Hi everyone

I am looking at buying an ATS awd and I like modding and am wondering which model to get. If you could do it over again, which one would you get performance wise- 2.0 or 3.6?

Thanks

if you like modding, the 2.0 is right up your alley! I ordered a 2.0 RWD premium 6mt and I have never been happier, she's almost a year old and never had one issue. there's some that have had problems, but the car is FANTASTIC! for about $320-$400 you can have an extra 30-40 whp&wtq with the Diablo tune.

welcome to the ATS side :) good luck! there's plenty of discussions about these motors with a lot of good info in them.

Have the 3.6 and I love it. For some reason majority of mods available are for 2.0. I have never seen the upgraded engine not have at least similar mods. I like the 3.6 better than 2.0T. Smoother engine, better power (stock obviously), and I like naturally aspirated. Turbo gives you power like a diesel, all of it in one lump. As soon as mods are available I will mod and review my 3.6. I think it will have more potential than 2.0T in the long run.

Had a 3.6 in my 2008 CTS so for me another 3.6 was an easy choice. Smooth running, plenty of power over a wide band, designed to run fine on 87 octane. My pickup and tractor are turbo-diesel and I will soon be adding a supercharged Corvette Z06 so I had to have something with a naturally aspirated engine besides my chainsaw :)

Some of us have had problems with the ATS. Me I have none. Love my 3.6 still. I can't really complain. Some little things but that's normal. It's just all personal preference on how each motor feels to you.

Would say a 3.6 unless you wanna take a chance and end up in the bad piston forum...OUCH! Yea I said it, but seriously its all preference. For me I almost didn't get the ATS after test driving the 2.0 but I gave the 3.6 a chance so now I drive a 3.6 ATS instead of a 3.7 Q50 (it woulda been the infiniti til I test drove the ATS 3.6). If I remember correctly they are not gonna make a twin turbo ATS-V with a 2.0....They saved that for the 3.6. So Im biased, so what? Its all in fun since I know there are modders out there with 10,000HP 2.0 turbos reading this.

I have a 2.0, I say get the 3.6. :stirpot:

More reliable, sounds better, more reliable....did I mention more reliable?

But as I said earlier, I would skip the ATS until Cadillac gets their crap together.

The 3.6 tune is available too. Not as big a gain, but it is starting with more power.

It's a shame that a good set of long tube headers isn't available for 3.6. Someone with a 3.6l needs to drop their car off with Trent for a week. ;)

I have 2.0, but I would get the 3.6 if I could do it again. I do like the 2.0, but the 3.6 models have had FAR better reliability according to Consumer Reports.

just look at the 2.0 engine failures page, at that rate we don't even need CR to see the 3.6 is more reliable :)

it's an unfortunate truth, but all I can do is hope we find out the root cause and pray mine doesn't have piston issues

We have the 2.0 and love it. Just feels lighter and more nimble. And based on my investigation, the reliability problems for the 2014/2015 are a bit overblown. We would get the 2.0 again in a heartbeat.

Re: Thinking about Ats 2.0

Drive both to see which is best for you. There obviously isn't A right answer or they wouldn't make both. If you are influenced by how the manufacturer views the topic, the November Road &Track reports Cadillac says the 3.6 is only offered in the ATS to satisfy "the displacement holdouts".

I've got the 2.0. The torque is great. Fuel mileage is decent if I drive right. I wish it had more power in the upper rpm range near the shift points. I know a tune would wake it up, but I want to avoid warranty issues. I would like to have some drive time in a 3.6, and honestly after reading about the piston failures happening to some 2.0 engines, I'm starting to wish I would have went with a 3.6. Test drive both and see what you like better.
