Last October, we reported on Chrysler trademarking the 'Trackhawk' name. The assumption at the time was Jeep would use their on their high-performance Grand Cherokee as Dodge laid claim to the SRT name.
Now Car and Driver has some new information concerning the Trackhawk. The name is expected to arrive sometime in 2016 with the choice of two engines. The base will be the 6.4L HEMI V8 with 475 horsepower currently found in the Grand Cherokee SRT. Optional is the 6.2L Supercharged Hellcat V8 with 707 horsepower. Now this engine is giving engineers some problems as the driveline can't handle the Hellcat's torque. It could mean Jeep could scrap the four-wheel drive system and go with two-wheel drive, or limit the amount of torque available in lower gears.
