When is 707 greater than 840? And when is an SUV faster than a drag car? Pretty much only when a Jeep Trackhawk takes on a Dodge Demon. Unbelievable, right? Well believe it. The 707 horsepower, seven passenger Trackhawk SUV has a top speed of 180, while the 840 horse Demon only has a top speed of 168.
The physics involved here don't clear anything up. The heavier, less powerful, less aerodynamic vehicle should not have a higher top speed. It doesn't make sense.

Until you consider the tires.

Now it all makes sense. In order to get unreal acceleration and the front tires off the ground at the strip, a very sticky, somehow street legal drag tire has to be used on the Demon, and those specialty tires are rated to, surprise, 168 mph.
Obviously a manufacturer cannot allow the car to travel faster than its stock tires can handle, so they limit the car to its top speed of "only" 168. Take a Demon, slap on different tires and remove the limiter, and the Trackhawk loses its advantage. And all is right in the world again. Sir Newton was worried there for a second.
