A new electronic dashboard device has been developed to help drivers improve fuel efficiency while driving. The device shows drivers how to adjust their driving behavior to reduce fuel consumption by changing gear ratios, speed, and acceleration. By displaying information on engine power and speed, the device guides drivers to achieve a balance between engine efficiency and fuel consumption. The device uses color-coded fields to indicate different levels of economy, with the best driving behavior involving high accelerations at low engine speeds and high gear ratios. Road tests have confirmed that this approach leads to lower fuel consumption without compromising performance. Additional information on car speed and fuel consumption is displayed digitally to provide a comprehensive overview for drivers.
