I look forward to seeing what BMW has to offer in two years. I hope a 535D will sell here.

Me too, and while I'm dreaming the A6 3.0TDI or even better an A6 with the 4.2TDI would be pretty spanky.
The test report of the 535d I saw on British TV was impressive to say the least.
Of course, Mercedes has some fine TD cars too -- hope these choices soon become OUR choices.

... from time to time. Sometime these real sports cars are driven to dinner or the office at 40mph.
I am fine that you cannot accept the idea of good audio in a real sports car. Your believe and preferences are as valid as mine.
My view: These types of cars aren't always used exclusively on the track. Plus, the Cayman S isn't THAT loud (we've had one in the lab many times) when you're just tooting around town. Back when I had an NSX-T to drive, there were times when the audio system was really nice to have, and other times when it was completely irrelevant.

Noise canceling audio systems

One of the recent LPS's is selling a premium audio system that provides exterior-noise canceling in the same way that contemporary headphones do (some fancy digital signal processing). Does anyone know whether this is a trend or whether it is a curiosity? The technology makes such sense I'd like to see it in most LPS's within a few years.

There has been research that demonstrated replacing the muffler with a pipe and a speaker wired in to cancel the noise. No backpressure, or some minimum as required for the engine. It hasn't made it to production that I'm aware of. Basically, you could cancel all exhaust noise entirely if your processor was designed properly. Several cars (and not in theLPS class) have used this to save some weight (my guess). In the early 90's, Blaupunkt (sp?) announced an add-on amp that was said to perform this function on any car. I saw it at an auto show in England. I looked for it later, and I don't think they ended up producing it.
As processors become cheaper and faster, it becomes more feasible, but for something like replacing the muffler - you'd go from inaudible to open straight pipe if you blew the fuse or the amplifier. I think that may be the main reason they haven't used it. At least with a regular muffler, you usually get a heads up that the thing is about to fail.

Replacing the muffler with a noise canceler. That's really quite clever.
Of course, i see the failure issue too.

you sound like Audi...same thing they said. Not worth continuing the discussion. I can tell you Iam 44 years old and have owned Mercedes, jags, BMWs and Porsche. I know how to drive. After the first incident, I U-Turned and touched the accelerator to speed up...again off it went. Do you really think I u-turned after such a devastating event and mashed either the gas or the brake to the floor for no apparent reason. I wasn't attempting to brake nor accelerate rapidly after the u-turn. The car shot off like a rabbit a second time and red lined before cutting off. Yes, Audi said the car can't accelerate thru full braking...it can and it did. It's an event that really sucks to be honest. I've played it thru my head over and over....it's not possible I was mashing the gas. I certainly didn't do it twice because it wasn't fun enough the first time. Oh well...I've only got about 15 months left on the lease.

Dude, if you don't believe the independent experts that have tested this situation, and if you don't believe Audi and if you don't believe anybody else, then try it for yourself. Mash the brake pedal with your left foot and then try the gas pedal. A little power or a lot, it won't matter, your car won't go an inch. Still don't believe it? Try mashing both the brake pedal and the gas pedal at the same time from say 70 mph, your car will stop in a normal distance.
Like it or don't, the brakes on your A8L are WAY stronger than the engine.
Best Reagards,
Shipo
