Jeep 3.0L Hurricane
Twin-Turbo H.O.

For drivers who refuse to compromise on power, the Jeep 3.0L Hurricane Twin-Turbo High Output (H.O.) engine offers a level of performance that was previously impossible in a full-size SUV. Exclusive to the Grand Wagoneer, this powertrain proves that raw displacement is no longer the only path to dominance.

The H.O. engine delivers immediate, surging power that makes the massive Grand Wagoneer feel surprisingly agile. It runs smoother, pulls harder, and stays quieter than the V8 it replaced.

3.0L Hurricane Twin-Turbo H.O. Specs

The High Output engine is a significant leap forward from the standard version found in the regular Wagoneer. With the 2025 updates, it now stands as the most powerful six-cylinder engine in its class, easily outpacing competitors.

The H.O. Difference: Built for Boost

You cannot simply "chip" a standard Hurricane engine to match the High Output. Jeep engineers fundamentally redesigned the hardware to withstand extreme heat and pressure.

Forged Internals: Unlike the cast pistons in the standard engine, the H.O. uses forged aluminum pistons. These are essential for surviving the intense cylinder pressures generated by high boost levels.

Dual Fuel Pumps: To feed the cylinders at over 5,000 PSI, this engine utilizes two high-pressure fuel pumps. This ensures you never run lean during wide-open throttle merges in Carmel or Fishers.

Optimization: The compression ratio is dropped to 9.5:1, a critical adjustment that allows the turbos to push more air without causing engine-damaging knock.

Available Models with the 3.0L Hurricane H.O.

This engineering marvel is reserved exclusively for the flagship of the Jeep brand.

The H.O. comes standard. It moves this luxury fortress with authority, providing passing power that makes highway driving effortless.

Even with the added length and weight of the extended wheelbase, the 500+ lb-ft of torque ensures you can carry eight passengers and their luggage through the hills of Anderson without the engine ever feeling strained.

Note: The standard Wagoneer is equipped with the Standard Output (S.O.) engine. If you demand the forged internals and maximum horsepower, the Grand Wagoneer is your only choice.

At Ed Martin Chrysler Dodge Jeep Ram, we remove that uncertainty. We verify the engine's integrity so you can enjoy the performance without the worry.

Certified Pre-Owned Program Certified Pre-Owned Cars

CPO Safety Net

Our Certified Pre-Owned Grand Wagoneers undergo a rigorous inspection of the powertrain's most critical components.

  • Fuel System Verification: We test the dual mechanical fuel pumps to ensure they are delivering consistent pressure, which is vital for engine longevity.
  • Compression Health: We perform tests to verify the forged pistons and rings are sealing perfectly, ensuring the engine produces every bit of its rated horsepower.
  • Warranty Protection: You drive away with a 7-Year/100,000-Mile Powertrain Limited Warranty that covers the twin turbos, intercoolers, and the engine block itself.

Maintenance Pro-Tips

The H.O. engine shares more DNA with supercars than with standard SUVs. To keep it running like new, our Service Center recommends the following:

Maintenance Pro-Tips
  • Premium Fuel is Mandatory: You cannot use regular gas in the H.O. engine. It requires 91+ octane to prevent knock. If you use low-grade fuel, the computer will drastically cut power to save the engine.
  • Specialized Oil: This engine requires 0W-40 Synthetic Oil, which is thicker than the 0W-20 used in the standard model. This provides the necessary film strength to protect bearings under high-boost heat.
  • The Morning Warm-Up: On cold mornings in Lawrence, let the engine idle for 30 seconds before shifting into gear. This ensures the high-pressure oil lines have fully pressurized the turbos before they start spinning up.
