I'm trying to decide between the 3.6 and 2.0T engine. I know the 2.0T has better fuel economy but given that the 3.6 runs on regular gas vs. premium for the 2.0T I look at that as close to a wash. Obviously, the 2.0T costs less up front. But, if that upfront cost was not an issue which engine would you choose and why?

I'm sure some folks are ordering the 2.0T because they want the manual transmission. Since I want AWD that is not an option so I am interested in other reasons for choosing one engine over the other. Thanks.

I wanted AWD as well, so I decided to go with the V6. It is a little bit faster, but I think the sounds is amazing. Easily the best sounding six I've driven. I was worried I'd hate the sound coming from a C6 Z06, but it is great so far. Never feels underpowered during everyday driving. Did I mention it sounds good?!?!? I posted a couple vids on YouTube the links are in my picture thread. Enjoy!

----------

The gas mileage is in the high teens in the city. I have pretty dense traffic on the way to and from work. On the highway I get 22-24.

I opted for the 2.0T for the following reasons:
Lighter engine
Great potential for more power with tuning and increased boost
Better mpg
Personal experience with a 2.0T in my Solstice GXP Coupe

Certainly these reasons are only for me. Others will have reasons for their decision for 3.6 or 2.0T

Its an ATS. I took a listen to the video you posted of the engine sound and it does sound great. The color of your car looks fantastic too!

I too wanted AWD and believed the economy was a wash after you look at the gas prices. I went with the 3.6 because Cadillac has had great success with that engine in the past. This may be naive, but I also think there are more things that can go wrong with a Turbo.

After driving both back to back, the 3.6 sounds fantastic. The 2.0 feels lighter and more agile. Like Jim said a tune should fix the HP differential, and I hope an aftermarket exhaust can fix the sound.

You mean like stretched timing chains?

My last turbo went 280,000 miles.

I'm glad to see this discussion, it looks like there are good reasons to choose either. I ordered 2.0LT AWD about 3 weeks ago and have been wondering if I should have gone with the 3.6. I'm comfortable with my choice, but I'd feel better if it were here.

Thanks everyone for your comments. Sounds like I really can't go wrong with either engine choice. It is going to be tough to make up my mind!

Lets take this a little further. I am also looking at AWD and wonder which engine makes more sense for me.
I want AWD for winter conditions in Pittsburgh. If you don't know, think poor roads on steep hills with slick snow from temps mainly in the 20s and 30s for 4 months. But we call it paradise.
Will the different low end torque curves of the two engines effect starting and accelerating performance? I drive RWD most of the year and my Ford 4WD when really bad.
Anyone with experience able to address this?

I think if fuel mileage is not a big concern, then the V6 would be better with more weight added on the front for steering.

Can't speak about the 2.0T, but my wife's '12 SRX goes like a scared rabbit with the 3.6 AWD. Can't imagine it minus 500-600 lbs.

If your goal is ultimate power, the 3.6 is the way to go, but if you're looking for highest average power in cornering sections, i think the 2.0T has more area under the curve up to about 5k, then the 3.6 takes over. The turbo feels really lively and has almost no turbo lag.
