The Ford F-150 Street was a concept car built in 1990.
The Street was an exercise that went head-to-head with California customs in creating a mean and nasty street image. Based on a full-size F-150 model, the Street gets its stance from a low profile and big 16 inch wheels. The roof height was chopped 3 1/2 inches from the production F-150. The truck is lowered 4 inches at at front and 3 inches at the rear. The suspension was set up to create a nose-down "bad" attitude street-look.
The California influence is also evident in the shaved door handles, frenched antenna and quad exhaust molded into the rocker panels. Ford didn't place anything special under the hood to back up the menacing look.
