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.

Consumer Reports digs Mazda3, disses Jeep Cherokee

Consumer Reports has just rendered its verdict on two of the more important cars to launch this year - the Mazda3 and the Jeep Cherokee. Considering the value a "Recommended" rating carries with the public and the viciously competitive markets these two cars compete in, Consumer Reports' view could have some impact on their initial success.
For Mazda, that's a good thing. CR spoke quite highly of the Zoom-Zoom brand's compact sedan and hatch, testing both models, and citing the excellent fuel economy and snickety-snack manual shifter as high points. Downsides to the 3 included a ride that is agile but "nervous," a bit too much noise and a cramped back seat. Still, the 3 was good enough to earn its place in the ranks of the "Recommended."
The Jeep didn't fare quite so well, with CR calling the polarizing CUV "half-baked." Although both engines were tested, the magazine called the 2.4-liter four-pot underpowered and its nine-speed automatic unrefined and unresponsive. That's particularly damning, considering the 9AT's role in future Chrysler products, including the extremely important 200. Overall, the Cherokee missed out on the coveted "Recommended" rating.

Freak accident during Jeep demonstration turns fatal

A 20-year-old woman was killed in Edmonton, Canada on Satuday, reports CTV News, in a freak accident resulting from a rollover during a Jeep demonstration. As part of a fundraising enthusiast event called "Jeeps Go Topless," the driver of one Jeep Wrangler drove up and onto the top of the tire of another.
CTV reports that the owner of the topmost Jeep then switched the vehicle off, posed for pictures and then dismounted from his vehicle. His movement off of the Jeep apparently caused it to tip over, crushing a woman who was on top of an adjacent vehicle. Edmonton police are currently investigating more fully what caused the parking lot accident to occur. Scroll below to watch the CTV News video report about this tragic incident.
