The XP-41 was a modification of the last P-35 built (S/N 36-430). The aircraft's center fuselage was redesigned and had a much lower profile "greenhouse" canopy similar to the early P-47's. (Seversky was renamed Republic Aviation in October 1939 after Alexander Seversky left the company.) The XP-41 also had an R-1830 radial engine with a flush-mounted turbo-supercharger mounted in the belly with an air inlet port just forward of the left wing root. Finally, the aircraft discarded the P-35 landing gear partial aft retraction scheme in favor of a fully retracting inward landing gear.
