Powertrain optimization mobile application

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by one or more processors, cause a mobile computing device to perform actions comprising:

• presenting a first set of one or more user interface elements on a display of the mobile computing device;
• receiving user input corresponding to a set of one or more vehicle specification values via the first set of user interface elements;
• obtaining a vehicle performance value, an optimization value for the vehicle performance value, and vehicle specification analysis information based at least in part on the set of vehicle specification values;
• and
• presenting the vehicle performance value, the optimization value, and vehicle specification feedback on the display of the mobile computing device,
• wherein the vehicle specification feedback is based at least in part on the optimization value and the vehicle specification analysis information, and wherein the vehicle performance value is a fuel economy value or a greenhouse gas (GHG) emission value.
