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

After several years of rumored advancement, Stellantis has revealed its new 6-cylinder motor relatives. The 3.-liter, twin-turbocharged “Hurricane” I6 will provide V8 ability, compelled induction torque and six-cylinder performance in a bundle created to suit into any of the company’s North American rear-wheel-generate platforms. 

What is “V8 electrical power,” just? Nicely, in conventional output guise, the new I6 cranks out a lot more than 400 horsepower (the distinct determine will change by software) and 450 pound-ft of torque, while the substantial-output variant is excellent for more than 500 horses and 475 lb-ft. The ultimate figures will be dependent on the software. We will preserve you a minimal legwork: In present-day 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 around 485 hp and 475 lb-ft. 


This is a clear-sheet style and design that is only relevant to the company’s turbocharged 4-cylinder by some popular measurements. The I6 is completely immediate-injection (no hybrid/port-injection below) and the two I6 variants share 96 typical areas, which includes the block and oil pan style. The variations are uncovered in their internals, ingestion plumbing, valvetrain factors and the turbochargers them selves. Stellantis is not still all set to share specs or provider facts for the turbos but states announcements will come from its associates shortly. 

The normal-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will operate on frequent gasoline, albeit with diminished functionality 91 octane is encouraged for utmost output. The higher-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That 1 will have to have quality.

The new I6’s advantages go past essential energy output. Each Hemi relatives engine currently in production is based on an iron block style, so they are large. The aluminum-block I6 shaves body weight off the whole engine deal, even if some of that gets extra again thanks to the turbos and their related plumbing. The typical-output I6 weighs 430 kilos, Stellantis engineers explained to us the superior-output provides just yet another 11. Absolutely dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters near in on 600 kilos. 

You may be thinking, “Why a cleanse-sheet gasoline motor now, when the field is shifting towards battery-electrics?” A valid inquiry, and one particular Stellantis was well prepared to address. Even though the corporation will be pivoting to electrification around the future ten years, it will not be instantaneous. This motor family members was engineered with electrification (hybrid or plug-in) in thoughts, nevertheless Stellantis would not say when we are going to see these hybrids. Feel of this as a bridge involving ICE and BEV.

In fact, the company’s propulsion workforce stayed incredibly restricted-lipped about what to assume in conditions of programs. In functional terms, it will in shape wherever the 3.6L Pentastar V6 or Hemi suits, presented you’re talking about RWD platforms. For individuals who want to do their possess measuring, the common output Hurricane actions 33.4 inches x 28.7 inches x 32.7 inches. The superior-output checks in at 33.9″ x 29.” x 33.4″.

That mentioned, never anticipate Stellantis to start out chucking the 3.6-liter in favor of the 3.0TT in its mainstream automobiles. Just due to the fact it can healthy will not imply Stellantis will do it look how prolonged it took us to get a Hemi in a Jeep Wrangler. And do not be expecting it to pop up in any Stellantis products and solutions designed abroad, either. This engine family was built generally for North America only American-constructed export products will be in the managing for the time getting. 

We will never have to hold out prolonged to uncover out exactly where by it will appear. Stellantis ultimately verified rumors that the motor has been in creation considering the fact that November and states the very first merchandise to use it will materialize inside of a matter of months, not a long time. We are intended to see the 1st one particular — a Jeep, and the good funds is on the new extended-wheelbase Wagoneer — at the New York International Vehicle Clearly show in April.
