The Trump administration has announced plans to reevaluate the automatic engine start-stop feature in vehicles, a system that shuts off the engine when a car is stationary to conserve fuel. EPA Administrator Lee Zeldin stated that the agency would begin examining modifications to this technology, which has been widely criticized by drivers.
Zeldin highlighted the inconvenience caused by the start-stop system, referring to it as a feature that makes cars “die at every red light.” He emphasized the need to address public dissatisfaction with the technology.
Initially introduced by European manufacturers in hybrid vehicles, the start-stop system has become common in various car models, including SUVs and pickup trucks. While it offers a 3% to 10% improvement in fuel economy, many drivers find the feature disruptive. Although some automakers, such as Buick, Ford, GM, Volvo, and Lincoln, have provided options to disable the system temporarily, a permanent off switch is typically unavailable.
The EPA’s current fuel economy testing protocols consider the start-stop feature’s impact, averaging results from tests with the system both activated and deactivated. This approach affects the fuel economy ratings displayed on vehicle window stickers.
The administration’s initiative to reassess the start-stop system aligns with broader efforts to reduce regulatory burdens and enhance consumer choice in automotive features.
