Red Bull will rue their lack of KERS.

[myurr]

Didn't think this rule existed. It would be impractical to enforce for one thing.

One word (well acronym) - SECU.

It's easy to enforce.

Interesting that Horner has come out and said that Red Bull will suffer if they don't have KERS working in Malaysia. Reckon it's true or more lies from the chief propaganda officer?

why I can see the traction limited aspect of the KERS discussion, who says, that you can´t start only with KERS power, and feed in the power from the ICE later on.
60kw should be plenty to spin the wheels from standstill without aero to aid traction.
Controling the power release of en electric motor, considering the torque characteristic of an electric motor should be not too difficult - IMHO.
I´m not saying, that this is what they do, as I dunno, but i would not rule it out on technical terms.

I don´t think, that there is a speed limit for KERS engagement, as it would need to be written somewhere in the technical or sporting rules, and I have not seen any mention of it.

Just a thought

AFAIK KERS is controlled by an on/off button on the wheel. It does go through the clutch so I suppose you could feather it a bit, but they don't have much control with the clutch.

Also feathering the KERS with the clutch will waste energy that can't be used later in the lap.

I think feathering the engine with the accelerator pedal and the clutch would give more control. Then you can use the full KERS once you've got traction.

I know that most of the sketches flying around the internet show, that the KERS motor is connected to the crankshaft of the engine, but by the rules it does not has to be.

When there was talk about the "RBR start only KERS" it was something that crossed my mind. (I know that in the meantime the rumor has been put to bed)
Nevertheless, technically you could do something like this:

just replace the starter motor with the KERS motor, and you have a neat "start only KERS"

As for the other aspects:
While it is true and correct that the KERS function has to be operated by a "on-off switch", I don´t think, that this has to translate into a +60kw input on the rear wheels.
You can activate a controlled release rate by the push of this buttom - IMHO
(open loop control)

Note that in the technical rules, it is explicitely stated that clutches for the KERS system are not subject to the limitations for the "normal" clutch.

9.2 Clutch control :
The following applies only to the main drivetrain clutch or clutches, any clutch used exclusively as part of a KERS is exempt.

make of this what you like, but I can imagine some room for "creative engineering" here

[nacho]

McLaren had a setting in 2009 for the KERS power output in the steering wheel, but I think they mostly used full power most of the time.

[raymondu999]

So you're talking of a KERS "launch control?"

[747heavy]

let´s say "launch aid"

[nexusf1]

RBR will certainly suffer without KERS in Sepang - from what i've read the system was connected but just not working on the red bull. There was no CoG ballast advantage.

I think the tyres will be the bigger story personally - if RBR can qualify well and be good with their tyres, they'll be hard to beat regardless.

Seeing how this thread was started later than the other RBR KERS thread, this one is being locked because it's a bit redundant to say the least, and merging them would be a mess.

So please take this technical discussion here:
Start-only KERS?
