#49355 manual vs auto

Posted by Big Bob on 15 November 2009 - 04:43 PM

i no people say automatics are slower than manuals too 60 but parkers say some are 4 or 5 seconds slower than the manuals if its the same car which cant be right surely or are autos good up too certain speeds then they struggle as they cant do full revs?

For example mk4 fiesta 1.25 auto 14.9
mk4 fiesta 1.25 manual 11.8


As far as I'm aware man / auto rev the same, the difference is the torque converter, which is a fluid coupling between the engine & gearbox. This is where power is lost, a bit like slipping the clutch.
