Jeep Grand Cherokee Hurricane Engine : Twin Turbo Suv Engine

The Jeep Grand Cherokee Hurricane engine brings twin-turbo power to an SUV already known for capability. This new powertrain option changes everything you thought you knew about mid-size SUVs. If you are shopping for a Grand Cherokee, the Hurricane engine deserves your full attention.

This article covers everything about the Hurricane engine in the Grand Cherokee. You will learn how it performs, how it compares to older engines, and what it means for your driving experience. Let’s get started.

Jeep Grand Cherokee Hurricane Engine

The Hurricane engine is a 3.0-liter twin-turbocharged inline-six. It replaces the aging V8 options in the Grand Cherokee lineup. Jeep designed this engine to deliver more power with better fuel economy.

Two versions are available. The standard output produces 420 horsepower and 468 lb-ft of torque. The high-output version cranks out 510 horsepower and 500 lb-ft of torque. That is more power than the old 6.4-liter V8.

Key Specifications Of The Hurricane Engine

  • Displacement: 3.0 liters
  • Configuration: Inline-six cylinder
  • Induction: Twin turbochargers
  • Fuel system: Direct injection
  • Block material: Aluminum
  • Compression ratio: 10.5:1
  • Redline: 6,100 rpm

The engine uses a hot-vee layout. The turbos sit inside the V between the cylinder heads. This design reduces lag and improves throttle response. You get power almost instantly when you step on the gas.

How The Hurricane Compares To The Old V8

The old 5.7-liter Hemi V8 made 357 horsepower. The 6.4-liter made 475 horsepower. The Hurricane beats both in power and torque. It also weighs less because of the aluminum construction.

Fuel economy is better too. The Hurricane engine gets an estimated 18 mpg city and 25 mpg highway. The old V8s struggled to reach 15 mpg combined. You save money at the pump without losing performance.

Towing capacity remains strong. The Grand Cherokee with the Hurricane can tow up to 7,200 pounds. That is enough for a small boat or a camper trailer.

Performance And Driving Experience

You feel the Hurricane engine the moment you accelerate. The twin turbos spool quickly and push you back into your seat. There is no lag like older turbo engines. Power builds smoothly from low rpm all the way to redline.

The eight-speed automatic transmission pairs perfectly with the engine. Shifts are quick and smooth. You can use paddle shifters for manual control if you want more involvement.

Jeep tuned the exhaust to sound aggressive. It is not as loud as a V8, but it has a deep, sporty note. You hear the turbos whistle under hard acceleration. It sounds like a proper performance SUV.

Acceleration Numbers

  1. 0-60 mph: 4.5 seconds (high-output)
  2. Quarter mile: 12.9 seconds
  3. Top speed: 155 mph (electronically limited)

These numbers put the Grand Cherokee Hurricane in sports car territory. It is faster than many sedans and coupes. You will surprise people at stoplights.

Handling And Ride Quality

The Hurricane engine does not upset the Grand Cherokee’s balanced handling. The SUV still feels planted and stable. The optional air suspension helps keep body roll in check.

You can choose from multiple drive modes. Sport mode sharpens throttle response and holds gears longer. Off-road mode adjusts the suspension for rough terrain. The engine works well in all conditions.

Braking is strong with large discs all around. You stop confidently even when towing or carrying heavy loads. The Grand Cherokee feels secure at high speeds.

Technology And Engineering Behind The Hurricane

Jeep used advanced engineering to make the Hurricane engine reliable and efficient. The twin turbos are small and lightweight. They spool quickly and reduce lag. Each turbo feeds three cylinders.

Direct injection sprays fuel directly into the combustion chamber. This improves efficiency and power. The fuel system operates at high pressure for better atomization.

The engine uses a variable valve timing system. It adjusts intake and exhaust timing for optimal performance. You get more torque at low rpm and more power at high rpm.

Cooling And Lubrication

Turbocharged engines run hot. Jeep designed a robust cooling system for the Hurricane. There is an electric water pump and a large radiator. Oil coolers keep the engine temperature in check.

The lubrication system uses a variable displacement oil pump. It delivers exactly the amount of oil needed. This reduces parasitic loss and improves fuel economy.

You should use synthetic oil for best performance. Jeep recommends 0W-20 viscosity. Oil changes are needed every 10,000 miles or once a year.

Durability And Reliability

The Hurricane engine has been tested extensively. Jeep put it through millions of miles of testing. The block and heads are made from high-strength aluminum. Forged steel connecting rods and crankshaft handle the power.

Early reports from owners are positive. There are no major reliability issues reported. The engine seems well built and durable. Jeep offers a 5-year/60,000-mile powertrain warranty.

Some owners have reported minor issues with the turbo wastegate actuators. These are rare and covered under warranty. Overall, the Hurricane engine appears reliable.

Fuel Economy And Efficiency

The Hurricane engine is more efficient than the V8 it replaces. EPA estimates are 18 mpg city, 25 mpg highway, and 21 mpg combined. Real-world driving often matches these numbers.

You can improve fuel economy by driving gently. Avoid hard acceleration and use cruise control on highways. The engine has a start-stop system that shuts off at idle. This saves fuel in city driving.

Towing reduces fuel economy significantly. Expect around 12-14 mpg when towing a heavy trailer. That is still better than the old V8 which got 8-10 mpg while towing.

Fuel Requirements

The Hurricane engine requires premium unleaded fuel. Octane rating should be 91 or higher. Using lower octane fuel can cause engine knock and reduce performance.

Fuel tank capacity is 24.6 gallons. You get a driving range of about 500 miles on the highway. That is good for long road trips.

Trim Levels And Availability

The Hurricane engine is available on several Grand Cherokee trim levels. You can get it on the Limited, Overland, Summit, and Summit Reserve. The high-output version is exclusive to the Trailhawk and Trackhawk replacements.

The standard Hurricane comes on the Limited and Overland. These trims start around $55,000. The high-output version costs more, starting around $65,000.

Jeep also offers the Hurricane on the Grand Cherokee L three-row model. The engine fits without modifications. You get the same performance in a larger SUV.

Comparing Hurricane To Competitors

The Hurricane engine competes with V8s from other brands. The Ford Expedition has a 3.5-liter V6 with 400 horsepower. The Chevrolet Tahoe has a 5.3-liter V8 with 355 horsepower. The Hurricane beats both in power and efficiency.

European competitors like the BMW X5 and Mercedes GLE have similar engines. The Hurricane matches them in performance but costs less. You get more value for your money.

The Grand Cherokee Hurricane is a strong contender in the mid-size SUV segment. It offers V8 power with four-cylinder fuel economy. That is a winning combination.

Maintenance And Ownership Costs

Owning a Hurricane engine Grand Cherokee is affordable. Maintenance costs are similar to other turbocharged engines. Oil changes cost around $80 at a dealership. You can do it yourself for about $50.

Spark plugs need replacement every 60,000 miles. The turbochargers are designed to last the life of the engine. Air filters should be changed every 30,000 miles.

Insurance costs are higher than the base V6 model. The Hurricane engine is considered a performance option. Expect to pay about 10-15% more for insurance.

Common Maintenance Schedule

  • Oil change: Every 10,000 miles
  • Tire rotation: Every 7,500 miles
  • Air filter: Every 30,000 miles
