Prewar
Type 10
The Bugatti automobile was prototyped as the Type 10 in Ettore Bugatti's basement in 1908 and 1909 while he was chief engineer at
Deutz Gasmotoren Fabrik in
Cologne, Germany.
The Type 10 used a

region, then still part of the
German Empire, looking for a factory to begin producing cars of his own. After World War I, Alsace became a part of France again, and with it Bugatti.
The car was preserved and nicknamed "''la baignoire''" ("the bathtub") by the staff at Molsheim in later years due to its shape. Ettore restored it in 1939 and repainted it an orange-red color, earning it a new nickname, "''le homard''" ("the lobster"). It was moved to

for the duration of World War II and remained there for decades before falling into private ownership. Today, the car is in California in the hands of a private collector.
Type 13
Upon starting operations at his new factory in
Molsheim, Bugatti refined his light
shaft-driven car into the Type 13 racer. This included boring the engine out to 65 mm for a total of 1.4 L (1368 cc/83 in
3). A major advance was the four-valve head Bugatti designed — one of the first of its type ever conceived. Power output with dual
Zenith carburetters reached 30 hp (22 kW) at 4500 rpm, more than adequate for the 660-lb (300-kg) car. Leaf springs were now fitted all around, and the car rode on a roughly 2-m (79-in) wheelbase. Although having the appearance of a toy, the Bugatti Type 13 was successfully raced. It was seen at hillclimbs as early as 1910 looking rather out of place compared to the bulky and brutish competition. What the Type 13 lacked in power, it made up in handling, steering, and braking. These important elements were retained throughout all future Bugatti designs. Top speed was at 125 km/h.
The new company produced five examples in 1910, and entered the

for the duration of the war, leaving the parts for three more buried near the factory. After the war, Bugatti returned, unearthed the parts, and prepared five Type 13s for racing.
Type 15
The Type 15 was a version of the Type 13 with a longer, 2400-mm (94.5-in), wheelbase. It had a six-sided radiator in front and semielliptical rear leaf springs.
Type 17
Another version, the Type 17, was also produced. This used a 2550-mm (100.4-in) wheelbase. It shared its hexagonal radiator and rear springs with the Type 15.
Type 22

The Type 15 was updated in 1913 as the Type 22. It had a larger roadgoing body, an oval radiator, and quarter-circle springs.
Type 23
This two-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.
Post-war
Type 13 Brescia
A Grand Prix for
Voiturettes at Le Mans was the only French event of 1920, and Bugatti entered the two completed cars from Milan and one more from the remaining parts. Ettore's illegal act of placing a hand on the radiator cap during the race brought disqualification to the leading car, however.
The Type 13 was unbeatable. Bugatti's cars finished in the top four places at the

in 1921, and orders poured in. Capitalizing on this victory, all subsequent four-valve Bugatti models bore the ''Brescia'' moniker.
These were the only Bugatti models to locate the carburettor on the left side of the engine and the exhaust on the right. Front-wheel brakes were added in 1926.
Type 23 Brescia Tourer

Bugatti capitalized on the racing success of the Type 13 "Brescia" with the full-production postwar Brescia Tourer. It used the multivalve Brescia engine, and 2,000 examples were built from 1920 through 1926, making it
the first full-production multivalve car ever made.
