Whats the future of GM's 3.6L?
I think of the 3.6L as the 3.8L part 2.
Whats going on? I know they are migrating to the DI for all the models now it seems however what is the reason the CTS now uses the 3.0L as the base engine or the SRX/ equinox use the 2.8L and 3.0L? Is it emissions? I dont think it's fuel economy...
What gives? I've enjoyed every car/ suv the 3.6L has been in and find it to be a great engine.

3.6L is in the Camaro, CTS, Enclave, Acadia, Traverse, Lacrosse, and Malibu.
GM has always had multiple V6's. 3.0L with be their new small V6 while the 3.6L is their large V6. Not every vehicle needs a ~300HP engine.

There was talk of a ~330-350HP n/a V6 not too long ago. I'm not sure what the displacement would be.

Interesting article in Hot Rod Magazine on the new Mustang 5.0. Ford determined that DI saw about a 1% benefit on N/A engines and left if out, but open for adding to future turbo/supercharged versions where it would see real benefits. Perhaps that's why it was left off the 3.7L. Which again, makes you wonder what GM has in store for the LLT.

The 3.0L gets better fuel economy and has DI , over the standard HF 3.6 the CTS used to have . I dont know this as fact as to the "why's" , but the Turbocharged 2.8 IS an existing Opel/Saab engine combo , and likely why it was chosen and possibly offered more torque down low over the DI 3.6 . And as heavy as the Theta's are , more low end torque would be rather desireable .

I think the small percentage is a gain in fuel economy.

I think Ford is doing something right with PI, getting close to DI levels of power and efficiency.
