Seamless for R27 too!

manchild · Post 24 Jan 2007, 20:20

The R27 will feature an instantaneous gearchange (IGC) gearbox for the first time. This technology has already been run by other teams, but will make its track debut in Melbourne. The unit has already completed thousands of kilometres of reliability running in a hybrid car, with promising results.

Now I'm relaxed... I though seamless gearbox is something that might be Ferrari's advantage but seeing the aero of both cars it looks to me that they don't have any advantage apart from tyre-suspension experience.

It would be great if we knew are there any similarities/differences in these systems at Honda, Williams, Ferrari, Renault (perhaps someone else will have it).

Another thing... what kind of gearboxes will use customer teams? Isn't few months after engine deal to little time to design and develop gearbox to fit new engine and tune it up with ECU? Will they get gearboxes too? How is that usually done?

toyota also will have a seamless gearbox, a fruit of the cooperation with williams

For what I've read Renault is going to use a titanium gearbox, difficult to make but very, very reliable.

Ferrari's is carbon fibre, as well as McLaren's, but that's not seamless.
Anybody know why?

The team to beat is Renault, no doubt about it...

are seemless gearbox's just quicker shifting?
when you say that ferrari and mclaren use carbon fibre gearbox's, whats carbon fibre in them?

Seeing as they all have seamless, or at least claim to have it, then the advantage of actually having it is nullified.

So now the two fastest cars of 2006 have this gearbox...

a scary though considering Mclaren, and Honda already had this...

And I believe the difference between that of seamless shift and a normal box ranges from 20-30 seconds in a race.

Casing, axles and gears are steel.

yes, but seeing as how if you dont have it you will be slower than those who DO have it,and in racing being slower is not good, so i guess having it is the advantage

and by the way, does SA have the seamless gearbox as well ? or will Honda only "provide" and "share" their chassis and aero development ?

and im guessing as well that spyker doesnt have it ? or do they ?

The gearbox casing is carbon fibre

Given the different rates of expansion I would imagine this may create some unique problems when trying to mate a composite gearbox to a metalic engine block.

I think all present teams excluding Spyker are running seemless shift gearbox and even Spyker may use one as a benefit of there engine partnership with Ferrari

Has that been confirmed now, or is it still one of the rumors floating around the internet?

Its confirmed, it was very much a part of their engine deal with Williams

Booth Ferrari and McLaren gearbox is seamless, packed in carbon fibre casing. Look like there is no problem with different thermal characteristics between engine and gearbox because this carbon fibre gearbox is in use long time. First carbon fibre gearbox in F1 was made by Bernard for Ferrari team more or less in same time when he make sequential gearbox, maybe one year later, I am not sure.
To make a gear shift with "traditional" sequential gearbox, you need 15-25 milliseconds, depends on sophistications and quality of gearbox (Ferrari's gearbox's are always the best and fastest, in opinion of insiders) . For seamless shifting you need only few milliseconds. During each shift powertrain loose some power what you can feel very well in your car. Point is to make this period without power on wheels as short as possible. If driver in F1 car have to shift gear 800 time during the race, team can make nice time saving thought the race.

About team to beat.... I'm not so sure. Renault is good but drivers.... Fesicela is a pussy, and always is somebody els fault, not his fault. Heikki will need few years to mature, and then will be a different story. Tim to beat - Ferrari.
