Volvo trucks were used by Nascar and some team owners to haul their cars and
equipment from race to race during the racing season most likely because of fuel
efficiency. Nascar rules state only U.S. made cars can run in the races but the
team owners and Nascar staff uses foreign made haulers? In 2016 Nascar made,
"Mack Trucks" the official hauler of Nascar again most likely because they are
U.S. made but Mack Trucks is owned by the Swedish company, "Volvo".
