The U.S. auto industry is likely to set a record for industry sales in 2016, before declining slightly next year in part due to bloated inventory that is already beginning to impact Detroit Three production, according to one forecasting firm. IHS Markit predicts the U.S. auto industry will sell a record number of vehicles this year, surpassing 2015’s record of 17.47 million sold. For 2017, it is lowering forecasts to 17.37 million from an earlier predicted 17.5 million in part because of rising inventories and automakers’ use of incentives.
