What dealers should know as demand peaks before the Sept. 30 credit deadline!

Momentum Shift in August

EV Sales Growth Update. Shoppers pulled EV demand forward ahead of the federal tax credit sunset, pushing U.S. new EV sales to ~146,000 units in August—an all-time monthly record—at ~9.9% market share. The spike sets up a hot September and a potentially choppy Q4 as policy support fades and price/inventory strategy takes center stage. 

New EV Sales (August)

• ≈146,000 units sold; ~9.9% share of new vehicles.
• Tesla ≈sold approximately 55,500 units in the U.S., setting a 2025 monthly record for the brand. GM also flagged its best EV month ever. (Brand mix shifted, with more competition in volume segments.)
  

Used EV Sales (August)

• Public, nationally consolidated used-EV unit counts for August (with MoM/YoY splits by brand) haven’t been released by the usual trackers yet. Quarterly sources continue to indicate a tightening of days’ supply and resilient pricing into Q3. I’ll plug in the exact August used-EV units once Cox/Recurrent or similar publishes them.
  

Inventory & Days’ Supply

• New vehicles (all powertrains): U.S. inventory opened August at 2.68M units; 73 days’ supply. As of Sept. 1, inventory stood at 2.76M; 77 days’ supply—still below last year. Translation: August sales ran hot and pulled stock down vs. July, then model-year changeover helped refill some lots heading into September. 
• Used market (all powertrains): August ended at ~42 days’ supply, down from 46 in July. (EV-specific used days’ supply for August isn’t published yet.) 

Prices & Incentives

• New EV ATP: $57,245 in August, +3.1% MoM vs. July’s revised $55,562; roughly flat YoY.
• Industry incentives (all powertrains): 7.2% of ATP in August, slightly softer vs. July (7.3%). Expect OEMs to lean tactically on incentives through Sept. while demand remains credit-driven. 
• Used EV pricing: August-specific national averages aren’t out yet from the main trackers; Q3 reads show firm demand, stabilizing prices, and faster turns for rebate-eligible units. 

What Dealers Should Do Next

• Front-load September: With the tax credit ending Sept. 30, expect another elevated month—then a potential air pocket. Price to clear aged EV stock and lock in trade-ins now. 
• Watch mix and competition: Tesla volume rose, but share slipped; GM, Hyundai, and others are pressing advantages in fresh nameplates and pricing. Flex your model-mix advertising to where shoppers are moving. 
• Prepare for post-credit volatility: If incentives normalize and credit tightens, ATP sensitivity rises. Keep appraisal spreads tight and refresh payment-based offers quickly as lender programs shift.
