Jeep fans will undoubtedly know the name “Hurricane,” as it was the moniker for the F-head four-banger that propelled early Willys CJs—itself a modification of the original “Go Devil” engine which was found under the hoods of those legendary World War II-era Willys MB and Ford GPW Jeeps.

Well, Stellantis is bringing the Hurricane name back, in the form of a twin-turbocharged 3.0L engine that, the company says, is capable of making over 500 hp when properly configured.

And—get this—the engine is an inline six!

So for all of those folks who lamented the passing of Jeep’s iconic 4.0L straight six, perhaps this new Hurricane will fit the bill.

Details on the New 3.0L Twin-Turbo Hurricane I6

The new Hurricane has been in the works for a while now, but the enthusiast community was eagerly awaiting the engine’s official specs. And they’re impressive. Per the Stellantis release, the engine will come in two basic flavors:

  • Standard Output (SO): Optimized for fuel economy, including the use of cooled exhaust gas circulation (EGR), while delivering enhanced power and torque (more than 400 hp/450 lb.-ft. of torque)
  • High Output (HO): Optimized for great performance (more than 500 hp/475 lb.-ft.) while maintaining significant fuel economy during heavy use, such as towing.

If you’re keeping track at home, those numbers best a lot of turbo V6s and quite a few NA V8s too (including some of the company’s own Hemi engines). Better still, Stellantis says the Hurricane “achieves this V8-rivaling performance while being up to 15% more efficient than larger engines.”

And if you’re wondering where the Hurricane makes its power, there’s more good news. The release says it’s got a “broad, flat torque band that sees the engine maintain at least 90% of peak torque from 2,350 rpm all the way to its red line.”

More 3.0L Hurricane Engine Specs

The Hurricane is an aluminum block engine, and features a pair of turbos—each feeding three cylinders. The Hurricane is direct injected and, depending on the setup, the turbochargers generate from 22 to 26 psi of boost. It’s got dual overhead cams, an aluminum pan, and the HO version gets a forged crank and connecting rods (with cast aluminum pistons).

The High Output version runs 9.5:1 compression and requires 91 octane, the Standard Output engine gets bumped to 10.4:1, and Stellantis says that one needs premium fuel.

Cooling was emphasized on the Hurricane, and the motor has dual water-cooled exhaust manifolds integrated into the cylinder head, and an engine-mounted water-to-air intercooler.

The engine shares a lot of its design with the 2.0 turbo four already available in vehicles like the Jeep Wrangler.

3.0L Hurricane I6 Applications & Availability

We’ve mentioned Jeep a lot already in this article, but it seems like this new powerplant will be equally at home under the hood of a Ram truck or Dodge SUV too. (And wouldn’t it be neat if they could squeeze it into a Challenger?)

We’ll find out soon enough, as Stellantis says we’ll start seeing the Hurricane appear in dealer showrooms by the end of this year.
