The early Bugatti 8-cylinder line began with the 1922 Type 30. The same basic design was used for the 1926 Type 38 as well as the Type 40, Type 43, Type 44, and Type 49.

Type 30

Produced from 1922 through 1936, the Type 30 used the 2991 cc engine of the Type 29 racer.

Type 38

The Type 38 was produced in 1926 and 1927. It also used the 2991 cc engine.

Type 40

The Type 40, introduced in 1926 and produced through 1930, used the 3-valve 1496 cc engine first used in the Type 37 . About 800 were built.

Type 43

Another evolution of the basic 8 platform, the Type 43 borrowed the 2262 cc engine from the Type 35B .

Type 44

The Type 44 was the widest-production variant of this range, with 1,095 known. It used a new 3-valve SOHC 2991 cc engine derived from the Type 43's unit. It was built from 1927 through 1931.

Type 49

The Bugatti Type 49 was produced from 1930 through 1932. The Type 49 was the last of the early 8-cylinder Bugatti line which began with the Type 30. Just 49 examples were built.

The Type 49 featured a straight-8 engine of 3257 cc displacement. Bore and stroke were 72 mm bu 100 mm and three valves per cylinder were used with a single overhead camshaft.
