Give or take 1/2 Million} If I did the math wrong, please correct me. Just pull out the calculator and divide 50 Billion by 40,000. It should give you a figure starting with 12 Million. Ok, that means Chevy needs to sell a million volts a month for a year, or 1/2 Million volts a month for two years, or about 300,000 volts a month for 3 years to pay back the 50 Billion. Well, one question, how many Volts have we sold so far?
