The Porsche Automobile Company is a German auto manufacturer based in Stuttgart, Baden-Württemberg, founded in 1931 by Ferdinand Porsche, with a focus on high-performance sports cars, SUVs, and sedans. The Free People's State of Württemberg, which had Stuttgart as its capital, was the inspiration for the Porsche logo.
Stuttgart's coat of arms depicts a black horse charging over a yellow backdrop, while the Württemberg coat of arms has antlers and red and black stripes. A font called 911 Porscha is very similar to the lettering under the shield of Porsche. You can download the font for free in the Fonts Used Section.
