BMW's sport genes are well-known, and it is the 328 that sets the tone. There are three places in the museum (lightweight technology, classic design, convertible car exhibition area) where he can be imagined to be important. With BMW's famous in-line six-cylinder engine and then extremely innovative aluminum alloy body structure, 328 has won 120 Championships in more than 170 competitions in its short career, leaving a brilliant chapter in BMW's history and playing the name of sports luxury car for BMW. To commemorate this legendary classic model, BMW launched two concept cars, 328 Mille Miglia Coupe and 328 Hommage, in 2010 and 2011, respectively, to pay tribute. The 501 was the first BMW car to start selling after the war, and two years later the 502, equipped with a V8 engine, was introduced to the market. The redesigned chassis and the use of advanced technology have made 501 the pioneer of redefining BMW luxury cars, and its extremely elegant shape has earned itself the reputation of "Baroque Angel" (although 335 Saloon is placed first on the third floor of the 7-series booth, but individuals prefer to rank second 502 as the real ancestor of the 7-series). Yes, as the demand for small-displacement cars seems to be greater in the shadow of the post-war era, 501/502 sales are not satisfactory and will soon enter history.
