The original prototype's failure to achieve Japanese market homologation led to the development of the Dome Zero P2 prototype, a car made specifically for export and sale in countries such as the United States. At the time, it was relatively simple for Japanese buyers to obtain "export only" vehicles via grey market re-imports. Hayashi believed this would also allow sales to the Japanese market without regulatory approval.
The P2 had large front and rear bumpers added (for the US market) and various other structural modifications that altered the car's appearance. The P2 used the same Nissan L28E engine as the first prototype, but the press reported that turbocharged Nissan or Toyota straight-6 engines were being considered for production cars. The car was shown at the Chicago and Los Angeles motor shows in 1979 and was positively reviewed by Road & Track magazine.
When introduced, the Dome Zero P2 was estimated to have a retail price between US$30,000 to US$60,000. Efforts to homologate the P2 for sale in Japan and overseas failed, and it was never produced for commercial sale.
