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.

FCA and ZF issue recall on nine-speed automatic transmission

After years of complaints, German transmission manufacturer ZF is finally issuing a recall of its much maligned 9HP nine-speed automatic transmission. Although it has been criticized for a number of issues, ZF is issuing the recall to address the possibility of the transmission unexpectedly shifting into neutral. The issue covers 505,000 vehicles in the United States alone. This issue is related to an improper crimp on the transmission wiring harness. Rather than a physical fix, ZF is issuing a software update to remedy the problem. The company doesn't recommend dealers attempt to fix the crimp. Although the transmission can be found in a number of models by various manufacturers, currently only those from FCA are being recalled. This is the second recall in less than a year related to a ZF transmission shifting into neutral. FCA recently recalled more than a million vehicles worldwide because of a poorly designed shifter for ZF's 8HP eight-speed automatic. That issue may have resulted in the death of actor Anton Yelchin in June. Although there are no deaths related to this new recall, NHTSA reports that the issue has resulted in at least 10 injuries. Issues with the transmission have been known for years. A number of software updates have attempted to address various problems, making us wonder if there could be a fundamental hardware issue as the complaints span across a number of automakers. Vehicles equipped with the 9HP include 2014 and newer versions of the V6 Acura TLX, Chrysler 200, Fiat 500X, upper-level Honda Pilots, Jeep Cherokee and Renegade, Land Rover Discovery Sport and Range Rover Evoque, and Ram ProMaster City. Only FCA is issuing a recall and only on 2014 and 2015 models. Related Video: News Source: NHTSA Recalls Chrysler Fiat Jeep Safety FCA nine-speed transmission

Detroit Three automakers and UAW will continue to require masks

GM CEO Mary Barra at a Warren, Mich., training center in September. (Reuters)   WASHINGTON — Detroit's Big Three automakers and the United Auto Workers (UAW) union said on Wednesday that workers will continue to be required to wear masks in workplaces. The joint statement from the UAW and General Motors, Ford and Chrysler-parent Stellantis NV said it was continuing the requirements "out of an abundance of caution." The U.S. Centers for Disease Control and Prevention (CDC) said in May that fully vaccinated people do not need to wear masks in most instances, including at work. The UAW and the automakers said temperature screening upon entering facilities is expected to be phased out. The UAW and automakers continue to recommend autoworkers get vaccinated. Many U.S. employers are still requiring vaccinated workers to wear masks in workplaces. Volkswagen AG's U.S. unit said it will "no longer require masks for fully vaccinated employees after June 21, and will continue to follow CDC guidelines." Toyota is among the automakers that has ended temperature checks and entry questionnaires at U.S. plants but it is continuing to require facial coverings. Honda and Nissan said they had made no changes to their U.S. employee COVID-19 requirements.   Plants/Manufacturing Chrysler Dodge Ford GM Jeep RAM Safety coronavirus
