The model range was launched 40 years ago to replace the already legendary BMW 02, and is now set to enter its sixth generation. Today, as in 1975, purchasing a BMW 3 Series represents an expression of joy in sporty, agile handling, enthusiasm for innovative technology and appreciation of premium quality.

First unveiled at the 1975 International Motor Show (IAA) in Frankfurt, the BMW 3 Series has since developed into both the brand’s most successful model range and an international bestseller. And that makes the 3 Series a highly effective global ambassador for BMW’s core attributes.

In 1977, two years after the launch of the new model range, the BMW 3 Series became the first car in its class to be available with six-cylinder engines. Further innovations were to follow, including revolutionary injection and engine management systems, ultra-sporty diesel engines and weight minimisation through the use of aluminium and magnesium.

A four-door body variant joined the two-door model in the range back in the second generation, and it wasn’t long before the BMW M3 high-performance sports car, the first Touring model and the first Convertible based on the BMW 3 Series were given their premieres. The third generation of the model range saw the distinctively styled BMW 3 Series Coupe bring additional allure to the line-up, while the BMW 3 Series Compact forged a passage into a new vehicle segment.

The sixth model generation further extends this attractive selection of distinctive body variants, which are now split between two model ranges: the BMW 3 Series Sedan and BMW 3 Series Touring have been joined by the BMW 3 Series Gran Turismo, and the mid-size model portfolio now also includes the BMW 4 Series Coupe, BMW 4 Series Convertible and BMW 4 Series Gran Coupe.
