GM vs MPLX Comparison

General Motors Co. emerged from the bankruptcy of General Motors Corp. (old GM) in July 2009. GM has eight brands and operates under three segments: GM North America, GM International, and GM Financial. The United States now has four brands instead of eight under old GM. The company regained its US market share leadership in 2022, after losing it to Toyota due to the chip shortage in 2021. 2024 US share was 17.0%. The Cruise autonomous vehicle arm, which GM now owns outright, previously operated driverless geofenced AV robotaxi services in San Francisco and other cities, but after a 2023 accident, GM decided that it will focus on personal AVs. GM Financial became the company's captive finance arm in 2010 via the purchase of AmeriCredit.
