New GM sign

GM changed its sign on the Renaissance Center in Detroit on Jan. 11, 2021.

General Motors reported solid fourth-quarter and year-end results Wednesday despite an eight-week production shutdown caused by the COVID-19 pandemic and the impact of the Takata airbag-inflator recall announced in November.

GM's total market share rose to 18.32% compared with 17.09% in the year-earlier quarter, said Cox Automotive. It is the largest year-over-year gain in total U.S. market share since 1990.
