In the fall of 1969 as the 1970 Pontiac models were introduced, Bill Knafel decided to introduce his own inexpensive, lightweight performance car. He was aware of the success of the Plymouth "Roadrunner", so he felt that by ordering the right combinations of options, he could market a successful performance car. He named it "Magnum 400" and sold about 50 that year. It started out as a Tempest coupe ordered with the 400 4BBL engine, Rally II wheels, the 1969 Judge stripe, and other choices of options to suit the customer's taste, such as 4 speed or turbohydramatic transmission, Safe-T-Track differential, and performance rear end ratios.
