Momendo,

As AxNRocKet pointed out, I would expect straight line performance in a CVT application to always be superior to a manual.

IF (big if here) we are discussing a CVT that has a track or racing type mode, where it will hold maximum power RPM whether you are on or off the throttle, then you will have engine braking, and the ability to balance the car with the throttle.

I would have to believe that if a CVT made it into such a sporting application as an S2000, it would have to have a mode like this. If that were the case, it would most likely perform better than a manual. Would I buy one...maybe. There is still a level of involvement in shifting for yourself that would probably make me stick with the old-fashioned manual.

CVT's have been used in Machine Tools for forever, maybe Audi should ask Bridgeport for some tips. As mentioned by Pen, snowmobiles have been using them forever as well. It

older cvt are rather creapy to drive, they don't creap when you let off the gas and for anybody who has driven manual for a long time they take a lot of getting used to mainly beacause you cant judge your speed or potential for speed bases on engine noise. The worse thing is the sound the old ones used to make, it was like a whole bunch of fubber bands got stuck in the shifter and are sloushing around.

I had a '97 Civic HX w/ CVT. It worked well until about 12,000 miles. Honda had to replace the CVT under warranty. Until Honda improve their CVT technology, I would stay away from their CVT.

If you want to, test drive Honda's upcoming CVT Insight.

I hate to be the devils advocate here, but for my money I would rather have a race style, computer controlled, sequential manual gearbox like what you can get in the M3. While not as efficient as a CVT it shifts practically as fast while providing the aggressive driver infinitely superior control over over the car. I can think of many situations where I would not want the engine to be right in the middle of its powerband.
