Isn't that what they said when the automatic transmission came out?

Slush boxes have performance and effiency downsides, PDK has none (as long as they don't blow up).

I understand your point, but dual clutch systems are:

1. Heavier than manual counter part
2. More difficult and expensive to repair (so far)
3. Have more parts subject to potential damage wear and tear.

I don't know...you have a GT-R...it's obvious that you really like it. I think dual clutch technology is still in its infancy for mass produced cars...it may ultimately be the future, but I'll wait for the kinks to be worked out.

Another note, where is the power at lower and mid rpm??? I only could feel the 385hp above 6000rpm...
Riiiiiigggghht. You must be one of the most in tune drivers of all time.

If this transmission is so bad, why is the GT3 RS going to have it deployed?

1: Well worth the weight in terms of performance gain. Faster and better mileage. Minor cornering impact more than offset by benefits, so non-issue

2&3: You could say the same about early turbo systems, variable lift valves, AWD, etc, etc. Just give it time. Even despite all the hype (even including the GTR stuff), I think these systems ARE ready for prime time.

Chris, you just proved my point for me. Early turbos, AWD, etc all had kinks to be worked out...they have evolved to be extremely reliable systems. Every double clutch system...e-gear, SMG (every version), and I predict PDK, will go through growing pains. When the kinks are worked out, and I can get 30-40K non abusive miles out of them, then I'll agree with you.

This isn't even going into the argument about modifications. I have no doubt that in its current state, a manual clutch system will tolerate higher levels of modifications than any double clutch system currently available. And while we both have different opinions about the GT-R, you have to agree that creating high HP car will be much easier and cheaper to do with a manual transmission car.

one thing i think is true-they just gotta get the shift levers off the steering wheel and onto the column, so that you can actuate it when you turn the wheel-i think that is an absolute.
