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.

2014 Jeep Grand Cherokee pricing leaks out

With our deep dive and auto show coverage of the 2014 Jeep Grand Cherokee revealed at the Detroit Auto Show, we brought you as much information as Chrysler would allow us to, but one thing we're still left in the dark about was the pricing. It would seem that Jeep Garage might have the answer for that. The Jeep enthusiast forum claims to have gotten its hands on the ordering and pricing breakdown for the updated Grand Cherokee, and while a Jeep representative has yet to get back to us as to the validity of the site's claim, these preliminary numbers look pretty kosher to us.
In base form, the two-wheel-drive Laredo will reportedly start at $28,795, which is a $1,100 increase over the 2013 model year, and the new Grand Cherokee Summit trim level starts at $47,995 for 4x2 models and $50,995 for the 4x4. Waiting for the new diesel engine? The torquey new 3.0-liter oil-burner will be a $4,500 option on Limited, Overland and Summit 4x4 models, but 4x2 pricing (and availability) are not known. As for the range-topping Grand Cherokee SRT (no longer called the SRT8), this added performance could run you an extra $2,700 with a new starting price of $62,995. More importantly, loaded to the gills with all available options, the 2014 Grand Cherokee SRT will top out at around $72,400 - or around $6,000 more than a fully loaded 2013 GC SRT8.
We'll let you know if the gang over at Jeep get back to us with any confirmation, but until then, head over to Jeep Garage to see the pricing details it has listed.

Jeep Wrangler likely to get aluminum body, will stay in Toledo

Perhaps more than any other vehicle currently for sale in the United States, the Jeep Wrangler is viewed by purist fans as a vehicle that simply must maintain the status quo. In this case, that means a body-on-frame design, solid axles, a relatively large engine sitting up front and a removable top. It's always been that way, and it always will be.
Maybe.
According to the most recent reports, the next-generation Jeep will continue to soldier forth with a full steel chassis underneath its stamped bodywork. The biggest change, reports Automotive News, will be that said panels will be hewn from aluminum instead of steel, a seismic shift of a transition not unlike what's happened with the new Ford F-150. Because it won't be a unibody, the SUV will likely continue to be assembled in Toledo, OH as it (almost) always has been - the latter has been a source of heartburn in recent weeks for the Northwestern city in the Buckeye State.
