SAAB Quantum was a series of five privately designed and built automobiles using various Saab components. The earliest used Saab 93 two-stroke engines, transmissions and suspension. The later used Saab 96 drivetrains and suspension parts. All were built in the United States. The Quantum III was designed to be a production car and was first presented in 1962. Only a few copies were built. Due to a lack of quality it was turned down by Saab in Sweden and never went into production. Saab Quantum IV rear * Saab Quantum IV front * Saab Quantum IV side *
