2014 Steering wheel display

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

We usually have a steering wheel comparison thread with the wheels all in one place. I think there have been a few steering wheel pics & comments in the car threads. I'll move them into here if members highlight any steering wheel posts in car threads using the "report" button.

It's interesting to see that half the field will be using this, even toro rosso, while the other half chooses not to.
It does look like a very neat display. It was about time that drivers could get a proper visual representation, including graphs. I hope it isn't too distraction, but I think especially on the straights it would be handy to do a quick check.

Also Richard, this isn't the steering wheel itself. It's just the display that ussually goes into the wheel, but can be seperately mounted somewhere else.

yeah... you see I appreciate the effort, but if you checked the head post a bit better you'd notice that it's the same video.

This is not the same video as in the thread already.

Windsor just chats a little about it. Look from about 5 minutes in.

Windsor: "it isn't touch screen..."

Yeah, I don't think touch screen would be a good idea with gloves, especially not the kind of gloves f1 drivers have :P.

Really not that impressive. Companies have been making advanced dashes for quite some time. My new favorite is Motec's new color dash. Motec dash's can also act as the datalogger too, but that wouldn't be powerful enough for what the teams require. Still though, this is one area that F1 is having to catch up to. http://www.youtube.com/watch?v=MJt6uLqKga8

The McLaren Display looks awesome! =D>
Are the other teams developing in-house solutions or going with another vendor?
Here's a picture I got from a Moto2 bike last year, just for comparison...

I would imagine they're required to use the MES unit. I honestly don't see much purpose for the larger display unit, apart from laptime, speed and gear information, what other information do the drivers really need when the pitcrew are informing them of every decision anyway? It seems more suited to endurance racing.

On topic: the new one is 100 grams heavier than the old one :) Newey must be furious about that. Hence, RB10 gets the old one.

Off topic: I've seeb lab prototypes of BMW, done by Johnson Controls - this is really amazing. Out on the market in few years.

Just out of curiosity, could they hook that up to some sort of media player while waiting in the pitbox? I'd definitely see some drivers picking up a movie or an episode from their favorite show before exiting the box, just to get the nerves down.

on teds notebook he mentioned about these. he said a lot of the drivers aren't actually interested in them as they are only really interested in times (beyond rpm etc). which is prob why some have stuck with there old standard wheels as it displays all they want to know. And i agree. Most of that stuff is more relevant to the engineer and can then tell the driver on a need to know.

The generation of formula where this would of actually been of any use has been and gone. IMO its a tool which has come too late an as such isn't needed now

Rosberg mentioned about having it in an interview, but he talked about his wheel is his own design. Lewis designs his too, so does anyone know if he has also gone for this as well?

And this is the best shot of Hamilton's wheel i could dig from the car thread:

I can't make really sure, but it seems like the same display. Surely there's someone around who knows better or has a better pic of the cockpit with Lewis at the wheel.
