Tesla appears to be working on a new app feature called Range Analysis. It appears this feature will be similar to the new Energy App that is available in the vehicle but will instead focus on post-drive analysis instead of live projected trip progress.
The new feature will break down how energy was used in your vehicle, splitting it into various components such as driving, screen, elevation, mobile app and how it compares to your vehicle's EPA estimate.
The goal of the new Range Analysis appears to be to provide a "detailed look at your recent driving behavior and to learn how your displayed range may differ from the EPA-rated range."
According to information found in the app, when you start the range analysis, the vehicle will use data from your longest drive in the last two days.
This feature is in development and does not yet have any consumer-facing components. Tesla could release Range Analysis in the coming weeks.
