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


Following several years of rumored enhancement, Stellantis has unveiled its new six-cylinder engine spouse and children. The 3.-liter, twin-turbocharged “Hurricane” I6 will give V8 power, compelled induction torque and six-cylinder effectiveness in a package deal created to in shape into any of the firm’s North American rear-wheel-push platforms. 

What is “V8 energy,” exactly? Effectively, in normal output guise, the new I6 cranks out a lot more than 400 horsepower (the distinct determine will change by application) and 450 pound-toes of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The closing figures will be dependent on the software. We will help you save you a minimal legwork: In existing Ram, Jeep and Dodge solutions, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or choose, and the 6.4-liter about 485 hp and 475 lb-ft. 


This is a clean-sheet structure that is only related to the firm’s turbocharged four-cylinder by some frequent measurements. The I6 is completely immediate-injection (no hybrid/port-injection in this article) and the two I6 variants share 96 prevalent components, such as the block and oil pan design and style. The differences are found in their internals, ingestion plumbing, valvetrain components and the turbochargers them selves. Stellantis is not yet ready to share specs or provider details for the turbos but says announcements will appear from its partners before long. 

The common-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on normal fuel, albeit with lessened efficiency 91 octane is proposed for most output. The significant-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That a single will involve premium.

The new I6’s positive aspects go further than standard energy output. Every single Hemi spouse and children motor currently in manufacturing is based on an iron block style and design, so they are hefty. The aluminum-block I6 shaves weight off the whole engine bundle, even if some of that receives added back again many thanks to the turbos and their linked plumbing. The standard-output I6 weighs 430 kilos, Stellantis engineers informed us the higher-output provides just another 11. Completely dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters near in on 600 lbs .. 

You may perhaps be wondering, “Why a thoroughly clean-sheet gasoline engine now, when the field is relocating toward battery-electrics?” A valid inquiry, and a person Stellantis was prepared to handle. Whilst the corporation will be pivoting to electrification above the up coming ten years, it would not be instantaneous. This motor household was engineered with electrification (hybrid or plug-in) in intellect, nevertheless Stellantis wouldn’t say when we are going to see individuals hybrids. Assume of this as a bridge among ICE and BEV.

In actuality, the firm’s propulsion workforce stayed very limited-lipped about what to hope in phrases of purposes. In practical conditions, it will healthy any place the 3.6L Pentastar V6 or Hemi matches, presented you happen to be speaking about RWD platforms. For people who want to do their own measuring, the common output Hurricane actions 33.4 inches x 28.7 inches x 32.7 inches. The higher-output checks in at 33.9″ x 29.” x 33.4″.

That claimed, don’t count on Stellantis to start off chucking the 3.6-liter in favor of the 3.0TT in its mainstream cars and trucks. Just because it can healthy would not mean Stellantis will do it look how extended it took us to get a Hemi in a Jeep Wrangler. And don’t assume it to pop up in any Stellantis solutions designed overseas, both. This motor household was designed principally for North The usa only American-crafted export types will be in the functioning for the time currently being. 

We will never have to hold out very long to uncover out specifically exactly where it will appear. Stellantis eventually confirmed rumors that the motor has been in generation considering that November and states the very first solutions to make use of it will materialize within a issue of months, not several years. We are intended to see the first a single — a Jeep, and the intelligent funds is on the new very long-wheelbase Wagoneer — at the New York Worldwide Auto Show in April.
