You don't really need an aircraft motor to have a dangerously fast car: "The Tatra 87 was praised by German officers in World War II for the superior speed and handling it offered for use on the Autobahn. The Nazi armaments and munitions minister Fritz Todt declared: "This 87 is the Autobahn car ..." It was known, however, as the 'Czech secret weapon' because it killed so many Nazi officers during World War II that the German Army eventually forbade its officers from driving the Tatra." <https://en.wikipedia.org/wiki/Tatra_87>
