Heidfeld downshift behaviour

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Heidfeld downshift behaviour

Post

Watching last Bahrein Grand Prix I noticed (via on-board camera) that Heidfeld was very "gentle" on his BMW gearbox when downshifting (he did not pass from 7th to 2nd with 5 instantaneous blips of the left paddle, he let some moment between each downshift, letting the revs go down).

I think this is due to the still present fragility of the new seamless gearbox.

Anyone did notice this?

Correct me if I'm wrong and the 2007 regs are different, but IIRC the ECU has built-in "veto" power over each gearshift. So a driver can simply flick down 5 times, and the ECU will shift down whenever the engine/gearbox can take the abuse.

IIRC that is not possible anymore since 2004 or 2005.

I would have to look in the FIA technical regulations but there is a certain time that musn`t be exceeded between operating the paddle and the actual shift.
Easy on the Appletini!

Look it up, it's article 9. It doesn't even say anything about gearshift time anymore. I remember the older regs mentioned max/min shift time.

Actually, article 9 doesn't even say "automatic transmissions are forbidden"
