SPIED: 2018 Jeep Grand Cherokee SRT Trackhawk Underbody Images
Beefed-up Components Help Harness Massive Supercharged Power
One bold photographer captured images of the Jeep Grand Cherokee SRT Trackhawk in a whole new light, snapping the super-SUV’s rear underbody and chassis components.
Predictably, just about everything on the Jeep has been beefed up, with stouter suspension components, a thick driveshaft, and what looks like some added bracing to stiffen the chassis. We also see axleshafts with some surface corrosion, but that could be a good thing, indicating Jeep is experimenting with components to see what works best, rather than replying on the units from the current SRT (which might not be stout enough for the Trackhawk’s power). Bilstein shock absorbers carry over from the regular SRT, but we wouldn’t be surprised if their tuning is altered.
The Jeep Grand Cherokee SRT Trackhawk will almost certainly be powered by a version of parent company Fiat Chrysler Automobiles’ SRT Hellcat engine, a supercharged 6.2L V-8 that produces 707 hp in the Dodge Charger and Challenger. For those keeping score at home, that represents a 232hp increase over what’s currently available in the Grand Cherokee SRT. Even if the Hellcat engine is retuned for less power and greater driveline reliability, it should still produce at least 200 hp more than the current SRT, and that will bode very well for performance.
It also predicates the need for those beefier driveline bits. All that added power and twist will certainly take its toll on the driveshaft, differentials, and drive axles, and Fiat Chrysler learned lessons on the Dodge Hellcat programs to help educate Jeep engineers on best practices. Jeep promised us a Grand Cherokee Hellcat by the end of 2017, so we won’t have to wait too long to find out what specific changes the company made.
