I don't see how they can mount the larger, wider, more rearward wing without a beam wing.

they will be NO beam wing.

Agreed, that was really hard to read via Google Translate and left me none the wiser.

There is always the technical regulations on the FIA website.

A direct quote from 2017 FIA technical regulations "Other than the bodywork defined in Article 3.9.6, any bodywork behind the rear wheel centre
line which is more than 600mm above the reference plane, and less than 455mm from the car
centre line, must lie in an area when viewed from the side of the car that is situated between
150mm and 500mm rearward of the rear wheel centre line."

That to me suggests that the rear wing will be tilted rearwards, however I havent found anything about the beam wing.
It is hard to follow so technical phrases, so I may be wrong.

Also F1fanatic says that "At the moment the leading edge of the wing starts in line with the rear wheel centre line (RWCL), whereas for 2017 this will be shifted nearly 20cm rearward with extra room made to install its mounting pylon."

Image This poped up today. This suggests no beam wing, but doesn't say anything about the tilt of the rear wing.
But WOW, the diffusor height will be almost doubled!

Dam that diffuser is much bigger, about time we got decent size ones back in F1!

The other interesting thing I notice in the drawing is how much further away from the centerline the mirrors are mounted.

It makes complete sense but I wonder what cool tricks the teams will get up to with those long stalks they'll need.

The sidepods will be extended aswell from 1400 mm to 1600 mm in width, so probably they are gonna mount the mirrors on them like they are currently mounting them.

The mirrors are currently mounted to the chassis in front of the drivers (as per regs iirc):

they used to be like this (below) but im not sure if that is legal?

"3 All parts of the rear view mirrors, including their housings and mountings, must be situated
between 250mm and 500mm from the car centre line and between 550mm and 750mm from
the rear edge of the cockpit entry template."

The regs are open to different designs. Lets see which team goes which way.

So 550mm forward of the rear cockpit entry rules out the side pods unless the mirrors are on 550mm + long stalks (as imo they'd need to be quite beefy to be stable) as the sidepods usually start at the rear of the cockpit in the current cars.

Thoughts?

Side pods start further forward than the rear of the cockpit template because of the position of the side impact structure.
I think they will be in a similar position to what we have now if the driver can pass the test for visibility of text 10m behind the car that the FIA set. Will depend on how the rear wing obscures this test.

175mm is what's been used in 2009-2010, so that's not unheard of. What's more interesting is the length of it, which is also getting elongated. I'm not sure of exact numbers.

This could also have a big impact.

Will we get push rod back at the rear in order to accomodate the larger diffuser? Or will pull rod still leave enough room? back when double diffusers were around, many teams did not follow red bull with pull rod due difficulties fitting the pull rod over the double diffuser.
