Automakers Push to Replace Federal Gas Tax With Vehicle Weight Fees

A prominent automotive trade group is calling on the federal government to eliminate the traditional gas tax in favor of a new fee based on vehicle weight. This proposal aims to address the looming insolvency of the Highway Trust Fund, which is currently projected to run out of money by 2028.

The Alliance for Automotive Innovation argues that the rapid rise of electric vehicles has made the current per-gallon taxation model fundamentally obsolete. CEO John Bozzella stated that the existing system unfairly burdens drivers of older, less fuel-efficient vehicles while allowing others to bypass maintenance costs.

Under the proposed system, the tax burden would shift significantly toward heavier vehicles, including many modern SUVs and battery-electric models. These larger vehicles often cause more wear and tear on public roads, yet they currently pay less into the system than older, less efficient cars.

Industry leaders believe that a weight-based registration fee would provide a more stable and equitable source of revenue for long-term highway projects. This model would function similarly to a registration fee, ensuring that every vehicle on the road contributes to the maintenance of the national transportation network.

However, critics warn that the transition could lead to substantially higher annual costs for average motorists and small business owners. Logistics companies are particularly concerned that increased fees on heavy freight trucks will eventually result in higher prices for consumer goods across the country.

Environmental advocates have also voiced concerns that taxing vehicles based on their mass might inadvertently penalize consumers who choose long-range electric vehicles. Since large batteries add significant weight to a car, new buyers could face a financial disincentive when trying to switch to cleaner transportation options.

Legislative experts note that implementing such a massive overhaul of the federal tax code would require extensive bipartisan cooperation and years of planning. While the 2028 deadline for the Highway Trust Fund is approaching quickly, lawmakers remain deeply divided on the best path forward for funding.

Despite these challenges, the automotive group maintains that the current trajectory of the gas tax is mathematically impossible to sustain in a decarbonizing economy. They are urging Congress to begin pilot programs immediately to test the feasibility of weight-based tracking and billing systems on a national scale.
