Stellantis can chalk up another award for its Hurricane 3.0-liter High Output (H/O) Straight-Six Turbo (SST) engine. The engine powering the all-new 2025 Ram 1500 has been named to the prestigious Wards 10 Best Engines & Propulsion Systems list for 2024. This marks the second time the Hurricane has received this honor, showcasing its prowess as a top-tier engine in the competitive light-duty pickup truck segment.
Stellar Recognition for Stellantis
The inclusion of the Hurricane H/O SST engine in the 2024 list also extends Stellantis’ (previously FCA) winning streak to eight consecutive years, demonstrating the company’s continued excellence in propulsion system engineering. Recognized for its power, efficiency, and advanced technology, the Hurricane SST engine solidifies Stellantis’ leadership 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 Hurricane H/O engine delivers a remarkable 540 horsepower and 521 lb.-ft. of torque in the 2025 Ram 1500 Tungsten, Limited, Longhorn, and RHO models, surpassing all traditional naturally aspirated V8s and competing boosted six-cylinder engines in the segment. It is paired with a TorqueFlite eight-speed automatic transmission, which provides seamless shifts while optimizing fuel efficiency, drivability, and performance.
Bob Gritzinger, Ward’s editor-in-chief, praised the engine’s performance, saying, “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 rabid V-8 buyer into the 6-cylinder family.”
A Clean-Sheet Design with Advanced Technology
As part of Stellantis’ commitment to its Dare Forward 2030 strategic plan, the Hurricane High Output Straight-Six Turbo represents a forward-thinking approach to engine design. This engine was built from the ground up with a clean-sheet design, leveraging cutting-edge technologies to balance power, fuel economy, and emissions reductions.
Among the notable innovations are:
- Dual low-inertia turbochargers: Designed to optimize airflow by feeding three cylinders each, the turbochargers ensure rapid throttle response, enhancing both performance and efficiency.
- Plasma transfer wire arc coating: Applied to the cylinder bores, this technology creates an ultra-thin, low-friction wear surface that boosts longevity and fuel economy.
- High-pressure direct fuel injection: Operating at 5,075 psi (350 bar), the direct injection system delivers precise fuel atomization, resulting in better combustion and reduced emissions.
- Water-to-air charge cooler: Mounted directly on the engine with a dedicated cooling circuit, this system maintains optimal air temperatures, ensuring consistent performance even under load.
Flexibility for the Future
The Hurricane engine family, including the High Output and Standard Output variants, is designed to meet the evolving needs of the automotive industry. This versatility ensures that Stellantis can adapt its offerings to shifting market demands and regulations, especially as it works towards its 2030 sustainability goals.
