Since ruling Americas roads in the heyday of the US auto industry, sales of large sedans (as a percentage of the overall market) have been in a decades-long slump. More recently, as SUVs have merged with large cars to form the modern crossover, the decline in large car sales has picked up speed. And there’s reason to expect that trend to continue, as a closer look at the data shows that market support for large sedans has eroded farther than even these numbers might suggest. One of TTAC’s well-placed sources reveals that the “large car” segment (admittedly, a notoriously difficult segment to accurately capture) is running at 50% fleet sales, year-to-date through October. That’s right, every second large sedan sold in this country end up as a fleet vehicle, many of them daily rentals.
