The first vehicle built by the automotive division of Fuji Heavy Industries was called the Subaru 1500, with the development code-name of P1. The prototype used a monocoque body structure, with an independent front wishbone suspension and a rear leaf spring suspension with three plates and a live rear axle.
The 1.5 litre four-cylinder OHV engine, code named "FG4A" was sourced from Peugeot from the Peugeot 202, and built by Fuji Precision Technology, later known as the Prince Motor Company. The FG4A engine was related to the Prince GA4 with some modification. The 1500 has a similar appearance to the Peugeot 404. Later a different engine was developed in-house by Fuji Heavy Industries, code named "L4-1" which was also a 1.5 litre OHV engine, that was 20 percent lighter than the previous engine used. The "P-1" was water-cooled and used an four-cylinder inline engine.
Only 20 "P-1"'s were built, with 11 vehicles using the "FG4A" engine. Six units were provided to the Isesaki Ota Honjo taxi company for private testing, with successful results.
It was Subaru's first (and until the introduction of the BRZ in 2012, only) FR vehicle.
