2019 Jeep Grand Cherokee Trackhawk Review

2019 Jeep Grand Cherokee Trackhawk Review - "We are still managing physics here. I just want you to keep in mind that." So says Erich Heuschele, manager of SRT automobile dynamics to the 20 or two authors he's about to turn loose on a racetrack in the Jeep Grand Cherokee Trackhawk. We're taking care of physics, sure, but additionally an earnest effort to defy them with equivalent components horsepower and also lunacy. Claim, "707-horsepower Jeep" to any individual that hasn't already been taking note and they just wiggle a finger right into an ear as well as squint at you. "Huh?". We did drive the maximum Jeep on public roadways, but this Grand Cherokee has "track" right there in its name, so we also hit Club Motorsports, a New Hampshire club circuit so brand-new that teams were still setting up Armco the week before we appeared. It's a 2.5-mile StairMaster that works its method up and down 250 feet of altitude adjustment at a maximum 14 percent grade. Keeping his new Trackhawks from bending that fresh Armco is something Heuschele cares deeply about.

2019 Jeep Grand Cherokee Trackhawk Review

The topography, on the other hand ... no one's too anxious about that. Few things squash hills rather like 707 horsepower. Insane as it may be, the Hellcat engine at least ought to be familiar now. Down 251 cubic centimeters compared to Mopar's normally aspirated SRT engine, it's a 6.2-liter V-8 capped with a 2.4-liter IHI supercharger that stuffs the Hellcat's 8 cyndrical tubes with 11.6 psi of increase to generate such jaw-dropping result. In the Trackhawk, it makes its complete enhance of horse power yet sheds 5 lb-ft of torque compared to the cars and truck applications-- to 645-- due to a much more limiting exhaust system.

Caught up in a sledgehammer fight against the supercharged V-8, designers used the very same blunt-force attitude to the remainder of the powertrain: There's a beefier transmission and also a stouter transfer instance, and the back driveshaft, half-shafts, Curriculum Vitae joints, and also differential are strengthened. The front axle is unchanged from the regular SRT Jeep. That transmission is still a ZF-supplied eight-speed automatic, now christened 8HP95 and also formally ranked to take care of up to 811 lb-ft. The transfer situation courses torque forward with a larger chain than in the naturally aspirated SRT, with forged-steel gears instead of powdered-metal ones. Tube-wall density is up on the back driveshaft, while the differential housing gains a mount, going from three to four. Inside, the diff itself goes from two spider gears to four, with modified tooth geometry for better toughness. The Hellcat engine alone exceeds its naturally aspirated bro by 108 extra pounds, and the bigger-hammer spec increases the Trackhawk an added 105 extra pounds overall above the Grand Cherokee SRT, according to Jeep.

Like the Challenger SRT Satanic force, the Trackhawk gets a Torque Reserve feature to assist introducing. With launch control turned on, this system cuts gas to individual cylinders while the Jeep is brake-torqued, permitting the engine to rev higher and the supercharger to construct even more boost. With the feature engaged, the blower produces 6.4 psi while resting at the line. Just what the Trackhawk doesn't get is any more tire than the Grand Cherokee SRT. Raise your foot off the brake as well as the Trackhawk will certainly screech all 4 295/45ZR -20 Pirellis (either all-season Scorpion Verdes or a lot more aggressive P Absolutely nos) on its way to exactly what Jeep claims is a 3.5-second zero-to-60-mph time. The company says the Trackhawk will melt with the quarter-mile in 11.6 seconds, however offered our recent failure to match SRT's efficiency cases, we suspect that number might likewise be contemporary of reach. Provide or take a couple of tenths, though, Club Motorsports' 14 percent quality really felt as flat as Google Maps' 2D view (where, incidentally, the track still shows up as dust as of this writing-- we informed you it was brand-new). Our one grievance concerning the engine is that we want much more blower whine when the accelerator is matted. There's a good little bit under lighter lots, yet at full throttle, it fades behind a raving gargle blaster of an exhaust roar so fierce it sounds like the tailpipes are clearing right into the cabin. (" The call is originating from inside your home!").

Barreling down Club Motorsports' hillsides stresses the rest of the Trackhawk's skill set. It retains the SRT's control-arm front and also multilink rear suspension layout, however the springs are 9 percent stiffer in advance as well as 15 percent stiffer out back. Not remarkably for something so hefty as well as with a lot rubber at each edge, it's fairly secure-- a preferable characteristic on a course with lots of camber differences. Yet toe into the brake and it'll revolve-- or lay into the brake and it'll dance disconcertingly, even in a straight line. The steering is a touch slow-moving however heavy enough for perceptible weight to hemorrhage off as the nose starts to rinse. Although the brakes always really felt strong, pedal traveling enhanced to a disconcerting level over the course of our splashing session.

At 15.7 inches in size, the Trackhawk's two-piece (light weight aluminum hat and also iron rubbing surface area) front blades are 0.8 inch larger than those on the normally aspirated SRT Jeep. The 13.8-inch rears coincide, as are the six-piston front as well as four-piston rear calipers, but the Trackhawk's pinchers obtain a coat of yellow paint. Jeep hopes you like it, due to the fact that it's exactly what you get regardless of exterior color or whether you go with the basic aluminum-finish or optional satin-black wheels. The latter are three pounds lighter each edge.

Those yellow calipers are just one of the Trackhawk's couple of exterior tells. Others consist of the deleted fog lights, their nests burrowed for an oil colder on the guest's side and also a cold-air consumption on the chauffeur's side. A new back fascia suits the quad exhaust outlets. There's a refined "Trackhawk" badge on the reduced right edge of the liftgate and "supercharged" script below the usual Grand Cherokee lettering on the front doors.

Inside, there are Trackhawk logo designs on the seats, a Trackhawk-exclusive red-and-black two-tone inside option, as well as a 200-mph speedometer. That's positive by just 20 ticks, according to Jeep, but by its orientation the speedo constantly minimizes your speed: 0 is straight down, 200 is straight up, and at 100 miles per hour, the needle factors horizontal. To the majority of us, a declined tip is requesting more mph, but this set only starts to close on level at extralegal speeds.
The rest of the inside is conventional Grand Cherokee SRT fare: roomy, with comfy seatsing front and also back and a substantial freight hold. There's a factor the Grand Cherokee is just one of the very successful SUVs in the nation, as well as those 200,000 approximately yearly customers aren't making a bad choice. While the Trackhawk's stiffer ride is obvious on New England's rough country two-lanes, it's not so rough about be an exit ramp. Better not try to switch off those roadways, though, because while the Trackhawk is a Jeep, its method and also departure angles are extra like those of a Toyota Camry.

Yet the Trackhawk does offset its 707-hp breeding telephone call with an inescapable excrescence: its $86,995 base cost. That's $17,905 greater than you'll pay to get a Hellcat engine in a Charger as well as $20,405 greater than it sets you back in a Challenger. The Trackhawk is really nearly as fast as either of those, and also it's far more drivable. Plus, it'll tow 7200 extra pounds, enough to let you bring the Hellcat of your option along on a trailer-- even if it's a spare Trackhawk. The problem comes when you begin including choices and also take a look at likewise priced performance SUVs. It's not hard to top $100,000 with a Trackhawk. No, the BMW X5 M and also the Mercedes-AMG GLE63 do not have horse power ratings starting with lucky number 7, yet they're in the exact same performance ball park and provide more polish and also higher-- if completely various-- stature. Unless, obviously, a purchaser just wants the Hellcat mania in a manageable plan. Since it's an awful lot of enjoyable opposing physics in this Jeep.
