Why do you prefer 911 over a Boxster/Cayman?

I'll start by stating that a mid-engine layout makes the most sense, and no doubt Porsche agrees, with the Carrera GT and 918 as evidence.
But I'm surprised by the Nurburgring lap times for the GT4 vs C2S
http://fastestlaps.com/tracks/nordschleife
C2S (1415 kg, 400 hp) = 7:37.90
GT4 (1340 kg, 385 hp) = 7.42.00
If the weights are accurate and I did the math correctly, the GT4 has a better kg/hp ratio (3.48 vs 3.58)
Perhaps on such a long track, 4.1 sec is a basically a tie, especially with different drivers.
But I would have expected the GT4 to not only have beaten a C2S, but to post a significantly better time.

All of which proves the point that the constantly parroted nonsense about the 991 Carrera having become a bloated GT car is just nonsense. It's faster than all the prior generations and its right there with the car that everyone begged Porsche to build. Once you set all the marketing and image aside and just look at the performance facts, the 991 is still a performance beast. And compared to the current non-GT4 981 Caymans/Boxsters, its simply a better performer.

The wheelbase is about one inch shorter. That won't add much. The weight difference is significant especially when the engine pivot point is in the middle of the car verses the end. I don't find the Carrera more nimble in slower traffic. The Cayman feels a lot lighter on its feet.

To me its Apples & Oranges. I have owned them all. Personally prefer the mid engine Cayman S design & looks until you move to a 911 GT3 version. Porsche will never make the Cayman S faster just like GM wont make the Z28 Camaro faster than a Z06. I am more concerned about P cars moving to turbo instead of N/A engines, how is the turbo going to affect the sound and drive-ability of the new Porsche's.. Cayman owners will always hear O nice car so you could not afford the 911. In the end I buy what I like & could care less what other people think, when I become concerned I will just get another Ferrari or Lambo.

But its not that significant, and its not all concentrated in the engine bay, nor is the 991 engine "at the end". When I drive mine back to back, anything the 991 gives up in so called balance, it more than makes up for in both grip and chassis feel. Where the Cayman is flighty and alive, the Carrera is buttoned down and serious. The slightly shorter overall body length and slightly lighter weight give me the perception of the Cayman being better in traffic, but it's really only perception, a result of the fact that the Carrera does everything with less drama. And the torque difference is very noticeable. That's probably the only thing that bums me out about jumping back in the Cayman S sometimes, it really has noticeably less power down low.
In my opinion sports cars should not have much torque down low, they need to be wrung out to achieve the power. That is why I love my 997.1 GT3 - if the revs are below 4000 RPM, you are hurting the engine. A GT car needs power down low, like our 991. The 991 is fun to drive at any speed, but it is a sports car a little after legal speed limits and hard corners. Anything below that it is a GT car to me, and more than a few others.

I think the car we have been asking Porsche to build is a real full powered, proper suspension, mid engine 911.
I have a 991 4S that I wouldn't trade for either the Boxster or Cayman but a true 911 mid engine with the balance and crispness of the Cayman, with full power and internals, now I'm interested

The only tool one has to feel a drive is to perceive the car's movements and tendencies. What else is there? That said, the closer the center of mass is to the pivot axis the less energy is required to rotate, also one can see how the rotational inertia of masses closer to the rotational axis behave (mid engine) versus rotational inertia of masses further out of the rotational axis behave (rear engine). It is basic physics really. The reason you perceive the better nimbleness of the Cayman versus the 991 is because it is really the case.
And 'what else there is' is the actual pace each car is able to take a very twisty road (as well as track times). Back to back on the same twisty road my Carrera S corners more quickly and confidently than my Cayman S. Where the Cayman struggles a bit for grip on turn in and exit, the Carrera just bites and goes. The Carrera just changes directions so well and in such a controlled manner. It surprised the heck out of me, as I'd read all the nonsense and drank the kool aid so to speak. But now owning both and driving them in all types of conditions, it's clear to me that reality is that the Carrera is the better sports car by a good margin. $35k better? That's for everyone to decide. And note, I looooove my Cayman.
Porsche had to build a hard core Cayman, with close to the same HP, GT3 suspension, bigger brakes, wider wheels and super sticky tires in order to just nip the 'overweight, poorly balanced' Carrera S in sporting terms.

And another point, if the Cayman actually had the same exact engine power output as the Carrera, we would not be talking performance differences in the 911s favor - especially if the Cayman acquired a real rear suspension. If we are talking performance why don't we give them both the same engine and suspension and see what happens? We shouldn't ignore the way Porsche has clipped the Cayman, the GT4 is still not a full potential Cayman. There is a reason F1 cars are mid-engined.

if looks were all I cared about, the 911 wins every time-the Cayman is a bit ugly IMO.
if performance is all I cared about, the 911 wins every time.
if money was the issue, I would buy a used 911 every time.
I would let my girlfriend buy the Boxter.

+2 I couldn't have said it better. The 911 was a life-long dream car... and now I'm driving the dream.

the Mach 3 NAA XB-70 Valkyrie, developed in the late 1950s / early '60s.....the most beautiful flying machine of all time ...nothing even remotely close to it
The plane was destroyed after the manufacturer wanted one of each of their aircraft to fly in formation so they could do a photo op. They wanted them to pull in close. They did. And the intense vortices coming off the drooped tips pulled the 104 in before the pilot could do a thing. The Valkyrie crew didn't even know it happened beyond a shudder, until it began to slew in the air and the other pilots in surrounding aircraft alerted them. One lived; one died. Two experienced test pilots killed for an industry photo op.
---Oh, right: Porsches. Yes. Like them. Prefer the 911.

You're missing my point. I'm saying that the feel and balance of the Cayman makes you think it's more nimble, when in reality it's really not. The superior chassis and grip of the Carrera more than makes up for the mid engine advantage of the Cayman.

Back to back on the same twisty road my Carrera S corners more quickly and confidently than my Cayman S.

The 991 has wider tires, weighs more, larger moment of rotational inertia, how is that nimble? Because it more low end torque it can power through its deficiencies? Is that what you perceive?
I love my 991, but I'm not going to call it nimble, at least for low speed city driving.

If it had the same power output, it would weigh more because drivetrain and running gear would have to be upgraded to handle the extra power. I suspect the suspensions will always be somewhat different because of the different engine locations. But all this is somewhat irrelevant given that we are talking about the driving experience as they currently exist.
I'm not sure why you took the time to counter my point, then deem my post irrelevant to the thread.

Actually, I think you're missing my point. Having less weight, having a smaller moment of rotational inertia will make a car more nimble. That's reality not perception.
