The Cadillac Lyriq is one of the first vehicles to use GM’s Ultium platform. This drivetrain system now underpins all of its current and upcoming electric vehicles, other than the outgoing Chevy Bolt EV. After driving the Lyriq and liking it very much, I was interested in the precise details of the car’s pack and the larger Ultium system. So I interviewed Jerry Beemer, who leads GM’s EV Propulsion team. If you want to know everything about this system down to the individual cells, he’s your guy.
