I was browsing the papers the other day and came across an ad for a car. One of the features of the car is "Double Clutch".
I was curious. I just got my driving license. And I took manual for my pass.
And no matter how I looked at it, there is only one clutch and one stick for the gears. Where comes the double clutch?
Do you have any idea what the double clutch is referring to?

ahgong,
The double clutching technique involves the following steps:
* The clutch pedal is pressed, the throttle is released, and the gearbox is shifted into neutral.
* The clutch pedal is then released. As the engine idles with no load, the RPM will decrease until they are at a level suitable for shifting into the next gear.
* The driver then depresses the clutch again and shifts into the next gear. The whole maneuver can, with practice, take no more than a fraction of a second, and the result is a very smooth gear change.
It is basically a driving procedure primarily used for vehicles with an un-synchronized manual transmission.
Hope this will clear the air for you.

hmm... stepping the clutch twice during gear change.
This will ensure a smoother gear transition?
Must give it a try to know. Mabbe the next time I get a car, I will try getting a manual one. Then give this double clutch thing a try to see if the gear shifting will really be smoother!
So far, my wife keeps complaining that my manual gear shifts skills are crap! 
So have been driving autos so far. And autos are really a breeze to drive compared to manual!

ahgong,
Autos are indeed handy during peak traffic congestion but other than that you can never be able to enjoy the feel and control from a manual which I prefer and enjoy.

If it's the New feature available on some cars (VW?)that you're talking about,this is an extra mechanism in the clutch assembly that helps speed up the gear selection process so the gearchange goes faster..it doesn't mean you need a second clutch pedal!

If You know the particular car maker's website (I recall reading about this feature on the VW Golf car a while back,which is why I mentioned it-other makers may have this technology) that would probably be the best place to look for information about features like this..I just like to be aware of what's coming next in technology,and would only have basic knowledge on the subject.good luck with your interest!

yeah. most of the time cars dont have double clutch. or you dont need to double cluth a car. most of the time you have to double cluth like big trucks such as dump trucks, and tractor tailors.
its basicly is where when you are shuffy and you go up a gear or down a gear you have to push ther clutch in twice..
