500+ hp Stellantis ‘Hurricane’ I6 previews a world without Hemis


Just after yrs of rumored enhancement, Stellantis has uncovered its new six-cylinder engine household. The 3.-liter, twin-turbocharged “Hurricane” I6 will provide V8 ability, forced induction torque and six-cylinder performance in a bundle created to match into any of the firm’s North American rear-wheel-push platforms. 

What is “V8 electric power,” specifically? Well, in common output guise, the new I6 cranks out much more than 400 horsepower (the unique determine will vary by application) and 450 pound-toes of torque, although the substantial-output variant is great for a lot more than 500 horses and 475 lb-ft. The final figures will be dependent on the software. We will save you a minimal legwork: In latest Ram, Jeep and Dodge products and solutions, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or acquire, and the 6.4-liter all-around 485 hp and 475 lb-ft. 

 

This is a thoroughly clean-sheet design and style that is only relevant to the company’s turbocharged 4-cylinder by some typical measurements. The I6 is solely immediate-injection (no hybrid/port-injection listed here) and the two I6 variants share 96 typical components, such as the block and oil pan layout. The variations are located in their internals, ingestion plumbing, valvetrain factors and the turbochargers them selves. Stellantis is not nevertheless ready to share specs or provider info for the turbos but says bulletins will occur from its companions quickly. 

The normal-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will operate on standard gasoline, albeit with minimized functionality 91 octane is encouraged for most output. The large-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That 1 will call for premium.

The new I6’s pros go beyond standard ability output. Just about every Hemi family motor presently in manufacturing is based mostly on an iron block style and design, so they are significant. The aluminum-block I6 shaves excess weight off the complete motor offer, even if some of that receives additional again thanks to the turbos and their associated plumbing. The regular-output I6 weighs 430 kilos, Stellantis engineers informed us the higher-output adds just an additional 11. Thoroughly dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters shut in on 600 lbs. 

You may perhaps be wanting to know, “Why a clean-sheet gasoline motor now, when the business is moving toward battery-electrics?” A legitimate inquiry, and a person Stellantis was well prepared to tackle. Even though the company will be pivoting to electrification above the future ten years, it will never be instantaneous. This engine spouse and children was engineered with electrification (hybrid or plug-in) in mind, nonetheless Stellantis would not say when we are going to see those hybrids. Assume of this as a bridge involving ICE and BEV.

In simple fact, the firm’s propulsion workforce stayed exceptionally restricted-lipped about what to be expecting in conditions of programs. In useful phrases, it will healthy anywhere the 3.6L Pentastar V6 or Hemi fits, presented you are chatting about RWD platforms. For these who want to do their have measuring, the normal output Hurricane measures 33.4 inches x 28.7 inches x 32.7 inches. The high-output checks in at 33.9″ x 29.” x 33.4″.

That stated, don’t count on Stellantis to start out chucking the 3.6-liter in favor of the 3.0TT in its mainstream vehicles. Just due to the fact it can in shape would not mean Stellantis will do it glimpse how long it took us to get a Hemi in a Jeep Wrangler. And really don’t be expecting it to pop up in any Stellantis products and solutions constructed abroad, possibly. This engine family members was built mostly for North America only American-crafted export types will be in the operating for the time being. 

We will not have to wait lengthy to obtain out accurately exactly where it will surface. Stellantis ultimately verified rumors that the motor has been in creation considering that November and claims the very first merchandise to employ it will materialize inside of a make any difference of months, not several years. We’re meant to see the 1st just one — a Jeep, and the intelligent funds is on the new prolonged-wheelbase Wagoneer — at the New York Global Vehicle Present in April.
