Seems like some potentially cool new tech...

At the Singapore Grand Prix two weekends ago, Red Bull driver Sebastian Vettel won by an unbelievable 32 second margin over his closest rival. Seriously, it's unbelievable. Now F1 experts believe that Red Bull Racing's F1 engineers may have invented a new kind of traction control that links the car's hybrid engine to its suspension — but no one knows for sure. The whole world is stumped.

Can you hear how the two engines both sound like they're grinding as the car comes out of the corner?P
There is a possibility, though, that Red Bull has managed to find a legal way of making some kind of traction. One theory, put forward by Racecar Engineering, supposes that Red Bull may have linked the hybrid KERS system to the suspension, getting around the problem of uniform ECUs and also of unchangeable engine maps.

Racecar Engineering starts with a simple proposition.P

It is theoretically easy to modulate the output torque and charging input torque to an electric motor/generator using capacitors, batteries, inductors and a feedback signal. Torque changes are instant and control is easy and legal.P
And goes on to explain how the system would work.P

If torque were to be modulated in response to the normal force of the tires against the track (in response to shock pressure for example) significant unused traction potential could be recovered during high pressure phases (upside of bumps) and initiation of full wheel spin during low pressure phases (downside of bumps) could be delayed.P
The excellent F1 blog Axis of Oversteer points out that this theory is supported not just in Vettel's performance at Singapore, but also with Red Bull's history with their hybrid system.P

You might imagine a system like this would require extra sensors and controllers. While the KERS system is separate from the auxiliary electrical system, it is also known that the RB9 places especially high demands on its alternators which led to failures in the past (as constructed, materials were not up to demands).P
Beyond this stage of theory, as Axis points out, things start getting to levels of fake-moon-landing levels of conspiracy. It should be said, though, the Sebastian Vettel stated to the press before this most recent Korean Grand Prix that he had some kind of secret system in his car.P

We were playing around quite a lot with it in practice, but the first time it worked was in the race... I was quite confident other people would never figure out how we did it... We are pretty proud of the system we have because other people will never figure out how we’ve done it.P
When asked about his upcoming 2014 F1 car, Vettel gave this further encouragement.P

There's elements of this year's car going in to next year's...things like traction control will obviously be...P
He then trailed off into a grin, reports the Times of India.P

Its certainly fascinating, but heck its not the first time in F1, im glad there are a bit of secret work going on to push innovation if its true, I just wished in a sport like this it was a frequent thing to push technology further, the tyre situation is just stupid, you can really tell with the drivers hardly any one of them look like they are enjoying the race unless someone wins, or a rookie team does well, its all so political and financial
