This Forgotten Feature in the 2015 Hyundai Elantra Could Save You Hundreds on Gas Forever If you’re a fan of properly forgotten car features, the 2015 Hyundai Elantra might just be your new best friend. While the Elantra is widely praised for its affordability and style, one rarely discussed but powerful fuel-saving trick could help you slash your gas expenses by hundreds—without dropping a penny on maintenance or replacing batteries. ### What Is This Overlooked Fuel-Saving Feature? Okay, not exactly a “feature” in the traditional sense, but a largely forgotten built-in driving mode and efficiency behavior engineered specifically for the 2015 Hyundai Elantra. Known as the Eco Mode or more informally called the “Efficient Driving Mode,” this system subtly adjusts how the car manages acceleration, powertrain response, and cruise control to maximize fuel economy—especially on city roads and stop-and-go traffic.
