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

After many years rumor development, Stellantis has revealed its new line of six-cylinder engines. The twin-turbocharged 3.0-liter “Hurricane” I6 will deliver V8 power, forced-induced torque and six-cylinder performance in a package designed to fit any rear-wheel drive platform. company in North America.

What is “V8 Power”, exactly? Well, in standard output guise, the new I6 has over 400 horsepower (specific numbers will vary by application) and 450 pound-feet of torque, while the high-power variant is good for over 500 hp and 475 lb-ft. The final figures will depend on the application. We’ll save you a bit of work: In current Ram, Jeep car and Avoid product, the 5.7-liter Hemi topped out with about 395 hp and 410 lb-ft, give or take, and the 6.4-liter with around 485 hp and 475 lb-ft.

This is a clean design that concerns only the company’s turbocharged four-cylinder engine by some conventional measurements. I6 is direct injection exclusively (no mixture/port-injection here) and the two I6 variants share 96 parts in common, including the block design and the oil pan. The difference is found in their internals, plumbing, valve system components, and the turbocharger itself. Stellantis is not yet ready to share specs or supplier information for the turbo engine but says partners will make an announcement soon.

Standard output I6 has a compression ratio of 10.4:first and revs to 5,800 rpm. It will run on conventional fuel, albeit with reduced performance; An octane rating of 91 is recommended for maximum output. The high-power variant has a compression ratio of 9.4:1 and will hit 6,100 rpm. That will require a premium.

The advantages of the new I6 extend beyond basic power output. Every Hemi family motor currently being produced is based on an iron block design, so they are very heavy. The aluminum I6 block reduces the weight of the total engine package, even if some of it is added back in thanks to the turbos and their accompanying plumbing. I6 standard output heavy 430 pound, Stellantis engineers told us; High output adds only 11. The fully-equipped 5.7-liter V8 sits in a 550-560-pound ballpark, and the 6.4-liter is nearly 600 pounds.

You may be wondering, “Why have a clean gasoline engine when the industry is transitioning to battery-electricity?” A valid investigation and a Stellantis have been prepared for settlement. While the company will move towards electrification over the next decade, it won’t happen immediately. These engines are designed with electrification in mind (hybrid or plug-in), but Stellantis won’t say when we’ll see those hybrids. Think of this as a bridge between ICE and BEV.

In fact, the company’s motivation team remains extremely tight-lipped about what to expect in terms of apps. In practical terms, it should fit anywhere that fits a Pentastar V6 3.6L or Hemi, as long as you’re talking about the RWD platform. For those who want to measure themselves, the standard output Hurricane measures 33.4 inches x 28.7 inches x 32.7 inches. High output test at 33.9″ x 29.0″ x 33.4″.

That said, don’t expect Stellantis to start dropping the 3.6-liter engine in favor of the 3.0TT in its entry-level cars. Just for it maybe Matching doesn’t mean Stellantis will do; let’s see how long it took us to get a Hemi in one Jeep Wrangler. And don’t expect it to appear in any Stellantis products made abroad either. This family of engines is designed primarily for North America; Currently, only US-made export car models can be used.

We won’t have to wait long to find out exactly where it will appear. Stellantis finally confirmed Rumor has it that the engine has been in production since November and says the first products using it will be available within months, not years. We have to see the first one – a Jeep and a smart coin in the new long wheelbase Wagoneer – at the New York International Auto Show in April.
