Achieving a top speed of 180 mph in a vehicle with the size and weight of an SUV is no small feat. It requires more than just raw power; it demands sophisticated engineering, meticulous aerodynamic design, and a chassis capable of handling extreme forces.
Jeep engineers went to great lengths to ensure the Trackhawk’s stability and safety at high speeds. While its SUV silhouette might not scream "aerodynamic," subtle yet effective design elements contribute to its high-speed prowess. The front fascia, for instance, is not just for aesthetics; it’s designed to optimize airflow, reduce lift, and channel air to cool the engine and brakes. The lowered stance, specific hood vents, and integrated rear spoiler further aid in managing airflow and maintaining downforce.
Underneath the muscular exterior, the chassis is significantly reinforced to handle the immense power and G-forces. The Trackhawk features a high-performance adaptive damping suspension system (Bilstein adaptive shocks), which constantly adjusts to provide optimal ride and handling characteristics, whether cruising or pushing the limits on a track. Larger, high-performance Brembo brakes (15.75-inch front rotors with six-piston calipers) are fitted to ensure that the vehicle can shed speed just as quickly as it gains it, a critical safety feature when operating at such velocities. Special performance-oriented tires (Pirelli Scorpion Verde All-Season or optional P Zero Summer tires) are also crucial, providing the necessary grip and stability. Every component, from the steering system to the cooling capacity, is engineered to sustain the rigors of high-speed performance, making the 2019 Trackhawk a true engineering marvel.
