Truck rockets from 0-60 mph in 3.0 seconds and has a top speed of 200 mph. 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. 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. This means the Maximus is four tenths of a second faster to 60 mph (96 km/h) than the Rumble Bee SRT and has a 30 mph (48 km/h) higher top speed.
