Guest funkywim Posted January 16, 2012 Share Posted January 16, 2012 I was wondering , how do professional racers shift ? In formula 1 cars they use flappy pedals , but in time attack ,gt1 , formula d ,... they always pull a lever when they shift up and push the lever when they shift down . What i was asking myself is , in allot of porsches and other cars you have tiptronic , where you also pull and push the lever , now in those cars they don't have a clutch . So my real question is : do professional racing cars use a clutch or the tiptronic system ? Anybody who knows ? Quote Link to comment Share on other sites More sharing options...
nige-rz Posted January 16, 2012 Share Posted January 16, 2012 Willing to be corrected here, but in F1, I was of the impression they had a hand clutch on the steering wheel? Quote Link to comment Share on other sites More sharing options...
Guest ugp Posted January 16, 2012 Share Posted January 16, 2012 If you mean on a sequential box, like a motorcycle, then no, you do not "need" to use the clutch, although it is recommended if you're cack handed Quote Link to comment Share on other sites More sharing options...
Guest ugp Posted January 16, 2012 Share Posted January 16, 2012 Willing to be corrected here, but in F1, I was of the impression they had a hand clutch on the steering wheel? Nope, all electronically shifted now. Buttons on the steering wheel operate solenoids on the box. Quote Link to comment Share on other sites More sharing options...

Driving an F1 car is easy so, it's and automatic But, did you see the Topgear episode where Hammond kept cutting out? Surely that car wasn't electronically shifted?

That was and old F1 car though in that so it might have had a clutch as you said earlier. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 16, 2012 Share Posted January 16, 2012 F1 cars have 2 hand clutch settings, one for complete disengagement and 1 for starting. Modern sequential boxes all work on hydraulics and computer trickery. Hammond kept stalling because he's ham fisted/footed and F1 cars have very small clutches not designed to be slipped/ Quote Link to comment Share on other sites More sharing options...

Guest ugp Posted January 16, 2012 Share Posted January 16, 2012 (edited) F1 cars do still have a hand clutch on th steering wheel for launches!! I've just looked that up on wikipedia, it would appear they do still use them for launches, something to do with clutchless systems being banned. My bad.

Tyson Posted January 16, 2012 Share Posted January 16, 2012 The drivers do not manually use the clutch apart from moving off from standstill from this website http://www.f1technical.net/articles/66 Quote Link to comment Share on other sites More sharing options...

johnny g Posted January 16, 2012 Share Posted January 16, 2012 F1 cars also "seamless shift", with no loss in transmission to the drive-train. I'm not entirely sure how that happens, but it's something very fancy with 2 clutches AFAIK. Quote Link to comment Share on other sites More sharing options...

There's a small bit about it on here. http://www.formula1.com/inside_f1/understanding_the_sport/5280.html Quote Link to comment Share on other sites More sharing options...
