Those things have to haul thousands of pounds, of course they are powerful.
On first glance, it would seem automatic that a Dodge Viper, would be able to easily beat a Peterbilt 379 Semi trailer. The power to size ratio would seemingly be in its favor. But looks can be deceiving. A Semi trailer has to be extremely powerful to pull such heavy loads. If you get rid of the trailer and add performance modifications, well you have an entirely different beast on your hands. Such as the Viper owner was soon to discover about his foe.
Apparently this Peterbilt 379 has a CAT c-15 that dishes out 2,500HP and can haul over 100,000 pounds. See what happens when the weight is dropped.
