If there’s one thing the Grand Cherokee Trackhawk does not lack, that is power. If, however, for whatever reason you feel the need for extra speed, then O.CT is one of the names to remember.
The tuner has reprogrammed the ECU of the 6.2-liter supercharged V8, upping its output to a whopping 819 PS (807 HP / 602 kW) and 950 Nm (701 lb-ft) of torque.
O.CT says that the Stage 1 upgrade will soon be joined by the Stage 2, which, aside from the modified ECU, will add a supercharger pulley kit and enhanced transmission software. The result will be even more amazing: 865 PS (853 hp / 636 kW) and a nice, round 1,000 Nm (736 lb-ft) of torque.

By comparison, the stock Grand Cherokee Trackhawk has to make do with “only” 716 PS (707 hp / 527 kW) and 873 Nm (645 lb-ft) of torque. Naught to 100 km/h (62 mph) takes 3.7 seconds and, if you find a long enough Autobahn, it’ll keep going up to 180 mph (289 km/h).
Mind you, as amazing as O.CT Tuning’s achievement may be, it pales next to what could very well be not only the most powerful Grand Cherokee Trackhawk out there, but the fast accelerating SUV the world has seen so far: Hennessey’s 1,200 hp (1,217 PS / 895 kW) and 1,000 lb-ft (1,355 Nm) masterpiece. Which, by the way, makes the Lamborghini Urus and Bentley Bentayga Speed seem irrelevant, as with 2.3 for the 0-60 mph (0-96 km/h) sprint and a 200+ mph (321 km/h) top speed, it is gunning for genuine supercars instead.
