Originally GM promised the Debut Edition of the Lyriq for the first half of 2022, i.e. by June 30, Now they say it will be delivered in summer. Traditionally summer is considered finished by Labor Day, September 5, 67 days into the second half of 2022, though astronomers define summer as ending at the autumnal equinox, September 25, the 87th day of the second half. Which definition is GM using?
Summer ends in September. But Cadillac has already delivered Lyriq vehicles to the first buyers, so they fulfilled their promise. And the reservations for the 2024 model year are still open.
