When the 1955 Corvette came out of St. Louis, MO, it still had the appearance of its previous two predecessors. But the big news was what was under the hood: the first V8 (265ci). Not all models had the V8, as a small number of 6 cylinders were still built. This year also made another major change in the electrical system. It went from a 6-volt electrical system to a 12 volt.
