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.

MotorWeek reviews '83 American Motors lineup

The 30th anniversary of American Motors' 1987 sale to Chrysler by Renault is just a few years away. AMC is long dead, but for its latest peek in the archives, MotorWeek winds back the clock to somewhat happier times. Take a look at the entire AMC lineup from 1983, including its models from Jeep and Renault. The Jeeps, and to a lesser extent, the AMC Eagle, enjoy a cult following today, but it's amazing how many of these other vehicles are now practically forgotten. Even the big debut in '83 of the Renault Alliance is largely ignored. Although with a ludicrous amount of body roll and a 55-horsepower 1.4-liter engine, it's probably rightly buried.

500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.
