The Type 13 was the first real Bugatti car. Production of the Type 13 and later Types 15, 17, 22, and 23, began with the company's founding in 1910 and lasted through 1920 with 435 examples produced. Most road cars used an 8-valve engine, though five Type 13 racers had 16-valve heads, one of the first ever produced. The road cars became known as "pur-sang" ("thoroughbred") in keeping with Ettore Bugatti's feelings for his designs.
The car was brought back after World War I with multi-valve engines to bring fame to the marque at Brescia. The production "Brescia Tourer" also brought in much-needed cash.
Type 23
A 2-valve version of the Type 17 with a boat-tail body was built in 1913 as the Type 23. It also had the oval radiator of the Type 22.
Type 23 Brescia Tourer
Bugatti capitalized on the racing success of the Type 13 "Brescia" with the full-production post-war Brescia Tourer. It used the multi-valve Brescia engine, and 2,000 examples were built from 1920 through 1926, making it the first full-production multi-valve car ever made.
