I njected with an unmatched 707 horsepower courtesy of an awe-inspiring supercharged 6.2-liter V-8 engine, the most awarded SUV ever and the most capable full-size SUV on the planet has been transformed into the most powerful and quickest SUV ever: The new 2018 Jeep Grand Cherokee Trackhawk.
The new benchmark 707-horsepower supercharged engine combines with an upgraded high-torque capacity TorqueFlite eight-speed automatic transmission, worldclass on-road driving dynamics and new Brembo brakes to deliver a new level of performance: 0-60 miles per hour (mph) in 3.5 seconds, quarter mile in 11.6 seconds at 116 mph, top speed of 180 mph, 60-0 mph braking distance in 114 feet and .88 g capability on the skid pad.
“Long recognized as the full-size SUV capability leader, Jeep Grand Cherokee is now the most powerful and quickest SUV as well, with the introduction of our new 707-horsepower Trackhawk,” said Mike Manley, Head of Jeep Brand – FCA Global. “The new Grand Cherokee Trackhawk delivers astounding performance numbers, backed by renowned SRT engineering that combines world-class on-road driving dynamics with luxury, refinement and an array of innovative advanced technology.”
The breakthrough supercharged engine is designed and manufactured using only the strongest and most durable materials. Its cast iron block features water jackets between the cylinders for optimal cooling. A forgedsteel crankshaft with induction-hardened bearing surfaces is so strong it can withstand firing pressures of nearly 1,600 psi (110 bar) – the equivalent of five family sedans standing on each piston, every two revolutions. The unique, specially tuned crankshaft damper has been burst tested to 13,000 rpm. Air sources for the supercharger include a cold-air scoop in the lower front fascia, which replaces the driver’s-side fog lamp and helps to feed the 92mm throttle body.
Trackhawk’s standard TorqueFlite eightspeed automatic transmission delivers improved shift response, quality and consistent performance and drivability. The transmission software takes into account variables such as engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map.
Grand Cherokee Trackhawk is equipped with the Jeep Quadra-Trac on-demand four-wheel-drive system, which includes an electronic limited-slip rear differential and a single-speed active transfer case. The new, full-time active transfer case uses forged steel chain sprockets and a wider chain for added strength and durability.
Jeep Grand Cherokee Trackhawk is capable of towing 7,200 pounds.
Built in Detroit at the Jefferson North Assembly Plant, the 2018 Grand Cherokee Trackhawk will arrive in Jeep showrooms in the fourth quarter of 2017.
