Add New GM 2.7L Turbo Engine

[PrimePWR]

How do you add a new, first of kind engine as an option for a vehicle?

I'm truck shopping and wanted to research how new drivers of the 2019 Chevy Silverado 1500 or GMC Sierra 1500 with the first of kind 4 cyl 2.7L turbo engine are doing with real-world MPG.

This made me realize that the option for this engine is not yet available in the system for the driver to choose, which is probably why no data yet exists.
