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


Soon after a long time of rumored enhancement, Stellantis has discovered its new 6-cylinder motor household. The 3.-liter, twin-turbocharged “Hurricane” I6 will give V8 electrical power, pressured induction torque and six-cylinder effectiveness in a deal developed to in shape into any of the company’s North American rear-wheel-drive platforms. 

What is “V8 electric power,” particularly? Nicely, in typical output guise, the new I6 cranks out far more than 400 horsepower (the distinct determine will fluctuate by software) and 450 pound-feet of torque, though the substantial-output variant is good for much more than 500 horses and 475 lb-ft. The final figures will be dependent on the software. We are going to conserve you a minor legwork: In recent Ram, Jeep and Dodge goods, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or choose, and the 6.4-liter around 485 hp and 475 lb-ft. 


This is a clear-sheet style that is only similar to the firm’s turbocharged 4-cylinder by some common measurements. The I6 is exclusively immediate-injection (no hybrid/port-injection below) and the two I6 variants share 96 typical parts, including the block and oil pan layout. The dissimilarities are found in their internals, consumption plumbing, valvetrain parts and the turbochargers themselves. Stellantis is not however ready to share specs or provider information for the turbos but claims bulletins will arrive from its associates shortly. 

The common-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will operate on frequent fuel, albeit with lessened general performance 91 octane is recommended for greatest output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one particular will involve premium.

The new I6’s rewards go over and above basic power output. Just about every Hemi relatives motor at the moment in manufacturing is based on an iron block design and style, so they are hefty. The aluminum-block I6 shaves bodyweight off the total motor bundle, even if some of that gets additional back thanks to the turbos and their associated plumbing. The common-output I6 weighs 430 kilos, Stellantis engineers informed us the superior-output adds just another 11. Thoroughly dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters shut in on 600 lbs .. 

You might be pondering, “Why a clean up-sheet gasoline engine now, when the business is going towards battery-electrics?” A valid inquiry, and one Stellantis was ready to deal with. While the enterprise will be pivoting to electrification about the next decade, it will never be instantaneous. This engine spouse and children was engineered with electrification (hybrid or plug-in) in thoughts, however Stellantis wouldn’t say when we’ll see all those hybrids. Think of this as a bridge involving ICE and BEV.

In point, the firm’s propulsion team stayed exceptionally restricted-lipped about what to anticipate in terms of apps. In sensible terms, it will healthy any where the 3.6L Pentastar V6 or Hemi fits, delivered you happen to be talking about RWD platforms. For all those who want to do their own measuring, the common 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 reported, will not assume Stellantis to begin chucking the 3.6-liter in favor of the 3.0TT in its mainstream autos. Just since it can fit isn’t going to mean Stellantis will do it search how prolonged it took us to get a Hemi in a Jeep Wrangler. And you should not assume it to pop up in any Stellantis products designed abroad, both. This motor family was built largely for North The us only American-crafted export styles will be in the functioning for the time getting. 

We would not have to hold out extended to find out just wherever it will seem. Stellantis ultimately confirmed rumors that the engine has been in output since November and claims the 1st solutions to make use of it will materialize inside a matter of months, not years. We’re supposed to see the to start with one particular — a Jeep, and the clever revenue is on the new very long-wheelbase Wagoneer — at the New York International Car Display in April.
