Ram unveiled the 1500 Rumble Bee SRT less than three months ago, but Hennessey is already working on a more extreme variant known as the Maximus. That’s an apt name as it blows virtually everything else out of the water.

 

Previewed at the SRT Performance Engineering Day in Detroit, the truck has been equipped with an upgraded 6.2-liter V8, a high-capacity intercooler, a larger intake tube, and a proprietary engine calibration. Thanks to these changes, the Supercharged Maximus Rumble Bee SRT produces a staggering 1,032 hp (770 kW / 1,046 PS) and 947 lb-ft (1,283 Nm) of torque. That’s an increase of 255 hp (190 kW / 259 PS) and 267 lb-ft (362 Nm).
