HURRICANE H/O Makes Wards 10-Best Engines List For 2024

Stellantis’ Hurricane 3.0-liter High Output (H/O) Straight-Six Turbo (SST) engine has earned a prestigious spot on the Wards 10-Best Engines & Propulsion Systems list for 2024. Powering the all-new 2025 Ram 1500, this marks the second time the Hurricane engine has received this accolade, highlighting its status as a top contender in the highly competitive light-duty pickup truck segment.

A Winning Streak for Stellantis – 

This recognition also extends Stellantis’ (formerly FCA) streak to eight consecutive years on the Wards list, showcasing the company’s consistent excellence in propulsion system engineering. Known for its power, efficiency, and advanced technology, the Hurricane SST engine reinforces Stellantis’ position as a leader in the powertrain industry.

“We engineered our Hurricane twin-turbo engines to be powerful, efficient, robust, and versatile, delivering performance that enhances the driving experience both on- and off-road and while towing,” said Micky Bly, Head of Global Propulsion Systems at Stellantis. “The 3.0-liter Hurricane High Output engine, standard in the 2025 Ram 1500 Tungsten, exemplifies our ability to satisfy a range of truck customer needs, offering power, performance, capability, and class-leading NVH in one package.”

Big Power, Big Efficiency –

The 2025 Ram 1500 Tungsten, Limited, Longhorn, and Rebel High Output (RHO) models come equipped with the impressive Hurricane H/O engine, delivering a substantial 540 horsepower and 521 lb.-ft. of torque. This output surpasses traditional naturally aspirated V8s and competing boosted six-cylinder engines in the segment. Paired with the TorqueFlite 8HP75 8-speed automatic transmission, the engine ensures smooth, seamless shifts while optimizing fuel efficiency, drivability, and performance.

Bob Gritzinger, Ward’s editor-in-chief, commended the engine’s capabilities, stating, “The Hurricane High-Output Straight-Six Turbo packs a powerful punch from launch to well past legal speed while also delivering promised fuel economy that represents an improvement over the HEMI® V-8 it replaces. This engine should sway even the most ardent V-8 buyer into the 6-cylinder family.”

A Clean-Sheet Design with Advanced Technology –

As part of Stellantis’ Dare Forward 2030 strategic plan, the Hurricane H/O engine reflects a forward-thinking, clean-sheet design that incorporates cutting-edge technology to strike a balance between power, fuel efficiency, and lower emissions.

Some of the key innovations include:

• Dual low-inertia turbochargers: These turbochargers feed three cylinders each, optimizing airflow and providing rapid throttle response, boosting both performance and efficiency.
• Plasma transfer wire arc coating: Applied to the cylinder bores, this ultra-thin, low-friction coating enhances durability and fuel economy by reducing wear.
• High-pressure direct fuel injection: Operating at 5,075 psi (350 bar), this advanced system delivers precise fuel atomization for better combustion and reduced emissions.
• Water-to-air charge cooler: Mounted directly on the engine with a dedicated cooling circuit, this system ensures consistent performance by maintaining optimal air temperatures, even under load.

Flexibility for the Future –

The Hurricane engine family, including both the H/O and Standard Output (S/O) variants, is built with flexibility in mind, allowing Stellantis to adapt to the evolving needs of the automotive industry. This versatility positions Stellantis to meet shifting market demands and regulatory requirements, especially as the company pushes toward its Dare Forward 2030 sustainability goals. By balancing power, efficiency, and reduced emissions, the Hurricane engine lineup ensures Stellantis can offer high-performance options while supporting its commitment to a greener future.
