Overview: A Policy Shock to the EV Revolution

The Big Beautiful Bill (BBB) is a piece of legislation that aims to reallocate federal energy and transportation funds, significantly rolling back subsidies and incentives for clean energy technologies. Passed by the U.S. House of Representatives in March 2025, the bill is expected to be taken up by the Senate by mid-July, where it faces a tight vote amid procedural negotiations.

The electric vehicle (EV) sector has been one of the most dynamic growth areas in the global shift toward decarbonization. In the U.S., that momentum has largely been fueled by tax credits, domestic battery investments, and public charging infrastructure programs. But with the introduction of the BBB, the tide is turning. While pitched as a “rationalization” of federal energy spending, the bill delivers a sharp blow to EV economics and signals a broad political pivot away from transportation electrification.

In this article, we examine the BBB’s major provisions that affect the EV sector, analyze likely outcomes for automakers and consumers, and assess broader implications for U.S. decarbonization and global competitiveness.

Key Provisions Targeting EVs

Unlike past legislation that supported EV adoption, the BBB introduces several measures that either directly penalize EV users or eliminate long-standing support mechanisms:

• Annual $250 Federal EV Registration Fee: Introduced to offset declining gasoline tax revenue, this new fee adds recurring cost to EV ownership, disproportionately impacting budget-conscious consumers.
• Elimination of the Federal EV Tax Credit: The $7,500 incentive for new EV purchases is phased out immediately, undercutting demand and removing a major selling point in dealer showrooms.
• New Car Loan Interest Deduction (Excludes EVs): A new provision allows consumers to deduct interest on car loans, but only for gasoline-powered vehicles. This introduces a perverse incentive structure that favors higher-emission vehicles.
• Repeal of the 45X Advanced Manufacturing Credit: The elimination of this credit undercuts domestic battery manufacturing and supply chain development, key to cost reduction and national security.

Impacts on Automakers and Battery Supply Chains

The ripple effects of the BBB are already reverberating throughout the automotive and battery manufacturing sectors. For automakers, the abrupt policy shift has upended strategic plans built around federal incentives and projected EV demand growth.

Major automakers are reassessing their production timelines and investment priorities. Ford has paused development of its next-generation electric pickup, while Stellantis is reconsidering a previously announced EV assembly plant in the Midwest. Even Tesla, which has typically relied less on subsidies, has acknowledged delays in expanding its energy storage product lines.

Battery manufacturing, essential to the future of EV affordability and availability, has been hit particularly hard. The repeal of the 45X tax credit removes a key economic pillar supporting domestic cell and module production. Projects involving major players such as LG Energy Solution, SK On, and Panasonic are being slowed or shelved. Industry insiders warn this could cede further ground to Chinese and Korean battery firms, who now face less incentive to establish or expand U.S.-based operations.

The uncertainty introduced by the BBB is also discouraging long-term R&D efforts in battery chemistry, recycling, and grid integration, areas where the U.S. had been catching up to global leaders. Companies that had committed to U.S.-based supply chains are now reevaluating the feasibility of those plans and looking abroad for more predictable policy environments.

Taken together, these developments suggest a looming contraction in U.S.-based EV manufacturing capacity and innovation, raising questions about future job creation, trade competitiveness, and climate resilience.

Consumer Affordability and Market Distortion

The EV sector has made notable progress in bringing down prices, but the removal of tax credits and the introduction of fees create new affordability hurdles. According to Kelley Blue Book data, the average EV price in Q1 2025 was $53,000: still significantly above comparable gasoline-powered vehicles.

Without the $7,500 credit, the total cost of ownership rises sharply, especially when factoring in the new annual $250 fee. Meanwhile, buyers of gasoline-powered vehicles benefit from a new car loan interest deduction; a benefit that, paradoxically, grows with higher loan amounts and longer repayment terms.

Cost Element	EV Buyer (Post-BBB)	Gasoline Vehicle Buyer (Post-BBB)
Federal Tax Credit	$0	N/A
Registration Fee (Annual)	+$250	$0
Loan Interest Deduction	Not eligible	Eligible
Battery/Parts Local Sourcing	Unsubsidized	Not relevant

Broader Clean Energy and Climate Implications

While the BBB is not exclusively anti-EV, its net impact clearly disadvantages the sector. It weakens the transportation sector’s ability to reduce emissions which is critical since this sector accounts for ~29% of total U.S. greenhouse gas emissions. It signals a broader retreat from federal clean energy leadership.

One of the most consequential aspects of the bill is the chilling effect it has on long-term decarbonization strategies. With key provisions like the 45X Advanced Manufacturing Credit repealed, the clean energy manufacturing base (beyond just EVs) faces increased cost pressure and competitive disadvantage globally. Solar, wind, and energy storage developers will likely experience similar setbacks due to shared supply chain dependencies and weakened investor confidence.

Private capital, which had surged into climate tech following the Inflation Reduction Act (IRA), is now entering a holding pattern. Venture and growth investors are signaling caution, pausing funding rounds and seeking safer regulatory environments in Europe and parts of Asia.

Moreover, the rollback undermines U.S. credibility in international climate diplomacy. The reversal comes at a time when the EU, China, and India are increasing their clean energy investments, raising concerns about America’s ability to meet its Paris Agreement targets and its competitiveness in the emerging green industrial economy.

For cities and states with ambitious clean transport and climate goals, the withdrawal of federal support places increased pressure on local resources and public-private partnerships. Without alignment between federal and subnational policies, the risk of regulatory fragmentation and stalled progress grows significantly.

Conclusion: A Roadblock to Electrification

The BBB represents a dramatic reversal in U.S. EV policy at a time when international peers are accelerating their own transitions. By disincentivizing consumer adoption, undermining domestic manufacturing, and distorting the vehicle market in favor of fossil fuels, the legislation adds uncertainty and headwinds to the road ahead.

In the absence of federal alignment, states, cities, and the private sector will need to innovate to keep the EV transition alive. But the BBB signals that the federal government’s foot is off the accelerator—and possibly back on the brake.
