The direct links to 43 Historical Posts covering 1946-2014 are below.
UPDATE 1: 2010 and 2011 rankings now feature Golf/Golf Plus/Jetta and Mini/Countryman splits.
UPDATE 2: There is now more data available between 1966 and 1971.
Historical Data for Germany running from 1946 to 2014 is now available. From 1979 onwards there is a Top 100 models ranking - yes that's 36 years up to today! And from 2005 to 2013 you can now see the split sales of the VW Golf and Golf Plus, a very rare piece of info you won't find anywhere else... You will find more detailed German data on any other website! This is the result of 3 full months of work and the generosity of Florian.
The West German market was dominated by the VW Beetle from 1946 to 1973, passing the 100,000 annual units for the first time in 1954, the 200,000 in 1959 and hitting its best-ever volume in 1961 at 348,929 units sold for a record 31.9% market share that year.
In 1974, the Mercedes Strich 8 took advantage of a wobbly passing of relay between the VW Beetle and Golf to finish the year in pole position with 140,127 sales. Then from 1975 to 1979 the new VW Golf established its leadership, peaking at 257,673 units in 1979, before Mercedes hit again in 1980, placing the W123 atop the German ranking with 202,253 sales.
VW Golf III
Since 1981, six generations of VW Golf have dominated the German models ranking. The second and third generation have been the most successful, with the Golf II peaking at 378,856 sales in 1987 and the Golf III establishing an all-time record of 414,132 units sold in a single year, 1992. The fifth gen was the weakest, dropping to 148,879 sales and 4.3% share in 2006.
There is much less info available for East Germany, only that the legendary Trabant and Wartburg dominated the roads for the good part of the 41 years of existence of the country.
Witness also the success of the Opel Rekord, the 2nd car to pass the 100,000 annual sales mark in Germany in 1959, the Opel Kadett, launched in 1962 and peaking at 261,308 sales for its very last year of existence in 1991, the VW Passat, the only other VW to pass the 200,000 annual sales mark (in 1991), Ford 17M, Audi 80, Opel Astra, the only nameplate to go beyond 300,000 sales in Germany for its first year in 1992, the BMW 3 Series, Mercedes C Class, Audi A4 and many more...
