Rumors have been swirling, and earlier this month we talked about the Grand Cherokee Trackhawk receiving the Hellcat powertrain. Our sources have confirmed that it’s coming, and have also confirmed some details.

It’s called Project K, and Fiat Chrysler Automobiles [NYSE:FCAU] doesn’t want you to know it’s been given the green light for production. Not only has it been approved, but mules are testing the powertrain using 2016 Grand Cherokee bodies.

When it hits the streets, the Hellcat-powered Jeep will be a 2017 model year.

Sources say the Trackhawk will feature the same supercharged 6.2-liter HEMI V-8 as other Hellcats, and output should remain about 707 horsepower. A ZF eight-speed automatic transmission will handle shifting duties, and all-wheel drive will be standard. Whether torque is limited to preserve the all-wheel-drive system or not has yet to be confirmed.

Performance should be nothing short of breathtaking. Our source says the HellJeep will be capable of an estimated top speed of 200 mph and should run the 0-60 mph dash in under 3. Thank the standard all-wheel drive for the insane acceleration.

We reached out to Fiat Chrysler Automobiles to ask about Project K and the Grand Cherokee Trackhawk/Hellcat. A spokesperson would only say, “We don’t comment on future products.”

Think a Hellcatted Grand Cherokee is just overkill for hauling the boat on the weekend? Our source also told us the Grand Cherokee SRT together with a name change would receive a power increase from its 6.4-liter HEMI V-8 to an estimated 490 horsepower.

We’ll bring you more information as it becomes available.
