The Detroit-based manufacturer lost its crown to Japanese rival Toyota Motor Corp., which boosted sales 10% last year despite a 28% decline in the fourth quarter. With 2.3 million units sold in the U.S. in 2021, Toyota narrowly outpaced GM’s 2.2 million.

The change at the top reflects the volatility of a year many carmakers will be happy to leave behind. From snarled shipping lines to semiconductor shortages, the challenges of 2021 left manufacturers struggling to keep up with demand. While industrywide sales likely rose modestly from 2020, supply constraints shattered any hope of a quick recovery from the early pandemic slump.

Carmakers likely sold a seasonally adjusted annual rate of about 12.5 million new vehicles in December, down 23% from a year earlier, according to the average forecast of six market researchers surveyed by Bloomberg. 

The extent of the issues became more clear on Tuesday as most major automakers reported U.S. sales for the fourth quarter and full year. Ford Motor Co. is expected to release its figures Wednesday.

For the full year, auto sales likely came to 14.9 million vehicles, a 2.5% jump from the coronavirus-stricken days of 2020, according to Cox Automotive. 

The year wasn’t without its bright spots. The inventory challenges helped push some buyers to more-profitable, option-laden models, while the mainstream embrace of electric vehicles accelerated. Indeed, Tesla Inc. on Sunday blew past Wall Street’s expectations with record quarterly global deliveries.

Other automakers will be hard-pressed to match that kind of performance. We’ll take a look at the results as the major manufacturers report throughout the day.

GM loses ground

GM’s sales for the year declined 13%, weighed down by a 43% plunge in the final quarter. Chevy Silverado sales fell more than 30% and GMC Sierra sales tumbled 21% in the quarter. The auto giant was quick to blame chip constraints for its woes, saying they put a 13% drag on sales.

That forced GM to be strategic about where it dedicated supplies. In a dismal quarter, sales of the Chevy Tahoe and Suburban, GMC Yukon and Cadillac Escalade large sport utility vehicles all were up. Those are the most profitable vehicles the company sells.

Crucially for investors, GM said semiconductor supplies got better toward year-end, and the company forecast further improvements in 2022.

Toyota takes over

Toyota’s strong 2021 performance was buoyed by sales of sedans such as the Corolla and Camry. While the automaker’s top-selling vehicle remained the RAV4, the compact SUV’s sales actually dropped 5% for the year. Sales of the Corolla and Camry rose 5% and 6.6%, respectively.

While final tallies for the industry are still to come, Toyota likely gained one point of market share in the fourth quarter, giving it 15.5% of sales and the top spot. It’s the first time GM hasn’t been No. 1 since 1931, when it beat out Ford.

Hyundai’s cheap chic

[hotlink]Hyundai Motor[/hotlink] Co.’s namesake brand was one of the big winners last year, logging a 19% increase in sales from a year earlier. The Korean automaker did lose some steam in the waning months of 2021, however, with a 15% drop in fourth-quarter deliveries to 152,446 vehicles. For the month of December alone, its sales fell 23%.

U.S. retail sales were the company’s highest ever, buoyed by demand for the budget-friendly Venue subcompact crossover model, which starts at less than $20,000, as well as for the Kona subcompact SUV and Tucson compact SUV.
