The name Porsche is commonly mispronounced here in the United States, for whatever reason. The company, which was originally known in 1931 under the name "Dr. Ing. h. c. F. Porsche GmbH," is named after its founder Ferdinand Porsche. The Porsche family (along with the related Piëch family) is still heavily involved in the company that bears their name.
