Twenty-five years after the original H2 rolled out in that unmistakable shade of yellow, GMC has pulled the same color back into the spotlight. The 2027 Hummer EV Icon 25 arrives as a tightly limited run of 250 trucks and SUVs, each wearing the new ICON Yellow paint and a serialized plaque that confirms its place in the short list. Production starts later this year at Factory Zero in Detroit, with the first examples expected in showrooms early in 2027 for buyers in the United States and Canada.
