I wanted to make sure of that, website gmauthority.com says:

Unique Valvetrain Offers More Precise Control

The cornerstone of the 2.7L Turbo L3B is an innovative double overhead cam valvetrain that enables:

• GM’s first use of Active Fuel Management (cylinder deactivation) on a four-cylinder engine.
• High- and low-lift valve profiles.
• Continuously variable valve timing.

Haha I looked it up when I read your post. I thought there's no way they use AFM on a 4 cylinder engine.
