GMC sales and premium-trim statistics

GM describes the figure as more than 2 million and does not provide the exact total on the page.

This is a GM-reported retail-sales share, not an independently audited market estimate.

The figure is the announced production limit, not reported completed deliveries.

The underlying percentages are internal GM sales figures; the combined figure is a direct arithmetic sum of the two reported shares.

GMC model sales history

The delivery release reports GMC brand deliveries; it is not a current-period sales measure.

The release’s model table is historical and does not represent current Sierra sales.

The release’s model table is historical and does not represent current Terrain sales.

GMC fuel economy and vehicle-market context

  • Average model-year 2024 new-vehicle real-world fuel economy reached a record 27.2 mpg, up 0.1 mpg from model year 2023 (Model year 2024 versus 2023; United States new-vehicle fleet). (Highlights of the Automotive Trends Report)
  • In model year 2024, 66% of all new vehicles were trucks under NHTSA regulatory definitions, while truck SUVs accounted for half of all new-vehicle production. (Highlights of the Automotive Trends Report)
  • Truck-SUV fuel economy increased by 1.0 mpg to 25.7 mpg in model year 2024 compared with model year 2023 (Model year 2024 versus 2023; United States truck-SUV market). (Highlights of the Automotive Trends Report)
  • The EPA estimated GM’s model-year 2024 new-vehicle fleet at 22.9 mpg, the second-lowest value among the large manufacturers listed after Stellantis at 22.8 mpg (Model year 2024; United States GM new-vehicle fleet). (Highlights of the Automotive Trends Report)

EPA labels these as estimated real-world fleet values; they describe the overall U.S. fleet, not GMC alone.

The truck classification follows NHTSA regulatory definitions; the figures describe the overall U.S. market, not GMC production.

This is an EPA vehicle-type estimate and is not a GMC-specific fleet statistic.

The value is manufacturer-fleet estimated real-world fuel economy and includes GM vehicles beyond the GMC brand.

GMC safety-test statistics

  • In IIHS testing of the 2024 GMC Sierra 1500 pedestrian front-crash-prevention system, impact speed was reduced by 4 mph in the 12-mph crossing-child daytime test and by 11 mph in the 25-mph crossing-child daytime test (2024 vehicle rating and test cycle; IIHS test track, United States rating program). (2024 GMC Sierra 1500)
  • In IIHS testing of the 2024 GMC Sierra 1500, the pedestrian front-crash-prevention system reduced impact speed by 23 mph in the 25-mph crossing-adult night test with low beams and by 26 mph in the 37-mph parallel-adult night test with high beams (2024 vehicle rating and test cycle; IIHS test track, United States rating program). (2024 GMC Sierra 1500)

These are controlled IIHS test results for the tested Sierra configuration and should not be interpreted as real-world crash outcomes.
