The BMW 328 is a sports car made by BMW between 1936 and 1940, designed by Fritz Fiedler. It featured a tubular space frame and a hemispherical combustion chamber engine. It was much praised at the time for its performance and handling, proving to be suitable not only for the BMW factory drivers, but also perfect for everyday driving.

The car won many races, including the prestigious Mille Miglia � a class win in 1938 and the outright winner (with a streamlined body) in 1940. It also won the RAC Rally in 1939 and came in fifth overall (first in its class) in the 1939 Le Mans 24 hours.

The engine has hemispherical or cross flow combustion chambers. The intake valves are opened by the usual overhead valve push rod arrangement of a side cam, push rods, and rocker arms. The exhaust valves, on the other side of the cylinder head, are opened by the same cam shaft, vertical push rods, rocker arms, horizontal push rods, and a second set of rocker arms.

In 1999 the BMW 328 was named one of 25 finalists for Car of the Century by a worldwide panel of automotive journalists.
