Market Outlook
With federal EV tax credits now expired, the market is entering a new phase driven by fundamentals rather than incentives. Continued adoption will depend on affordability, charging accessibility, and consumer confidence in battery life.
As used EV prices near parity with gasoline models, the long-term growth of the segment will rely on cost management, infrastructure expansion, and consistent vehicle availability.
The 2026 Conference of Automotive Remarketing convened with a mandate to involve a new constituency — fleet managers — and an updated mission to demonstrate unrealized value in de-fleeted vehicles.
The Association, dedicated to advancing the remarketing phase of the vehicle lifecycle, held its kick-off meeting on April 16 at the 2026 Conference of Automotive Remarketing (CAR) in Cleveland.
From a Wall Street analyst's take on remarketing's key players to whether fleets need their own version of Carfax, CAR 2026's afternoon roundtables will answer key operational and industry questions.
The company has processed more than 10 million pounds of EV battery black mass, highlighting growing demand for recycling and lifecycle management as more electric vehicles enter the used market.
A panel at the 2026 Conference of Automotive Remarketing will examine how resale value is created across the vehicle lifecycle and which traditional remarketing practices still deliver ROI.
