General Motors’ sales during 2021 fell more than those of any other automaker. GM also suffered the ignominy of ceding its top selling position for the first time in more than 80 years, as Toyota outsold GM for the first time ever. In other changes of fortune, Hyundai sold more than Honda, and Tesla was the fastest-growing OEM. SUVs reached a record 55% share in 2021, according the respected LMC Automotive consultancy.
