The 40 cars lined up five to a row, except for the first and last. In the first row, the Stoddard-Dayton pace car was situated on the inside (driven by IMS owner Carl Fisher), with four competitors cars rounding out the row. Rows 2-8 had five cars each, while the final row had only one car in it. Fisher's use of the Stoddard-Dayton is believed to constitute the first use of such a vehicle, for the first known mass rolling start of an automobile race.
