A BMW 12-cylinder at that time was sensational, and not without risk. Nobody could have anticipated then, how many German 12-cylinders were still to
follow. In terms of technology the challenges were not so big. Regarding the engine as a double 6-cylinder, there were, in principle, only the
cylinder block and the crankshaft as fully new parts. Many components could be taken from the shelve. For example, the pistons were identical with
those of the 1800, the complete injection system and ignition system were likewise taken over. Nevertheless, something completely new originated in
the eyes of the consumers, e.g. concerning sound and achievement. Of course, extensive labour was necessary in the remaining drive line. Also, the
chassis had to be adapted to the higher engine weight.
