The M's throttle sensitivity and transmission mapping are fine tuned according to which of four driver-selectable modes is engaged via a switch positioned behind the gear lever: Standard, Eco, Sport and Snow. The Eco mode utilizes green and yellow lights on the instrument panel to provide feedback on fuel efficiency. Eco mode also introduces a new Infiniti concept known as the Eco Pedal. If driving too aggressively, the driver will feel the accelerator pedal "push back" to indicate fuel is being wasted. Sport mode changes the automatic shift points and enhances throttle response for increased performance. It will also adjust the 4WAS for a nimbler feel and raise the ESP intervention level.
