Jeep reveals annual Moab Easter Jeep Safari concepts

Jeep has unveiled its annual spate of concepts before the Easter Jeep Safari. Those start with the Grand Cherokee Trailhawk Concept (below left), complete with the company's EcoDiesel V6 engine. Designers threw in a set of 35-inch Mickey Thompson tires wrapped around 17-inch Rubicon wheels, and a set of custom fender flares help keep all that rubber under wraps.
Meanwhile, the Wrangler Mopar Recon (below right) packs a 6.4-liter Hemi V8 good for 470 horsepower. All that grunt gets to the ground via a five-speed automatic transmission and a set of a Dana 60 axles frond and rear with 4.10 gears. The Recon also makes use of a 4.5-inch prototype long-arm kit and a set of prototype eight-lug bead lock wheels.
The Wrangler Stitch (below left) builds on the momentum of the Wrangler Pork Chop Concept. Engineers once again set out to strike as much weight as possible from the vehicle, and actually managed to trim the curb weight down to 3,000 pounds. That effort has given the machine the same power to weight ratio as the Grand Cherokee SRT8. Plenty of carbon fiber, door deletes and a chrome moly roll cage all help trim those pounds, and a set of DanyTrac Pro Rock 44 axles with 4.88 gears and ARB lockers front and rear let this machine scramble over whatever is in its path.

Jeep mulling power top for next Wrangler

Jeep is hard at work on the next-generation Wrangler, though the truck is still a few years from hitting the trails. The new model will still be aimed at off-roaders, but rumors suggest it will be a little more comfortable than previous versions to appeal to more people.
According to Road and Track, Jeep is developing a power-retractable top as an expensive option for the Wrangler. There is no word if the top in question is a sliding canvas rollback like the ones found on many European vehicles or a full convertible hardtop or softtop, nor do we know whether it would be made available on two- or four-door models. It might be a nice feature for some buyers but would certainly add complexity to a truck already known for its ruggedness. We asked Jeep for confirmation, but Jeep spokesperson Todd Goyer could only remind us that the company "can't comment about future products."
In news that is likely to irk the faithful, R&T reports the next model may also ditch its folding windshield for improved safety and possibly even get rid of its rear-mounted, full-size spare tire. The new Wrangler won't go completely soft, though, and will reportedly still feature removable doors and solid axles.

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.
