Vehicle Energy Performance Act of 2025
Summary
What This Bill Does
The Vehicle Energy Performance Act of 2025 replaces a technology-specific vehicle incentive with a relative energy-performance system. New qualified high energy performance passenger automobiles and light trucks can receive a tax credit up to $5,000 based on how far the vehicle's energy performance exceeds the prior model year's median relative to the best prior-year vehicle. Beginning with model year 2029, manufacturers owe a low vehicle energy performance fee up to $5,000 when a passenger automobile or light truck falls below the prior model year's median energy performance, using a similar formula. The bill also updates dual-fueled automobile fuel-economy treatment by requiring the Administrator to apply the formula beginning with model year 2026 and review it every three years using real-world data if possible, and it expands labels to show alternative-fuel and multi-day average fuel economy.
Who Benefits and How
Consumers buying high energy performance vehicles benefit from a tax credit that can reach $5,000. Automakers producing above-median efficiency vehicles benefit from a market incentive tied to relative performance rather than one technology. Alternative-fuel vehicle buyers benefit from labels showing fuel economy on alternative fuel and mixed fuel use. Energy-efficiency advocates benefit from both incentives for high performers and fees on low performers.
Who Bears the Burden and How
Manufacturers of low energy performance vehicles face a fee of up to $5,000 per covered vehicle beginning with model year 2029. The Treasury Department and IRS must administer the credit and low-performance fee formulas. Vehicle manufacturers must track energy performance relative to median and best prior-year models. EPA or fuel-economy administrators must review dual-fuel formulas every three years and update labeling data.
Key Provisions
- Creates a tax credit up to $5,000 for new high energy performance motor vehicles.
- Imposes a low vehicle energy performance fee up to $5,000 beginning with model year 2029.
- Uses prior model-year median and best performance values to calculate credits and fees.
- Requires dual-fuel formula review every three years and expanded fuel-economy label information.
