1. A system configured to detect excess fuel consumption in a vehicle, the excess fuel consumption detection system comprising:

  • an engine computer system including one or more vehicle subsystem sensors configured to generate output signals conveying vehicle feedback information related to operation of mechanical systems of the vehicle;

    one or more external supporting sensors configured to generate output signals conveying vehicle environment information; and

    one or more processors configured to provide information processing capabilities in the excess fuel consumption detection system, the one or more processors configured to;

    determine one or more vehicle parameters based on the vehicle feedback information and/or the vehicle environment information, the one or more vehicle parameters indicating one or more vehicle characteristics;

    electronically store the determined one or more vehicle parameters;

    detect a vehicle maneuver associated with excessive fuel consumption based on the determined one or more vehicle parameters, wherein the detected vehicle maneuver occurred between a maneuver start point and a maneuver end point;

    determine a target fuel consumption amount for the detected vehicle maneuver by estimating an amount of fuel that would have been consumed by the vehicle at the time of the detected vehicle maneuver if the vehicle had been operated so as to prevent excessive fuel consumption, wherein the target fuel consumption amount is determined based on the detected vehicle maneuver and the determined one or more vehicle parameters;

    determine an actual fuel consumption amount for the detected vehicle maneuver based on actual fuel consumption that occurred between the maneuver start point and the maneuver end point;

    determine a consumption difference between the actual fuel consumption amount and the target fuel consumption amount; and

    effectuate presentation of the consumption difference to a user.
