In page Porsche 912:

"

In the early 1960s, Porsche planned to discontinue the Type 356, which would leave the newly introduced Type 911, with its more powerful six-cylinder powerplant, as the company's sole product. Concerned that the considerable price increase of the 911 over the 356 would cost the company sales and narrow its brand appeal, in 1963 Porsche executives decided to introduce a new four-cylinder entry-level model based on the 911. Like that vehicle with its internal factory designation of "901", the four-cylinder 912 was originally known at the company by a number with a zero in the middle, but the "902" designation was never used publicly.[1] ("912" as a project number was used after 1968 to indicate the 12 cylinder flat opposed engine developed for Porsche 917 racing car.[citation needed])
