this is ecotec.
When in normal driving conditions, engine runs on 4 cylinders. when you accelerate, switches to the full V6. For fuel economy.
This has been around with GM for years, surprised your asking that question, almost think you were trolling for a sec. lol.

However, my 2019 RS model, does not have V4/6 in the info screens. Not 100% if the RS is ecotec or not.

Same with the V8 trucks, runs on V4 and when needs, switches to V8.

The RS has the V6/4 on the instant economy screen. Seems to only switch back and forth once the engine is up to operating temperature.

it sounds like you can only see it if you are on the instant FE screen in the DIC

The V4/V6 indication is also in the trip meters, miles to empty, etc. So odd that something like that is not on the 19.
