General Motors proclaims its plans to include heat-pump know-how in all of its present and upcoming Ultium-platform electric autos.
That consists of the Hummer EV now being delivered and the soon-arriving Cadillac Lyriq, plus many more to reach within the next several years. In them, the tech will assist recover low-level waste heat in ways that may add up in significant methods – bringing them faster acceleration, quicker charging, and an extended vary

Confidential used a heat pump that was developed by GM engineers at the time. The automaker says the function is on the market on all current Ultium EVs, and will also be commonplace in all upcoming Ultium fashions.
