I'm exaggerating. These models actually exist and aren't technically vapourware.
That said, for the Lyriq, they've indeed built thousands, but how many have actually been delivered? A few hundred? A local Cadillac dealer tells me he's has zero delivered and that an order today is not likely to be filled in less than 3 years! As for the Hummer, I understand they never intended to sell large numbers, but since its launch in late 2021, GM has built less than 1,000!
Customer deliveries of the GMC Hummer EV Pickup almost stalled in Q1 2023, reaching just two units. A year ago it was 99. The company promises an increase.
