Hurricane engines by vehicle

Output figures as each brand lists them:

In the Ram 1500, both Hurricane inline-sixes pair with a TorqueFlite 8HP75 eight-speed automatic. Dodge also announced a 600-hp 2027 Charger Super Bee Launch Edition as the most powerful SIXPACK Charger.

From What's New for 2027: Ram 1500, What's New for 2025: Jeep Wagoneer, Dodge's SIXPACK-powered 2026 Charger R/T and SIXPACK Powered video series releases, and the 2026 Jeep Grand Cherokee Hurricane 4 Turbo release, all on the Stellantis North America media site, read November 11, 2026.

How the 3.0-liter twin-turbo inline-six works

Dodge's Charger releases describe the hardware behind the two outputs:

• S.O. (Charger R/T): twin 50mm low-inertia turbochargers with counter-rotating turbine assemblies, up to 22 psi of boost and full peak torque by 2,500 rpm.
• Direct fuel injection at 5,075 psi (350 bar) with centrally mounted injectors.
• Oil-jet-cooled cast-aluminum pistons with an anodized top ring and DLC-coated pins (S.O.).
• H.O. (Charger Scat Pack): twin 54mm Garrett GT2054 turbochargers with a peak boost of 30 psi, 88% of peak torque at 2,500 rpm and more than 90% of peak torque from 3,000 to 6,000 rpm.
• H.O. internals: forged pistons, a forged steel crank and a closed-deck aluminum block with PTWA-coated cylinders.

Jeep says the Hurricane Twin Turbo I-6 in the 2025 Wagoneer is up to 15% more efficient than larger V-8 engines.

How the 2.0-liter Hurricane 4 Turbo works

Stellantis lists these features for the Hurricane 4 Turbo:

• 324 hp at 6,000 rpm and 332 lb-ft from 3,000 to 4,500 rpm (SAE-certified), or 162 hp per liter.
• Turbulent jet ignition (TJI): a spark plug lights a small amount of fuel in a pre-chamber atop each cylinder, and the burning fuel jets into the main chamber for a faster, more complete burn. Each cylinder has two spark plugs.
• A variable-geometry turbocharger with up to 35 psi of boost and 90% of peak torque from 2,600 to 5,600 rpm.
• A Miller Cycle strategy and a 12:1 compression ratio on regular (87 octane) gasoline.
• Both port fuel injection and 350-bar (5,076 psi) direct injection.
• PTWA-coated cylinder bores, like the Hurricane Twin Turbo I-6 engines.
• Assembled in Dundee, Michigan.

Stellantis says it uses 10% less fuel to deliver 20% more power than its current 2.0-liter DOHC I-4. In the 2026 Grand Cherokee, Jeep gives an estimated 529-mile driving range on a tank and a 6,200-pound towing figure.
