How Much Horsepower Does a Jeep Trackhawk Have? The Heart of a Hellcat
Let’s cut straight to the chase. When people ask, “how much horsepower does a Jeep Trackhawk have?” they’re often expecting a big number, but the reality still manages to shock. The Jeep Grand Cherokee Trackhawk, introduced for the 2018 model year, truly brought supercar-level performance to the SUV segment.
Under its aggressively styled hood beats the heart of a monster: the supercharged 6.2-liter HEMI V8 engine. This isn’t just any V8; it’s the same engine found in the Dodge Challenger and Charger Hellcat models.
Specifically, the Jeep Trackhawk boasts an astonishing 707 horsepower and 645 lb-ft of torque. These figures aren’t just impressive for an SUV; they rival, and often surpass, many dedicated sports cars and supercars on the market.
The Supercharger Advantage: Forced Induction Explained
A big part of the Trackhawk’s immense power comes from its supercharger. Unlike naturally aspirated engines, which rely solely on atmospheric pressure to draw air in, a supercharger forces compressed air into the engine’s cylinders.
This “forced induction” allows more oxygen into the combustion chamber, which, when combined with more fuel, creates a significantly larger explosion and, consequently, much more power. The Trackhawk’s IHI twin-screw supercharger is a key player in its incredible output.

Knowing how much horsepower a Jeep Trackhawk has is one thing, but understanding what that power translates to on the road is another. This isn’t just a powerful engine; it’s a meticulously engineered vehicle designed to put that power down efficiently and effectively.
The Trackhawk’s performance figures are staggering for a vehicle of its size and weight.
- 0-60 MPH: It can launch from 0 to 60 miles per hour in a blistering 3.5 seconds. This puts it in the same league as many high-end sports cars.
- Quarter-Mile: The Trackhawk can cover a quarter-mile drag strip in just 11.6 seconds, hitting speeds of around 116 mph.
- Top Speed: Its top speed is electronically limited to 180 mph.
These numbers are achieved thanks to a combination of the monstrous engine, a robust drivetrain, and advanced traction management systems.
The Driving Experience: Taming the Beast
Driving a Trackhawk is an experience like no other. The moment you press the start button, the supercharged HEMI barks to life with an aggressive growl. Under acceleration, the whine of the supercharger is a symphony of power, a distinct sound that signals serious business.
The acceleration is brutal, pushing you firmly back into your seat. Despite its SUV stature, the Trackhawk handles surprisingly well, thanks to its performance-tuned suspension and massive tires. However, it’s crucial to remember that you’re piloting a heavy, incredibly powerful machine.
Respect for its capabilities and proper driving technique are paramount for safety and enjoyment.
What Makes the Trackhawk So Powerful? Engineering Deep Dive
Achieving 707 horsepower in an SUV requires more than just dropping a big engine into a chassis. Jeep and SRT engineers had to strengthen virtually every component of the drivetrain and chassis to handle the immense forces generated by the supercharged HEMI.
Engine Enhancements for Extreme Power
While sharing the Hellcat engine, the Trackhawk’s specific application required some unique considerations. The 6.2L HEMI V8 features a forged steel crankshaft, forged alloy pistons, and powdered-metal connecting rods. These components are designed to withstand the extreme pressures and temperatures of forced induction.
The supercharger itself is a 2.4-liter IHI unit, capable of spinning up to 14,600 rpm and generating 11.6 psi of boost. A dedicated intercooler system keeps intake air temperatures down, maximizing power output and preventing detonation.
Robust Drivetrain and Transmission
To put 707 horsepower to the ground reliably, a regular SUV drivetrain simply wouldn’t cut it. The Trackhawk utilizes an upgraded TorqueFlite 8HP95 eight-speed automatic transmission, specially calibrated for high-performance applications.
The Quadra-Trac Active On-Demand 4×4 system is also heavily reinforced. It features a stronger rear axle, a beefed-up transfer case, and an electronic limited-slip differential. These components work together to distribute power effectively to all four wheels, ensuring maximum traction during hard acceleration.
Braking and Suspension Systems
What goes fast must also stop fast. The Trackhawk is equipped with massive Brembo brakes, featuring 15.75-inch two-piece rotors up front with six-piston calipers, and 13.78-inch rotors in the rear with four-piston calipers. These brakes provide exceptional stopping power, which is absolutely critical for a vehicle with this level of performance.
The suspension system also receives significant upgrades. It features adaptive Bilstein dampers that allow for various driving modes, from comfortable cruising to aggressive track use. This helps manage the vehicle’s weight and power, keeping it stable and controlled.
Living with a Trackhawk: Maintenance, Fuel, and Ownership Considerations
Owning a vehicle with
