Does the AT4 have the VVT system?

We have a 2019 model and it has the sport mode. It is a great truck and I will buy another when this one wears out. Probably be a while though as it only has 41 k on it.

I was told I couldn’t order a 5.3 in my repurchase truck because they didn’t have enough available. I was offered a 6.2 or a diesel. I went with the 3.0 turbo diesel. If you get a truck with a sliding rear window keep an eye out for leaks. Mine leaked 9 times total before GM agreed to repurchase it and replace it. The new truck build has been put off twice now. Suppose to finally happen 2-7. We’ll see.

That 2020 with a 6.2 is probably not the VVT version.
