“In model year 2022, hybrid vehicles reached a new high of 10% of all production. Strong and mild hybrid production grew, with mild hybrids accounting for 41% of overall hybrid production. The combined category of electric vehicles (EVs), plug-in hybrid vehicles (PHEVs), and fuel cell electric vehicles (FCVs) increased from 4% of production in model year 2021 to 7% of production in model year 2022 and are projected to reach 12% of production in model year 2023. This trend will likely continue as EV production is expected to grow across the industry in coming years.

“In model year 2022, the average estimated real-world CO2 emission rate for all new vehicles fell by 10 g/mi to 337 g/mi, the lowest ever measured. Real-world fuel economy increased by 0.6 mpg to a record high 26.0 mpg. This is the largest single year improvement in CO2 emission rates and fuel economy in nine years. Since model year 2004, CO2 emissions have decreased 27%, or 123 g/mi, and fuel economy has increased 35%, or 6.7 mpg. Over that time, CO2 emissions have improved in fifteen of eighteen years. (The trends in CO2 emissions and fuel economy since 1975 are shown in Figure ES-1) Preliminary data suggest that CO2 emissions and fuel economy in model year 2023 will improve from 2022.
