Watch a Jeep CJ get disassembled and reassembled in minutes

Movie buffs! Remember the scene in the James Bond film 007: The Living Daylights where Timothy Dalton's character slices the floorpan off a police Lada using a laser, and when the driver hits the brakes the Lada's body simply jumps off its axles? That scene was immediately brought to mind as I watched this clip of eight Canadian mechanics disassembling a slightly modified Jeep in a matter of seconds. Having driven the Jeep to a complete stop, the technicians start unbolting it until the body lifts off the frame and the engine can be hauled away. It only took half a minute to turn the Jeep into just a chassis on wheels. As repair manuals say, refitting is the reversal of removal. Apparently the technicians have now honed their mechanical choreography to the point that the Jeep can be disassembled and reassembled in two minutes and 39 seconds; while I expect a great number of bolts having been removed beforehand and the likelihood of the Jeep falling to pieces with a sharp braking being significant, it is definitely impressive. It also reminds me of someone driving an old, dodgy car, having learned all its kinks to be able to keep it running. According to a Reddit thread, the pre-modified "Jifty Jeep" has been built (and taken apart, and rebuilt) by the School of Royal Canadian Electrical and Mechanical Engineers (RCEME) for exactly this purpose. The team travels all around Canada to practice their show, trying to shave seconds off their record. There are worse hobbies.

Fiat Chrysler recalls 4.8 million U.S. vehicles for cruise control defect

WASHINGTON - Fiat Chrysler said on Friday it is recalling 4.8 million U.S. vehicles over a defect that could prevent drivers from deactivating cruise control and warned owners not to use the function until they get software upgrades. The Italian-American automaker said no injuries or crashes are related to the large recall campaign but said it had one report of a driver of a 2017 Dodge Journey rental car unable to deactivate the cruise control. Fiat Chrysler, which in 2015 was hit with penalties from U.S. regulators totaling $175 million for safety lapses, did not say how much the recalls would cost. The recall addresses what Fiat Chrysler called an "extremely rare" series of events that could lead to drivers being unable to cancel cruise control. The National Highway Traffic Safety Administration (NHTSA) said on Friday it "strongly encourages vehicle owners to follow a warning" to stop using cruise control on the recalled vehicles until repaired. NHTSA said drivers could overpower the system by forcefully applying the brakes until the vehicle stopped. Fiat Chrysler also said the vehicle could be stopped by shifting into neutral and braking. Fiat Chrysler shares fell more than 2 percent in premarket trading in New York on the recall. Fiat Chrysler noted that at times cruise control systems automatically initiate acceleration to help vehicles maintain driver-selected speeds, including when going up an incline. If an acceleration occurs simultaneously with a short-circuit in a specific electrical network, a driver could be unable to deactivate the function. Fiat Chrysler said vehicles may be placed in park once stopped, at which point cruise-control is canceled. The recall involves a group of gasoline-powered vehicles with automatic transmissions from various model years built from 2014 through the 2019 model year. Most of the vehicles being recalled cover the 2014-2018 model years. Among the vehicles being recalled are the Chrysler 200, Chrysler 300, Chrysler Pacifica, Dodge Charger, Dodge Challenger, Dodge Journey, Dodge Durango, Jeep Cherokee, Jeep Grand Cherokee, Jeep Wrangler and Ram 1500, 2500 and 3500 pickup trucks and Ram 3500/4500/5500 cab chassis trucks. Fiat Chrysler made the announcement going into the busy Memorial Day weekend, which traditionally kicks off the summer driving season.

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.
