Active Eco is a feature found in Hyundai Sonata vehicles designed to enhance fuel efficiency by modifying how the engine and transmission operate. This system is particularly beneficial for drivers looking to reduce fuel consumption without making significant changes to their driving habits.

What is Active Eco?

Active Eco mode optimizes the vehicle's performance for better fuel economy. When activated, it alters the shifting patterns of the transmission and adjusts throttle response, which leads to more gradual acceleration. This means that the car will shift to higher gears sooner and will not downshift as quickly when you need extra power, such as during highway merges or passing slower vehicles.

How Does Active Eco Work?

The Active Eco system operates automatically once engaged. Here’s how it functions:

  • Throttle Response: The system dulls throttle response, requiring more pressure on the accelerator for the same level of power.

  • Transmission Shifting: It modifies shifting patterns, encouraging early shifts to higher gears, which helps maintain lower engine RPMs and reduces fuel consumption.

  • Fuel Management: During deceleration, the system cuts off fuel supply, further enhancing efficiency.

Engaging Active Eco can lead to an improvement in fuel economy of up to 7%, depending on driving conditions and habits. However, drivers may notice a decrease in acceleration responsiveness, especially in situations requiring quick speed adjustments.

When Should You Use Active Eco?

Active Eco mode is best used in situations where fuel efficiency is a priority:

  • City Driving: Ideal for stop-and-go traffic where smooth acceleration can save fuel.

  • Constant Speed Driving: Effective on highways where maintaining a steady speed is possible.

However, it may be less suitable for:

  • Merging or Overtaking: In scenarios that require rapid acceleration, such as merging onto highways or passing other vehicles, it may be beneficial to turn off Active Eco for better performance.

How to Activate and Deactivate Active Eco

To use Active Eco in your Hyundai Sonata, locate the Eco button, typically found near the driver's left knee. Pressing this button will activate the feature, indicated by an illuminated LED light on the dashboard. To deactivate it, simply press the button again.

Conclusion

Active Eco is a valuable feature for Hyundai Sonata owners looking to maximize fuel efficiency. By adjusting engine performance and transmission behavior, it helps drivers save on fuel costs while maintaining a comfortable driving experience. While it may reduce responsiveness during acceleration, its benefits in terms of fuel savings make it a useful tool for everyday driving.
