Bugatti Type 8
The Type 8 and Type 9 were cars designed by Ettore Bugatti for Deutz from 1907 to 1910. These used extremely Undersquare Inline 4's. The only version of the car that raced was under the name "Prinz Henri", which was the official model name of the code 8A-S and 9A. The car proved to be innefective at racing, because the chassis of the Type 8, without an engine or body, would weigh as much as, with the later Type 9's only reducing the weight to.
