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.

The Ram Macho Power Wagon concept is totally in your face with its cool rack system

The Ram brand isn't being very subtle with this year's SEMA concept. It's called the Macho Power Wagon, and it's painted in Macho Mango. Yeah, it's for dudes. We apologize if you start hearing a Village People song in the back of your head. This bigger, badder Ram is a throwback to the Macho Power Wagon of the late 1970s. Along those lines, it bears the retro, vertical Power Wagon graphics that line the C-pillar, and it also has vintage-style eight-spoke beadlock wheels inspired by its '70s namesake. Those wheels are shod in huge 37-inch tires, which fit thanks to a four-inch suspension lift, and custom, conceptual fender flares. View 20 Photos The truck is powered by the normal Power Wagon's 6.4-liter V8, rather than the crazy TRX concept's supercharged Hemi, and it has the stock front winch. This Ram also sports quite a few concept parts besides the wheels and fender flares. Starting at the front and moving rearward, the Macho Wagon gets custom bumpers with skid plates and tow hooks, a new hood with big heat extractors, an LED light bar, a roof rack, single-piece running-boards, and five-inch exhaust tips. There's one more custom piece in back. Immediately behind the C-pillar is a sport hoop, under which hides another hoop that can slide along tracks on the bed. These hoops together are called the Ramrack, and when the second hoop is moved back along the bed, it works together with the cab's roof rack to create a long utility rack. It's a thoroughly clever way of adding practicality without sacrificing appearances. We would love to see something like this reach production, since it could be very handy on quad cab pickups with short beds, allowing them to carry long objects without having to drop the tailgate to get them to fit. Because there's nothing macho about that. Related Video:

Fiat Chrysler, Waymo expand partnership for Level 4 self-driving

Fiat Chrysler and Waymo, the self-driving unit of Google parent Alphabet Co., are expanding their partnership in an ambitious plan to develop fully autonomous commercial delivery vehicles and integrate Level 4 autonomous technology across the FCA fleet, the two companies said Wednesday. The agreement makes FCA (soon to be dubbed Stellantis when the PSA merger is complete) the exclusive partner for Waymo to develop and test self-driving Class 1-3 light commercial delivery vehicles. Initial efforts will focus on integrating the Waymo Driver system into the Ram ProMaster cargo van for commercial fleets, including Waymo Via, which have seen demand for home delivery services mushroom during the coronavirus pandemic. Conversely, FCA has tapped Waymo as its exclusive supplier for Level 4 self-driving technology across its vehicle fleet, opening up possibilities for ride-hailing and personal-use vehicles. An FCA spokesman would not commit to any timelines for integrating Waymo’s self-driving technology into the ProMaster or other brands or models. The Society of Automotive Engineers defines Level 4 systems as fully automated driving, though a human driver can manually override and take control of the wheel. There are currently no Level 4 autonomous vehicles offered to customers, and most experts believe the technology still faces many obstacles to broad adoption and regulatory clearance. Fiat Chrysler first partnered with Waymo in 2016. The two companies have worked to test WaymoÂ’s Level 4 technology using retrofitted Chrysler Pacifica Hybrid minivans. “Our now four-year partnership with Waymo continues to break new ground,” Mike Manley, Fiat ChryslerÂ’s CEO, said in a statement. “Incorporating the Waymo Driver, the worldÂ’s leading self-driving technology, into our Pacifica minivans, we became the only partnership actually deploying fully autonomous technology in the real world, on public roads.” Waymo recently introduced its fifth generation of the Waymo Driver system, which it completely redesigned to be able to handle more environments and situations. It combines 360-degree lidar sensors positioned atop the vehicle and at four points around the sides, plus cameras and radars. Waymo said it had already manufactured the new sensors and integrated them onto Jaguar I-Pace test vehicles.
