Then you're carrying twice as many (heavy) battery packs as you need!

Anyway if the generator is as efficient as Diesel suggests then my suggestion is void and it's easy to harvest the energy.

[feynman]

The McLaren KERS in 09 had a stated battery capacity of 160%, which was the minimum required to maintain 100% availability for any given lap.

Don't know what they, or Red Bull, are running this year, but I'd have to imagine it to be in that ballpark.

[shamikaze]

Correct,
If you would have 150-160% of allowed capacity in battery-capacity, it should suffice.

Remember, this is F1, so liekly that they replace the batteries after race-weekend, so they don't bother too much with battery-life (there goes the "green-initiative).

Also, every single point of deceleration is an opportunity to charge your KERS. Only the total amount of kJ to be used in & single lap is limited, not the amount of kJ stored in the batteries at any point in the lap.

You perfectly could have your batteries at 30% charged when crossing the finish-line, but from that point on, you are allowed to deploy them for 6 seconds. Your batteries at that moment only hold 2sec's worth of energy, but not you worry, since the first corner offers you a re-charge opportunity to bring them to 90% anyway. Or vice-versa, your batteries are still 95% charged at the last corner, but you only have 1sec worth of deploy-time left so that will not make you drop below 70%. You use the KERS before you cross the line, restart your lap with a full 6 sec's again and can keep on deploying KERS untill either you run of out track-space, out of battery or out of deploy-time. Whichever comes first

Vettel said, just before the race, that RBR had replaced the KERs batteries after qualifying. As cars are supposed to be in Parc-ferme, and not worked on, how was this allowed?

Is there a safety clause that would allow it?

I thought he was joking, he had that smile on his face like when he was asked why he didn't use KERS on his fast lap a few races ago, he said 'emm, couldn't find the button' haha

Parc Ferme Regulations

The FIA used to make the Parts Changed Report available within the Race Report in its Media Centre section, but they no longer do.

As an example, this is what the teams changed in Parc Ferme at Singapore in 2010:

Code: Select all

The following components were replaced during the Parc Fermé:

Scuderia Ferrari Marlboro team:
Car 07: Engine Gearbox Both components have been replaced with the approval of the FIA technical delegate following a written request from the team concerned, this being in accordance with Article 34.1 of the 2010 Formula One Sporting Regulations. But as the replacement engine will be the ninth new engine used by Felipe Massa during the 2010 Championship, the driver dropped ten places on the starting grid at this Event according to Article 28.4a of the 2010 Formula One Sporting Regulations. Further the engine he used during the qualifying session may not be used during any future qualifying session or race with the exception of the last Event of the 2010 Formula One World Championship. Also the gearbox change was not in compliance with Article 28.6a of the 2010 Formula One Sporting Regulations and the driver concerned should drop five places on the starting grid of the Event.

1) What is meant by: "stated battery capacity of 160%".

2) Wouldn't the management unit not control when the batteries are charged? When the batteries are full the energy is not generated or if more consistent braking is required, then the energy is dissipated in a resistor pack.

Brian

Think it means that it is charged for more than a laps worth, so 100% is one lap and 160% is one and a half (ish) to ensure that it never runs out

[hardingfv32]

This would pertain to grouping your per lap usage on a start/finish straight?

Has anoyone wondered if their DRS is designed not to be as effective as it could be? So they can still use it in the race, but in qualifying can use it more to drop the drag but still maintain a reasonable level of downforce on the car? So instead of losing a lot of downforce, they lose less but are able to use it more and they have achieved a fine balance between it?

Or that it is more efficient?

To me, the Mclaren one looks like it will still create a lot of downforce when being used, and it's the hardest to see when it is being used also.

I read the Horner stated that they were using the tyres better than everyone else for qualifying, but that you cannot do it in the race, so I'm assuming this has something to do with suspension set-up, maybe their softer setting is getting more from the tyre?

I think they just can't push the Pirellis as hard in the race as they can in qualifying.

[hardingfv32]

They use a "smaller flap" rear wing setup. These are said to provide less drag when open and less downforce when closed. So, yes, car balance will not be upset as much between open and closed DRS compared with most of the other competitors.

If we agree that RB is the fastest car in qualifying and still the fastest car at the start of the race (relative to the competition), then can we assume the car is handling perfectly in both situations?
How can this be if the DRS is open much of the time during qualifying and always closed during the race (assuming they are leading)?

What has change between qualifying and the start of the race? I think they can only add fuel.

Brian

[SiLo]

It's a head scratcher for sure!

I can understand that maybe they can push the tyres a bit harder during qualifying, but not to that extent.

[marcush.]

i´m sure there is more to gain using the DRS for creating two usable setups for the lap instead of using it as a drag reduction device.The first option will give an advantage for the whole lap as you can bridge the gap between slower corner optimum setup and quicker ones.the second option will give you a compromise setup with a little drag reduction on the straights .
RedBull is adding rear downforce for the race in the quick corners with this approach ...a shift to understeer if everything is according to the textbook (all tyres loaded to the same potential giving neutral balance)and adding more df plus the added weight of a filled up car would result in a marginal rear tyre.So maybe it´s not a balance shift at all but just a loss of ultimate performance due to the added drag they are carrying?
