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.

Cummins builds 2-millionth diesel for Ram

Ahead of a new Ram Heavy Duty that will debut sometime next year (check out the spy shots below), Chrysler and Cummins are celebrating a milestone in a 24-year partnership that has supplied the Ram pickup with diesel engines.
In its early years, the Cummins straight-six turbo diesel was rated at just 160 horsepower and 400 pound-feet of torque, and its clattering 12 valves could be heard from a mile away. Its most recent configuration still uses a straight-six layout, but displacement grew to 6.7 liters in 2007 allowing the engine to now produce up to 385 hp and a whopping 850 lb-ft of torque. While a rumored smaller Cummins engine for use in the light-duty Ram 1500 never materialized, the work-ready 6.7-liter Cummins turbo diesel accounts for 80 percent of all Ram HD sales.
Chrysler has not yet announced when and where this two-millionth engine will be on display, but you can read more about the engine and the partnership in the press release below.

444,000 Cummins diesel Ram trucks recalled for water-pump fire risk

NHTSA recently acknowledged a recall for nearly 444,000 Ram 2500, 3500, 4500 and 5500 trucks built between 2013 and 2017 with Cummins 6.7-liter diesel engines. The issue is that the water pump might do the exact opposite of keeping the engine cool. According to documents from Fiat-Chrysler and NHTSA, Concentric-brand water pumps without vent holes could suffer bearing failure, as well as start leaking coolant. This exposes coolant to hot parts of the engine, and the pump itself can become a hot part. Not all Cummins-equipped Ram trucks will be affected. If your Ram has a water pump from a different brand, or it uses a Concentric pump with some kind of vent holes, you shouldn't have any issues. In fact, the fix will be to replace the non-vented pump with a vented version. Owners with affected vehicles will be able to bring their trucks into a Chrysler dealer, where the water pump will be replaced at no charge. FCA will begin notifying owners of the issue starting on Nov. 1. Owners can also get in touch with Chrysler's customer service department at 1-800-853-1403 and should ask about recall "T51."
