TL;DR
Some common car accessories can decrease fuel efficiency, according to recent reports. Drivers should be aware of which additions might be harming their gas mileage to save money and reduce emissions.
Several popular car accessories may be unintentionally reducing fuel efficiency, according to recent analyses. Experts warn that items such as roof racks, bike carriers, and certain aftermarket modifications could be increasing aerodynamic drag or adding weight, leading to higher fuel consumption. This development matters because many drivers may be unaware that these accessories are costing them money at the pump.
According to reports from Family Handyman, accessories like roof racks, bike carriers, and certain aftermarket add-ons can negatively impact gas mileage. These items often increase the vehicle’s aerodynamic drag or weight, which forces the engine to work harder and consume more fuel. While these accessories are popular for their convenience and utility, their effect on fuel efficiency is often overlooked.
Experts emphasize that the extent of the impact varies depending on the accessory’s design, size, and how often the vehicle is used with these additions. For example, roof-mounted carriers can increase aerodynamic drag significantly, especially at highway speeds, leading to measurable decreases in fuel economy. Some studies suggest that fuel efficiency could drop by 10% or more when such accessories are used regularly.
Automakers and industry analysts recommend that drivers consider removing or minimizing the use of these accessories when not needed, especially for long highway trips. They also advise checking for accessories that are poorly installed or designed without aerodynamic considerations, as these can exacerbate fuel consumption issues.
Implications of Accessories on Fuel Costs and Emissions
This information is significant because it highlights an often-overlooked factor affecting fuel expenses and vehicle emissions. Drivers who are unaware of the impact of accessories may be spending more on fuel and contributing to higher emissions without realizing it. Reducing unnecessary accessories can lead to cost savings and environmental benefits, making this a relevant concern for everyday drivers and policymakers alike.

Prevalence of Car Accessories and Fuel Efficiency Concerns
Many vehicle owners add accessories such as roof racks, bike carriers, spoilers, and custom modifications to enhance utility or aesthetics. However, these additions are not always optimized for fuel efficiency. Past studies and industry observations have shown that aerodynamic drag and weight are key factors influencing gas mileage, especially at highway speeds. The recent warnings from Family Handyman align with ongoing advice from automotive experts to minimize non-essential accessories for better fuel economy.

Key Questions
Which car accessories most significantly affect gas mileage?
Roof racks, bike carriers, and poorly designed spoilers are among the accessories most likely to reduce fuel efficiency due to increased aerodynamic drag and weight.
Can removing accessories improve my fuel economy?
Yes, removing or minimizing accessories like roof racks and bike carriers, especially during highway driving, can lead to measurable improvements in gas mileage.
Are all aftermarket accessories harmful to fuel efficiency?
No, the impact depends on the accessory’s design, size, and how often it is used. Well-designed, aerodynamic accessories may have minimal effect.
Should I replace my current accessories to save fuel?
If fuel economy is a priority, consider removing or replacing accessories that increase drag or weight, particularly for long-distance driving.
Will future vehicle designs reduce the impact of accessories on fuel economy?
It’s possible that automakers will develop more aerodynamic accessories or design standards to mitigate these effects, but current consumer choices remain relevant.
