After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged “Hurricane” I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company’s North American rear-wheel-drive platforms.
What is “V8 power,” exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We’ll save you a little legwork: In current Ram, Jeep
This is a clean-sheet design that is only related to the company’s turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid
The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium.
The new I6’s advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they’re heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430
You may be wondering, “Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?” A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won’t be instantaneous. This engine family was engineered with electrification (hybrid or plug-in) in mind, however Stellantis wouldn’t say when we’ll see those hybrids. Think of this as a bridge between ICE and BEV.
In fact, the company’s propulsion team stayed incredibly tight-lipped about what to expect in terms of applications. In practical terms, it will fit anywhere the 3.6L Pentastar V6 or Hemi fits, provided you’re talking about RWD platforms. For those who want to do their own measuring, the standard output Hurricane measures 33.4 inches x 28.7 inches x 32.7 inches. The high-output checks in at 33.9″ x 29.0″ x 33.4″.
That said, don’t expect Stellantis to start chucking the 3.6-liter in favor of the 3.0TT in its mainstream cars. Just because it can fit doesn’t mean Stellantis will do it; look how long it took us to get a Hemi in a Jeep Wrangler. And don’t expect it to pop up in any Stellantis products built overseas, either. This engine family was designed primarily for North America; only American-built export models will be in the running for the time being.
We won’t have to wait long to find out exactly where it will appear. Stellantis finally confirmed rumors that the engine has been in production since November and says the first products to utilize it will materialize within a matter of months, not years. We’re supposed to see the first one — a Jeep, and the smart money is on the new long-wheelbase Wagoneer
