The outdated AMC inline-6 was known as Tornado. This one is known as Hurricane as a result of, , a hurricane is yet another than a twister, or one thing.

Developing a brand new engine from the bottom up is an especially intricate and costly job, however counting on outdated designs for brand spanking new engines can solely take effectivity to date. Sometimes, going again to the drafting board can produce one thing that is much better tailor-made for the wants of at this time. That’s a part of the explanation why Stellantis went to all of the work to create a completely new inline-6 gasoline engine.
Say hiya to the Hurricane. Built partially to assist section out bigger engines as Stellantis strives for growing effectivity, the Hurricane is alleged to supply V8 efficiency at a two-cylinder discount. When it involves market, this dual-overhead-cam engine shall be provided in each environment friendly standard-output (SO) kind, in addition to a performance-oriented high-output (HO) variant.
The two engines share 96 widespread components, together with the block, exhaust camshaft and spark plugs, however every variant has dozens of distinctive items meant to get probably the most out of what every variant gives. That stated, the extra environment friendly model will not precisely be a slouch, as Stellantis claims it will be able to placing out greater than 400 horsepower and 450 pound-feet of torque. The high-output Hurricane, however, will be capable of ship upwards of 500 horsepower and 475 lb-ft. Both ought to have a pleasant, flat torque curve that dials up practically all its accessible twist by 2,350 rpm.
The high-output Hurricane appears only a bit beefier than the standard-output Hurricane proven above.

On the facet of the Hurricane rests two small turbochargers, which Stellantis selected over a single, bigger turbocharger as a way to ship increase quicker and at decrease engine revs. The SO and HO variants will every put on distinctive turbochargers, with the SO’s snails topping out at 22 psi, whereas the HO’s compressors provide a bit extra squeeze at 26 psi.
The two Hurricanes share some 96 completely different components, together with the block, exhaust camshaft and coolant pumps. But there are profound variations between the 2 nonetheless. The Hurricane SO will depend on forged aluminum pistons and a ten.4:1 compression ratio; common unleaded will suffice right here, however Stellantis recommends premium for a small output increase. The Hurricane HO, however, makes use of solid aluminum pistons with a 9.5:1 compression ratio. That one will solely suck up 91 octane and above.

For these of you sitting right here questioning the place the electrical energy is available in, don’t be concerned, it would doubtless occur. While Stellantis did not launch the Hurricane with any electrified variants on provide, the automaker guarantees that the engine was construct with electrification in thoughts. Whether that alludes to a light hybrid or a plug-in hybrid stays a secret, however primarily based on Stellantis’ work within the PHEV area over the previous few years, it isn’t obscene to imagine the Hurricane might find yourself as a part of a plug-in resolution.
Right now, it is also nonetheless unclear precisely which automobiles will make the most of the Hurricane, however we have now some concepts. The first automobiles with this tech underneath the hood will arrive at dealerships this 12 months, so it would doubtless land in a 2022 or 2023 variant. Stellantis did say that this may grow to be the engine of selection for future US vehicles on the STLA Large and STLA Frame international platforms. That would make it a major alternative for the 5.7-liter Hemi V8 in, say, a future Ram 1500 or Jeep Wagoneer, however once more, we’ll have to attend till Stellantis offers us extra info earlier than any of that’s confirmed.
