The Least and Most Popular Car Models in America in 2020

The U.S. new car market in 2020 contracted almost 16 percent compared with the previous year, the most notable unit sale slump in more than a decade.

While only a minority of car models improved their year-on-year sales, there were still clear winners and losers on the car showroom forecourts.

New-vehicle inventory to sales data is a useful metric in gauging how vehicle models have performed against manufacturers' expectations. The longer a vehicle remains on the lot, the more likely the manufacturer overestimated how popular it was going to be.

Pickup trucks, SUVs, crossovers, and electric vehicles were the year's fastest sellers, according to Mark Strand, industry intelligence director for Cox Automotive—the company which used the data to compile the list below.

"Luxury and sports cars moved quickly post lockdowns, helped by the stock market surge," he said. "Slower sellers tended to be sedans, particularly subcompacts."

Take a look at the most and least popular car models of last year, according to time spent on inventory prior to selling.
