VIDEO: 2018 JEEP GRAND CHEROKEE TRACKHAWK DOES 0-60MPH IN JUST 3.4 SECONDS!

A 5,300-pound SUV hitting 60 mph in the time it takes to read this sentence sounds like a typo, but Patrick Rall’s in-car footage of a 2018 Jeep Grand Cherokee Trackhawk running its Launch Control system proves the number is real. Two runs, two nearly identical times, and a supercharged engine borrowed straight from a Hellcat explain how a family hauler ended up embarrassing sports cars at stoplights.

Numbers stop meaning much once you’ve seen enough of them, but 3.4 seconds to 60 mph for a three-row, five-passenger SUV built primarily to haul groceries and kids to soccer practice is the kind of figure that demands a second look no matter how numb an enthusiast has become to horsepower wars. Patrick Rall’s in-car footage of a 2018 Jeep Grand Cherokee Trackhawk running that exact number, twice, with a slowest recorded run of 3.6 seconds, isn’t a fluke or a favorable wind. It’s the direct, repeatable result of Jeep dropping one of the most notorious engines in modern Stellantis history into a vehicle nobody expected to see it in.

A Number That Sounds Like a Typo

That engine is the supercharged 6.2-liter Hemi V8 lifted essentially wholesale from the Dodge Challenger and Charger Hellcat, producing 707 horsepower and 645 lb-ft of torque in Trackhawk trim, output figures that would have seemed absurd for any SUV a decade earlier and remain startling even now. Jeep’s engineers didn’t simply bolt the Hellcat engine into an existing Grand Cherokee chassis and call it finished; the Trackhawk required reinforced axles, upgraded brakes borrowed from high-performance applications, a specific all-wheel-drive calibration to manage that much torque across all four corners, and a transmission tune capable of surviving repeated full-throttle launches without grenading itself.

Borrowing the Hellcat’s Heart for an SUV

Launch Control, the system Rall specifically references testing in this footage, is the electronic choreography that makes a run like this possible without simply spinning the tires uselessly off the line. The system holds engine RPM at a predetermined level while the driver stands on the brake, then manages throttle and clutch or torque-converter engagement the instant the brake releases, coordinating far more precisely than a human foot ever could to put maximum power to the ground without overwhelming available traction. Getting that calibration right on an all-wheel-drive SUV weighing well over two and a half tons is a considerably harder engineering problem than tuning the same system for a lighter, rear-drive muscle car.

What Launch Control Actually Does

Torque Reserve, the second system Rall mentions testing, works alongside Launch Control to solve a specific problem with forced-induction engines: supercharger lag. By keeping the throttle plate partially open and the supercharger spun up even while the driver holds the brake pedal during a launch, Torque Reserve ensures boost is already present the instant the brake releases, eliminating the split-second delay that would otherwise cost precious tenths off the run. It’s a detail most casual observers would never notice watching a launch, but it’s exactly the kind of engineering nuance that separates a genuinely quick factory calibration from one that merely sounds fast.

Torque Reserve: The Trick Behind the Trick

Consistency matters as much as the peak number here. A single 3.4-second run could be dismissed as a favorable combination of temperature, surface grip, and driver technique lining up perfectly once. Rall’s footage recording that same 3.4-second result and a 3.6-second backup run on the same outing demonstrates the Trackhawk’s launch systems delivering repeatable performance rather than a one-off lucky pull, which is a far more meaningful data point for anyone actually trying to understand what the vehicle can do reliably rather than what it managed once under ideal conditions.

3.4 Seconds, Twice, Not by Accident

Put those numbers next to genuine sports cars and the comparison gets uncomfortable for a lot of two-door performance vehicles. A 3.4-second Trackhawk keeps pace with, and in some cases outright beats, contemporary Corvettes, BMW M cars, and plenty of dedicated sports coupes costing similar or greater money, all while offering seating for five, a full-size cargo area, and genuine daily-driver comfort and weather capability that none of those rivals can match. That combination is exactly why the Trackhawk became such a talking point in performance circles: it broke the assumption that genuine supercar-adjacent acceleration required giving up practicality entirely.

What 707 Horsepower Does to a Family SUV’s Reputation

None of this happens without engineers first solving a much less glamorous problem: mass. A Grand Cherokee Trackhawk tips the scales north of 5,300 pounds, more than double what a lightweight sports car needs to move to hit comparable acceleration numbers, which means every one of those 707 horsepower had to overcome a genuinely enormous weight penalty just to get into the conversation at all. That reality makes the 3.4-second result more impressive rather than less, since it required not just raw output but a chassis, all-wheel-drive system, and tire package all engineered specifically to translate that power into forward motion rather than wheelspin, body roll, or an ABS system working overtime to keep the vehicle pointed straight during a full-throttle launch from a dead stop. Overcoming that much mass without simply burning through rear tires or overheating the drivetrain within a handful of runs is arguably the harder engineering achievement, and it’s the part of the story a raw 0-60 number never fully communicates on its own.

The Weight the Engineers Had to Beat

The Trackhawk didn’t invent the performance SUV category, but it pushed the segment’s ceiling dramatically higher than anything that came before it, forcing rivals like the BMW X5 M and Mercedes-AMG GLE63 to take notice and respond. Half a decade removed from its debut, the Trackhawk remains a benchmark discussed whenever the performance SUV conversation comes up, and footage like Rall’s, showing the actual launch systems working in real time rather than simply quoting a spec sheet number, is exactly the kind of documentation that explains why the reputation stuck. It’s the difference between a marketing figure and a repeatable, in-car demonstration of a genuinely radical piece of engineering. Watch the launch back to back and that difference becomes impossible to argue with. A 5,300-pound SUV shouldn’t be able to do this, and yet here it is, doing it twice in a row. That’s the Trackhawk’s whole reputation in a single clip. Numbers this repeatable stop being a fluke and start being a benchmark.

The Engine Connects It to Dodge’s Muscle Car Lineup

The Trackhawk’s straight-line performance is not a coincidence of engineering happening in isolation at Jeep; it borrows its supercharged 6.2-liter V8 directly from the Dodge Challenger and Charger Hellcat models built on the same corporate parts shelf. FCA’s decision to drop that engine into a three-row SUV platform was as much a marketing statement as an engineering one, proving the same supercharged Hemi architecture that powered modern muscle cars could be adapted to a taller, heavier vehicle without losing its character. That shared-engine strategy is part of a broader pattern at the company, where a single powerful V8 gets spread across as many nameplates as possible to spread out its development cost. For muscle car fans, the Trackhawk is really a reminder that the supercharged Hemi’s influence extends well past the two cars most people associate it with.
