EPA to End Credits for Annoying Stop-Start Systems?

The EPA, under the Trump administration, is reportedly questioning the value of stop-start systems in vehicles, suggesting they might disappear from future models.

Are Stop-Start Systems on Their Way Out?

For years, stop-start systems have been touted as a fuel-saving technology. The premise was simple: reduce fuel consumption by automatically turning off the engine when a vehicle is idle, like at traffic lights. The EPA now suggests these systems may not be worth the hassle.

The Promise vs. Reality

The idea gained traction in the early 2000s, with claims that idling cars wasted significant fuel. Proponents suggested stop-start could save 4% to 10% of fuel in urban settings. Today, these systems are in a majority of US cars, and over 90% in Europe and Japan. Manufacturers received fuel economy credits for including the technology, but it appears those credits might be coming to an end.

EPA Puts the Brakes on Stop-Start

EPA administrator Lee Zeldin argues that the emissions reduction from stop-start systems is minimal, while causing premature wear on starter motors. The annoyance factor for drivers is significant, and the estimated fuel savings hover around 4% to 5%.

The Annoyance Factor

While stop-start systems were intended to be most effective in stop-and-go city driving, many drivers find them irritating and disable them. Early versions were clunky, and while improvements have been made, the negative perception persists.

The Future: End of the Road for Stop-Start?

If the EPA removes the credits incentivizing their use, automakers may abandon stop-start systems, especially as the industry shifts toward electric vehicles.

A Failed Experiment?

Stop-start systems represented an early attempt to reduce emissions, but with the rise of electric and hydrogen vehicles, their usefulness is waning. Consumer Reports has noted the inconsistent performance and annoyance associated with the technology.

The potential removal of stop-start systems raises questions about whether they will be missed or celebrated. What do you think of the stop-start system? Do you find it annoying?
