I feel compelled to point out, that, yes, but the TTRS has smoked the Cayman R (the fair comparison) around any track they've both been measured on, despite any weight disadvantages, or so-called "trouble with the curves."
I feel compelled to point out that you're wrong: Nordschleife Lap Times
As you can see scrolling down, the Audi TT RS Coupe is 8:09 and the (old) Cayman R was 8:06. But even more impressive is the new 2013 Boxster S, which has come in at 7:58. With the weight reduction and chassis improvements, I expect the new Cayman being somewhere between that time and the 7:37 posted by the new Carrera S. My bet would be 7:48 for the Cayman S.
But I don't need to go to Germany with a racing helmet to form my personal opinion. Even with moderately vigorous test drives, I have felt the weight and bulk of Audi's. For a big luxury sedan like the A8, not a problem. For an A6, a little more so, for the S5, it didn't feel as nimble as a 335is or M3. The TT S (I haven't driven the RS), was not as rewarding to drive as my old S2000, let alone a Boxster S or Cayman. It has a great looking interior and probably is the most comfortable with cruise control on at 75 mph on the highway, but that's not the top of my priority list for a sports car. BTW, I am even more critical of the BMW Z4. The make a great diesel SUV, as my garage can attest. But not a very compelling so-called sports car.
I understand Audi has elected to go with AWD as their preferred performance drivetrain. It certainly beats FWD to death. But it adds weight and takes away the nimbleness of RWD when you get into the sport sedan, coupe and sports car categories, IMO. I'd make the same claim relative to Porsche. Give me a GT3 over a 911 Turbo any day. Or if you are feeling really generous, a GT2.
P.S. Price vs. Weight. Yes, I agree with a previous post that Porsche has a few more engineering dollars to spend to squeeze out more weight. The point I am making is that right now, Audi doesn't seem to think that weight is a problem, period. That's an attitude issue, not a cost one.

Apples and oranges. Complaining about extra 200-300 pounds
When creature comforts started taking over cars, they will get heavier. back up camera's, Nav system, Infiniti adjustment power seats, quieter highway cruising.) Also look at the safety equipment that cars have to have, air bags, safety glass etc..
Of course car companies can build the extra light weight sport car with no thrills Honda S2000, Cayman R (2855lbs) or how about the Honda/Acrua NSX (2975lbs) Porsche knew what lightweight was in 73-74 when they built the 911 RS 2175 lbs (this was the SL (superlight) weight)...
The question do car companies want to build them? BMW had the The BMW M3 CSL (Coupé Sport Leichtbau) weight 3050lbs (light for BMWs) I'm sure BMW could have shaved off an extra 200lbs from the car, but elected not to. Wouldn't be nice to be able to buy a BMW 3M coupe, at 2800 lbs, making 330hp, or better yet, just a 3 series sedan or coupe CSL...

When I read your reference to the 911 RS, I realized that I'm probably guilty of taking this discussion too far for the ELLPS forum.
I had originally responded to another post suggesting that Audi is in the engineering leadership position. I agreed that, while they make some very nice cars, they could use a dose of attitude adjustment and make weight loss a higher priority. Across the board. That doesn't mean I think they should shoot to compete with 1970's vintage sports cars. But almost every vehicle they have now competes for the title of "heaviest in the segment". The Q7 was by several hundred pounds the heaviest SUV we considered - even though it has a smaller interior than the MDX. That excessive weight made it feel slow and ponderous handling compared to the X5d, Cayenne and even their sister Toaureg (which is no lightweight either). Lost sale relative to us, given that it is otherwise a fine vehicle.
We can take up on another sports car board whether Audi has been too pig-headish on maintaining AWD as their only drivetrain on their TTS, S4/S5 and other performance models. But you will never get a TT anything to feel as tight, sharp and visceral as my old S2000 with the extra weight of a water buffalo in the passenger seat. Maybe a juvenile buffalo, but a buffalo all the same.

Blame not car companies. Blame our litigious culture resulting in the heavy (literally) safety mandates (often overkill or just nonsensical). Blame also a dumb consumer car culture where cupholders and stereo take precedence over driving dynamics even in the so-called "enthusiast" segment.

The "creature comforts" of nav, power windows/locks, power seat adjusters, soundproofing add very little weight in relation to the manual systems they replaced. Especially with todays mini electronics and motors. Soundproofing is not the heavy stuff of bygone years either. The culprit in weight gain is safety systems in response to federal regulation and insurance industry standards AND the overall size of the vehicle. While you can add high strength steel in the framing and aluminum hoods, etc which can save a few pounds, physics will not be denied and the weight goes up somewhat relative to the increase in the size of vehicles.
Just look at tires. My first car had 13" and even 16"s were large throughout the 90s. Now the the standard is about 17" with 18"s pretty common as well. Can't tell me that these larger wheels and tires don't add significantly to the weight.

I think that is mostly correct, but it would be interested to see where all the weight is if you pulled a couple of cars apart. Here's three I'd start with:
1995 Maxima SE 5-speed manual: 3,001 lbs with 3.0 6 cylinder engine. Length 187.7 inches; width 69.3 inches.
2013 BMW 328i 6-speed manual: 3,360 lbs with 2.0 4 cylinder engine. Length 182.5 inches; width 71.3 inches. AWD/Automatic: 3,595 lbs.
2013 Audi A4 FWD CVT: 3,509 lbs with 2.0 4 cylinder engine. Length 185.1 inches; width 72.2 inches. Quatro: 3,616 lbs.
Wheels and tires have gone from 15" 215 series on Maxima to 17" 225-245 series on Audi/BMW. In fairness, the Maxima has gone up to 3,551 lbs, and is now 190.6 inches long and 73.2 inches wide. That's A6/535i size, both of which are pushing 4,000 lbs. Also, in spite of the greater exterior width of the A4 and 328 compared to the older Maxima, the interior width (shoulder/hip) is almost identical. Much of the exterior width difference is in flared fenders and design elements.
I don't think we should go backwards in structural rigidity and crash worthiness. But I have to question how much that accounts for the significant weight increases since the mid 1990's. You can have very light safety cages that can withstand tremendous stresses, as Formula One proves.
Oh well, I'm up about 10% in body weight since buying my 1995 Maxima. I'll get that down to 5% before I complain on this subject again. Hopefully, before Thanksgiving.

Sorry guys for my lack of precise knowledge, so please just bear with me.
I think I remember reading somewhere that the reinforced cages added weight significantly (new materials notwithstanding, or maybe because of their higher costs?); in particular, new requirements on the roof strength in case of rollover raised the center of mass and changed the vehicle balance and handling, which in turn was one of the reasons to mandate the electronic stability control. FWIW. I don't know about you, but I would take an active safety over passive any day. I am concerned much more about the capacity of the car to outmaneuver and avoid an accident than about it saving my a** when the accident happens.
You are right about tires, but maybe the difference is less than it appears from the rim diameters. The overall wheel diameter is probably not much more that it used to be. In the past, high-aspect passenger tires were the norm, while now low-profile (such as 45-50) tires are ubiquitous even in the "family" sedan category.

Regarding your observation that "Audi has been too pig-headish about maintaining AWD . . . on their . . . performance models." I have no real proof (other than what I read in Car & Driver, et al) of my observation that Audi has built its reputation on AWD (at least in the US, if not elsewhere) and it has, of course, marketed itself, trademarked, copyrighted, and probably patented its "image" (if possible) on quattro and "The Four Intersecting Rings."
Audi has labored and fought hard to be equated with "quattro" just as a famous cola manufacturer has fought hard to be called Coke; or as hard as a tissue manufacturer has fought to be called Kleenex.
If Audi reverted to FWD instead of AWD several things would happen and not many of them would be good (at least from both marketing and performance perspectives). And there is no way I [at least] could ever imagine Audi marketing RWD cars -- any more than Coke wants any cola product to be called coke (with a little "c").
Audi would also probably point to near premium, premium, and super premium (and exotics, too) cars that are all-wheels-driven vehicles.
Several of the world's greatest automakers save AWD for their highest performing models. Perhaps AWD is in Porsche's blood what with Audi, VW and Porsche all being related. Perhaps Lamborghini too has AWD in its blood due to Lamborghini's relationship with Audi. The same for Bentley.
Audi would probably argue that AWD is their performance vehicles' "secret" [not really secret, of course] weapon or sauce as the analogy might go.
I love the use of the phrase "pig-headish" -- and assume it was meant to be ironic or at least be a double entendre since Audis are "front end" (or head end, as opposed to butt end) heavy.
I just don't see Audi doing anything else than continuing to embrace AWD -- especially for its highest performing cars.

Victor, litigious culture is correct, however, if car companies would build a super light version of a M3 or A4 in a small run to give the driver enthusiast what they want. I would have to say that i highly doubt the average BMW 3 series driver wanting to buy one of those, As stated before, you can have a light weight car, but do the car companies want to build them? When BMW built the M3 CSL it was sold out before the production run started, Porsche does not have a problem selling their Cayman R either. It seems selling the cars isn't a problem..

That will get the blood boiling with a lot of Porsche enthusiasts that are far more knowledgeable and much more proficient sports car drivers than me. I've been casually shopping for a replacement for my 911 C2S that I sold 18 months ago. In the process, I've attended a Porsche track event and test driven several cars, new and used. The conversations I've had with Porsche employees, enthusiasts, and professional drivers has been pretty educational.
Bottom line, very few serious Porsche enthusiasts consider the 911 Turbo (AWD) to be the pinnacle of the 911 line. They put the GT3 RS4.0 on top, GT3 next followed by GT2. Some would put the new 991 C2S ahead of the 997 Turbo. They like naturally aspirated engines and RWD. The GT2 is the RWD answer to the Turbo S, and is fast as hell, but not preferred by them over the GT3.
The AWD 911 Turbo and various "4" cars were, as explained to me, partly based off the fact that the 911 RWD has a front/rear weight balance of roughly 37/63 and some buyers liked having another 150+/- lbs over the front wheels and some extra grip. That was usually followed by a thinly veiled "amateur" adjective to further describe that type of buyer. But not the preference of the serious enthusiasts, it seems. As a matter of fact, I have heard from several that they have acquired 993 Turbos (last of the air cooled engines) and actually disconnected the front drive train to make them RWD.
The Cayman and Boxster will never be AWD. They are already perfectly balanced and light.
My pig headed comment was probably unfair. Audi has built quite a reputation on Quatro. But remember, they started out as FWD, which is the worst of all worlds, so AWD was really a necessity if they didn't want to fire all of their engineers and start over. A RWD TT RS is probably not in the works, and the fact that the heavier AWD TT RS has none of the feel and sharpness of a Cayman S or R is probably not important to the typical Audi customer. But it would be to a Porsche enthusiast.
