But the real significance of the two vehicles is pointed out by Tim Grewe, director of global battery cell and electrification strategy for GM. They are, he confirms, “the first vehicles” made by the company to use its new Ultium battery technology developed by GM in collaboration with Korean LG Energy Solution.

Grewe explains that the term ‘Ultium’ is quite broad in its application. “It is used for many things including the associated charging network that we call Ultium 360 and the cell manufacturing plant that has the name Ultium Cells,” he explains.
