The Porsche 989 is a 4-door performance-oriented touring sedan developed by Porsche between 1988 and 1991. The car was never produced, as development was halted in late 1991, and cancelled shortly after in January 1992.

The engine choice was initially planned as an 80 degree water-cooled V8. Early plans were for a 3.6-liter normally-aspirated version, but the final prototype featured a larger 4.2-liter V8.

The project was eventually canceled due to high costs, but its development laid the groundwork for the later Porsche Panamera sedan.
