Q3 2025 Auto Market: Strong Q3, Cautious Q4—What It Means for Vehicle Logistics

The U.S. auto industry is navigating one of its most complex landscapes in years, part multi-level chess game, part balancing act between supply, policy, and affordability.

Key signals and the auto industry’s current vibe

From Cox Automotive’s Q3 2025 Industry Insights & Sales Forecast Call (held Sept 25):

  • Q3 brought resilient demand and record EV sales ahead of incentive expirations.
  • Q4 looks softer as tariffs and tighter supply push prices higher.
  • 2026 should be modestly stronger—if the labor market holds.

The macro dashboard: mostly yellow, not red

  • Growth: Cox expects ~2% GDP for Q3; Q4 weaker, but “no more negative quarters.”
  • Jobs: Unemployment at 4.3% and expected to drift only slightly higher. The watch-item is slower hiring amid AI productivity gains and lower immigration.
  • Rates & credit: Fed cuts haven’t yet lowered auto APRs; incentives on new loans tightened in September. Credit is flowing—better for high-score buyers—but trending tighter. Both gauges sit at yellow with potential to improve by spring.
  • Consumer: Real incomes are still growing; demand durability depends on job stability.

Tariffs & pricing: no free lunch

New trade frameworks add cost throughout the supply chain:

  • Imported vehicles: ~$5,500 higher average cost.
  • US-assembled: +~$1,000 (parts, initially) + ~$800 (steel & aluminum).
  • MSRP outlook: Cox sees +4–6% (possibly 8%) average inflation by this time next year—on top of a pre-COVID trend that was already ~3%/yr.

Expect more “shrinkflation” (feature deletions, trim reshuffles) and selective MSRP increases as OEMs defend margins. Affordability pressure migrates downstream—to dealers, suppliers, and ultimately consumers.

New-vehicle sales: big players get bigger

  • 2025 forecast raised to 16.1M (from 15.7M), with Q4 deceleration as tariff costs show up and EV demand cools post-credits.
  • Q3 leaders:
    • GM: >700k units, +7% YoY; YTD +10% led by Equinox & Traverse.
    • Toyota: +17% YoY in Q3; YTD +8%+ on Tacoma & Sienna strength.
    • Stellantis: –0.6% YoY in Q3; YTD –8%, share down ~1 pt; Jeep Cherokee refresh helps late Q4/2026.
    • Tesla: –6% YoY in Q3 but +9% QoQ; share –0.5 pt YTD; likely softer Q4 after the EV rush.
  • Concentration trend: GM, Toyota, Ford, Hyundai—top four up 9% YTD while the rest are down 2%. Broad portfolios are winning.

Supply, incentives, and price: upward pressure returns

  • Supply: ~2.8M units in stock/in-transit (–4% YoY), 76 days of supply (–11% YoY). Tighter inventories reduce deal pressure.
  • Incentives: Averaged 7.2% of ATP in August. Post-tariff pullback hasn’t materialized—yet.
  • Prices: $49,077 ATP in August (near long-term high). Up 0.6% YoY—highest pace in ~2.5 years—and likely to rise faster as 2026 models (built post-tariff) hit lots.

EVs: a record quarter, then a hangover

  • Q3 milestone: ~410k EVs and ~10% share—a record—powered by pre-expiration incentive buying.
  • Leasing = the EV unlock: EV lease penetration surged (industry example rates >50% recently), tripling the broader industry average and bridging affordability. Without federal support, lease penetration should ease.
  • Inventory: EV day-supply fell to ~62 days in August—below ICE (~78 days)—tightening fastest among major segments.
  • Near-term: Expect Q4 EV cooldown as incentives lapse, with hybrids and PHEVs absorbing demand.

Hybrids

Hybrids and plug-in hybrids are quietly reshaping the mix. One in four vehicles sold now has an alternative powertrain. Toyota leads in hybrids with 49% share; Jeep leads plug-ins at 25%. These technologies are acting as bridges for consumers not ready to go full EV.

Used market: fundamentals remain solid

  • Mannheim wholesale values ran above 2024 and long-term norms after a spring spike; seasonal slippage is milder than usual.
  • Lease-return mix flips ahead: by 2027, lease returns shift to ~16% EV / 5% PHEV / 6% HEV / ~72% ICE (vs. historically ~95% ICE). As positive equity evaporates and turns negative, returns rise, auction volumes increase, and pressure builds on wholesale values in returning segments.
  • Net-net: Used stays stable near current index levels; affordability keeps pushing buyers down-market.

Cox Automotive’s retail outlook line (next 12 months)

  • New sales: +1.5%
  • Retail new: +1.0%
  • Used: +2.3%
  • Retail used: +2.0%
  • Total retail: +1.5%

Q4 sets the tempo for 2026, with modest upside—but only if OEMs don’t overbuild and trigger heavier incentives.

Finished Vehicle Logistics Implications (AG view):

  • Flex capacity down in Q4, be ready to pivot up by spring.
  • Win on on-time, claim-free delivery—not rate cuts.
  • Treat EV handling (securement, dwell checks, winter routing) as a core competency.
  • Stand up fast-cycle lanes for growing auction/recon flows.
