Does Using Cruise Control Really Save Gas? A Research-Based Analysis

A Quick Overview

Key Points Information
Research Findings Multiple studies have shown that using cruise control can lead to fuel savings, especially on long highway drives with consistent speed.
Maintaining Speed Cruise control helps maintain a constant speed, reducing unnecessary acceleration and deceleration, which can improve fuel efficiency.
Smoother Driving The steady speed maintained by cruise control helps avoid sudden speed changes, leading to smoother driving and improved fuel economy.
Reduction in Variances By minimizing speed fluctuations, cruise control reduces the impact of external factors like wind resistance, resulting in fuel savings.
Efficiency vs. Terrain Cruise control is most effective on flat or gently rolling terrain, where maintaining a constant speed is easier. In hilly or mountainous regions, its impact on fuel savings may be less significant.
Driver Behavior Individual driving habits, such as rapid acceleration or heavy braking, can influence fuel consumption, even when using cruise control.
Overall Impact While cruise control can contribute to fuel savings, it is one factor among many. Other considerations like traffic conditions, vehicle maintenance, and driving style also play a role in fuel efficiency.

Cruise control is a feature found in many modern vehicles that allows drivers to set a desired speed for their vehicle, which the car then maintains automatically. One common claim about cruise control is that it can help save gas, leading to increased fuel efficiency and potential cost savings for drivers. In this blog post, we will explore whether using cruise control actually leads to fuel savings, based on research and scientific analysis.

The Mechanics of Cruise Control

Before delving into the fuel-saving aspect of cruise control, it’s important to understand how the system works. When activated, cruise control uses electronic sensors to monitor the vehicle’s speed and adjust the throttle accordingly to maintain the set speed. This eliminates the need for drivers to manually modulate the throttle pedal, resulting in a consistent speed and potentially reducing speed fluctuations that can impact fuel consumption.

Fuel Efficiency and Cruise Control

To determine whether cruise control can genuinely save gas, several studies have been conducted to evaluate its impact on fuel efficiency. Here are some key findings:

  1. Consistent Speed: Cruise control helps maintain a steady speed on highways or long stretches of road. This consistency can reduce the tendency for drivers to accelerate and decelerate frequently, which is a common behavior that negatively affects fuel efficiency.

  2. Optimized Acceleration: Cruise control typically provides a smoother and more controlled acceleration compared to manual driving. This can prevent unnecessary aggressive acceleration, which can consume more fuel.

  3. Reduction in Speed Variations: By minimizing speed fluctuations, cruise control helps eliminate the need for frequent adjustments to maintain a constant speed. This stability can positively impact fuel efficiency, as rapid acceleration and deceleration events tend to use more fuel.

  4. Ideal for Long, Flat Roads: Cruise control is particularly effective on long, flat stretches of road where the vehicle can maintain a constant speed for extended periods. In these situations, cruise control can contribute to fuel savings by ensuring a consistent and optimized throttle input.

Factors Influencing Fuel Efficiency

Although cruise control can positively impact fuel efficiency, it is important to note that other factors also play a role. Here are a few considerations to keep in mind:

  • Terrain: Hilly or mountainous terrains may limit the effectiveness of cruise control in terms of fuel efficiency. The system may struggle to maintain a constant speed in such conditions, potentially leading to increased fuel consumption.

  • Traffic Conditions: In heavy traffic situations, cruise control may not be practical due to the need for frequent acceleration and braking. Stop-and-go traffic can negate the fuel-saving benefits of cruise control.

  • Weather Conditions: Adverse weather conditions, such as rain, snow, or strong winds, may affect the performance of cruise control. In such cases, it is important for drivers to exercise caution and rely on manual control to ensure safety.


Based on research and scientific analysis, it can be concluded that using cruise control has the potential to save gas and improve fuel efficiency under ideal conditions. Consistent speed, optimized acceleration, and reduced speed fluctuations contribute to these fuel-saving benefits. However, it is essential to consider external factors such as terrain, traffic conditions, and weather, which can impact the effectiveness of cruise control.

While cruise control can be a useful tool for maximizing fuel efficiency, it is important for drivers to be aware of their surroundings and adapt their driving style accordingly. By combining the benefits of cruise control with situational awareness, drivers can make informed decisions and strive for optimal fuel economy while enjoying the convenience offered by this technology.

Does using cruise control really save gas?

Using cruise control can indeed save gas in certain situations. When engaged, cruise control helps maintain a consistent speed, preventing unnecessary acceleration and deceleration. This stability reduces fluctuations in fuel consumption, leading to potential fuel savings, especially during long highway drives where steady speed can be maintained. However, the extent of fuel savings may vary depending on factors such as terrain, traffic conditions, and individual driving habits.

Is using cruise control more fuel-efficient than manual speed control?

In general, using cruise control tends to be more fuel-efficient than manual speed control. Cruise control systems are designed to optimize fuel consumption by maintaining a steady speed, avoiding unnecessary acceleration, and minimizing speed variations. Compared to manual speed control, where drivers may unintentionally apply more throttle or vary their speed, cruise control can provide better fuel efficiency, especially on long, relatively flat stretches of road.

Are there any situations where using cruise control may not save gas?

While using cruise control can save gas in many scenarios, there are situations where its effectiveness may be limited. For example, in hilly or mountainous terrain, the cruise control system may continuously adjust the throttle to maintain the set speed, resulting in increased fuel consumption. Additionally, in heavy traffic or urban driving conditions with frequent stops and starts, the constant engagement and disengagement of cruise control may not yield significant fuel savings.

Does the type of vehicle impact the fuel savings achieved by using cruise control?

Yes, the type of vehicle can impact the fuel savings achieved through cruise control. Generally, vehicles with smaller engines or those optimized for fuel efficiency may experience more noticeable fuel savings when using cruise control. Larger, less aerodynamic vehicles or those with higher horsepower engines may have fewer fuel-saving benefits due to their inherent design and power requirements.

Are there any additional benefits to using cruise control besides fuel savings?

Yes, using cruise control offers additional benefits beyond potential fuel savings. It can help reduce driver fatigue during long trips by allowing the driver to maintain a constant speed without constantly pressing the accelerator pedal. Cruise control also promotes a smoother driving experience, which can enhance passenger comfort and reduce the likelihood of abrupt braking or acceleration.

Are there any downsides or considerations to using cruise control?

While cruise control can be beneficial, there are some downsides and considerations to keep in mind. It’s important to remain attentive and prepared to disengage the cruise control system if unexpected situations arise on the road. Additionally, using cruise control in certain weather conditions, such as heavy rain or icy surfaces, may not be recommended for safety reasons. It’s crucial to use cruise control responsibly and be aware of the potential limitations in specific driving scenarios.
