REO Speedwagon (originally stylized as R.E.O. Speedwagon)
The members returned to school in the fall of 1967 and had their first rehearsal before classes started. They named the band REO Speedwagon, from the REO Speed Wagon, a 1915 truck that was designed by Ransom Eli Olds.[3] Doughty had seen the name written across the blackboard when he walked into his History of Transportation class on the first day they had decided to look for a name. Rather than pronouncing REO as a single word as the motor company did ("REE-oh"), they chose to spell the word out, pronouncing each letter individually ("R-E-O").
