Stellantis unveils the Hurricane, a 3.0-liter turbocharged inline-6 ​​with clean sheet


Developing a new engine from scratch is an extremely complex and expensive task, but relying on old designs for new engines can only take efficiency so far. Sometimes going back to the drawing board can produce something that’s much better suited to today’s needs. That’s part of the reason Stellantis has done all the hard work to create an all-new inline-6 ​​gas engine.

Say hello to the hurricane. Built in part to help phase out larger engines as Stellantis strives to increase efficiency, the Hurricane is supposed to offer V8 performance at a great price for both cylinders. As for the market, this DOHC engine will be offered in both efficient Standard Output (SO) form, as well as a performance-oriented High Output (HO) variant.

Both engines share 96 common parts, including the block, exhaust camshaft and spark plugs, but each variant features dozens of unique parts meant to make the most of what each variant offers. That said, the more efficient version won’t exactly be outdone, as Stellantis claims it’ll be capable of producing over 400 horsepower and 450 pound-feet of torque. The high-output Hurricane, meanwhile, will be able to deliver over 500 horsepower and 475 lb-ft. Both should have a nice flat torque curve that boosts almost all of its available torque by 2,350 rpm.

The High Yield Hurricane just looks a bit beefier than the Standard Yield Hurricane pictured above.


On the side of the Hurricane are two small turbochargers, which Stellantis chose rather than a single larger turbocharger to provide faster boost and at lower engine speeds. The SO and HO variants will each sport unique turbochargers, with the SO snailing out at 22 psi, while the HO’s superchargers offer a bit more compression at 26 psi.

The two Hurricanes share some 96 different parts, including the block, exhaust camshaft and coolant pumps. But there is deep differences between the two again. The Hurricane SO will rely on cast aluminum pistons and a compression ratio of 10.4:1; Regular unleaded will suffice here, but Stellantis recommends premium for a small boost in production. The Hurricane HO, on the other hand, uses forged aluminum pistons with a compression ratio of 9.5:1. This one will only suck 91 octane and above.

For those of you sitting here wondering where the electricity is coming from, don’t worry, it will probably happen. While Stellantis hasn’t launched the Hurricane with electrified variants on offer, the automaker promises the engine was built with electrification in mind. Whether this hints at a mild hybrid or a plug-in hybrid remains a secret, but based on Stellantis’ work in the PHEV space over the past few years, it’s not obscene to assume the hurricane might end. as part of a Solution plug-in.

At this time, it’s still unclear exactly which vehicles will use the Hurricane, but we have a few ideas. The first vehicles with this tech under the hood will hit dealerships this year, so they’ll likely land in a 2022 or 2023 variant. Stellantis said it will become the engine of choice for future US cars on global STLA platforms. Wide and STLA Frame. That would make it a prime replacement for the 5.7-liter Hemi V8 in, say, a future Ram 1500 or Jeep Wagoneer, but again, we’ll have to wait for Stellantis to give us more information before that’s all over. confirmed.
