Chapters: 00:00 Why GM’s all-electric future is a big gamble (Published September 2021) 15:17 The rise of electric boats (Published April 2022) 27:13 Why GM says its Ultium platform will drive EV dominance (Published May 2022)

The automaker made its name selling gas burning cars but in January 2021, it made a stunning announcement. The company said it “aspires to eliminate tailpipe emissions from new light-duty vehicles by 2035.” This means that GM intends to stop selling gas-burning cars. General Motors says it wants to lead electric vehicle sales in North America by 2025, and vows that its new Ultium battery platform will drive that dominance.

Not only are cars going electric but so are boats. General Motors recently invested $150 million in one start-up, Pure Watercraft, to build an electric pontoon boat. And several others are working to bring their own battery-powered offerings to market. CNBC Marathon brings together the best of CNBC on YouTube.
