What is “intelligent driving”? At Mazda, we consider “intelligent driving” to be that which is fun for the driver, yet considers the comfort of passengers as well. As a bonus, such driving also leads to improved fuel economy. Mazda’s Intelligent Drive Master (i-DM) is a system designed to help you improve your technique and driver more “intelligently.”
As the driver controls the car using the accelerator, brake and steering wheel, the bodies of the occupants will move and sway in response to the vehicle’s movements. Using an onboard computer, i-DM employs a spring-mass model to calculate these body movements based on vehicle speed and steering angle inputs. These computed body movements are used to evaluate the driver’s driving style, with the results displayed in real-time using a system of blue, green and white lights.

In addition, the system allows drivers to check their overall driving score, either at the end of each drive or even part way through. This allows drivers to keep track of their progress.
