Is the Volt.
Tesla’s Model S, priced at $69,900, likely sold around 8,931 units, but does not report sales on a monthly basis. The estimate reveals the possibility that Tesla has been overtaken in the first half volume lead after leading in the first quarter. GM’s Volt, which gets about 38 miles on battery power before gasoline is used, had a 12 percent increase to 9,855 units in the first half. Nissan Motor’s Leaf sold 9,839 units putting it just behind the Volt.
