1. A system comprising:

  • input circuitry configured to receive input values for one or more hybrid vehicle design variables; and

    hybrid vehicle design circuitry configured to quantify one or more values for one or more utility/disutility variables of a hybrid vehicle design based on the input values by evaluating a hybrid vehicle model over a collection of at least one of drive cycles and routes (drive cycles/routes), wherein the model operates with time as an independent variable and uses a velocity over distance profile as an input, the utility/disutility values including at least one of;

    a total time or additional time beyond a reference time needed for the hybrid vehicle design to complete the drive cycles/routes,a fraction or number of the cycles/routes for which the hybrid vehicle design fails to achieve a target velocity, andan amount of time or distance over which the hybrid vehicle design fails to achieve a target acceleration or the target velocity over the cycles/routes,the hybrid vehicle design circuitry further configured to calculate one or more specifications of a hybrid vehicle design based on the utility/disutility values, the one or more specifications comprising a traction power to achieve a target velocity at a particular distance and specified power delivered.
