Mercedes AMG F1 W05

They're using the engine to recover energy through the MGU-H when braking.

I wonder if they are able to harvest not only during braking but also during acceleration as to implement a crude version of traction control. The cameras on the car are probably precise enough to detect wheel spin.

I remember rumors last season on this very forum of Red Bull using such a system.

I suggested that last year some time, the rules regarding ERS implementation and communication are complicated, lots of discussion in the engine thread.

The Mercedes is making the off throttle blown diffuser sounds a la red bull mid corner.

As i understand, it's not the same as the last year. They do it for mid-corner drivability, but last year they cut the ignition (they wasted fuel) and now they cut the injection (they save fuel). This topic was commented in Test Jerez Day 2 - Ted's Notebook - http://www1.skysports.com/watch/video/9 ... s-notebook

I know it`s off topic but regarding this matter rumors says they are trying (in conjunction with the injection cut-off) some clever MGU-K mappings, like RB9 did last year, in order to improve traction mid and out of the corner ... and btw. that sound is MGU-K harvesting rather than cut-off ignition, IMHO

Clearly they are ahead of the game, from reliability side view ...

I'd say that anything other than smoothing out the torque delivery of the engine, using the ERS, will be quickly detected by other teams and reported to the FIA, which will of course ban it. On the technical side, I think it's very easy to make a traction control device by detecting wheelspin from the current drawn by the electric motor, but given that all maps are available to the FIA, it's very unlikely

9.3 Traction control :
No car may be equipped with a system or device which is capable of preventing the driven
wheels from spinning under power or of compensating for excessive torque demand by the
driver.
Any device or system which notifies the driver of the onset of wheel spin is not permitted.

I don't see why they'd need the camera's to detect wheel spin, they were probably only really interested in the thermal properties of the tyre.

Everything they need to detect wheel spin is probably already built into these new engine systems, can't see why they wouldn't monitor the input torque on the drive shafts, surely when traction isn't lost you would see a certain level, so they could just program the MGU-K to apply load onto the drive shafts until the desired torque input was achieved ?

Again whether this directly breaks the rules outlines I don't know, as they could say the MGU-K is just operating within it's parameters to harvest energy as efficiently as possibly, secondary effect from this is that is limits wheel spin. I'm sure there are clever ways to get around detection or the rules...

I think Mercedes technical team additions over the last few years is starting to pay off. The new suspension solution from Aldo Costa with essentially one lower wishbone on the front suspension is proof of this. It's a neat little solution that will provide some extra DF at the front compared to a car with the typical wishbone configuration.

[turbof1]

Even more front df?

I wonder how they balance it out at the rear.

[Holm86]

I cant see it creating downforce. To me it looks more like its diverting air downwards. The leading edge is much higher than the trailing edge.

[Blackout]

That reminds me of the FW-16 rear suspensions. But i'm not sure; did that Williams have an Y shaped upper arm at the rear, like the Merc, or was it just a normal triangle with a larger trailing part ?

No triangle here

Stunning footage, very nice.

[Shrieker]

What an awesome vid that !

[Mr.G]

The engine sounds quite worse than in Jerez.

[stefan_]

The engine was probably turned down when they did the shake down at Silverstone.

Green light is always on. What does it mean - no ERS in use? Empty battery?
