Reports suggest that the current SRT model will be rebranded as the Jeep Grand Cherokee Trackhawk and may have the option of the supercharged Hellcat engine.

Late last year, Allpar reported that Fiat Chrysler (FCA) had trademarked the Trackhawk name. Just as the Trailhawk moniker is being used to specify off-roading versions of certain Jeep models, the Trackhawk badge would be used to denote performance-oriented Jeep models.

Given the company’s stated desire to reserve the SRT sub-brand for Dodge vehicles, at least in the US, the Trackhawk would be a like-for-like replacement for the current Grand Cherokee SRT. As such, it will likely feature the version of the 344kW/624Nm 6.4-litre V8 used in the current SRT (below).

Car and Driver believes that FCA is working on a version of the Grand Cherokee Trackhawk that will be powered by the Hellcat engine that’s currently doing service in the Dodge Challenger coupe and Charger sedan (below).

In both those vehicles, the 6.2-litre supercharged Hellcat V8 pumps out 527kW of power and 880Nm to the rear wheels via eight-speed automatic; a six-speed manual is also available for Challenger buyers.

A Hellcat-equipped Grand Cherokee is estimated to have a 0 to 60mph (96km/h) time of under four seconds. The current Grand Cherokee SRT takes 4.6 seconds to hit the 60mph mark.

The American magazine says that engineers at Fiat Chrysler are currently having problems getting the Grand Cherokee‘s all-wheel drive system to reliable cope with the Hellcat engine’s 880Nm of torque. This may entail Jeep either forgoing all-wheel drive or limiting torque output in certain gears.

There’s also another issue at the moment. The company can’t make enough Hellcat drivetrains to satisfy demand for the currently available Charger and Challenger. This has reportedly lead to the company closing the order book for both cars until around August 2015.
