what's faster, an automatic or a manual?
So, i was under the assumption that a manual transmission would prove to be a faster car (in terms of acceleration) because there is a direct connection between the clutch and the fly wheel, whereas an automatic transmission works on the basis that it slips when shifting between gears. but then my dad told me that 95% of drivers driving an automatic would be able to beat someone driving the exact same car but as a manual, simply because you can not shift a manual shifter as fast. (the other 5% were the drivers that did not care about the clutch and speed shifted between gears). Then i realized that my automatic is a 4 speed, so if i were to be racing a manual version of my car from 0-60, i would only need to make 2 shifts because my car can get to about 65 in 2nd gear. the manual car would most likely have to shift 3 times because the gears in a 5 speed cover a smaller range of speeds. so, wat's faster?
A new gearbox that is showing up on more and more cars is an automatic with dual pressure plates. When it comes time to shift, instead of having to disengage the lower gear, spin down the power shaft, and reconnect at a slower engine speed, the dual shifter has two gear shafts. While the lower gear is driving the wheels, the next gear is engaged and spinning on a second shaft. When it is time to shift, the transmission switches pressure plates. Shift time is reported to be 0.04 seconds. Volkswagen calls this the DSG transmission, and I have seen Porsche advertise the same thing.
So, now, instead of burning up manual transmissions. leaving the engine on high RPM and pressing the clutch in only for the final throw into the new gear, you just switch transmission shafts electronically.
I did have a '56 Olds with a bang shift hydromatic transmission that could get 3rd gear wheel spin, but it was way too heavy to race anyone.
