The Heart of the Beast: Understanding the Powertrain
2018 Jeep Trackhawk Top Speed: Unleashing the Beast
To comprehend how a 5,363-pound SUV could reach speeds once exclusive to high-performance coupes, one must first look under the hood. The 2018 Jeep Trackhawk is powered by the legendary supercharged 6.2-liter HEMI V8 engine, affectionately known as the "Hellcat" engine. This monstrous powerplant is the same one found in the Dodge Challenger SRT Hellcat and Charger SRT Hellcat, adapted for SUV duty.
- Raw Power: This engine churns out an astounding 707 horsepower and 645 lb-ft of torque. The supercharger, a mechanical air compressor, forces more air into the engine’s cylinders, significantly boosting power output. The distinctive whine of the supercharger is a tell-tale sign of the immense forces at play.
- Seamless Power Delivery: Mated to this behemoth is a specially calibrated TorqueFlite 8HP95 eight-speed automatic transmission. This robust transmission is designed to handle the immense torque and facilitate rapid, smooth shifts, ensuring that power is delivered efficiently to all four wheels.
- Heavy-Duty Drivetrain: Unlike its rear-wheel-drive Hellcat siblings, the Trackhawk employs a sophisticated Quadra-Trac Active On-Demand 4×4 system. This system features a full-time transfer case, a strengthened rear axle with a tougher limited-slip differential, and stronger driveshafts. These components are all fortified to withstand the extreme forces generated during hard acceleration and high-speed runs, ensuring durability and optimal traction.
The synergy between this supercharged engine, the intelligent transmission, and the fortified all-wheel-drive system is what transforms the Trackhawk from a mere SUV into a legitimate speed demon, laying the foundation for its remarkable top speed.
Beyond the Engine: Aerodynamics and Chassis Integrity
While raw power is crucial, it’s not the only factor in achieving and sustaining high speeds, especially for a vehicle with the inherent aerodynamic challenges of an SUV. Jeep engineers had to consider more than just brute force.
- Aerodynamic Tweaks: SUVs are typically not designed for low drag coefficients. However, the Trackhawk features subtle yet effective aerodynamic enhancements. Its distinctive front fascia, with larger air intakes, isn’t just for cooling; it also helps manage airflow. The unique hood with dual heat extractors aids in cooling the supercharged engine and contributes to airflow management. While not as slippery as a sports car, these modifications help reduce lift and drag at higher velocities.
- Robust Chassis and Suspension: To handle speeds approaching 180 mph, the Trackhawk’s chassis needed significant reinforcement. It features a high-performance adaptive damping suspension system from Bilstein, which automatically adjusts damping forces to optimize handling and stability based on driving conditions and selected drive modes (Track, Sport, Auto, Tow, Snow). This ensures the vehicle remains composed and predictable at speed.
- Superior Braking System: Speed is only half the equation; the ability to stop is equally, if not more, important. The Trackhawk is equipped with the largest front brakes ever fitted to a Jeep vehicle: 15.75-inch (400 mm) two-piece vented rotors with six-piston Brembo calipers up front, and 13.78-inch (350 mm) vented rotors with four-piston Brembo calipers at the rear. This colossal braking system provides exceptional stopping power, crucial for managing the immense kinetic energy at high speeds.
- Performance Tires: The Trackhawk rides on wider, stickier Pirelli Scorpion Verde All-Season or optional Pirelli P Zero three-season tires, mounted on 20-inch wheels. These tires are designed to provide maximum grip and stability, vital for maintaining traction and control during high-speed maneuvers and straight-line runs.
These comprehensive engineering efforts – from managing airflow to ensuring a stable platform and effective stopping power – are what allow the Trackhawk to not only reach its top speed but do so with a commendable degree of control and safety.
The Official Top Speed: Numbers and Reality
Now, for the number everyone wants to know: what is the official top speed of the 2018 Jeep Trackhawk?
Jeep officially states the 2018 Grand Cherokee Trackhawk has an electronically limited top speed of 180 mph (290 km/h).
It’s crucial to understand that this is an electronically governed speed. While the engine might be capable of pushing the vehicle even further, the limitation is put in place for various reasons, including tire ratings, aerodynamic stability, and overall vehicle dynamics at extreme velocities.
Factors Influencing Real-World Top Speed:
While 180 mph is the official figure, achieving it in the real world can be influenced by several factors:
- Road Conditions: A perfectly smooth, flat, and straight road is ideal. Any imperfections can affect stability and drag.
- Environmental Factors: Headwinds can significantly reduce achievable top speed, while tailwinds can slightly increase it. Air temperature and density also play a role; colder, denser air provides more oxygen for combustion but also increases aerodynamic drag.
- Elevation: Higher altitudes mean thinner air, which can reduce engine power output and thus top speed.
- Vehicle Load: The weight of passengers and cargo will impact acceleration and, marginally, top speed.
- Tire Pressure: Correct tire pressure is vital for optimal performance and safety at high speeds.
- Driver Skill: While top speed on a straight line is less about skill than handling, smooth inputs and consistent acceleration are still beneficial.
In essence, the 180 mph figure is a testament to its engineering prowess, placing it in an elite category of performance vehicles, far surpassing the capabilities of traditional SUVs and even challenging many dedicated sports cars.
Achieving and Maintaining High Speeds: Important Considerations
It cannot be stressed enough: attempting to achieve the 2018 Jeep Trackhawk’s top speed should never be done on public roads. It is illegal, incredibly dangerous, and puts lives at severe risk.
- Safety First: Closed Courses Only: The only appropriate environment for exploring a vehicle’s top speed is a certified, professional closed course, such as a dedicated test track or a long, straight airstrip, under controlled conditions.
- Professional Guidance: Even on a closed course, it is highly recommended to have professional drivers or instructors present, especially when pushing a vehicle to its limits. They can provide guidance on vehicle dynamics at speed and emergency procedures.
- Vehicle Preparation is Key: Before any high-speed run, ensure the vehicle is in optimal condition. This includes checking tire pressure, fluid levels (oil, coolant), brake pad wear, and overall mechanical integrity. Any overlooked issue can become catastrophic at high speeds.
- Understanding Vehicle Dynamics: At 180 mph, even minor steering inputs can have significant effects. The driver must be aware of the vehicle’s behavior, potential for oversteer or understeer, and how external factors like crosswinds can influence stability.
- Safety Gear: For any high-speed testing, appropriate safety gear, including helmets and fire-resistant suits, should be worn.
