Not sure if it is gear driven or if there is an electronic way of doing it.

Speedometer
ECM calculates vehicle speed using wheel speed sensor signal from ESP® control module and sends vehicle speed signal through CAN communication to combination meter.
So does that mean it will self calibrate?

No, because it will be calculating based on the standard wheel diameter

The Gen4 is a twin double sensor (four in total) system whilst the Gen 3 is a single sensor system, therefore this kit would not work
Sorry, I assumed the system was similar with a single dedicated sensor for the speedo.
I guess that due to the extensive electronics providing the ESP (Electronic Stability) they need redundant double sensors and then two of them to compare front and back
