Roush has been hopping up the Ford Mustang and the Ford line of trucks for a long time now. Of all the trucks that Roush builds up, the fastest are the Roush Nightmare F-150s. Roush modifies these trucks extensively, but the big modification is a supercharger that brings 650 horsepower to the F-150.
Roush took a pair of Nightmare F-150 trucks to the drag strip to see if they could set a record for the fastest accelerating production trucks. Two Nightmare models went to the track, one was a Ford F-150 Supercrew 4x4, and the other was a Ford F-150 regular cab 4x4.
Both of the trucks lined up and set about their acceleration runs. The four-door Supercrew 4x4 truck reached 60 mph in 4.1 seconds. The lighter 2-door regular cab truck hit 60 mph in 3.9 seconds. Roush said that both trucks are now the fastest acceleration production trucks out there.
