Model year rollovers between 2026 and 2028 will reveal how each carmaker balances hybrid volume against EV launches to thread the emissions and CAFE needles.
Supplier contracts for batteries and minerals will determine who can preserve 30D eligibility while keeping bill-of-materials costs in check.
