a 1993 Chevy S10 pickup, a 1995 Jeep Grand Cherokee and a 1975 International truck in a series of challenges ranging from donuts to drag races, with plenty of hill-climbing and rock-crawling action in between. We don't want to spoil all the fun, but suffice it to say one competitor was found to be lacking while the other two performed (mostly) well. See for yourself in the video above.

NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.

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.
