Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.

We test the latest Easter Jeep Safari off roaders in Moab

The Easter Jeep Safari began as a play for tourism: in 1967 the Moab Chamber of Commerce invited "the Jeeping community" to ride a single trail on the Saturday before Easter. The attendees were mostly members and friends of the Chamber of Commerce. Now, 52 years later, the nine-day Safari takes place on more than 40 trails and lures thousands of Jeepers, who put on one of the biggest and best modified Jeep shows in the world. Cue the designers at Jeep and Mopar, who mastermind new ideas every year for what a modified Jeep could look like, with inspiration from the experiences they have and the mods they see at the Safari. We flew to Moab to drive the seven newest concepts, and start the recap with the disappointments: The B-Ute and the 4-Speed, but only because we couldn't drive them. Before the day had properly begun, those two designer treats had tapped out. The Renegade – internally codenamed B Utility, hence the "B-Ute" name – always feels like The Little Engine that Could when placed next to its halo Wrangler brother. In addition to the cosmetic changes, designers put the arcane caption "Lt. Jenkins" above "FWD1337" (explanations of those two memes here and here). The B-Ute would have been nice to drive if for no other reason than shouting "Leeeroy Jenkins" all around the course. View 16 Photos We rued missing out on the 4-Speed. The blue wonder is the third of a conceptual trio called "The Lightweights," focused on nimble trail handling provided by weight savings. The first of the Lightweights, the 2011 Pork Chop concept, cut 900 pounds from a standard Wrangler Sport. The 2013 Stitch concept lopped 1,100 pounds. The 4 Speed omits 900 pounds. Jeep brought both earlier concepts, and they were revelations. The Stitch was a throwback to stripped-out Dukes-of-Hazard-style Jeep romping. Round vents at the edges of the instrument panel act as side mirrors, Fiat Abarth seats grip occupants, the lemon-hued bikini top sewn from a transparent welding curtain bathes the cockpit in yellow light. Daisy Duke drove a 1980 CJ-7 that had 87 horsepower to move 2,700 pounds. The Stitch weighs about 3,200 pounds, but gets 290 hp. The Stitch skimmed over rocks and floated over sand, so light on its feet that Jeep lead designer Mark Allen told us the 35-inch Mickey Thompson MTZ tires were inflated to a mere 3 psi. The 4-Speed concept's pretty close to the Stitch weight thanks to carbon bits and lighter four-cylinder engine.

What's really going on with the 2014 Jeep Cherokee's transmission issues?

On September 23, Automotive News reported that Chrysler had idled the second shift workers it hired just five weeks prior at its Toledo Assembly Complex to build the 2014 Jeep Cherokee. At the time, Chrysler said it had "built the critical number of vehicles we need to stock dealerships once containment is released" and did not want "to put additional strain on our logistics partners ... upon release." That reasoning was not only unusual, it didn't seem to make sense.
It appears the center of the nine-speed issue is software, not hardware.
That same day, the Detroit News ran a piece claiming workers at the Toledo factory said the halt was due to issues with the Cherokee's transmission. It put the number of already-built Cherokees needing fixes at 1,000 and said that some of the workers not laid off had been instructed "to take the Jeep on long test-drives." That made more sense. Three days later, on September 26, Automotive News reported that the 500 workers laid off had been reinstated, with engineers "speeding repairs on the SUV's powertrain software." The AN piece didn't put a number on how many units are being fixed, but it did say that 12,000 have been built and are awaiting delivery to dealers. The best it could say about when dealers will get them, however, is that "progress on a fix is being made. It's unclear when shipments to dealers will start."
