The last generation Jeep Grand Cherokee SRT8 was always one of our favorite high-performance SUVs and its 6.1-liter Hemi V8 lunacy never failed to delight. Thankfully, with the brand-new Grand Cherokee now entering showrooms, a new SRT8 is apparently on the way as well.

A low-riding, big-tired, deep-chinned Jeep has been spotted out testing with a trailer, and it looks to be the SRT8 successor. The new model will likely be powered by an upgraded Hemi that's punched out to 6.4-liters with an output boosted to 480 horsepower and 460 pound-feet of torque.

The prototype dispenses with the central exhaust tips on the old model in favor of more typical outboard pipes, which at least makes it easier to rig up a tow hitch. While this could change back for production, the fact that the prototype is toting a trailer could be a sign that Jeep wants to improve its utility beyond the 3,500 pounds of the outgoing model.
