So this will decrease the shift time and increase speed and accuracy of the gears going into place. Hence why it is faster when you have a dual clutch transmission car versus a manual clutch transmission car because there will be no pause and shifts will be constant and smooth.
I just remembered all the basics based on what I remembered when I watched TV about the production of the new GTR. Correct me if I'm wrong. | That's pretty much correct. The only reason the transmission is slightly less efficient is because the clutches and gears are operated by hydraulic pressure, and this takes power, even though the amount is small. Plus there is slightly higher internal friction (slight as in very small, but it's there) due to increased components. Add it up and a dual clutch transmission will transmit less power than a purely manual transmission if both are fed the same input power.
Dual clutch trannies will still provide faster acceleration though, as the quick shifts more than make up for the slight loss in power transfer. |
