Maybe they do just look smaller...I'd have to check the specs I guess, but J.A.W. is probably right as well.

According to the FIA there is no set specs for the size of the brake discs. At least none I can find in their rules .

Sorry but I think he´s not, to me they look pretty similar, it´s the wheel rim

Yeah, that's actually pretty funny.. as if you can see brake specs & deduce they're pretty much identical - from looking at pix!

What does Brembo have to say about it?
They'd surely know..

I watched some of the Nurburgring 24h this weekend, part of it had Alan McNish in with the commentators and they talked about FE. McNish said the battery hardware hasn't been changed since the first year of FE to this season, and since Audi came on board with the Schaeffer team, bringing people from the Audi WEC team, they have gained 15% battery efficiency, or an extra 6 laps per race, through the software. This was on Saturday evening, about 5 hours in, if anyone else was watching it on YouTube.

Yes it´s funny how you assume the brake discs are small based on a picture....

Seems likely that - no repeated hard braking from ~350 km/h, for a much longer race - would have a fair bit to do with it..

But if I post that same picture again along with a similar picture of a F1 car with 18´rins to compare, then a picture is not enough to see brake specs

If the diameter (including tyre) is claimed to be identical, at the very least you need a proper sideways photo for both and scaling them to an identical height. Otherwise it's just impressions.

[Andres125sx]

Agree, but they´re exactly same impressions wich motivated some people to assume FE discs are small, so a picture can be enough or not (I really don´t care) but some consistency will be much appreciatted

Interesting article(s) about batteries in FE

Funny indeed - that anyone would assume that Brembo would find it needful to fit F1-spec brakes.. to a piddling FE..

Who? Where did you read that?

Formula E
Brakes - Brembo package; bespoke carbon discs and pads 278 mm in diameter at the front and 263 mm at the rear, callipers and tandem master cylinder - brake-by-wire at the rear.

Formula 1

Each wheel must have no more than one brake disc of 278mm maximum diameter and 32mm maximum thickness.

They have the same diameter.

Thanks
I saw that but skipped on to the Technical regs and didn't find that there.

Size and capability are not the same thing. There’s a little more goes in to braking capability than disc diameter.

Manufacturing facilities may have infuenced the size as much as any performance criteria.

Probably because being a single spec series all the teams run the same brakes . I've not managed to work out why the tech tegs for FE cover so much for bodywork and other things they can't change. All it needs to say is don't modify the bodywork, surely?! I dunno, maybe brembo use the same sizes as F1 so they can re-use the moulds!?!
