The 3.0-liter Hurricane High Output (H/O) Straight-Six Turbo (SST) engine, as tested in a 2025 Ram 1500 Tungsten, has earned a 2024 Wards 10 Best Engines & Propulsion Systems award.

The recognition marks the eighth consecutive year that a Stellantis propulsion system has earned a spot on the prestigious list, according to the company. It also represents 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 efficient, robust and versatile, delivering performance that enhances the driving experience both on- and off-road,” said Micky Bly, head of global propulsion systems at Stellantis. “The 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 in one package.”

The 3.0-liter Hurricane High Output Straight-Six Turbo delivers 540 horsepower and 521 pound-feet of torque. It is paired with a TorqueFlite 8-speed automatic transmission, which optimizes shifting for fuel economy, performance and drivability.

“The Hurricane High-Output Straight-Six Turbo packs a powerful punch from launch to well past legal speed, while delivering promised fuel economy that improves on the Hemi V-8 it replaces,” says Bob Gritzinger, Wards editor-in-chief. “The assured rumble from the High-Output I-6 should sway even the most rabid V-8 buyer into the 6-cylinder family.”

The foundation of the Hurricane Twin Turbo I-6 engine is a deep-skirt cast-aluminum block with a structural aluminum alloy oil pan. It uses cross-bolted steel main bearing caps to secure the strong rotating assembly, which includes a forged steel crankshaft and forged steel connecting rods. During manufacturing, the block is deck-plate honed to optimize the cylinder bore shape, contributing to improved fuel efficiency.

Stellantis propulsion system engineers incorporated innovative technologies to deliver reduced emissions and achieve big-engine power, including:

  • Two low-inertia, high-flow turbochargers, optimized for each engine, which feed three cylinders each for rapid throttle response
  • Plasma transfer wire arc (spray bore) coating in the cylinder bores for an ultra-thin, low-friction wear surface
  • High-pressure (5,075 psi/350 bar) direct fuel injection
  • Engine-mounted water-to-air charge cooler with a dedicated cooling circuit

The 3.0-liter Hurricane engines are produced at Stellantis’ Saltillo Engine Plant in Mexico.
