Which is better cruise control or adaptive cruise control?

Cruise control and adaptive cruise control are two distinct technologies that offer different driving experiences. While both systems help maintain a consistent speed, adaptive cruise control provides additional features that can make driving safer and more convenient. In this article, we'll explore the key differences between these two systems and help you determine which one is better suited for your needs.


Cruise Control: The Basics


Cruise control is a feature that allows drivers to maintain a constant speed without continuously pressing the accelerator pedal. Once activated, the system will automatically maintain the set speed, adjusting the throttle as needed to maintain the desired velocity. This can be particularly useful on long highway drives, helping to reduce driver fatigue and improve fuel efficiency. Cruise control is a relatively simple and straightforward system that has been around for decades.


Adaptive Cruise Control: The Next Generation


Adaptive cruise control (ACC) is a more advanced version of traditional cruise control. In addition to maintaining a set speed, ACC also uses sensors to detect the distance and speed of the vehicle in front of you. Adaptive cruise control will automatically adjust your speed to maintain a safe following distance, slowing down or speeding up as needed to match the pace of the vehicle ahead. This can help prevent rear-end collisions and make driving in heavy traffic or on the highway much more relaxed and comfortable.


Key Differences



  • Speed Adjustment: Cruise control maintains a constant speed, while adaptive cruise control adjusts the speed to maintain a safe following distance.

  • Safety Features: Adaptive cruise control offers additional safety features, such as automatic braking and collision avoidance, that can help prevent accidents.

  • Convenience: Adaptive cruise control can make driving in stop-and-go traffic or on the highway much more convenient, as the system handles the speed adjustments for you.

  • Cost: Adaptive cruise control is generally more expensive than traditional cruise control, as it requires additional sensors and more advanced technology.


In summary, while both cruise control and adaptive cruise control can help make driving more comfortable and efficient, adaptive cruise control offers a more advanced and safer driving experience. The added features of adaptive cruise control, such as automatic speed adjustments and collision avoidance, can make it the better choice for many drivers, especially those who frequently drive on the highway or in heavy traffic.

Is cruise control better or worse for gas mileage?


Generally speaking, yes. Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.



Can I trust adaptive cruise control?


“If [buyers] end up getting adaptive cruise control, 90 percent of the people report they are using it and they report high satisfaction,” she says.



Is adaptive cruise control better than cruise control?


Conventional Cruise Control can maintain a steady speed that you set. Adaptive cruise control (ACC) is an enhancement of conventional cruise control. ACC automatically adjusts the speed of your car to match the speed of the car in front of you. If the car ahead slows down, ACC can automatically match it.



What are the disadvantages of adaptive cruise control?


Cons of adaptive cruise control include: There may be potential delayed braking time when the system is in use. Drivers may set higher speeds, which could cause aggressive braking as their vehicle rapidly approaches vehicles.



Does adaptive cruise control use more gas?


This consistent speed reduces the engine workload and leads to more efficient fuel usage. Moreover, modern adaptive cruise control systems further enhance efficiency by adjusting speed smoothly in response to traffic conditions, avoiding abrupt speed changes that can consume extra fuel.



When should you not use adaptive cruise control?


Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control.



Can cruise control be upgraded to adaptive cruise control?


Can I Add Adaptive Cruise Control to My Car? Yes, you will find aftermarket adaptive cruise control kits available. Depending on the features, they range in cost from $250 to nearly $4,000.



How much extra is adaptive cruise control?


How Much Does an Adaptive Cruise Control System Cost? According to ExtremeTech, The cost of an adaptive cruise control system will vary depending on how many features you want. If you're going to have an ACC with all available features, you should be willing to pay anywhere between $2000 and $2500.



Is adaptive cruise control worth having?


Interestingly, your insurance premiums might be slightly lower if your car has adaptive cruise control fitted, as the camera equipment it comes with is considered to be a safety-improving tech. Maintaining a steady speed could also be good for your pocket, as this will increase your fuel economy.



What is the best SUV with adaptive cruise control?


The best hybrid SUV with adaptive cruise control is the Toyota Highlander Hybrid (9.2 / 10 iSeeCars score), with the Tesla Model X being the best electric SUV with adaptive cruise control (8.4 / 10 iSeeCars score). The practicality of SUVs has made them the most popular vehicle type among today's consumers.
