U.S. light vehicle sales growth is expected by many industry experts to fall to low single digits in 2016. Growth is expected to slow as dealers are experiencing falling gross profit margins and manufacturers increasingly rely on incentives to boost sales. Many industry leaders believe 2016 is the beginning of a new phase for the automotive industry, where cost cutting is the priority, rather than capturing market share. A low unemployment environment with low fuel prices have undoubtedly buoyed auto sales, but a hawkish Federal Reserve in 2016 could spoil the fun. The auto industry reached a new milestone in 2015 as total light vehicle units sold reached 17.4 million. The growth in 2015 was solely attributable to the increase in truck and SUV unit sales, as this category grew 11.7 percent, while car unit sales fell 2.1 percent. Sales growth for trucks and SUVs has reached the low double digits in the last three years. Chart A shows total unit sales, segmented by type.
