C6 Corvette Z06 will plant you in your seat.

 

I am not really sure what are you describing. The 911 feel is totally different than Cayenne and to most it's much better, but if not to you, then that's what matters!

Maybe on Turbo you were getting a bit of turbo lag, however, the power after turbos kick in is insane... so not sure what you mean it didn't feel fast.

I think this explains it. The car is PLANTED and doesn't have the same kind of weight transfter in Cayenne, or CTS-V, which may explain the feel, and it is MUCH SUPERIOR fundementally, as the weight is mostly behind you.

It doesn't sound like you're much into racing... so as others said, you need to buy what FEELS BEST to YOU! on the street. Don't worry about brand, HP, what forums people say, etc... just get the car that put the most grin on your face. Any of the cars on your list is superior to 90% of the cars on the streets.

 

I like cars that when you accelerate make you feel like you have to grip the dash and hold on for dear life even though your really not going that fast. The weight transfer and body roll has to be significant enough to whack a passenger's head into the side window and force the tires to scream when making even a slow corner entry feel like it was taking like a race car driver would.
I guess the Turbo just isn't the car for me. /end sarcasm

 

All sarcasm aside, some of the most fun I have in my cars comes towards the end of the useful life of the tires when I've got no grip and I can slide through any corner even at 15mph. There's a lot to be said for low limits and driving entertainment. I can see the issue from both sides.

I think Alex has got it figured out -- the rear-engine design of the 911 is intended specifically to eliminate that see-saw squirminess off the line. If a driver has come to associate that specific sensation with performance a 911 is apt to feel oddly sterile and underwhelming.

It reminds me a feature in modern telephones called "comfort noise generation." With voice over IP and digital audio for telephones, silence truly is silence -- dead air. When the first digital phones hit the market people were uncomfortable with the total silence, thinking the call had dropped. Modern phones introduce some fake noise into your calls, reducing fidelity and sound quality, but eliminating that discomfort and confusion from people with decades of expectation that phone calls are sort of noisy. CNG makes worse phone calls that feel more "natural" and comfortable for callers. It's a worse call, technically, but nobody asks "are you still there?" every few minutes.

Or similarly how PDK in sport mode intentionally makes the shifts a little bit more jarring, not because that's faster but because people's experience with torque converters and manual transmissions makes them associate jerky shifting with fast acceleration.

 

On this note -- I don't know which corner of Texas you're in.

I'll be at MSR Cresson (near DFW) the weekend after next (23rd/24th) and Eagle's Canyon (also near DFW) on the 25th.
I'll be at H2R (south of Austin) November 20th.
Not sure when I'll be back out at MSR Houston or Texas World Speedway (College Station).

If any of those dates/locations align with your schedule, drop me a line.

 

I'm in the DFW area and the 25th would be awesome. I'll send you a private message with contact info.

 

As a fellow instructor, I'm glad you're taking him up on the offer, I think it will open your eyes. Please share your thoughts afterwards.

 

The reason that PDK shifts in sport and sport plus are sharper or more "jarring" as you put it, is because while in normal mode, for greater comfort, engine torque is reduced when shifting, in sport mode it is reduced only slightly, and in sport plus it's not reduced at all. Since there is little or no reduction in torque, performance is, in fact, improved by this shift strategy. This info is paraphrased from the 2009 Porsche Technik introduction for the Carrera.

 

Ah, excellent. Thanks for the correction.

 

Yes good points. Turbo is insanely fast for a road car. Was just compared equally "insanely" fast to the 959; same word "insanely" also used by reviewer in a review recently posted. "Insane" fastness is the opposite of OP saying it "didn't feel fast."

Conclusion: So-called sanity aside you (the OP) need not worry about what people say in these forums. You (the OP) should get the Cadillac.

(joking . What I really mean: get what you want and be happy! )
