So, yesterday I drove a 2015 Cadillac ATS AWD 3.6L 6AT coupe with 68k miles on the clock. This car had a bit of hail damage on the hood, but overall it appeared to have been very well taken care of.
Overall, it's a good car. My wife loved it!
I'll start off with the interior: That car has a tremendous amount of legroom. Probably more than pretty much any car I’ve ever driven, ever. The seat bottom/thigh support also extends- but not nearly as far as the BMW’s sports seats, which extend an extra 1-1.5 inches further than the ATS' seats. I started my test drive out with a position that was closer to the steering wheel, so my arms were in a good driving position, which ended up causing me some knee pain... so, as the drive progressed (I probably spent ~45 minutes driving it), I kept moving the seat back and the craziest thing happened: the knee pain went away entirely. That’s never happened before. The legroom in the car is truly incredible and makes me wonder: why can't other cars follow suit?
Unfortunately, with the seat far back enough for my legs, the steering wheel was a very far stretch, which made me feel like I had T-Rex arms stretched out so far that I couldn’t comfortably pitch the car around. Not a problem for cruising and not a deal breaker, but the wheel should have been able to telescope another 1-2 inches, like my BMW. Matt Farah complained about the exact same thing- and he was right. For reference, I'm 6'2", 217 lbs, 33" waist and 34" inseam. I believe Mr. Farah is about 6'3" and a good bit heavier than I am. For shorter drivers, this likely won't be a problem. Yes, the steering wheel was fully extended.
This car has a ton of headroom and great visibility. Granted, this particular car didn't have a moonroof, but nonetheless, it had enough headroom that I don't think it would have mattered. Overall, I felt like the car had plenty of space in pretty much every direction. The back seats weren't huge, but fitting a smaller adult back there would have been just fine.
The seats are adequate. Sitting in them, they’re pretty hard/not very cushy, without much bolstering, so I slid around if I tried to take a corner at speed. This is surprising, as I remember the seats in the "lowly" Camaro being far more comfortable and supportive. I drove my 128i down there, with both my wife and I agreeing that the BMW's seats were softer, more comfortable and far more supportive. The rest of the interior was nice, but the touch screen infotainment was rubbish and difficult to use while driving. I can see why everyone hates Cadillac's CUE system.
The ATS 3.6L V6 is not fast, but with 321hp (bumped to 335hp in later years), she’s plenty peppy. The transmission is also fairly responsive (much better than the G37/Q40's 7AT). More than adequate power for passing. The transmission isn't as clever and responsive as the ZF 8-speed in modern BMW's and Chrysler products, but it's adequate and I didn't have many complaints about it. I believe the later (2016 maybe?) models got an 8AT, which might be more responsive, but I can't comment on that, except to say I didn't really have problems with the 6AT for daily purposes- it was just fine. Nothing impressive, but perfectly adequate.
Overall the ATS has very responsive steering and a very solid chassis. I know it's built on the same super stiff Alpha chassis as the Camaro and you can feel the rigidity- it's like it was hewn from a solid block of aluminum. At around ~3600 lbs (in V6 AWD trim), she's not a light girl, but she actually hides her weight very well, feeling like a smaller, lighter car. Being an EPS rack, there's not a lot of steering feel, but I felt like the rack was very good for an EPS car- very direct and well weighted. The weight of the wheel is not excessively heavy as to be laborious, but not too light to the point where it feels darty and lacks feedback - the Goldilocks of steering weights. Solid work, Cadillac.
Body roll was minimal, with the car being very eager to change directions, without feeling like it was going to get away from you. If it wasn't for the seating position, it would have been very confidence inspiring to pitch around. The ride was certainly firm, but not what I would call harsh. I would have no problem taking this car on a road trip, soaking up all the miles.
For something in this genre of cars, I felt like the ATS was the right size. Small enough to get through traffic without much of an issue, but big enough that it doesn't feel cramped in the least.
This isn't what I would call a crazy fun car, but I think it would make an excellent daily. My biggest complaint was the awkward seating position with the seat back far enough to quell the knee pain. Being so far away from the steering wheel, I didn't feel confident in controlling the car. I think that took away some of the fun factor for me. I don't think a shorter driver would have this problem.
I deliberately sought out a 3.6L V6 to drive. Most of these cars are GM's 2.0L turbo, which, at my elevation, would have probably felt a bit more mid-range torquey (even though I didn't have a problem with the 3.6L)... but I haven't seen people having many problems with GM's LF/GX V6 on this platform, whereas there appeared to be a few issues with the 2.0T that I wanted to avoid.
If I was shopping between the ATS and the Infiniti G37/Q40/early Q50 3.7L, I think I would get the ATS after driving them both. I think the biggest detractor from either of them would be the E90, which is in an odd spot. The E90 undoubtedly has better steering and ergonomics, but there's a trade-off. These cars, in AWD sedan trim are all of similar sizes and weights (3600-3700 lbs). The ATS and Infiniti's have bigger V6's, making 320-330hp... whereas something like a 328xi is comparatively underpowered with the 230hp N52 I6. Don't get me wrong, the N52 is a great engine- smooth as butter, sounds better and has a very linear torque curve... in my 128i 6MT, the N52 is great! But when placed in a 328xi: the 328xi adds 400 lbs of weight, AWD drivetrain loss and a power robbing slushbox... Which leads me to believe: I don't feel like the power would be adequate.
I used to own a CPO'd E90 335xi many years ago. Under warranty. Power was not an issue in the least. But stepping it up to an old E90 335 is a tough sell, as the N54/N55 require far more wallet-breaking maintenance than the N52 cars. Based on that alone, I think for a reliable daily, the ATS or Infiniti 3.7L cars are a smarter choice. Hence why I haven't looked into an E90. For whatever inexplicable reason, I'm just not terribly interested in the F30.
With that said, I think I'm going to hold off on buying something like this. My shoulder is healing up nicely and I drove my BMW down there... When I was done driving the ATS, I got back into my 128i and after pondering a bit on the drive back home, I wasn't convinced that I would actually drive it as much as I drive the BMW. The BMW is just very good to drive- it's more fun and more comfortable. I'm not convinced I would get much use out of the Cadillac. As such, as of right now, I can't really see the value in it and will likely pass.
New plan, Version 9.76.1-E: sell the Integra (I don't drive it anymore) and just keep driving the other cars I have, which are all really only driven on the weekends. Keep the money from the Integra sale in the bank. If I find myself really yearning for a nice automatic cruiser, buy something more like this. Or if I switch units at work and end up without a take-home car (rare possibility), then look into an automatic for traffic purposes. Otherwise, accept that I have the cars I have for a reason: there's nothing else within reason I would rather drive for the money. It only took several months and countless test drives to figure that out. What can I say, I'm a slow learner.
