Accessorize Wisely: How Common Car Add-Ons Can Devastate Fuel Economy

The auto industry has witnessed a significant shift in recent years, with car enthusiasts and owners alike opting for custom modifications and accessories to personalize their vehicles. However, while these add-ons may enhance the appearance and functionality of a car, they can have a detrimental impact on fuel economy. According to a recent report, U.S. consumers spent over $52 billion dollars accessorizing and modifying their vehicles in 2024, a trend that is expected to continue, with the Car Modification Market forecast to grow to over $80 billion dollars by 2034.

Background & Context

For many car enthusiasts, accessorizing is an essential aspect of customizing their vehicles. Whether it's to enhance performance, increase driving pleasure, or simply to express personal style, car owners are constantly seeking new ways to personalize their vehicles. However, while these add-ons may seem harmless, they can have a significant impact on fuel economy. In this article, we will explore the effects of common car accessories on fuel economy and what car owners can do to minimize their impact.

Manufacturers design and build cars to achieve maximum fuel economy, taking into account various factors such as aerodynamics, weight, and rolling resistance. However, when car owners add accessories such as roof racks, mud flaps, and towing packages, they can compromise the vehicle's aerodynamics, causing it to work harder to maintain speed, which can lead to reduced fuel economy.

Key Details

According to experts, adding accessories can have a significant impact on fuel economy. "Body kits and rear wings that claim to improve aerodynamics and increase fuel efficiency actually do the opposite," said Chris Pyle, an auto expert. "They create more drag, forcing the engine to work harder to maintain speed, which can lead to reduced fuel economy." Even small items such as window deflectors and light bars can affect fuel economy, with Eliot Vancil of Fuel Logic LLC stating that while the effect of most add-ons is usually small, adding multiple accessories can quickly lower fuel economy.

The impact of roof racks is particularly significant, with Vancil stating that even when not carrying cargo, car roof racks can cause aerodynamic drag and reduce fuel economy. "Roof racks can reduce fuel economy up to five MPG," he added, suggesting that removing the crossbars when not in use can help minimize the impact.

What Experts Say

Experts emphasize that the effects of accessories on fuel economy can be significant, and that car owners should be aware of the potential consequences. "Car owners should consider the impact of accessories on fuel economy before making a purchase," said Pyle. "It's not just about aesthetics; it's about the practical implications of these add-ons on fuel efficiency." Vancil added that car owners should also consider the weight and rolling resistance of accessories, as these can also have a significant impact on fuel economy.

Key Takeaways

• Common car accessories such as roof racks, mud flaps, and towing packages can compromise a vehicle's aerodynamics, causing it to work harder to maintain speed and reducing fuel economy.
• Adding multiple accessories can quickly lower fuel economy, with the impact being more significant than the individual effects of each add-on.
• Even small items such as window deflectors and light bars can affect fuel economy, and car owners should be aware of the potential consequences.
• Car owners should consider the weight and rolling resistance of accessories, as these can also have a significant impact on fuel economy.

What This Means For You

As a car owner, it's essential to be aware of the potential impact of accessories on fuel economy. While add-ons may seem harmless, they can have a significant impact on your vehicle's performance and fuel efficiency. Consider the following tips when accessorizing your vehicle:

* Research the impact of accessories on fuel economy before making a purchase.* * Consider the weight and rolling resistance of accessories, as these can also have a significant impact on fuel economy.* * Remove crossbars from roof racks when not in use to minimize the impact on fuel economy.* * Be aware of the individual effects of each add-on, as these can add up to significant reductions in fuel economy.

By being aware of the potential impact of accessories on fuel economy, car owners can make informed decisions about their vehicle's performance and fuel efficiency. Whether it's to enhance performance, increase driving pleasure, or simply to express personal style, car owners can accessorize wisely and minimize the impact on fuel economy.
