selecting 1st gear ??

[adam2007]

When a formula one driver selects first gear does he have to keep his foot on the brake or does the car start to move forward even though hes not on accelator? if you get what im saying

[Scotracer]

They keep their foot on the brake in case of any gradient. F1 cars work the same as any other sequential geared racer - they use the clutch for launches. So foot on brake, hold in the clutch and apply the right amount of juice.

They don't have an automatic transmission, which is seemingly what you're asking...

TJ – Thats maybe what he's asking but…

I believe it’s a reference to that when a road car is left in first gear on tick over it will creep forward. Note that if you were to press the brake and stop the car you’d need to press the clutch also as you’d stall if not. I’d assume this is the same in a race car.

OP – it is not exactly clear of what you’re asking, maybe try and rephrase your question.

And if the driver releases the clutch with 1st gear engaged, the engine will stall, right?

By the way, does anyone know idle rpm of an F1 engine? As far as I know it is in the region of 4000rpm, but the number might be completely wrong...

I don't think they have a clutch pedal but a clutch paddle on the steering wheel, under the gear shift peddles.

I won't swear to this so don't flame me... But I read an article somwhere in the past where the writer did one of those "layman driving an F1 car" articles. I believe it was a Toyota. Anyway, he claimed that the clutch was automatic.... That is, he idled it out of the pits just like driving an automatic (albeit with a high stall converter). When he accelerated, it slipped the clutch automatically just so until it locked.

Further, I remember when Hammond on Top Gear drove an F1 car (Renault?), it kept "kicking out of gear" which he said was the anti-stall software at work. It appeared to be the same situation as above but he wasn't aggessive enough on the accelerator. It would start to engage the clutch, pull the revs down, and then disengage the clutch again to keep from stalling. When he nailed it, the clutch locked, the tires lit up and everything worked as we've come to expect.

There's an antistall mechanism that should release the clutch once the revs drop enough, but it does not always work, something mr Barrichello has made a point of this season. Not sure about idle speed, my head says 6k, but not really sure

They don't have torque converters, they're not conventional autos. Rather automated sequential manuals.

Thanks Alejandro... I didn't mean to imply they had torque converters. What I meant to say was that the computer modulated the clutch so that it felt like driving a car with an automatic that had a high stall torque converter.

Oh I see. From what i've understood they're pretty much on and off, with the 'bite point' predefined based on driver preference, but i don't know for sure. I do recall Brundle saying that after driving the newer cars he felt the anti stall system made it next to impossible to play around with the clutch, if you tried to be gentle to say get a car out of a sand trap then the anti stall would kick in and pull out the clutch, so it was all or nothing for the most part. It didn't seem like the computer would be able to modulate it at all, from what he said, but again i don't know this for sure, it's just what i've assumed from watching and listening.

Why do the cars have that sudden but very short lurch when put in gear? I know the clutch is engaged other wise the engine would immediately stall or not not engage any gear. It seems a very hard lurch when they do.

i watned a site or link to knw abt a proper diffrences between normal cars n f1 cars formulated in table and chart form....pls help me so i will be greatful to u as it will help to get my uni degree...plsssssssssssssssssssssss rep asap.

My 2 cents on this... I ride a motorcycle and the same thing happens on the bike when you pull the clutch in and select first.

The multiplate clutch clearly has some friction even when the plates are separated so there is a small forward pressure when 1st is selected (and the slack is taken out of the chain).

F1 clutches are very small and really only designed to enable the car to start from stationary.

I have a gearbox design that uses no clutch or torque converter.
It has stepped ratios and is lighter and far more compact than the current 19th century layshaft boxes.
It would give no engagement lurch and would drive away smooth as inertia for the vehicle was established.
Gear changes would be as rapid as current but with the addition of power on constantly variable shift over lap.
Two top F1 gearbox experts have looked at it under confidentiality and have found no flaws.
Unfortunately vested projects and lack of resources is holding up development.

In other words you want a hand out without doing any actual work. Yea right.
