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.

Video charts evolution of Jeep from military vehicle to SUV powerhouse

Here's a fun new video from our car-obsessed friends at Donut Media. It shows the evolution of the iconic Jeep from its World War II roots to the forthcoming 2019 Scrambler pickup in a little over two minutes. Using illustrations and audio of Jeep engines and broadcast advertising spots, it's a fascinating look at the common traits that have persisted over more than 75 years and changing consumer preferences. Three companies originally responded to the U.S. Army's request in 1940 for proposals to make a quarter-ton "light reconnaissance vehicle" tailored to its specs — Bantam, Ford and Willys. The video starts by showing all three early contenders — the Bantam Reconnaissance Car, Ford Pygmy and Willys MB, which was based on the Willys-Overland "Quad" prototype, named for the 4x4 system it utilized. Willys eventually won the contract in 1941 to build 16,000 revised MB models for American and Allied forces. Willys would trademark the Jeep name in 1945 with its CJ-2A, a Civilian Jeep geared toward farmers. As the video shows, Jeep really started to diversify its body styles and colors in the 1970s and '80s under the ownership of American Motors Corp., which purchased the money-losing Jeep brand in 1970 from Kaiser-Jeep, which itself had acquired the brand from Willys in 1953. The '70s brought models like the CJ-5 Renegade and CJ-5 Laredo, and the video includes updates including the second-generation Wrangler Unlimited in 2004 and the Wrangler-based Scrambler pickup. Chrysler purchased Jeep from American Motors in 1987, shortly after the debut of the Jeep Wrangler, and has managed to hold onto the brand and ride it to success despite its own bumpy ownership trials and tribulations since then. Despite the many owners over time, Jeep has maintained its headquarters all along in Toledo, Ohio.

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."
