A persistent question shadowed all of the shiny new vehicles and highly-produced, glitzy debuts at the Detroit auto show this week: Where are the sedans?

Yahoo News reported that the middle-class sedan — as opposed to luxury brands and high-performance sports cars — is hard to find this week on the Detroit auto show’s floor, eclipsed by row upon row of giant trucks and SUVs.

“Car companies are acknowledging that the crossover, sport utility vehicle boom is continuing,” said analyst Michelle Krebs of AutoTrader.

Detroit’s Big Three automakers — Ford, General Motors and Fiat Chrysler — have gradually abandoned production of sedans for lack of profitability and lack of interest from consumers.

Sales of traditional cars are expected to plummet to 21.5% of the U.S. auto market by 2025, according to LMC Automotive. Last year, sedans and small cars accounted for 31.2% of new-vehicle sales — down from half only six years ago.

The abrupt tumble coincided with the revival of the U.S. auto industry, a drop in gas prices and a decade of economic recovery in the United States.

Consumers flocked to larger SUVs and trucks, which became more and more luxurious and comfortable and increasingly gas efficient.
