I very much agree! I too traded my 2014 TT for a 2017 TTS and the performance difference is very noticeable. The acceleration (seat of the pants measurements) just seems much stronger in sport mode (even while keeping the RPMs below 4K) and the braking is much improved with CCB (I just hope I never have to replace them).

This to be true, but this is comparing a 991.1TT to a 991.2TTS, and the 991.2 has numerous performance enhancements including higher horsepower, torque, and EMU tweaks, among others, so the performance difference would likely be noticeable. However, the question on some minds is -- what's the difference in performance between the current generation 991.2TT versus the 991.2 TTS. Zero-60 improves by 0.1sec on the TTS. With that in mind, I thought the Turbo would be adequate for my needs -- that's what I ordered.

If you don't want PCCBs and center lock wheels, a nicely optioned Turbo could be a better value. I have a '15 non-S and the only option everyone says is "must have" that I lack is PDCC. I didn't really miss it until a track session, when I found that it was hard to manage tire temperatures, as there seemed to be uneven tire loading once you start driving for extended periods at 8/10 or 9/10s. This might have been helped by PDCC. Otherwise, a $160k car with everything else I want doesn't seem a bad deal.

At the time I purchased, my new '15TT had an MSRP of $172.5....TTS cars I was looking at were about $10K -15K more.
I did not want center locks (5 lug were avail on TTS and a N/C option but there were none in my region) and
the other things that were standard on the TTS v TT made no difference to me. Performance wise I could tell
-0- difference driving both back to back.

Having no "S" on the back bumper means squat to me...."lesser badge" envy ha ha

Doing a couple thousand $$ Cobb/GIAC tune on the '14 to '16TT models erases any power difference between the two
if you are so inclined to do one....for me the TT was a bargain in comparison.

RE: '14 (incl '15 & '16) Turbo v TURBO S:
Excellence Magazine article - 12/13 issue (pp 62) interview w/August Achleitner, director of 911 product line -
stated that the 991 thicker piston crowns compared to the 997 Turbo were changed in the 991 Turbo to
withstand "greater combustion pressure" w/no change in in the 9.8:1 compression ratio.

Additionally goes on to say the '14 Turbo S motor is MECHANICALLY unchanged from the base Turbo,
relying purely on an ECU software remap for its extra power & torque.

I really like the look of the CLs, but don't want them. I like the lower, though considerably more frequent, costs of replacing my brakes and no risk of squeaking. I can count on one hand the number of times other than the track I've been able to safely use the measly 540hp I have, and probably couldn't tell the difference at 0.1 sec to 60 from the extra 40. If I ever get bored (which can happen when you get used to more power), and when the warranty runs out, I'll find myself on the slippery slope but with first improvement being sound (both exhaust and Bose). I might have paid up to an extra $10K for bragging rights with the S, and it is certainly arguable that resale might be relatively stronger, but this is not part of my investment portfolio

I specifically wanted a turbo, not an S, as I do a lot of track events. Which means you don't want a) PCCB and b) center lock wheels.

I do however have PDCC on my turbo, which I think is a very cool feature.

Concur on the PDCC! I love it. I wished I'd had it on my Panny turbo back in the day. I loved that twin turbo V8. Now I love the twin turbo flat six.

I didn't need PCCB or centerlocks, but I wanted the Burmester, which I do not regret.

Truth be told, the 991.2TT is the same performance (even slightly better in some cases) than the older 991.1 TTS.

+1 Very cool re PDCC. I've since added a DSC v.2 controller to my car, which lacks PDCC, but gives me pretty much the same results as if I had PDCC.

On the .1 cars, the Turbos are the same size but there's an ECU difference which I think leads to a redline rpm difference as well. But as far as piston design, fuel injector design, turbo impeller size, etc. I think they are the same on .1.

Now on .2 cars, the S has larger turbos.

Several items that are standard on the TTS are not on the TT - if you want those options (PDCC, carbon interior, PCCB, CL, etc.), then there is some savings by moving to the TTS vs ordering a la carte. You also pick up 40hp for free. This is the primary reason the TTS outsells the TT. As mentioned above the kicker for 991.2 TTS is new, larger turbos, which further differentiate the TTS from TT from 2017 forward. Those differences and the much lower production of 991.2 are the cause of the price separation between the 991.1 and 991.2 TTS.
