1. A system for verifying use data of a configured powertrain, the system comprising:
- one or more computing devices configured to enable configuration of a powertrain, the one or more computing devices configured to;
obtain a set of specification values and an optimization goal achievable for at least one expected use value;
obtain a set of additional configuration options compatible with the set of specification values;
for each additional configuration option of the set of additional configuration options, calculate a test value associated with the additional configuration option based on the optimization goal;
present the set of additional configuration options along with an indication of which additional configuration options of the set of additional configuration options are associated with a positive test value; and
cause the powertrain to be configured according to one or more additional configuration option selections received by the computing device; and
a vehicle comprising the configured powertrain and an electronic control unit (ECU);
wherein the ECU is configured to;
obtain use data comprising at least one of vehicle speed data and engine speed data; and
output the obtained use data for comparison to the at least one expected use value for determining whether actual operation of the vehicle is consistent with the expected use value.

Abstract
A powertrain optimization device and method that compares a predicted performance of customer-selected vehicle components to a customer-selected optimization goal. The optimization goal is used to determine dynamic performance thresholds. The method compares gradability at cruise, gradability at peak torque, engine speed, and startability to the dynamic thresholds to determine whether the vehicle performance will be satisfactory. The customer selections of vehicle components, selections of optimization goals, and any acknowledgements of failed performance checks are stored for later use.
