No one who has driven a Jeep Grand Cherokee Trackhawk has climbed out of the hot seat and thought ‘Gee, this thing really needs more power!’.
With a supercharged 6.2-litre Hemi V8 lifted from the Dodge Charger and Challenger Hellcat twins sending 522kW and 868Nm to all four wheels, the Trackhawk is a masterclass in American excess.
Thing is, parent company Fiat Chrysler Automobiles could be cooking up something even more extreme.
Spy shots taken near one of FCA’s testing facilities hint at a Grand Cherokee with the frankly ridiculous engine from the Dodge Demon slotted behind its snout.
The Dodge Demon has the same size 6.2-litre V8 block as the Trackhawk/Hellcat models, but with a larger supercharger ensuring it makes 603kW and 972Nm on ‘regular’ premium fuel, with power levels stepping up to 626kW and 1040Nm with 100RON octane juice.
The tip-off that this is a bigger, badder Grand Cherokee is the bonnet. While the ‘regular’ Trackhawk has some subtle bonnet cut-outs, the spy shots show a Jeep with a much larger bonnet bulge and air scoop, mimicking that of the Demon.
Even if the more powerful 626kW tune isn’t available for the Grand Cherokee Demon, 606kW and 972Nm is a hell of a lot of power to push through an all-wheel-drive transmission.
With ‘just’ 522kW, the Trackhawk is capable of cracking 100km/h in 3.7 seconds when independently performance tested by our sister mag, Motor.
The Challenger Demon is not available from the factory in Australia, however private companies are importing and converting the strip weapon for a princely sum of approximately $300,000.
If the harder Grand Cherokee is built, Australian customers would surely be lining up around the block to get their hands on it.
Currently, the next most powerful purely combustion-powered SUV after the Trackhawk is the Lamborghini Urus, with 478W from a VW-family twin-turbocharged 4.0-litre V8. The hybrid Porsche Cayenne Turbo S E-Hybrid has 500kW by combining the same engine of the Urus, with a battery and electric motor.
The Jeep Grand Cherokee is getting long in the tooth, and a replacement has been on the cards for some time. A 626kW farewell would be fitting for the V8 SUV icon.
