Unless you have been living under a rock somewhere, I am sure you have heard of the coming of the 2018 Dodge Challenger SRT Demon, with 840 horsepower and a sub-10 second ¼ mile time! However, showroom Demons make 808 ponies on premium fuel, an increase of 101 over the Hellcat. To unlock the 840 in the Demon, buyers must also purchase the Demon Crate. Cost is TBD, but SRT leader Kuniskis hopes it will cost $1. In the crate are some skinny front wheels, all the snap-on tools needed to change tires at the track, a new engine ECU, a new air filter, a low-temperature thermostat, a cover plate to facilitate removing the passenger-side mirror, and a new HVAC switch module with an extra button on it. That button, a gas-pump silhouette with “HO” in the middle, activates a high-octane engine map (hence the ECU and air filter), increasing power to 840 hp and torque to 770 lb-ft at 4500 rpm, up from 717. Kuniskis says the Demon is emissions compliant no matter what mode it’s running. All the tools and the “runners,” as the skinny wheels are called, fit in a molded piece of foam that stows nicely in the trunk and is easily removed in the paddock. The one you may not have heard about is the 2018 Jeep Grand Cherokee Trackhawk, which just may be the most powerful SUV in the world with its Hellcat inspired 707 horsepower. With AWD giving it more traction than the Hellcat, Jeep claims it can reach 60 mph in 3.5 seconds.
The supercharged 6.2-liter Hemi V-8 is mostly left alone, right down to its forged pistons, sodium-filled exhaust valves, heavy-duty bearings, and blower pushing up to 11.6 psi. Is the world ready for a 707 horsepower Jeep? Was it ready for a 485 horsepower Jeep when the SRT came out? No one really thought so, but they have earned quite the following, and I am sure the same will happen with the Trackhawk.
