General Motors declares its plans to include heat-pump know-how in all of its current 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 arrive in the next several years. In them, the tech will assist recuperate low-level waste heat in ways that may add up in meaningful methods – bringing them quicker acceleration, faster charging, and an extended range
