These Car Accessories Could Be Killing Your Gas Mileage

TL;DR

Experts warn that some common car accessories may be decreasing fuel efficiency. This report identifies which accessories are problematic and explains why drivers should reconsider their use.

Recent investigations suggest that certain car accessories may be responsible for reducing gas mileage. While these accessories are marketed for convenience or aesthetics, experts warn they could be negatively impacting fuel efficiency. This development matters because many drivers may be unknowingly spending more on fuel due to these add-ons.

Automotive experts have identified several common accessories—such as roof racks, heavy-duty floor mats, and aftermarket spoilers—that could be reducing fuel economy. According to a recent analysis by the National Institute for Automotive Efficiency, these accessories can increase air resistance or add weight, both factors that diminish a vehicle’s miles per gallon.

While some accessories like roof racks are designed for utility, their improper use or overloading can significantly impact fuel consumption. The study emphasizes that the effect varies depending on the accessory design, vehicle type, and driving conditions. Experts recommend drivers evaluate the necessity of such add-ons, especially if they are used frequently or improperly installed.

Officials from the Department of Energy suggest that removing unnecessary accessories can improve fuel efficiency by up to 10%, translating into substantial savings over time. However, it is still unclear how widespread the problem is across different vehicle models and usage patterns, as ongoing research continues to gather data.

Background on Vehicle Accessories and Fuel Efficiency

Over the past decade, the popularity of various car accessories has grown, with many marketed for aesthetic appeal or added functionality. However, automotive experts have long debated the impact of these accessories on vehicle performance. Previous studies have shown that roof racks, spoilers, and heavy floor mats can influence aerodynamics and weight, but comprehensive data on their cumulative effect is limited. Recent investigations aim to clarify these impacts, especially as fuel economy standards tighten globally.

“Many aftermarket accessories are designed without considering their aerodynamic or weight impacts, which can significantly reduce fuel efficiency over time.”
