2018 Jeep Grand Cherokee Trackhawk Review & Changes – They are the car equivalents of a Daytona Seaside springtime-split hookup, the sort of ride that your father may high-five you (powering Mom’s back) for buying. But what if there has been a Hellcat vehicle tame sufficient, comparatively speaking, to take residence and introduce to Mom?
2018 Jeep Grand Cherokee Trackhawk Engine & Performance
The Jeep Grand Cherokee Trackhawk is the 3rd Fiat Chrysler vehicle to get the unhinged supercharged V-8 filled under its hood, and it is the peaceful Hellcat next door. Not practically, of course-have, you heard a blown Hemi V-8 at full whack?-but with regular all-wheel-drive mitigating the engine’s tire-spinning proclivities, plus its under-the-radar appears, the Trackhawk can at the very least pass for an upstanding resident.
With more traction than any Hellcat yet, the Trackhawk has quite a great deal of poker despite its pork-the engine adds 259 pounds over the already heavy 475-hp Grand Cherokee SRT. Nevertheless, Jeep claims it can reach 60 mph in 3.5 seconds. That time is on par with the nearly 1000-pounds-less heavy, automatic-equipped Dodge Hellcats we have examined. (The quickest was the Charger, which achieved 60 mph in 3.4 seconds.) For each Jeep, the quarter-mile is supposed to fly by in 11.6 seconds (at 116 mph!), and, with no electronic governor, the Trackhawk is believed to surrender to an atmospheric level of resistance at 180 mph. Assisting this SUV to move out in a hurry is a Torque Reserve launch-control feature that briefly contains the supercharger bypass valve sealed while cutting spark and fuel to specific cylinders to limit torque before the brake is released. This widget is discussed with the Dodge Challenger SRT Demon. The supercharged 6.2-liter Hemi V-8 is mostly left alone or else, right as a result of its forged pistons, sodium-loaded exhaust valves, heavy-duty bearings, and blower driving as a lot as 11.6 psi. Exhaust-routing issues reduce peak torque by a negligible 5 lb-ft, to 645. To keep the Hellcat from lunching the Trackhawk’s driveline, Jeep fortifies the eight-speed automatic transmission, suits forged chain sprockets and a larger sequence in the transfer situation, beefs up the rear driveshaft and half-shafts, and tweaks the rear differential.
In normal functioning, the transfer case’s 40/60 front-to-rear torque split is the exact same as in the Grand Cherokee SRT; ditto the Sports mode’s 35/65 break up, the Track setting’s 30/70 division, and Snow mode’s 50/50 apportionment. The Tow setting has a 60/40 divided, but what is much more notable is the very idea that the Hellcat is graded to pull. It is! Users can pull along up to 7200 pounds, which equates either to another Hellcat-powered development or the weight of objectives for a Hellcat-powered SUV.
According to Mopar’s performance catalog, the iron-obstruct Hellcat V-8 engine and supercharger together think about 800 pounds. That is vastly bulkier than the 6.4-liter Hemi in the Grand Cherokee SRT. To compensate for the Trackhawk’s additional size, SRT engineers stiffened the front springs by 9 percent and the rears by 15 percentage and also fiddled with the electronically adaptable Bilstein dampers. The only other chassis changes are wider front and rear keeps track of (by 1.3 inches and .1 inch) in accordance with the SRT and .75-inch-bigger front brake rotors. Like the optional Brembo brake package on the SRT, the Trackhawk’s front rotors are two-part devices gripped by six-piston calipers (here decorated yellowish rather of red). Just as the regular SRT defies physics, posting .87 g on our skidpad and braking from 70 mph in 168 feet in a current test, so, also, does the Trackhawk. Jeep’s promises for the beast’s grip close to a skidpad of unspecified size (we use a 300-foot cushion) and braking from 60 mph (we test from 70 mph) are 0.88 g and 114 feet. We accumulate from the numbers that the Trackhawk need to be as remarkably equipped as the SRT model is on a track, despite the fact that car owners likely will encounter increased rates among edges.
For a Jeep with 707 horsepower, the Grand Cherokee Trackhawk is remarkably incognito. Only a handful of badges that read through “Supercharged” and “Trackhawk,” as well as the Hellcat-specific yellowish brake calipers, quad exhaust shops as an alternative of two, and exclusive 20-inch wheels differentiate the Trackhawk from the SRT. Airflow requirements for the engine also determined the deletion of the SRT’s fog lighting from the outboard front intakes.
2018 Jeep Grand Cherokee Trackhawk Interior & Exterior
Inside, only a winged Trackhawk badge on the steering wheel sets the mightiest Jeep apart-properly, that and the 200-mph speedo. The same active noise cancellation, stitched-leather dashboard and door-panel coverings, Berber carpeting, and 8.4-inch Uconnect infotainment display as the SRT are included. (Jeep provides a dyno work for immediate horsepower and torque readouts to Uconnect’s Performance Pages mobile app.) Apple CarPlay and Android Auto are normal, as properly, for anybody who cares about similar things when buying a 707-hp SUV. Ditto the adaptive cruise control, blind-spot checking, auto parking devices, lane-departure caution, and ahead-crash warning. Then again, this equipment ought to be provided, given that the Trackhawk is expected to price someplace close to $80,000.
In some way, even with a lot of big numbers floating around in this Jeep’s dialog bubble, its appearance boundaries on the mundane. We’ve been waiting years for the Hellcat to find its distance to the Grand Cherokee’s engine bay. Now it is in this article. The flatness with which that conclusion reaches is partly the mistake of the Hellcat’s normalization, the sensation that, three years right after the engine’s very first, 707-hp well-known vehicles are a portion of the everyday routine. Following all, there is now a much more powerful version of this V-8 in the 10th-group of friends-of-hell Challenger Demon. Effortlessly shed in all of this is the Trackhawk’s hegemony over the SUV dominion. Transfer more than, Bentley Bentayga, any Porsche Cayenne, and also the weirdest variations of Mercedes-Benz’s G-class-the most powerful SUV in the world, by significantly, wears a Jeep badge. That alone delivers some of the Hellcat’s original atmosphere of ridiculous to the Trackhawk, even if it can’t ” spin ” these huge car tires the way its Dodge sisters and brothers can (unless it’s chained to anything). The practical Hellcat? Safer to refer to it as the least crazy Hellcat, or the wildest production Jeep actually.
