At first BMW’s engineering director argued that the larger motor would not fit. But thankfully Helmut Werner Bönsch, BMW’s director of product planning, and Alex von Falkenhausen, designer of the M10 engine, each had had a two-liter engine installed in a 1602 for their respective personal use. Neither knew about the other until one day they found themselves, and their 2.0-liter 1602s, at the same BMW workshop having their personal cars serviced. Together Bönsch and von Falkenhausen created a proposal for the BMW Board to put a 2.0 liter version of the 1602 into production.
