Total new vehicle sales are projected to reach 4,080,755 units for the third quarter of 2026. This forecast represents a 0.7% decrease compared to the third quarter of 2025 and a 3.6% drop from the second quarter of 2026.
Why it matters
Economic headwinds, including sustained high interest rates and gas prices, are driving consumer hesitation across the national market. Despite this slowdown, replacement demand continues to provide a floor for sales volume.
New vehicle sales are forecast to hit 4,080,755 units this quarter, while vehicles currently take an average of 58 days to turn over in inventory. Notably, 2026 model-year vehicles captured 86% of all new-vehicle sales in September 2026.
The players
Edmunds

The details
Market volume is currently sustained primarily by higher-income households. Automakers have maintained a higher proportion of current-model-year inventory than seen in previous years, which contributes to the current sales velocity. Vehicles remain on dealer lots for an average of 58 days before finding a buyer, reflecting the cooling demand among broader consumer segments.
Timeline
2005 marked the beginning of historical data tracking for current-model-year vehicle sales.
Q3 2025 served as the year-over-year comparison period for sales volume statistics.
Q2 2026 provided the quarterly comparison period for sales volume statistics.
September 2026 saw current-model-year vehicles reach 86% of total sales.
Q3 2026 is the period covered by the 4,080,755 vehicle sales forecast.
The Home Front
This sales shift tracks against the historical record of current-model-year vehicle inventory monitoring established in 2005. The current concentration of new-model inventory marks a departure from historical norms as manufacturers balance supply against softening buyer demand.
If you are considering a vehicle purchase, keep in mind that the current 58-day average inventory turnover suggests that inventory levels remain relatively stable. Monitor your local interest rate environment, as economic factors continue to influence purchasing power for households.
The takeaway
New vehicle demand is cooling due to broader economic pressures, though high-income buyers are keeping the market active. Prospective buyers should track inventory turnaround times in their area to determine if local supply levels are providing increased leverage for negotiations.
