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.

Dodge Dart getting hatchback variant... sort of

In other parts of the world, Fiat builds and sells a version of the Dodge Dart called the Viaggio, and it appears that in addition to the current sedan bodystyle, a new hatchback version of the car is also in the works. Autocar says that the general manager for China's Guangzhou-Fiat joint venture, John Burton, has confirmed that a new Viaggio hatchback will be revealed by the end of this year before it goes on sale in early 2014.
The Viaggio will soon be joined by the 2014 Jeep Cherokee, which in China will be called the Liberty Light, at the Guangzhou-Fiat plant. While the idea of a Dodge Dart hatchback might be enough to enable most of us to forget about the Dodge Caliber, a North American variant doesn't appear to be in the cards. We reached out to Chrysler PR boss Rick Deneau, and he offered a succinct: "No plans at this time."

Dodge Grand Caravan, Journey no longer available in the California emissions states

The Dodge Grand Caravan and the Dodge Journey are no longer available for sale in California or any of the states that follow its emissions standards (often referred to as the ZEV states). As reported by Allpar.com, the 3.6-liter Pentastar V6 in the Grand Caravan does not meet those emissions standards for 2020, and evidently neither does the 2.4-liter four-cylinder that is the sole engine offering in the Journey this year. The Pentastar V6 used in other Dodges, Chryslers and Jeeps is an updated unit that does not face the same emissions issues. The 2020 model year already was due to be the last for the Grand Caravan, which is being replaced in the lineup by a lower-priced and lower-spec version of the Chrysler Pacifica called the Chrysler Voyager. Production of the Grand Caravan at FCA's Windsor, Ontario factory is reportedly due to end in May. As for the Journey, that model has exceeded its sell-by date and is the oldest entrant in its class. The vehicle was introduced as a 2009 model, and not has seen major revisions in the 11 years since. For 2020, Dodge has cut the Journey model lineup to just two trim levels: SE Value and Crossroad (dropping the SE and the GT), and it's front-wheel drive only. But the Journey could continue — in some states at least — into the 2021 model year. Rumors of its replacement, with a sportier model based on the Alfa Romeo Stelvio, don't have it arriving until 2022 or so.
