Weight decreased within each of the vehicle types. These metrics are all at record highs, and horsepower, weight, and footprint are projected to increase again in model year 2021, as shown in Figure ES-3.īetween model year 20, fuel economy and footprint increased within each of the five vehicle types, and horsepower increased in four. Footprint has increased 4% since EPA began tracking it in model year 2008. Since model year 2004, the combination of technology innovation and market trends have resulted in average new vehicle fuel economy increasing 32%, horsepower increasing 17%, and weight increasing 1%. In the two decades prior to 2004, technology innovation and market trends generally resulted in increased vehicle power and weight (due to increasing vehicle size and content) while average new vehicle fuel economy steadily decreased and CO 2 emissions correspondingly increased. Production Share and Fuel Economy by Vehicle Type The trend away from sedan/wagons, which remain the vehicle type with the highest fuel economy and lowest CO 2 emissions, and towards vehicle types with lower fuel economy and higher CO 2 emissions has offset some of the fleetwide benefits that otherwise would have been achieved from the improvements within each vehicle type.įigure ES-2. Conversely, truck SUVs reached a record 39% of the market in model year 2020, and car SUVs reached a record 13% of the market. Sedans and wagons fell to 31% of the market, well below the 50% market share they held as recently as model year 2013, and far below the 80% market share they held in 1975. The overall new vehicle market continues to move away from the sedan/wagon vehicle type towards a combination of truck SUVs and car SUVs. Minivan/Vans, car SUVs, and sedan/wagons all increased fuel economy by 0.9 mpg, while truck SUVs increased by 0.3 mpg, and pickups increased by 0.2 mpg. All five vehicle types are at record high fuel economy and record low CO 2 emissions in model year 2020. The remaining 2WD SUVs are subject to car standards and classified as car SUVs. The distinction between car and truck SUVs is based on regulatory definitions where SUVs that are 4WD or above a weight threshold (6,000 pounds gross vehicle weight) are generally regulated as trucks and classified at truck SUVs for this report. In this report, vehicles are disaggregated into five vehicle types: sedan/wagon, car SUV, truck SUV, pickup truck, and minivan/van. All vehicle types are at record low CO 2 emissions however, market shifts away from cars and towards sport utility vehicles (SUVs) and pickups have offset some of the fleetwide benefits New vehicle estimated real-world CO 2 emissions are at a record low and fuel economy is at a record highĢ.
