Hurricane High Output Straight-Six Turbo Makes Wards 10 Best Engines List

When developing the Hurricane engine family, Stellantis was well aware that any engine proposing to replace its legendary Hemi V-8 would have to be very special. It had to be powerful, durable, smooth, and full of character. As proof of its efforts, Krusen Motors is proud to announce that Wards Auto has designated the 3.0-liter Hurricane High Output (H/O) Straight-Six Turbo (SST) engine as one of its 2024 Wards 10 Best Engines & Propulsion Systems.

Stellantis is no stranger to this accolade, thanks in part to those very same Hemi engines the Hurricane replaces. This is the eighth consecutive year that a Stellantis propulsion system has earned a spot as one of Wards 10 Best Engines. It is also the second time a 3.0-liter Hurricane twin-turbo engine has been honored by Wards editors.

“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 of 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 NHV in one package.”In its application in the 2025 Ram 1500 Tungsten, the 3.0-liter Hurricane High Output Straight-Six Turbo produces a horsepower figure of 540 (at 5,700 rpm) and torque figure of  521 lb-ft (at 3,500 rpm). The engine is paired with a TorqueFlite eight-speed automatic transmission.“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,” says Bob Gritzinger, Wards editor-in-chief. “I like the assured rumble from the High-Output I-6. This engine should sway even the most rabid V-8 buyer into the 6-cylinder family.”

The High-Output is the most powerful of the two engines in the Hurricane family. Even the lower-output version features a deep-skirt cast-aluminum block with a structural aluminum alloy oil pan. It is the strongest engine in Ram history, with cross-bolted steel main bearing caps to secure the strong rotating assembly, which includes a forged steel crankshaft and forged steel connecting rods. The block is deck-plate honed to optimize the cylinder bore shape, contributing to improved fuel efficiency. The twin-turbo is a parallel arrangement, with each turbocharger feeding three cylinders. Fuel is introduced by direct injection, and a plasma transfer wire arc coating is applied to each cylinder for a very low-friction surface.  

Amidst extensive development of electric drivetrains, Stellantis invested in this engine family knowing that gas-powered trucks and high-performance cars would still be with us for a while. 

The Hurricane High Output is in the 2025 Ram 1500 RHO, Limited, Limited Longhorn, and Tungsten models. Visit Krusen Motors to experience this award-winning engine.
