27. 1932 Ford
Even though the â32 Ford was just a regular, mass-produced, everyday car, it changed automotive history forever. It became one of the most influential American machines due to a rather simple engine option: the Flathead V8, one of the best engines of the 20th century. It was Ford’s simple-but-effective 3.6-liter V8 engine producing just 65 HP at the beginning of the production.

Even though other carmakers offered V8 engines in their models, Ford’s design proved to be the best. Soon it became the definitive engine for anybody looking for power in an affordable package. Hot rodders learned the Flathead V8 had serious tuning potential, so all â32 Fords became the favorite base for all kinds of modifications. The â32 Ford with the infamous Flathead V8 engine was one of the most revolutionary American cars since it introduced V8 power to a larger market. In fact, it established the V8 engine as one of the most recognizable features of the U.S. car industry.
